This paper treats the problem of setting the inventory level of closed-loop flow lines operating under the constant-work-in-process (CONWIP) protocol. We solve a huge but simple linear program that models an entire simulation run of a closed-loop flow line in discrete time to determine a...

firm productivity and export decision are closely related to its innovation ac- tivity. Product innovation may play a more important role in the decision to start exporting, while the decision for process innovation may be triggered by success- ful exporting. This suggests that the causality...

We present a stochastic version of the single-level, multi-product dynamic lotsizing problem subject to a capacity constraint. A production schedule has to be determined for random demand so that expected costs are minimized and a constraint based on a new backlog-oriented -service-level measure...
