The essencial objective of this paper is to point out the need for project evaluation with multiple criteria in the practice of complex systems decision making. The paper therefore starts showing how necessary a multiple criteria approach to project evaluation can be. A connection is then established between decision making processes and complex system planning. Basic models for plan ning complex systems are discussed and linked to the multiple criteria approach to project evaluation. The paper closes with a synthesis of the main advantages and eventual problems related to making use of multiple criteria approaches in the practice of systems planning.
