Production Control of Remanufacturing Systems with General Repair Time Distributions
We consider the control of a manufacturing system executing capital assets repair and remanufacturing in a closed-loop system. It is assumed that the production system responds to planned demand at the end of the expected life of each individual piece of equipment and unplanned demand triggered by equipment failures. The difficulty of controlling this type of production system resides in the variable nature of the remanufacturing process. In practice, remanufacturing operations for planned demand can be executed at different rates, referring to different component replacement and repair strategies. A sub-optimal control policy described by inventory thresholds triggering the use of different execution modes has already been formulated in previous research to address this problem when unplanned demands are processed under exponential time distribution. The aim of this study is to extend this control policy to more realistic processing time distributions. Our simulation results demonstrate that the proposed control approach can also be applicable to a wide variety of complex remanufacturing problems where analytical solutions may not be easily obtained.
