OBJECTIVE: Apply Model Based System Engineering (MBSE) tools to create a model representing the safety process required to develop and deploy advanced Navy munition systems. DESCRIPTION: Munitions (Missiles and Projectiles) require rigorous technical evaluation and assessment of safety-critical components and sub-components, including software. This currently involves the evaluation of the testing, evaluation, and verification of a munition’s safety-critical features by System Safety Working Groups (SSWGs) and official Navy Safety Technical Panels. These include the Fuze and Initiation Safety Technical Panel (FISTRP); the Software System Safety Technical Review Panel (SSSTRP), and ultimately the Navy’s Weapon System Explosive Safety Review Board (WSESRB). The WSESRB reviews the entire program’s plan to address safety-critical issues for the munitions to mitigate the risk or criticality of hazardous events. Many component-related artifacts such as architectural drawings are developed for SSWGs and Technical Panels and are reused throughout this process. Due to the heterogeneous nature of munitions and explosives, their manufacture, storage, delivery application, and operational use, coupled with safety requirements spanning current and future designs, there is a necessity to automate the processes that qualify their fielding. Currently processes are performed manually with no automated solution. Because automated solutions do not currently exist, the US Navy seeks advances in data and architecture design to develop a MBSE framework with structured data schemas for advanced munition safety analysis and management. In addition to integrating requirements (e.g., Department of Defense [DoD] explosive safety guidelines) and data generation (e.g., test configurations, test metrics, test results) through such techniques as Native Programming Language (NPL), a model [based upon a subset of Department of Defense Architectural Framework (DoDAF) like views] is expected that will enable multiple tiers of decision analysis. These tiers may include not only safety integration but impacts on munition performance and life cycle costs. The solution will provide a structure for integrating requirements and data of differing ontologies from multiple sources (e.g., DoD, Department of the Navy (DoN), Department of Transportation (DoT)) as well as their architecture to model the complex processes, requirements, and test data for safety qualification of different munition configurations. The resultant technology should provide a recognizable model comprising elements of the Data Models, Operational Level Models, and System Level Models necessary to support safety data and risk and hazard analysis. The final product should provide a prototype digital model of the DoN safety framework that bridges relationships between explosive hazard classifications, explosive hazard mitigation and associated risks with requirements and testing processes. The final product shall also illustrate the decision analysis techniques that provide efficiencies. It is expected that a subset of existing munition program cases will be used to trace the conceptualized system performance across both operational and system safety level analysis events to support model validity and potential process efficiencies that could reduce development time and costs. Additionally, MBSE based tools that specifically support different analysis areas are expected (that is, support differing metrics or multi-tier analysis capability). An example of the analysis metrics would be in support of artifacts extracted from the FISTRP, SSSTRP, WSESRB, and Insensitive Munitions (IM) requirements and processes. Multi-tier analysis would look for bridging this safety perspective model with other munition/missile system engineering or design tools. PHASE I: Define the conceptual data model and architecture framework for modeling munition and missile safety development, test, and qualification process and analysis allowing for technology innovation. Demonstrate the process model concept meets the parameters in the Description and show feasibility through modeling and analysis. This period will include a static demonstration of use case applicability to illustrate the modeling of the processes to lay the groundwork for supporting program analysis. The Phase I Option, if exercised, will include the initial design specifications and capabilities description to build a prototype solution in Phase II. PHASE II: Develop and deliver a prototype active framework using the concept developed in Phase I. Demonstrate the prototype meets the parameters of the Description using a model centric approach. This prototype will result in a demonstration of multiple uses cases and perturbations that will emphasize tiered analysis in support of decision events. PHASE III DUAL USE APPLICATIONS: Provide the final product and remain positioned to expand the use cases as well as safety and fault tree based analysis capabilities. The development of the model is available to expand upon multi-tier decision support tools and to more closely couple design, manufacturing, and program management decision events with discrete and stochastic based risk analysis. Commercial applications would include safety critical industry processes, especially those operating under multiple requirement sources (e.g., Environmental directives - both Federal and local). Examples of possible industries might include Nuclear, Geophysical (Mining), or Chemical. REFERENCES: 1.
