Abstract :
Production reliability is an integrated measurement of production ability of the continuum-state manufacturing system (CSMS), which is determined by the state of each process within. Based on the general stress-strength interference theory, a new model is proposed for production reliability evaluation of CSMS, which can calculate the system capacity under variable production tasks, together with the degradation of production capacity caused by the degradation of equipment has also been considered. The universal generating function is used to develop the model and procedure to evaluate the CSMS reliability. Case study of the servo valve process system is presented, the production reliability and the corresponding production reserves for equipment and system over time are provided.
