A fuzzy-set analysis of regional transportation projects

The paper offers an approach to support decision-making on selecting an investment project among alternative large-scaled transportation projects. This approach is based on principles of fuzzy set theory. Using this approach, we analyze the competitive projects on construction a bridge connecting the Russky Island. For this purpose we calculate and analyze the costs of alternative projects and their planned timing schedules. We present a cost- risk assessment of a set of timing schedules admissible within network constraints to compute a fussy set of Paretto-optimal plans. We also present our recommendations on how any timing schedule could be corrected.
