Quality is becoming a business strategy leading to success, growth, and enhanced competitive position. Organizations with successful quality improvement programs can enjoy significant competitive advantages. With increasing automation and mechanization, production processes are shifting from workers to machines. Consequently, the role of equipment maintenance in controlling quantity, quality and costs are more evident and important than ever. To succeed in this new environment, equipment must be maintained in ideal operating conditions and must run effectively. This paper summarizes an overview of integrating statistical process control and maintenance by jointly optimizing their policies to minimize the total costs associated with quality, maintenance, and inspection. Based on the review of some typical new approaches and methods that were introduced, the advantages and disadvantages of these methodologies were discussed. Finally, a review of the literature, there has been some increased trends in the area of integrated research on maintenance and quality control.
