A multistage scenario optimisation procedure to plan annualised working hours under demand uncertainty.
(Elsevier, 2008-06)
Article
Open AccessThe annualisation of working hours (i.e., the irregular distribution of the total number of working hours over the course of a year) makes it possible to adapt production capacity to fluctuations in demand. The required ... -
An algorithm for a biobjective parallel machine problem with eligibility and release and delivery times
(2012)
Conference report
Restricted access - publisher's policyThe scheduling of parallel machines is a well-known problem in many companies. Nevertheless, not always all the jobs can be manufactured in any machine and the eligibility appears. Based on a real-life situation, we present ... -
