摘要

The field of project scheduling has received a great deal of study for many years with a steady evolution of problem complexity and solution methodologies. As solution methodologies and technologies improve, increasingly complex, real-world problems are addressed, presenting researchers a continuing challenge to find ever more effective means for approaching project scheduling. This dissertation introduces a project scheduling problem which is applicable across a broad spectrum of real-world situations. The problem is based on the well-known Resource-Constrained Project Scheduling Problem, extended to include multiple modes, generalized precedence, and expediting resources. The problem is further extended to include multiple projects which have generalized precedence, renewable and nonrenewable resources, and expediting resources at the program level. The problem presented is one not previously addressed in the literature nor is it one to which the existing specialized project scheduling methodologies can be directly applied. This dissertation presents a decomposition approach for solving the problem, including algorithms for solving the decomposed subproblems and the master problem. This dissertation also describes a methodology for generating instances of the new problem, extending the way existing problem generators describe and construct network structures and this class of problem. The methodologies presented are demonstrated through extensive empirical testing.
