Resource constrained scheduling within fixed project durations

This paper presents a practical approach for resource constrained scheduling within a given project duration. The method ensures a stable project plan when activity durations are reduced to achieve this. It handles all four categories of resource (unconstrained, renewable, non-renewable and doubly-constrained resources), and aims to shorten the project duration at minimum cost. Soft constraints and resource availabilities which vary over time are allowed in the method. Computational experience is reported.
