Decision support model for ranking project network activities based on multiple criteria of precedence, duration and cost

This paper proposes a decision support model for ranking project network activities and classifying those activities into groups. The model is based on multiple criteria (indexes) that derived from the precedence, duration and cost of the activities. The uniqueness of the model is that the weights of the ranking criteria of the project activities are objectively evaluated by applying data envelopment analysis (DEA) methodology. The model is applicable to any type of project. An illustrative example demonstrates the applicability of the model. The proposed model can help project managers allot their managerial efforts and care to the most important activities.
