A mathematical model and optimization of total production cost and quality for a deteriorating production process


Proper production planning can considerably improve a producer’s competitiveness in delivering low-cost products with high quality and short-cycle time. In a deterioration process, the quality may change during a production run, leading to early product failures. To mitigate the impact of deterioration such as process shifting, the optimal resetting cycle before the next setup must be determined, as well as the initial settings at the beginning of a production run. The aim of this study is to propose a mathematical model that consists of a new quality loss function and adds maintenance costs to the ordering and inventory holding costs commonly considered in the classical model. The model is applied to a real-world case study to demonstrate the effect of initial settings of the mean quality characteristic. The results demonstrate the superiority of the proposed approach in terms of total production cost, as compared with the economic production quantity model. *Corresponding author: Mohammad Hossein Zavvar Sabegh, Faculty of Engineering, Department of Industrial Engineering, Kharazmi University, Moffateh Ave, Tehran 1571914911, Iran E-mail: mzavvar80@gmail.com Reviewing editor: Xiao-Jun Yang, China university of Mining and Technology, China Additional information is available at the end of the article ABOUT THE AUTHORS Mohammad Hossein Zavvar Sabegh is currently an associate member at American Society for Quality (ASQ).

PUBLIC INTEREST STATEMENT Recently, the integration of production, maintenance, and quality control has attracted much attention. The deteriorating process and their maintenance have a great importance in reliability engineering. The paper proposed a new economic production quantity model to consider the production cycle time and quality characteristic to minimize total expected production cost that consists of quality loss and maintenance costs. We used the model to calculate total production cost in a spring production line in Iran. To investigate the initial effect of the mean quality characteristic, the computational analysis on a real world has been applied. The results illustrate the total production cost has been reduced from the proposed approach compared with the traditional economic production quantity model.
