ABSTRACT

Vulnerability reduction measures are taken during the early stage distributed ship system design process to ensure the availability of the required systems in a damaged state. Traditionally these vulnerability reduction measures are based on design rules or best practices resulting from past experiences. Therefore, the measures are not per definition applicable for future warships, as both the system concepts and operational environment changes. Recently developed vulnerability assessment methods are able to determine the vulnerability of a design early in the design process. With the integration of these methods in the early stage design process, the results of the analysis can be used to generate less vulnerable distributed ship system designs. This paper proposes an integral and holistic approach to optimisation of the design variables and distributed networks as these are becoming increasingly interdependent. The result of this approach is a model which generates distributed ship system designs consisting of component positions, a topology and routed connections based on a pre-defined system configuration and constraining physical architecture. Five testcases were conducted using this model, showing the necessity of the integral and holistic approach as the extent to which the contemporary design rules are implemented depends on the network complexity and operational environment.

摘要

在分布式船舶系统设计的早期阶段就采取了脆弱性降低措施，以确保所需系统在受损状态下的可用性。传统上，这些减少漏洞的措施是基于设计规则或从过去的经验中得出的最佳实践。因此，这些措施不适用于未来战舰的定义，因为系统概念和操作环境都会发生变化。最近开发的漏洞评估方法能够在设计过程的早期确定设计的漏洞。通过在早期设计过程中集成这些方法，分析结果可用于生成不易受攻击的分布式船舶系统设计。本文提出了一种整体和整体的方法来优化设计变量和分布式网络，因为它们变得越来越相互依赖。这种方法的结果是一个模型，该模型生成分布式船舶系统设计，包括组件位置、拓扑和基于预定义系统配置和约束物理架构的路由连接。使用该模型进行了五个测试用例，显示了整体和整体方法的必要性，因为现代设计规则的实施程度取决于网络复杂性和操作环境。基于预定义系统配置和约束物理架构的拓扑和路由连接。使用该模型进行了五个测试用例，显示了整体和整体方法的必要性，因为现代设计规则的实施程度取决于网络复杂性和操作环境。基于预定义系统配置和约束物理架构的拓扑和路由连接。使用该模型进行了五个测试用例，显示了整体和整体方法的必要性，因为现代设计规则的实施程度取决于网络复杂性和操作环境。
