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 the safety of the manufacturing process for weapon systems. The purpose of using weapon systems is to harm human life and destroy the property of hostile countries. Naturally, a weapon system involves explosives during its development and operation. As such, manufacturing processes for weapon systems have potential hazards of accidents that can cause fatal damages to humans or property. Some erroneous activities in the manufacturing process can produce dangerous results. For this reason, the safety of manufacturing processes in the defense industry domain 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 of safety integrity levels; selection of appropriate safety analysis methods; and execution of the analysis methods using SysML models. Using the results obtained in the study, one can identify the risk factors in a complex manufacturing environment in advance to take preventive actions against the potential loss that may arise.
