The Department of the Navy (DON) must design, deliver, and sustain increasingly complex system of systems, platforms, sensors, information and weapons that are responsive to rapidly changing operational and threat environments, and must do so under increasingly restrictive budgets and aggressive delivery schedules. This Digital Systems Engineering Transformation Strategy provides the approach the United States Navy and Marine Corps will pursue to achieve this objective. 

海军部（DON）必须设计、交付和维持日益复杂的的系统、平台、传感器、信息和武器，以应对快速变化的作战和威胁环境，并且必须在日益严格的预算和紧迫的交付进度下完成这些工作。本数字系统工程转型战略提供了美国海军和海军陆战队为实现这一目标将采取的方法。

In June 2018, the Department of Defense (DoD) released their Digital Engineering Strategy, intended to guide the planning, development, and implementation of digital transformation across the military services. The DoD Digital Engineering Strategy offered five strategic goals which, when taken together, constitute “what” is necessary to foster the use of Digital Engineering practices. The DoD Digital Engineering Strategy also stated that the military services must develop the “how” -- the steps necessary to apply Digital Engineering as a timely imperative. This document details the DON response, describing our vision, goals, processes, and delegated actions to implement Digital Engineering within the US Navy and Marine Corps.

2018年6月，美国国防部（DoD）发布了数字工程战略，旨在指导各军种数字化转型的规划、发展和实施。国防部的数字工程战略提供了五个战略目标，这些目标合在一起，构成了促进使用数字工程实践所需的 "内容"。国防部数字工程战略还指出，各军种必须制定 "如何做"--将数字工程作为一种及时的、必要的步骤。当务之急。本文件详细介绍了海军部的方案，描述了我们的愿景、目标、流程和授权行动，以便在美国海军和海军陆战队内实施数字工程。

The rate of commercial technological change, combined with global connectivity, exponentially improving computational speed, and software-based digital control systems allows allies and adversaries alike to innovate very quickly. The rate of innovation has broad and significant implications regarding maintaining military advantages, technical superiority, and superior decision speed. Our job as scientists, engineers, program managers, analysts and technicians supporting naval acquisition is to provide our customers with that decisive material and decision advantage. Any capability gaps identified by fleet campaign assessments will also require a distributed and connected maritime network solution across programmatic requirements.

商业技术变革的迅猛发展，加上全球互联，计算速度成倍增长，并且基于软件基于软件的数字控制系统，使盟友和对手都能很快地进行创新。创新速度对于保持军事优势、技术优势和卓越的决策速度具有广泛而重要的影响。 作为支持海军采办的科学家、工程师、项目经理、分析师和技术人员，我们的工作是为客户提供决定性的材料和决策优势。 舰队战役评估确定的任何能力差距，也将需要一个分布式和连接的海上网络解决方案，满足项目需求。

This Navy and Marine Corps Digital Systems Engineering Transformation Strategy shifts the practice of systems engineering from traditional document-centric activities to digital-centric activities. It supports common application across the Navy and Marine Corps, and encompasses provision and access to digital models and data applied in a Model-based Systems Engineering approach in order to improve the understanding, quality, consistency and timely delivery of warfighter capability across all domains, and across all stages of the program lifecycle. 

系统工程的实践从传统的以文件为中心的活动转向以数字为中心的 活动。它支持整个海军和海军陆战队的共同应用，其中包括在基于模型的系统工程中提供和获取数字模型和数据，在所有领域和项目生命周期的所有阶段，提高对作战人员能力的理解、质量、一致性和及时交付，并及时交付作战人员的能力。

Military research was formative in the invention, integration, and use of digital technologies, so using digital tools to conduct engineering is not new to our workforce or our industry partners. However, change does not come without challenges. Leadership advocacy, changes in business and acquisition practices, workforce training, and provision of data models and tools in secure, accessible environments will be necessary in order to succeed.

军事研究在数字技术的发明、整合和使用方面是成型的，因此使用数字工具进行工程设计对我们的劳动力或我们的行业合作伙伴来说也是顺理成章的。然而，变革并非没有挑战，为了成功，领导层的倡导、业务和采办实践的变革、人员培训以及在安全、可访问的环境中提供数据模型和工具将是非常必要的。

This document supports 2018 Navy Strategy to “build a more lethal force” and to “reform the Department for greater performance and affordability”. It also aligns with National Defense Strategy objectives to “continuously deliver performance at affordability and speed as we change the Department’s mindset, culture and management systems”, to “adopt our culture and processes to achieve a step change in lethality, affordability and velocity” and to “establish architecture superiority.” Furthermore, this document aligns with the Chief of Naval Operations guidance and Design for Maintaining Maritime Superiority 2.0 to “share data across the force and effectively leverage that increased awareness,” “enhance operational capability whenever and wherever possible”, and “as technology moves faster and as more tools become available, make sure that we can get things done.”

这份文件支持2018年海军战略，即 "建立一支更具杀伤力的部队 "和 "改革该部以提高性能和经济可承受性"。它还与国防战略的目标相一致，即 "在我们改变该部的思维方式、文化和管理系统的同时，不断提供可承受的性能和速度"，"采用我们的文化和流程以实现杀伤力、可负担性和速度的阶跃变化"，并 "建立架构优势"。此外，该文件与海军作战部长的指导意见和维持海上优势2.0的设计相一致，以 "在整个部队中共享数据，并有效地利用这种增强的意识"，"随时随地增强作战能力"，以及 "随着技术的快速发展和更多工具的出现，确保我们能够完成工作"。 

This Navy and Marine Corps Digital Systems Engineering Transformation Strategy authored within the offices of the Acquisition Executive of the Navy, addresses the approach to the assessment, analysis, design, development, modeling and simulation, configuration management, testing, and delivery of acquisition program capabilities for both the Navy and Marine Corps.

海军和海军陆战队数字系统工程转型战略在海军采购执行办公室内撰写，涉及评估、分析、设计、开发、建模和仿真、构型管理、测试，并为海军和海军陆战队提供采办项目能力。

This Naval Digital Systems Engineering Transformation Strategy is one part of naval digital strategies to evolve our workforce, processes and practices for improved modernization, upgradeability, and effect. 

该海军数字系统工程转型战略是海军数字战略的一部分，旨在发展我们的劳动力、流程和实践，以提高现代化、可升级性和效果。

Executive Summary

The Department of the Navy (DON) must change in order to improve how it delivers timely and effective capability to our warfighters. This requires altering how the DON designs, develops, validates, delivers, operates and sustains warfighting systems. This is not a choice; it is an imperative requiring immediacy and a sense of urgency. In support of that imperative, we choose to implement a Digital Engineering Strategy.

海军部（DON）必须改变，以改善其向我们的作战人员提供及时和有效能力的方式。这需要改变海军部设计、开发、验证、交付、运行和维持作战系统的方式。这不是一个选择；这是一个需要即时性和紧迫感的当务之急。为了解决这一迫切需求，我们选择实施数字工程战略。

Current engineering and acquisition processes do not suit the complexity, interconnectivity, and interoperability of modern warfare systems. Whereas past systems often were mechanical-based designs with few cross-system interfaces, modern systems implement software control systems with multiple interfaces supporting network-centric warfare tactics and strategies. The dynamic nature of military operations, and the increasingly complex systems performing it, compel rapid transition away from past practices of manually assimilating vast amounts of document-centric data and toward a digital data-centric approach.

当前的工程和采办流程并不能适应现代战争系统的复杂性、互连性和互操作性。过去的系统通常是基于机械的设计，几乎没有跨系统接口，而现代系统实施具有多个接口的软件控制系统，支持以网络为中心的战争战术和战略。军事行动的动态性质，以及执行军事行动的日益复杂的系统，迫使人们从过去手工处理的大量以文件为中心的数据的做法，迅速过渡到以数字数据为中心的方法。 

This US Navy and Marine Corps Digital Systems Engineering Transformation Strategy is

intended to transform systems engineering capabilities by using common, composable, interactive, model-based systems to store and exchange data, models, and information within and across programs. Digital Engineering uses models and authoritative data to coordinate and integrate all disciplines and phases of work for the life cycle of a platform or system. Digital Engineering allows engineers and leaders to better understand and assess complex choices, automates requirements traceability to achieve design satisfaction, and supports timely decision-making through integration, automation, visualization, and high performance computing. Specific objectives of this Digital Systems Engineering Transformation Strategy, which aligns

with the Defense Digital Engineering Strategy, June 2018, are:

美国海军和海军陆战队数字系统工程转型战略，旨在通过使用通用、可组合、交互式、基于模型的系统，在项目内及项目间存储和交换数据、模型和信息来转换系统工程能力。数字工程使用模型和权威数据，协调和整合平台或系统生命周期的所有学科和工作阶段。数字工程使工程师和领导者能够更好地理解和评估复杂的选择，使需求的可追溯性自动化，以实现设计满意度，并通过集成、自动化、可视化和高性能计算支持及时决策。该数字系统工程转型战略与 2018 年 6 月的国防数字工程战略相一致，其具体目标是：

This objective will be coordinated with the Chief of Naval Operations, Commandant of the Marine Corps and the Naval Chief Information Office in consonance with their digital transformation plans. Immediate tasks include identifying where to implement models for near-term acquisition program efficiency, improved systems interoperability, operational effectiveness and cost savings. Primary goals are to provide integrated, networked, upgradeable capability to the fleet faster, and to build an enduring research and development infrastructure that will enable future digital capability across the enterprise.

这一目标将与海军作战部长、海军陆战队司令和海军首席信息办公室协调，以配合他们的数字化转型计划。即时任务包括确定在何处实施模型以提高近期采购计划的效率、改进系统互操作性、运营效率和成本节约。主要目标是更快地为车队提供集成、网络化、可升级的能力，并建立一个持久的研发基础设施，使整个复杂组织体的未来数字能力得以实现。

This objective will establish a single, accessible, authoritative source of knowledge.

“Knowledge” is inclusive of data, models, engineering information, capabilities, requirements, and allocations of functions to existing programs of record or to emerging science & technology efforts. It also includes an enduring historical record of investment and prior technical decisions. Knowledge is accessed and used by all team members to develop, design, and validate operational capabilities, connecting disparate data sources within a common data framework. The vision for this knowledge source includes secure access and use by Navy, Marine Corps, and industry partners, using both unclassified and classified networks.

这一目标将建立一个单一的、可访问的、权威的知识源。 

"知识 "包括数据、模型、工程信息、能力、要求、以及对现有记录项目或新兴科技工作的功能分配。它还包括投资和先前技术决策的持久历史记录。所有的团队成员都可以访问和使用这些知识来开发、设计和验证运行能力，在一个共同的数据框架内连接不同的数据源。 这个知识源的愿景包括，海军、海军陆战队和工业伙伴可使用非机密和机密网络进行安全访问和使用。

OBJECTIVE 3 – Incorporate technological innovation to improve the engineering practice

This objective will institutionalize, expand, and accelerate the use of Digital Engineering to

support computational analysis of numerous alternatives early in the design process, and to

enable greater speed and utilization of Artificial Intelligence (AI) and Machine Learning (ML) in software development, deployment and sustainment. This enables near-real-time application

software revisions, while maintaining appropriate authority to operate (ATO) and configuration

control.

该目标将使数字工程的使用制度化、扩展和加速，以支持设计过程早期对众多备选方案的计算分析，并在软件开发、部署和维护中提高人工智能 (AI) 和机器学习 (ML) 的速度和利用率。这可以实现近实时的应用软件修订，同时保持适当的操作权限 (ATO) 和配置控制。

OBJECTIVE 4 – Establish the supporting infrastructure and environments for the Digital Engineering practice

This objective will modernize and connect digital environments readily available across the research and development enterprise. The digital environment must support secure system modeling, design, development, and live, virtual and constructive simulation and testing. Accomplishment will require connecting users across a high bandwidth network, linking the government workforce to tools, data and test venues across the enterprise, providing a digital environment necessary to perform the engineering business of the Navy and Marine Corps.

这一目标将使整个研发企业随时可用的数字环境现代化并连接起来。数字环境必须支持安全系统建模、设计、开发以及实时、虚拟和建设性的模拟和测试。实现这一目标，需要通过高带宽网络连接用户，将政府工作人员与整个企业的工具、数据和测试场所连接起来，提供执行海军和海军陆战队工程业务所需的数字环境。

OBJECTIVE 5 – Transform the culture and workforce to adopt and support Digital Engineering across the lifecycle

Digital Engineering is a paradigm shift requiring new skills, proficiency, knowledge, and practice across the engineering competency, as well as other supporting technical and acquisition functions. Leadership must provide the tools, processes, methods, training and the connective, collaborative environment necessary for Digital Engineering to succeed. They must also coordinate development and training of personnel with timely application of acquired skills in support of program priorities. This will accelerate delivery of benefit, support continued application of new skills, and prevent atrophy through lack of use. 

数字工程是一种范式转变，需要新的技能、熟练程度、知识和跨工程能力的实践，以及其他支持技术和采办功能。领导层必须提供数字工程取得成功所必需的工具、流程、方法、培训和相互关联的协同环境。还必须协调人员的发展和培训，及时应用获得的技能来支持项目的优先事项。这将这将加速效益的交付，支持新技能的持续应用，并防止因缺乏使用而萎缩。

Digital Engineering (Navy) - An integrated, computation-based approach that uses authoritative sources of system data and models across disciplines to support lifecycle

activities from concept through disposal.

定义：数字工程（海军）——一种基于计算的集成方法，使用跨学科的系统数据和模型的权威来源来支持从概念到处置的生命周期活动。

Model Based Systems Engineering (INCOSE) – Formalized application of modeling to support system requirements design, analysis, verification and validation, beginning in the conceptual design phase and continuing through development and later life cycle phases.

基于模型的系统工程（INCOSE）--通过正式应用建模来支持系统需求设计、分析、验证和确认，从概念设计阶段开始，一直到开发和后期的生命周期阶段。

Engineers devise and deliver solutions to problems. Systems engineers coordinate and integrate

teams, comprised of performers across varied technical disciplines, to deliver solutions while addressing challenges dealing with increased system complexity. As desired or required capabilities become more challenging, and as the number of potential solutions increases, systems engineers need tools to help them solve complex problems more quickly.

工程师设计并提供问题的解决方案。系统工程师协调和集成由不同技术学科的执行者组成的团队，以提供解决方案，同时应对应对日益增加的系统复杂性的挑战。随着期望或需要的能力变得更具挑战性，并且随着潜在解决方案数量的增加，系统工程师需要工具来帮助他们更快地解决复杂问题。

Digital Engineering is key to managing the development and delivery of increasingly complex and interconnected warfighting systems and desired capabilities. Historically, the DON systems engineering process has been document-centric, focused on individual program performance specifications and multiple program contract documents. Digital Engineering supports adoption of a new culture that uses digital models to analyze, design, test, produce, field, and sustain capabilities. The use of digital models supports early communication between technical disciplines. Development of the digital model(s) is a focused priority, and the performance specification, acquisition documentation, and other data artifacts are the result of the solutions identified by the modeling process. This approach will be more dynamic, more comprehensive, and will reduce the time and effort required to create recurring

documentation. It also helps reduce the number of formal contract deliverables and accelerates the acquisition process.

数字工程是管理开发和交付日益复杂和相互关联的作战系统和所需能力的关键。从历史上看，美国海军部的系统工程过程是以文件为中心的，专注于单个项目的性能规格和多个项目的合同文件。数字工程支持采用一种新的文化，使用数字模型来分析、设计、测试、生产、部署和维持能力。数字模型的使用支持技术学科间的早期交流。数字模型的开发是一个重点，而性能规范、采办文件和其他数据工件是建模过程中确定的解决方案的结果这种方法将更加动态、更加全面，并将减少创建重复文档所需的时间和精力。它还有助于减少正式合同交付物的数量，并加速采办过程。

Model Based Systems Engineering (MBSE) is formalized application of modeling to support system requirements, design, analysis, verification and validation activities. Applying MBSE enables a better understanding of all aspects of capability evelopment and system behaviors before generating the performance specification. Digital models have the potential to provide multiple integrated, linked, and related views at the subsystem, system, and system of systems levels. The integration of these views within the digital environment allows for a comprehensive and automated evaluation, which can identify inconsistencies or gaps in the model and rapidly assess impacts and mitigation options when changes are first considered. 

基于模型的系统工程（MBSE）是对建模的正式应用，以支持系统需求、设计、分析、验证和确认活动。应用MBSE能够在生成性能规范之前，更好地理解能力开发和系统行为的所有方面。 数字模型有可能在子系统、系统和系统的层面上，提供多种集成的、互相联系的和相关的视图。这些视图在数字环境中的整合允许进行全面和自动的评估，可以识别模型中的不一致或差距，并在首次考虑变化时，快速评估影响和缓解方案。

Additional benefits of Digital Engineering include creation and use of a single authoritative knowledge source within the digital environment. This authoritative knowledge source captures information from multiple inputs, which are integrated to form the system view. This approach ensures completeness and consistency of design data throughout the development, procurement, and sustainment life cycle.

数字工程的其他好处包括，在数字环境中创建和使用单一的权威性知识源。这个权威的知识源从多个输入中获取信息，这些信息被整合形成系统视图。这种方法确保了设计数据在整个开发、采办和持续保障的生命周期中的完整性和一致性。

“The pace of change also demands that we design ships with modernization in mind. The “core” of those future ships - the hull, and the propulsion and power plants - will likely be built to last for decades. To leave room for future modernization, we should buy as much power capacity as we can afford. On top of that hull and power plant, we must plan from the outset to modernize the “punch” -- the combat systems, sensors, and payloads -- at the speed that technological advances allow.”

"变化的步伐也要求我们在设计船舶时考虑到现代化问题。这些未来船舶的 "核心"--船体、推进器和动力装置--将可能建造后可以使用几十年。为了给未来的现代化留下空间，我们应该在我们能承受的范围内购买尽可能多的动力能力。在船体和动力装置的基础上，我们必须从一开始就计划以技术进步所允许的速度对 "拳头"--作战系统、传感器和有效载荷--进行现代化，在技术进步所允许的速度下"。

-CNO ADM John Richardson, “The Future Navy”, May 2017

The Department of the Navy (DON) embraces Digital Engineering as a means to maximize agility, interoperability, reusability, and scalability across the DON. This Navy and Marine Corps Digital Systems Engineering Transformation Strategy specifies activities necessary to enhance engineering acquisition practices within our enterprise. Our strategy aligns with Department of Defense Digital Engineering Strategy goals, shifts how we work from traditional document-centric activities to digital-centric activities, and informs designers, developers, managers, and technical authority stakeholders with continuous access to authoritative data.

Our Navy and Marine Corps teams have already started implementing digital approaches within our activities and acquisition programs. We will expand those efforts, working with our industry partners, to provide a standard of practice that delivers affordable, lethal capabilities to the warfighter at the speed of relevance.

美国海军部（DON）将数字工程作为一种手段，最大限度地提高敏捷性、灵活性、互操作性、可重用性和可扩展性。海军和海军陆战队的数字系统工程转型战略规定了必要的活动，在我们的组织内加强工程采购实践。我们的战略与美国国防部的数字工程战略目标协调一致，将我们的工作方式从传统的以文件为中心的活动转变为以数字为中心的活动，并告知设计者、开发者、管理者和技术权威等利益相关者，使他们能够持续获得权威的数据。

我们的海军和海军陆战队团队已经开始在我们的活动和采购项目中实施数字方法。我们的活动和采购项目已经开始实施数字方法。我们将扩大这些努力，并与我们的行业伙伴合作，提供一个实践标准，以尽快的速度为作战人员提供负担得起的、致命的作战能力。

The Department of the Navy (DON) must design, deliver, and sustain increasingly complex system of systems, platforms, sensors, information and weapons that are responsive to rapidly changing operational and threat environments, and must do so under increasingly restrictive budgets and aggressive delivery schedules. This Digital Systems Engineering Transformation Strategy provides the approach the United States Navy and Marine Corps will pursue to achieve this objective. 

海军部（DON）必须设计、交付和维持日益复杂的的系统、平台、传感器、信息和武器，以应对快速变化的作战和威胁环境，并且必须在日益严格的预算和紧迫的交付进度下完成这些工作。本数字系统工程转型战略提供了美国海军和海军陆战队为实现这一目标将采取的方法。

In June 2018, the Department of Defense (DoD) released their Digital Engineering Strategy, intended to guide the planning, development, and implementation of digital transformation across the military services. The DoD Digital Engineering Strategy offered five strategic goals which, when taken together, constitute “what” is necessary to foster the use of Digital Engineering practices. The DoD Digital Engineering Strategy also stated that the military services must develop the “how” -- the steps necessary to apply Digital Engineering as a timely imperative. This document details the DON response, describing our vision, goals, processes, and delegated actions to implement Digital Engineering within the US Navy and Marine Corps.

2018年6月，美国国防部（DoD）发布了数字工程战略，旨在指导各军种数字化转型的规划、发展和实施。国防部的数字工程战略提供了五个战略目标，这些目标合在一起，构成了促进使用数字工程实践所需的 "内容"。国防部数字工程战略还指出，各军种必须制定 "如何做"--将数字工程作为一种及时的、必要的步骤。当务之急。本文件详细介绍了海军部的方案，描述了我们的愿景、目标、流程和授权行动，以便在美国海军和海军陆战队内实施数字工程。

The rate of commercial technological change, combined with global connectivity, exponentially improving computational speed, and software-based digital control systems allows allies and adversaries alike to innovate very quickly. The rate of innovation has broad and significant implications regarding maintaining military advantages, technical superiority, and superior decision speed. Our job as scientists, engineers, program managers, analysts and technicians supporting naval acquisition is to provide our customers with that decisive material and decision advantage. Any capability gaps identified by fleet campaign assessments will also require a distributed and connected maritime network solution across programmatic requirements.

商业技术变革的迅猛发展，加上全球互联，计算速度成倍增长，并且基于软件基于软件的数字控制系统，使盟友和对手都能很快地进行创新。创新速度对于保持军事优势、技术优势和卓越的决策速度具有广泛而重要的影响。 作为支持海军采办的科学家、工程师、项目经理、分析师和技术人员，我们的工作是为客户提供决定性的材料和决策优势。 舰队战役评估确定的任何能力差距，也将需要一个分布式和连接的海上网络解决方案，满足项目需求。

This Navy and Marine Corps Digital Systems Engineering Transformation Strategy shifts the practice of systems engineering from traditional document-centric activities to digital-centric activities. It supports common application across the Navy and Marine Corps, and encompasses provision and access to digital models and data applied in a Model-based Systems Engineering approach in order to improve the understanding, quality, consistency and timely delivery of warfighter capability across all domains, and across all stages of the program lifecycle. 

系统工程的实践从传统的以文件为中心的活动转向以数字为中心的 活动。它支持整个海军和海军陆战队的共同应用，其中包括在基于模型的系统工程中提供和获取数字模型和数据，在所有领域和项目生命周期的所有阶段，提高对作战人员能力的理解、质量、一致性和及时交付，并及时交付作战人员的能力。

Military research was formative in the invention, integration, and use of digital technologies, so using digital tools to conduct engineering is not new to our workforce or our industry partners. However, change does not come without challenges. Leadership advocacy, changes in business and acquisition practices, workforce training, and provision of data models and tools in secure, accessible environments will be necessary in order to succeed.

军事研究在数字技术的发明、整合和使用方面是成型的，因此使用数字工具进行工程设计对我们的劳动力或我们的行业合作伙伴来说也是顺理成章的。然而，变革并非没有挑战，为了成功，领导层的倡导、业务和采办实践的变革、人员培训以及在安全、可访问的环境中提供数据模型和工具将是非常必要的。

This document supports 2018 Navy Strategy to “build a more lethal force” and to “reform the Department for greater performance and affordability”. It also aligns with National Defense Strategy objectives to “continuously deliver performance at affordability and speed as we change the Department’s mindset, culture and management systems”, to “adopt our culture and processes to achieve a step change in lethality, affordability and velocity” and to “establish architecture superiority.” Furthermore, this document aligns with the Chief of Naval Operations guidance and Design for Maintaining Maritime Superiority 2.0 to “share data across the force and effectively leverage that increased awareness,” “enhance operational capability whenever and wherever possible”, and “as technology moves faster and as more tools become available, make sure that we can get things done.”

这份文件支持2018年海军战略，即 "建立一支更具杀伤力的部队 "和 "改革该部以提高性能和经济可承受性"。它还与国防战略的目标相一致，即 "在我们改变该部的思维方式、文化和管理系统的同时，不断提供可承受的性能和速度"，"采用我们的文化和流程以实现杀伤力、可负担性和速度的阶跃变化"，并 "建立架构优势"。此外，该文件与海军作战部长的指导意见和维持海上优势2.0的设计相一致，以 "在整个部队中共享数据，并有效地利用这种增强的意识"，"随时随地增强作战能力"，以及 "随着技术的快速发展和更多工具的出现，确保我们能够完成工作"。 

This Navy and Marine Corps Digital Systems Engineering Transformation Strategy authored within the offices of the Acquisition Executive of the Navy, addresses the approach to the assessment, analysis, design, development, modeling and simulation, configuration management, testing, and delivery of acquisition program capabilities for both the Navy and Marine Corps.

海军和海军陆战队数字系统工程转型战略在海军采购执行办公室内撰写，涉及评估、分析、设计、开发、建模和仿真、构型管理、测试，并为海军和海军陆战队提供采办项目能力。

This Naval Digital Systems Engineering Transformation Strategy is one part of naval digital strategies to evolve our workforce, processes and practices for improved modernization, upgradeability, and effect. 

该海军数字系统工程转型战略是海军数字战略的一部分，旨在发展我们的劳动力、流程和实践，以提高现代化、可升级性和效果。

Executive Summary

The Department of the Navy (DON) must change in order to improve how it delivers timely and effective capability to our warfighters. This requires altering how the DON designs, develops, validates, delivers, operates and sustains warfighting systems. This is not a choice; it is an imperative requiring immediacy and a sense of urgency. In support of that imperative, we choose to implement a Digital Engineering Strategy.

海军部（DON）必须改变，以改善其向我们的作战人员提供及时和有效能力的方式。这需要改变海军部设计、开发、验证、交付、运行和维持作战系统的方式。这不是一个选择；这是一个需要即时性和紧迫感的当务之急。为了解决这一迫切需求，我们选择实施数字工程战略。

Current engineering and acquisition processes do not suit the complexity, interconnectivity, and interoperability of modern warfare systems. Whereas past systems often were mechanical-based designs with few cross-system interfaces, modern systems implement software control systems with multiple interfaces supporting network-centric warfare tactics and strategies. The dynamic nature of military operations, and the increasingly complex systems performing it, compel rapid transition away from past practices of manually assimilating vast amounts of document-centric data and toward a digital data-centric approach.

当前的工程和采办流程并不能适应现代战争系统的复杂性、互连性和互操作性。过去的系统通常是基于机械的设计，几乎没有跨系统接口，而现代系统实施具有多个接口的软件控制系统，支持以网络为中心的战争战术和战略。军事行动的动态性质，以及执行军事行动的日益复杂的系统，迫使人们从过去手工处理的大量以文件为中心的数据的做法，迅速过渡到以数字数据为中心的方法。 

This US Navy and Marine Corps Digital Systems Engineering Transformation Strategy is

intended to transform systems engineering capabilities by using common, composable, interactive, model-based systems to store and exchange data, models, and information within and across programs. Digital Engineering uses models and authoritative data to coordinate and integrate all disciplines and phases of work for the life cycle of a platform or system. Digital Engineering allows engineers and leaders to better understand and assess complex choices, automates requirements traceability to achieve design satisfaction, and supports timely decision-making through integration, automation, visualization, and high performance computing. Specific objectives of this Digital Systems Engineering Transformation Strategy, which aligns

with the Defense Digital Engineering Strategy, June 2018, are:

美国海军和海军陆战队数字系统工程转型战略，旨在通过使用通用、可组合、交互式、基于模型的系统，在项目内及项目间存储和交换数据、模型和信息来转换系统工程能力。数字工程使用模型和权威数据，协调和整合平台或系统生命周期的所有学科和工作阶段。数字工程使工程师和领导者能够更好地理解和评估复杂的选择，使需求的可追溯性自动化，以实现设计满意度，并通过集成、自动化、可视化和高性能计算支持及时决策。该数字系统工程转型战略与 2018 年 6 月的国防数字工程战略相一致，其具体目标是：

This objective will be coordinated with the Chief of Naval Operations, Commandant of the Marine Corps and the Naval Chief Information Office in consonance with their digital transformation plans. Immediate tasks include identifying where to implement models for near-term acquisition program efficiency, improved systems interoperability, operational effectiveness and cost savings. Primary goals are to provide integrated, networked, upgradeable capability to the fleet faster, and to build an enduring research and development infrastructure that will enable future digital capability across the enterprise.

这一目标将与海军作战部长、海军陆战队司令和海军首席信息办公室协调，以配合他们的数字化转型计划。即时任务包括确定在何处实施模型以提高近期采购计划的效率、改进系统互操作性、运营效率和成本节约。主要目标是更快地为车队提供集成、网络化、可升级的能力，并建立一个持久的研发基础设施，使整个复杂组织体的未来数字能力得以实现。

This objective will establish a single, accessible, authoritative source of knowledge.

“Knowledge” is inclusive of data, models, engineering information, capabilities, requirements, and allocations of functions to existing programs of record or to emerging science & technology efforts. It also includes an enduring historical record of investment and prior technical decisions. Knowledge is accessed and used by all team members to develop, design, and validate operational capabilities, connecting disparate data sources within a common data framework. The vision for this knowledge source includes secure access and use by Navy, Marine Corps, and industry partners, using both unclassified and classified networks.

这一目标将建立一个单一的、可访问的、权威的知识源。 

"知识 "包括数据、模型、工程信息、能力、要求、以及对现有记录项目或新兴科技工作的功能分配。它还包括投资和先前技术决策的持久历史记录。所有的团队成员都可以访问和使用这些知识来开发、设计和验证运行能力，在一个共同的数据框架内连接不同的数据源。 这个知识源的愿景包括，海军、海军陆战队和工业伙伴可使用非机密和机密网络进行安全访问和使用。

OBJECTIVE 3 – Incorporate technological innovation to improve the engineering practice

This objective will institutionalize, expand, and accelerate the use of Digital Engineering to

support computational analysis of numerous alternatives early in the design process, and to

enable greater speed and utilization of Artificial Intelligence (AI) and Machine Learning (ML) in software development, deployment and sustainment. This enables near-real-time application

software revisions, while maintaining appropriate authority to operate (ATO) and configuration

control.

该目标将使数字工程的使用制度化、扩展和加速，以支持设计过程早期对众多备选方案的计算分析，并在软件开发、部署和维护中提高人工智能 (AI) 和机器学习 (ML) 的速度和利用率。这可以实现近实时的应用软件修订，同时保持适当的操作权限 (ATO) 和配置控制。

OBJECTIVE 4 – Establish the supporting infrastructure and environments for the Digital Engineering practice

This objective will modernize and connect digital environments readily available across the research and development enterprise. The digital environment must support secure system modeling, design, development, and live, virtual and constructive simulation and testing. Accomplishment will require connecting users across a high bandwidth network, linking the government workforce to tools, data and test venues across the enterprise, providing a digital environment necessary to perform the engineering business of the Navy and Marine Corps.

这一目标将使整个研发企业随时可用的数字环境现代化并连接起来。数字环境必须支持安全系统建模、设计、开发以及实时、虚拟和建设性的模拟和测试。实现这一目标，需要通过高带宽网络连接用户，将政府工作人员与整个企业的工具、数据和测试场所连接起来，提供执行海军和海军陆战队工程业务所需的数字环境。

OBJECTIVE 5 – Transform the culture and workforce to adopt and support Digital Engineering across the lifecycle

Digital Engineering is a paradigm shift requiring new skills, proficiency, knowledge, and practice across the engineering competency, as well as other supporting technical and acquisition functions. Leadership must provide the tools, processes, methods, training and the connective, collaborative environment necessary for Digital Engineering to succeed. They must also coordinate development and training of personnel with timely application of acquired skills in support of program priorities. This will accelerate delivery of benefit, support continued application of new skills, and prevent atrophy through lack of use. 

数字工程是一种范式转变，需要新的技能、熟练程度、知识和跨工程能力的实践，以及其他支持技术和采办功能。领导层必须提供数字工程取得成功所必需的工具、流程、方法、培训和相互关联的协同环境。还必须协调人员的发展和培训，及时应用获得的技能来支持项目的优先事项。这将这将加速效益的交付，支持新技能的持续应用，并防止因缺乏使用而萎缩。

Digital Engineering (Navy) - An integrated, computation-based approach that uses authoritative sources of system data and models across disciplines to support lifecycle

activities from concept through disposal.

定义：数字工程（海军）——一种基于计算的集成方法，使用跨学科的系统数据和模型的权威来源来支持从概念到处置的生命周期活动。

Model Based Systems Engineering (INCOSE) – Formalized application of modeling to support system requirements design, analysis, verification and validation, beginning in the conceptual design phase and continuing through development and later life cycle phases.

基于模型的系统工程（INCOSE）--通过正式应用建模来支持系统需求设计、分析、验证和确认，从概念设计阶段开始，一直到开发和后期的生命周期阶段。

Engineers devise and deliver solutions to problems. Systems engineers coordinate and integrate

teams, comprised of performers across varied technical disciplines, to deliver solutions while addressing challenges dealing with increased system complexity. As desired or required capabilities become more challenging, and as the number of potential solutions increases, systems engineers need tools to help them solve complex problems more quickly.

工程师设计并提供问题的解决方案。系统工程师协调和集成由不同技术学科的执行者组成的团队，以提供解决方案，同时应对应对日益增加的系统复杂性的挑战。随着期望或需要的能力变得更具挑战性，并且随着潜在解决方案数量的增加，系统工程师需要工具来帮助他们更快地解决复杂问题。

Digital Engineering is key to managing the development and delivery of increasingly complex and interconnected warfighting systems and desired capabilities. Historically, the DON systems engineering process has been document-centric, focused on individual program performance specifications and multiple program contract documents. Digital Engineering supports adoption of a new culture that uses digital models to analyze, design, test, produce, field, and sustain capabilities. The use of digital models supports early communication between technical disciplines. Development of the digital model(s) is a focused priority, and the performance specification, acquisition documentation, and other data artifacts are the result of the solutions identified by the modeling process. This approach will be more dynamic, more comprehensive, and will reduce the time and effort required to create recurring

documentation. It also helps reduce the number of formal contract deliverables and accelerates the acquisition process.

数字工程是管理开发和交付日益复杂和相互关联的作战系统和所需能力的关键。从历史上看，美国海军部的系统工程过程是以文件为中心的，专注于单个项目的性能规格和多个项目的合同文件。数字工程支持采用一种新的文化，使用数字模型来分析、设计、测试、生产、部署和维持能力。数字模型的使用支持技术学科间的早期交流。数字模型的开发是一个重点，而性能规范、采办文件和其他数据工件是建模过程中确定的解决方案的结果这种方法将更加动态、更加全面，并将减少创建重复文档所需的时间和精力。它还有助于减少正式合同交付物的数量，并加速采办过程。

Model Based Systems Engineering (MBSE) is formalized application of modeling to support system requirements, design, analysis, verification and validation activities. Applying MBSE enables a better understanding of all aspects of capability evelopment and system behaviors before generating the performance specification. Digital models have the potential to provide multiple integrated, linked, and related views at the subsystem, system, and system of systems levels. The integration of these views within the digital environment allows for a comprehensive and automated evaluation, which can identify inconsistencies or gaps in the model and rapidly assess impacts and mitigation options when changes are first considered. 

基于模型的系统工程（MBSE）是对建模的正式应用，以支持系统需求、设计、分析、验证和确认活动。应用MBSE能够在生成性能规范之前，更好地理解能力开发和系统行为的所有方面。 数字模型有可能在子系统、系统和系统的层面上，提供多种集成的、互相联系的和相关的视图。这些视图在数字环境中的整合允许进行全面和自动的评估，可以识别模型中的不一致或差距，并在首次考虑变化时，快速评估影响和缓解方案。

Additional benefits of Digital Engineering include creation and use of a single authoritative knowledge source within the digital environment. This authoritative knowledge source captures information from multiple inputs, which are integrated to form the system view. This approach ensures completeness and consistency of design data throughout the development, procurement, and sustainment life cycle.

数字工程的其他好处包括，在数字环境中创建和使用单一的权威性知识源。这个权威的知识源从多个输入中获取信息，这些信息被整合形成系统视图。这种方法确保了设计数据在整个开发、采办和持续保障的生命周期中的完整性和一致性。

“The pace of change also demands that we design ships with modernization in mind. The “core” of those future ships - the hull, and the propulsion and power plants - will likely be built to last for decades. To leave room for future modernization, we should buy as much power capacity as we can afford. On top of that hull and power plant, we must plan from the outset to modernize the “punch” -- the combat systems, sensors, and payloads -- at the speed that technological advances allow.”

"变化的步伐也要求我们在设计船舶时考虑到现代化问题。这些未来船舶的 "核心"--船体、推进器和动力装置--将可能建造后可以使用几十年。为了给未来的现代化留下空间，我们应该在我们能承受的范围内购买尽可能多的动力能力。在船体和动力装置的基础上，我们必须从一开始就计划以技术进步所允许的速度对 "拳头"--作战系统、传感器和有效载荷--进行现代化，在技术进步所允许的速度下"。
