Multi Entity Perspective Transportation Infrastructure Investment Decision Making
نویسندگان
چکیده
Investment in new large transportation infrastructure is capital-intensive and irreversible in nature. Private sector participation in infrastructure investment has gained popularity in recent times because of scarcity of resources at the public sector, and because of the ability of the private sector to build, operate, maintain such facilities, and share future uncertainties. In such cases, there are multiple entities each with different objectives in the project. The analytic techniques used to determine feasibility of such projects are often deterministic and do not consider two critical elements. First, the need to identify major entities involved in these projects and their individual objectives; second, the importance of analyzing measures of effectiveness of each entity in a multi objective context. A framework is proposed in this paper to address these issues. Also, a set of relaxation policies is proposed to reflect the nature and level of participation of the entities. First, the feasibility of each single entity perspective is determined and next, a multi-objective optimization (MOO) is proposed reflecting the perspectives of all entities. The MOO results in pareto optimal solutions to serve as tradeoff between the participation levels of the multiple entities. Analytic Hierarchy Process (AHP) is used as a tool to narrow down number of options for decision makers for further consideration. AHP and MOO are integrated to determine the feasibility of strategies from multi entity Corresponding author.: Tel.: +1 301 405 9424, fax.: +1 301 314 5639 E-mail address: [email protected] (Sabyasachee Mishra), [email protected] (Snehamay Khasnabis), [email protected] (Subrat Swain)

Multi-perspective Decision Support System for Hierarchical Bus Transportation Network Design: Tehran Case Study
In this paper, a multi-perspective decision support system (MP-DSS) to design hierarchical public transportation network is developed. Since this problem depends on different perspectives, MP-DSS consists of two sub-systems with macro and micro sub-systems based on travel information, land use and expert knowledge. In the micro sub-system, two sub-modules are developed considering o...
