Setting inventory levels of CONWIP flow lines via linear programming

Helber, Stefan; Schimmelpfeng, Katja; Stolletz, Raik - Wirtschaftswissenschaftliche Fakultät, Leibniz … - 2009

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...

Stochastic lot sizing problem with controllable processing times

Koca, Esra; Yaman, Hande; Selim Aktürk, M. - In: Omega 53 (2015) C, pp. 1-10

In this study, we consider the stochastic capacitated lot sizing problem with controllable processing times where … processing times can be reduced in return for extra compression cost. We assume that the compression cost function is a convex … computational experiments show that taking the processing times as constant may lead to more costly production plans, and the value …
