Integrated production and maintenance planning for closed-loop manufacturing assembly system with deteriorating machines

This paper presents an optimal integrated production and maintenance planning for a closed-loop manufacturing assembly network model. This study aims to design a production and maintenance model and reduce the total objective cost. The network model is subjected to machines with failure rate. Without maintenance strategies, failure rate is fluctuated with the deterioration of machines. The implementation of preventive maintenance in the manufacturing process can reduce the defective rate of the items, prevent the sudden breakdown of the machines, and play a very important role in the production of the product and the safe operation. By calculating the proposed model, we can cut down the cost of the closed-loop manufacturing network by 4.37%. The numerical results highlight the availability of the method. The proposed model reduces the total cost and ensures the efficient and safe operation of the manufacturing process.
