Abstract: Abstract Since all production processes are not perfect, all products produced by a company may not meet the quality standards desired by its customers. Moreover, equipment breakdowns and failures during the production cycle can delay the production process. Consequently, it is necessary to integrate statistical process monitoring and maintenance decisions in conjunction with inventory control. Additionally, to remain competitive and maintain market share, successful manufacturers should be able to offer warranty services for their products, which impose additional costs during the post-sale period of the product. The goal of this study is to minimize the total costs incurred in both the pre-sale and the post-sale periods. To that end, an integrated model of inventory control, maintenance scheduling, and statistical process monitoring is proposed for products sold under the free minimal repair warranty policy. Three comparative analyses are conducted to evaluate the impact of incorporating warranty, accounting for process failure and statistical process monitoring as part of the model.
