Abstract: Owing to the equipments deteriorate along with the production activities in the manufacturing system,its reliability and product quality decrease accordingly.Maintaining the equipment at an appropriate time can not only guarantee the product quality,reduce the production cost,but also avoid the loss caused by equipment failure.A dual maintenance mode of corrective maintenance and preventive maintenance was proposed based on the equipment deterioration rate for a parallel production system with multiple periods,product types and machines.A joint model of periodic production batch and a periodic maintenance planning was carried out based on the production and inventory capacity,setup cost,production cost,storage cost,shortage cost and maintenance cost.Then,a task unit planning based hybrid heuristic algorithm was designed to solve the model efficiently.The validity of the model and algorithm was verified based on extensive instances,and the experimental results were analyzed.
