A Humanitarian Logistics Model Considering Network Failure and Standard Relief Time with Split-Delivery

Supply chains have learned that as they work more integrated, they also help their profits. In this context,this paper analyzes a multi-depot location-routing model with consideration of network failure by uses of vehicles and standard relief time. The proposed model allocates locations of local depots and routing for last-mile distribution just after an earthquake. The model is divided by the two-part stochastic program with travel time which obeys uniform distribution and we deliberate on split-delivery. To clarify the method impact, some small cases have been solved by the use of GAMS software. And finally, a variable neighborhood search algorithm is proposed to solve the deterministic model. Our analytically proven results demonstrate the desirable results.
