Resource Constrained Project Scheduling Models under Random Disturbances
extremely costly resources (A-resources) which have to be obtained for a short time within the project’s time span. Such resources have to be prepared and delivered externally at planned moments,
renewable resources (B-resources) which are at the company’s disposal.
the earliest starting moment for each project’s realization,
the limited resource levels for each type of resources to be stored during the projects’ realization,
the moments when resources are fed in and projects’ activities start,
to predetermine in advance, i.e., before each project starts to be realized, a deterministic delivery schedule for A-resources which are not at the project’s disposal,
to determine both the starting times and the resource capacities to be utilized for activities which require limited renewable B-resources which are at the project’s disposal,
to determine the starting moment of each project’s realization,
Problems of resource project scheduling are solved via simulation, in combination with a cyclic coordinate descent method and a knapsack resource reallocation model.
KeywordsResource constrained project scheduling Cyclic coordinate descent method Resource reallocation Resource delivery schedule Non-consumable resources
