Joint Optimization of Production Lot Sizing and Preventive Maintenance Threshold Based on Nonlinear Degradation

In a manufacturing system, lot sizing and maintenance are interdependent interact with each other. Few studies jointly investigated production management considering system degradation. However, during the process, critical component performance will undergo inevitable degradation over time. For example, equipment wears out due to both its own internal causes external environment. To monitor interval inspection is usually performed obtain information about nonlinear more general. Thus, based on of this study developed joint optimization model preventive (PM) thresholds goal maximizing profit per unit The decision follows control limit principle, i.e., choice between (PM), corrective (CM), or neither (do nothing) magnitude A simulation algorithm proposed optimal lot-sizing allocation PM thresholds. effectiveness illustrated by numerical examples results show that maximum time can be obtained reasonably formulating sizing.
