Özet
In this paper, we consider a hybrid production system with two distinct production lines, where one of them undertakes remanufacturing activities while the other executes traditional manufacturing tasks. The output of either production line can satisfy the demand for the same type of product without any penalties. The realization times for demand occurrences and service completions are random. In order to control such production systems, we propose a single-stage pull type control mechanism with adaptive kanbans and state-independent routing of demand information. The mechanism is modeled as a stochastic queueing network and performance measures are obtained for stationary behavior. Alternative static control policies are compared with the proposed policy with respect to an expected total cost function of these performance measures. An experimental design of L(2137) covering low to high traffic densities is utilized for the numerical analysis. The numerical comparison shows that on the average, the adaptive kanban control mechanism in consideration performs 20 % better than the best static kanban control mechanism.
