Optimal control policy for combined production–maintenance and multivariate quality monitoring of an imperfect manufacturing system with replenishment and assignable causes

Key Points

• Optimal control policy improves multivariate quality monitoring and production maintenance in manufacturing systems.
• A significant metric is the reduction of defects by 30% over a 12-month period in quality control.
• Analysis of production and maintenance records provides insight into system performance and inefficiencies.
• Implications support enhanced operational protocols, with potential benefits for minimizing costs and downtime.
