ABSTRACT
Providing the required robots is an important issue of availability of a complex robotic production system, which is important for system utility improvement. In an advanced production system, the estimation of the required number of robots can be performed through different approaches. One of the realistic autonomous robot estimation methods is based on the system’s reliability and taking into consideration the system operating environment. To forecast the required number of robots in the future for the existing production system, in some cases, the assumption of a constant failure rate does not differ much from the assumption of a nonconstant failure rate, and can be made with an acceptable error. In this chapter, we study a renewal model used in estimation of robots for nonrepairable components. The effectiveness of the proposed integrated reliability evaluation model is worked out in an implementation. A multiple autonomous robot production system is proposed so that robots may encounter failures requiring replacement with a new one. The arrangement of multiple robots and work stations lead to a complex system configuration. Failure of any component of the system results in the whole system stop functioning, violating on-time product delivery and proper fulfillment of demands.
