This paper addresses the allocation and scheduling of relief teams as one main issues in response phase disaster management. In this study, a bi-objective mixed-integer programming (BOMIP) model is proposed to assign schedule disasters. The first objective function aims minimize sum weighted completion times incidents. second also minimizes tardiness operations. order be more similar real world...

In cities where the urban rail transit (URT) systems do not provide 24-h services, passengers may be able to reach their destinations if last train services have closed by time they arrive at transfer stations. This paper aims seek a well-coordinated timetable that can transport as many possible (referred reachable passengers) and also those who cannot unreachable stations close destinations. A...

This paper develops a bi-objective portfolio selection problem that maximizes returns and minimizes a risk measure called conditional Drawdown (CDD). The drawdown measures include the maximal Drawdown and Average Drawdown as its limiting case. The CDD family of risk functional is similar to conditional value at Risk (CVaR). In this paper, the fuzzy method has been used to solve the bi-objec...

the most important issues that should be considered in studying disaster management include temporary settlement of injured population, supplying relief commodities, designing an appropriate communication infrastructure for communication during disaster. for this purpose, in this paper a model has been proposed for locating shelters, warehouses of relief commodities, and also telecom towers, wh...
