Resource-constrained scheduling with non-constant capacity and non-regular activities

Giorgio Fasano(giorgio.fasano***at***thalesaleniaspace.com)

Abstract: This work is inspired by very challenging issues arising in space logistics. The problem of scheduling a number of activities, in a given time elapse, optimizing the resource exploitation is discussed. The available resources are not constant, as well as the request, relative to each job. The mathematical aspects are illustrated, providing a time-indexed MILP model. The case of a single resource is analysed first. Extensions, including the multi-resource case and the presence of additional conditions are considered. Possible applications are suggested and an in-depth experimental analysis is reported.

Keywords: resource constrained project scheduling problem (RCPSP), non-constant resource capacity, non-constant resource request, irregular job/activity/cycle profile, multi-resource, time-indexed scheduling, mixed integer linear programming (MILP), global optimization (GO)
