A multi-objective approach for decision making during the project life cycle

This paper is concerned with the multi-objective nature of projects and proposes a comprehensive methodology for the decision making process during the project life cycle. We address a situation in which several decisions are considered, where each may affect the major project objectives: time, cost and scope. The objectives are formally defined and a multi-objective, mixed-integer, linear-programming formulation for the decision selection is developed. We then provide the decision maker with a set of non-dominated alternatives, each associated with a subset of the feasible decisions.
