Traditional pavement maintenance, rehabilitation, and reconstruction (MRR) planning accounts for user cost by maximizing drivers’ comfort, reducing users’ travel delay, minimizing fuel consumption, while controlling the agency’s costs of undertaking necessary preservation activities. Safety performance is seldom considered in MRR pavements. However, condition has a large impact on crash frequen...

Fuzzy portfolio selection has resulted in many researchers to focus on this field. Based the risk attitudes, study discusses attitudes a decision group for selection. Therefore, we adopt describe experts’ preferences and subjective judgments, then suppose that seeker considers higher return an excess investment based selected guaranteed rate of return; averter shortage securities whose rates ar...

According to the characteristics of emergencies, a dynamic multi-objective emergency decisionmaking model is proposed. By introducing triangular fuzzy Numbers calculate correlation distance between selected solution, ideal solution and negative considering degree solutions, indexes highlighted. In addition, paper strengthens processing uncertain information in real world through comprehensive i...

In this paper, a Multi-Choice Stochastic Bi-Level Programming Problem (MCSBLPP) is considered where all the parameters of constraints are followed by normal distribution. The cost coefficients of the objective functions are multi-choice types. At first, all the probabilistic constraints are transformed into deterministic constraints using stochastic programming approach. Further, a general tran...

This work introduces the following concepts of directional and estimated Pareto front to encourage multi-objective decision making, especially when exists in limited regions objective space. The general output optimization is a set non-dominated solutions approximate front. When regions, few are obtained presented maker. representing value trade-off barrier making. introduced this study superse...

Power grid response against high-impact low-probability (HILP) events could be enhanced by (a) hardening mechanisms to boost its structural resilience and (b) corrective recovery mitigation analytics improve operational resilience. Planning for attempts find the optimal location of Tie switches in radially operated power distribution networks that enable harnessing network topology maximised HI...
