If the passivity property turns out to be output strict, with an output signal with respect to which the system is detectable, then asymptotic stability is ensured. 2009-12-14T09:03:05Z http://hdl.handle.net/2117/6072 Title: Semi-Dynamic Demand in a Non-Permutation Flowshop with Constrained Resequencing Buffers. Authors: Färber, Gerrit Hartmut; Salhi, Said; Coves Moreno, Anna Maria Abstract: This work presents the performance comparison of two conceptually different approaches for a mixed model non-permutation flowshop production line. The demand is a semi-dynamic demand with a fixed job sequence for the first station. Resequencing is permitted where stations have access to intermediate or centralized resequencing buffers. The access to the buffers is restricted by the number of available buffer places and the physical size of the products. An exact approach, using Constraint Logic Programming (CLP), and a heuristic approach, a Genetic Algorithm (GA), were applied. 2009-11-30T11:10:44Z
