Collaborative decision-making in sustainable mobility: identifying possible consensuses in the multi-actor multi-criteria analysis based on inverse mixed-integer linear optimization

Abstract

Sustainability is a key word in modern transportation and logistics. It requires not only economic development but also environmental and social actions. The involvement of multiple stakeholders can express different perspectives and interests to achieve the balance between these three pillars. The multi-actor multi-criteria analysis (MAMCA) is a methodology that can include multiple stakeholders in the process of decision making. It is important in the field of transport and logistic project appraisal, as many projects fail to be implemented because of a lack of support from one or more stakeholders. In MAMCA, multiple stakeholders can use different criteria trees and express their own preferences. At the end of the analysis, the advantages and disadvantages of each of the proposed scenarios are highlighted. Possible consensuses are then being discussed. However, this last step often turns out to be a difficult task.The purpose of this paper is to propose a way to help the facilitator to identify this (these) consensus(es). This will be based on the use of a weight sensitivity analysis model that was recently developed in the context of the PROMETHEE methods and which is based on inverse mixed-integer linear optimization. This approach allows finding the minimum weight modification for each stakeholder in order to improve the position of a given alternative in the individual rankings and, in an ideal case, to the first position of all the rankings simultaneously. This approach is illustrated on two real MAMCA logistic project cases to seek sustainable mobility solutions.

Adopting Multiactor Multicriteria Analysis for the Evaluation of Energy Scenarios

“…Moreover, further research on sensitivity analysis's extent and form could determine the minimum modification of the criteria weightings for each stakeholder in order for all of them to reach consensus [80]. Here, the integration of mathematical optimisation methods into the MAMCA framework holds great potential [81]. Furthermore, the stakeholders' criteria weightings could be subject to uncertainties.…”

Sustainable Vacation Industry Mobility Criteria in Heritage Cultural Natural Conserved Areas

“…A method of decision-making in the transport sector that allows for increased stakeholder participation in the multi-actor multi-criteria analysis (MAMCA) [28], [34]- [38]. MAMCA involves stakeholders from the start of the decision process [39]. Stakeholders argue explicitly, and different points of view are underlined separately to see differences in the performance of alternatives [28].…”

The Complexity of Logistics Services at Transshipment Terminals

“…It is worth noting that nowadays, many services are performed under outsourcing agreements, and the appropriate decisions in this context should be taken into consideration [92]. Multicriteria analyses were also applied to solve transport and logistics issues [89,93,94]. The models presented in the previously mentioned publications are not applied to assess the service complexity of a transshipment terminal; however, they can become significant supports in terms of achieving such an objective.…”
