Dynamic assignation of due-dates in an assembly shop based in simulation

Abstract

This article addresses the problem of reducing the tardiness and percentage of delayed jobs through a combination of the dispatch rule and assignation of due dates. The consideration of the time needed for jobs in the shop facilitates the organisation of the materials and resources and the fulfilment of the due dates, and it also allows the jobs that have to be urgently processed to be identified. The aim of this article is to present a rule for the assignation of due dates based on simulation. A procedure to insert idle time, which controls the progress of the jobs that may not be completed on time, is also proposed.
