Abstract
Maintenance and repair and the discussion of determining the optimal rate of production are two separate topics that today, due to the interdependence between them, are merged and are presented as two separate components. In this paper, the production system prone to unstable network failure is investigated, assuming the existence of perishable goods that have preventive and corrective net activities. The purpose of this article is to determine the optimal rate of production and consequently minimize the total cost of production, shortages, corruption, maintenance of preventive and corrective repairs, rework, and maintenance of goods over a long-time horizon. Uncertainty due to accidental machine failures has made solving such problems very complicated with mathematical models. Therefore, in this paper, the discrete event simulation tool and ARENA.14 software are used to calculate system performance indicators. Also, in order to evaluate the efficiency of the system and determine the optimal scenario, the data envelopment analysis technique has been used, the results of which show the efficiency of the proposed model.
