Abstract

In many industrial systems, accidents result from equipment failures and human errors. The latter can thus be viewed as a form of system failure which must be identified and analyzed. In this paper, an industrial system made up of a brake press operated by a single operator is analyzed. A reliability Markov diagram including repair states is drawn to model the system. The probability of a work accident (failed state of the system) is calculated using fuzzy numbers. An innovative aspect of this study is that repair states for human failures are also defined and their repair rates are estimated. The equations of state of the system are then derived and solved. Thus, the probability of the system being in a failed state is calculated.
