یک مدل انتخاب چند سیستم معیوب برای سیستم چند منظوره: مطالعه موردی سیستم فیدر بانکوک

Selection of transit systems is one of the most complicated decisions as it concerns several decision factors and stakeholders. Governments’ objectives are to maximize overall social, economic and environmental benefits including connectivity and mobility enhancement, transport service equality, economic revitalization, and environmental restoration but to minimize all possible conflicts. Designers and developers’ objectives are to minimize construction time but to maximize network expansion opportunities. Financial institutes’ objectives is to minimize the investment costs including capital and operating costs. Communities’ objectives are to minimize environment impacts, traffic impact, land acquisition, and loss of revenues on the local transport modes but to maximize road users’ safety. Transit users and operators’ objective is to maximize riding comfort, mobility and accessibility. Each stakeholder's objectives are usually conflicting with the others’. To avoid and resolve such conflicts, governments or policy makers need a decision tool to help them make a transit choice that not only satisfies but also balances all stakeholders’ needs. This research study introduces a transit system selection model that is developed on the multi-attribute utility theory (MAUT) to normalize the score of the alternative in each decision factor and criteria and the rank-order centroid (ROC) theory to allocate weights to each decision factor and criteria. Finally, the final decision is suggested by the proposed multi-actor multi-criteria decision model. A decision to Bangkok feeder system choice is considered as a case study.
