An exact algorithm for project scheduling with resource constraints based on a new mathematical formulation

ABSTRACT
In this paper we consider the Project Scheduling Problem with resource constraints, where the objective is to minimize the project makespan. We present a new 0-1 linear programming formulation of the problem that requires an exponential number of variables, corresponding to all feasible subsets of activities that can be simultaneously executed without violating resource or precedence constraints. Different relaxations of the above formulation are used to derive three new lower bounds, which dominate the value of the longest path on the precedence graph and are tighter than bound proposed by Stinson et al. (1978). A tree search algorithm based on the above formulation, that uses lower bounds and dominance criteria is also presented. Computational results indicate that the exact algorithm can solve hard instances that cannot be solved by the best algorithms reported in the literature.
