Scheduling model for a building renovation project with re-add and storage of resource types under supplier limited production capacity
Résumé
Resource constrained project scheduling problem, RCPSP, in its basic form consists in minimizing total makespan of effectuating a group of activities subject to precedence constraints and resource availability limitations. In this paper, we deal with a new extension of RCPSP’s mathematical model. Our work which proposes an optimisation model for a French project of buildings’ thermal renovation overcomes existing gap of RCPSPs by either considering the recharge for renewable resources from an external subcontractor or heeding capacity limitations for production and storage of non-renewable resources in problem modelling. The mathematical model aims to minimize total cost of the system implementation that includes recharge cost of non-renewable resources, execution cost of the activities, stock cost of non-renewable resources and rent cost of expensive required equipment through the execution period of the project. In order to obtain the outputs of the model, a solution methodology based on linear programming relaxation has been proposed and applied on the proposed mathematical model. The suggested procedure reduces number of integer variables by defining the bounds for earliest and latest start time of the project.
