MixedModel Sequencing Problem with overload minimization considering workstations dependencies
Bautista Valhondo, Joaquín; Suárez Feijóo, Raúl
Proceedings of T2B.3 2009 IEEE International Symposium on Assembly and Manufacturing 1720 November 2009, Suwon, Korea 9781424446285/09/$25.00 ©2009 IEEE Mixedmodel sequencing problem with overload minimization considering workstations dependencies Joaqu ́ ın Bautista and Ra ́ ul Su ́ arez Abstract — This paper reviews the formulation of the Mixed Model Sequencing Problem with Workload minimization (MMSPW). Two significative models already presented in the literature are describe, showing that they are valid for the case of parallel workstations, but do not properly solve the case of serial workstations. After that, a new model is introduced that is valid for the case of serial workstations. An example is used to illustrate the performance of all the models, and a computational experience was done to verify the applicability of the proposed model using the solver CPLEX and a set of problem instances of small dimension adapted from the literature.

Simultaneous Interconnection and Damping Assignment PassivityBased Control: Two Practical Examples
Batlle Arnau, Carles; Dòria Cerezo, Arnau; Espinosa Pérez, Gerardo; Ortega, Romeo
Passivitybased control (PBC) is a generic name given to a family of controller design techniques that achieves system stabilization via the route of passivation, that is, rendering the closedloop system passive with a desired storage function (that usually qualifies as a Lyapunov function for the stability analysis.) 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.

SemiDynamic Demand in a NonPermutation Flowshop with Constrained Resequencing Buffers.
Färber, Gerrit Hartmut; Salhi, Said; Coves Moreno, Anna Maria
This work presents the performance comparison of two conceptually different approaches for a mixed model nonpermutation flowshop production line. The demand is a semidynamic 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.
