This research study presents a comprehensive model for selection of decisive criteria to develop and integrate a fourth-party logistics concept in humanitarian logistics sector. The model is based on applying an analytic network process for determination of final criteria selection for a fourth-party logistics solution. The analytic network process is used to solve complex multiple qualitative ...

hub location-allocation problems are currently a subject of keen interest in the research community. however, when this issue is considered in practice, significant difficulties such as traffic, commodity transportation and telecommunication tend to be overlooked. in this paper, a novel robust mathematical model for a p-hub covering problem, which tackles the intrinsic uncertainty of some param...

The hub location–allocation problem under uncertainty is a real-world task arising in the areas such as public and freight transportation and telecommunication systems. In many applications, the demand is considered as inexact because of the forecasting inaccuracies or human’s unpredictability. This study addresses the robust uncapacitated multiple allocation hub location problem with a set of ...

The increasing number of victims from disasters in recent years results in several challenges for authorities aiming to protect and provide support to affected people. Humanitarian logistics represents one of the most important fields during preparedness and response in cases of disaster, seeking to provide relief, information and services to disaster victims. However, on top of the challenges ...

We propose a framework to robust stochastic optimization model for disaster management planning; in particular, we address making integrated decisions about the distribution of relief supplies and evacuation operations. Our decision-making approach recommends the best relief distribution centers to use as storage locations and determines their optimal inventory levels. The model also incorporat...

When a disaster strikes an area, often international assistance is requested to help responding and recovering from the disaster. The response characterized by dispatch of relief items affected regions via depots Humanitarian Logistics Service Providers (HLSPs). One challenges HLSP faces how organize its network depots. Important questions are many should be opened what their locations be? We d...

Many portfolio optimization problems deal with allocation of assets which carry a relatively high market price. Therefore, it is necessary to determine the integer value of assets when we deal with portfolio optimization. In addition, one of the main concerns with most portfolio optimization is associated with the type of constraints considered in different models. In many cases, the resulted p...

The efficient design/redesign of the logistics network is essential for companies to maintain their competitive advantage. This paper presents a novel non-linear mixedinteger programming model for the multi-product capacitated location routing inventory problem (MPCLRIP), where a two-layer distribution system consisting of depots and customers was studied. The supply decisions such as location ...
