The problem of maximal hub covering as a challenging problem in operation research. Transportation programming seeks to find an optimal location of a set of hubs to reach maximum flow in a network. Since the main structure's parameters of the problem such as origin-destination flows, costs and travel time, change periodically in the real world applications, new issues arise in handling it. In t...

The location planning of emergency medical service (EMS) stations is crucial, especially in populated cities with heavy traffic conditions like Istanbul. In this paper, we propose both a single-period and a multi-period problem, two variants of the well-known Maximal Covering Location Problem, which require two types of services in the location planning of the EMS stations. The objective of the...

In this paper, a new multi-objective integer non-linear programming model is developed for designing citrus three-echelon supply chain network.
