Model-Based Functional Safety Analysis of Manufacturing Processes for Weapon Systems

摘要

The present study aims to propose a method of carrying out the functional safety analysis to ensure thesafety of the manufacturing process for weapon systems. The purpose of using weapon systems is to harm humanlife and destroy the property of hostile countries. Naturally, a weapon system involves explosives during itsdevelopment and operation. As such, manufacturing processes for weapon systems have potential hazards ofaccidents that can cause fatal damages to humans or property. Some erroneous activities in the manufacturingprocess can produce dangerous results. For this reason, the safety of manufacturing processes in the defense industrydomain is more crucial than other general manufacturing domain. To deal with such a safety issue, in this research,we propose a model-based approach to ensuring the safety of the manufacturing process for the defense industry.The proposal is primarily based on the concept of functional safety and includes the three steps: determination ofsafety integrity levels; selection of appropriate safety analysis methods; and execution of the analysis methods usingSysML models. Using the results obtained in the study, one can identify the risk factors in a complex manufacturingenvironment in advance to take preventive actions against the potential loss that may arise.
