Computer aided dependability analysis of vehicle operation based on priority and event sequencing

Abstract

The analysis of failure and repair states which relate to the vehicle operation has becoming of increased importance in intelligent transportation system and safety. Monte Carlo method is a powerful and adaptive tool to evaluate the dependability of vehicle operation whose subsystems and/or components which follow to arbitrary failure and repair distributions. We had developed a computer software, Dependability Simulation System (DSS) to evaluate the dependability of vehicle operation in traffic system through simulation, which uses to estimate the reliability, maintainability, MTTRF and MTBCF (MMBCF) parameters. The computer aided dependability analysis of vehicle operation which conducted in this study is based on a proposed priority of subsystems and/or components and event sequencing. The simulation results clearly demonstrated the potential and feasibility to describe the succession of vehicle operation in traffic system with the software.
