Multi actor multi criteria analysis (MAMCA) as a tool to support sustainable decisions: State of use

In this contribution, the multi actor multi criteria analysis (MAMCA) to evaluate transport projects is presented. This evaluation methodology specifically focuses on the inclusion of the different actors that are involved in a project, the so-called stakeholders. Like the traditional multi criteria decision analysis (MCDA), it allows including qualitative as well as quantitative criteria with their relative importance, but within the MAMCA they represent the goals and objectives of the multiple stakeholders. As such, the stakeholders are incorporated in the decision process. The theoretical foundation of the MAMCA method is shown, together with several applications in the field of transport appraisal.

► Stakeholder involvement is indispensable in the evaluation of transport projects.
► A MAMCA explicitly uses the objectives of the stakeholders in the evaluation process.
► The MAMCA is able to tackle social complex decision problems.
► The theoretical foundation of the MAMCA is shown, with its several applications.
► Possible issues that can be encountered within the decision process are highlighted.
