Reactive scheduling in a make-to-order flexible job shop with re-entrant proces...
Gomes, Marta C.; Barbosa-Póvoa, Ana Paula; Novais, Augusto Q.A mixed-integer linear programming model is presented for the scheduling of flexible job shops, a production mode characteristic of make-to-order industries. Re-entrant process (multiple visits to the same machine group) and a final assembly stage are simultaneously considered in the model. The formulation uses a continuous time representation and optimises an objective function that is a weighted sum of order ...
Scheduling of job shop, make-to-order industries with recirculation and assembl...
Gomes, Marta C.; Barbosa-Póvoa, Ana Paula; Novais, Augusto Q.This work studies the performance of two Mixed Integer Linear Programming (MILP) models to solve scheduling problems in a flexible job shop environment with recirculation and assembly using a due-date-based objective function. The models convey different approaches both in the modelling of time (discrete and continuous approaches) as well as in the assignment of jobs to machines. The comparison is carried out f...
