To reduce the logistic cost and carbon emission improve customer satisfaction, this study proposes a multiobjective green time-dependent location routing problem (MOGTDLRP) model in which objectives are to minimize distribution total cost, delivery time, fuel consumption. This will be solved by several hyperheuristic algorithms include high-level heuristics low-level heuristics. There three acc...

This study extends a mathematical model that integrates the location, allocation, inventory replenishment and routing decisions simultaneously. To cope with inherent uncertainty of parameters, we implement a continuous-time Markov process and derive the performance measures of the system. Using the obtained results, the problem is formulated as a mixed integer nonlinear programing model (MINLP)...

in the case of hazardous materials management, selected routes for carrying hazardous materials (i.e.,hazmat) have significant effects on locating hazmat distribution centers. since, risk and cost are usuallyconsidered as two main attributes to determine the best routes, optimized locations are sequentially outlineddepending on selected routes. in the present paper, two different approaches of ...

Compared with topology -based routing, location-based routing scales much better in large-scale mobile ad hoc networks. Location-based routing protocols assume that a location service is available to provide location information of each node in the network. Many location service protocols have been proposed in the literature. However, either they do not scale well in large-scale network environ...
