In this study, a two echelons supply chain system in which a supplier is producing perishable product and distribute it to multiple customers is considered. By allowing lateral transshipment mechanism, it is also possible to deliver products to some customers in some periods in bulk, then customers using their own vehicle to transship goods between each other seeking further reduction in the ov...

<p style='text-indent:20px;'>A combined location-routing-inventory system (CLRIS) in a three-echelon supply chain network is studied with environmental considerations. Specifically, bi-objective mixed integer programming model formulated for the CLRIS to deal trade-offs between total cost and carbon-capped difference (CCD). A multi-objective particle swarm optimization (MOPSO) heuristic s...

In this article, we propose a special case of two-echelon location-routing problem (2E-LRP) in cash-in-transit (CIT) sector. To tackle this realistic problem and to make the model applicable, a rich LRP considering several existing real-life variants and characteristics named BO-2E-PCLRPSD-TW including different objective functions, multiple echelons, multiple periods, capacitated vehicles, dis...

centralizing and using proper transportation facilities cut down costs and traffic. hub facilities concentrate on flows to cause economic advantage of scale and multimodal transportation helps use the advantage of another transporter. a distinctive feature of this paper is proposing a new mathematical formulation for a three-stage p-hub location routing problem with simultaneous pick-ups and de...

This study introduces a general framework, called Bi-sided facility location, for wide range of problems in the area combined location and routing such as locating test centres designing network supermarkets. It is based on multi-objective optimisation model to enhance service quality which clients received, client-side, interconnection eligibility among centres, center-side. Well-known k-media...

In this paper, we introduce the Steiner Bi-objective Shortest Path Problem. This problem is defined on a directed graph G=(V,A), with subset T?V of terminals. Arcs are labeled travel time and cost. The goal to find complete set efficient paths between every pair nodes in T. motivation behind stems from data preprocessing for vehicle routing problems. We propose solution method based labeling ap...

increasing of the distribution efficiency is one of the most objectives of an integrated logistic system developed as a new management philosophy in the past few decades. the problem is examind in two parts: facilities location problem (flp) for long policies and vehicle routing problem (vrp) to meet the customer demand. these two components can be solved separately; however, this solution may ...

A great loss of transportation capacity has been caused in auto parts supply logistics due to the independent from suppliers (APSs) automobile production line (APL). It is believed that establishing distribution centers (DCs) for centralized collection and unified one effective way address this problem. This paper proposes a framework simultaneously considering location-inventory-routing proble...

Taking into account the variety of real-world constraints and incorporating them classical problems are essential in designing supply chain networks. Meanwhile, given importance outsourcing, open location-routing problem (OLRP) is proposed to fulfill customers' demands minimize costs by determining optimal location vehicle facilities routes. In addition, sustainability attracting increasing att...
