In this research, a tri-objective mathematical model is proposed for the Transportation-Location-Routing problem. The model considers a three-echelon supply chain and aims to minimize total costs, maximize the minimum reliability of the traveled routes and establish a well-balanced set of routes. In order to solve the proposed model, four metaheuristic algorithms, including Multi-Objective Gre...

This paper assumes that the demand is a Poisson random process, the inventory strategy is (s, S), each demand amount Q* is same, scale of the economic transport quantity Q0=p Q* (p is a positive integer), in which Q* is the optimal order quantity of joint pricing used by the supplier and retailer, and the supplier will be entitled to ignore small group of temporary order bills to accumulate the...

Hazardous Materials transportation risk mitigation may be achieved by reducing the accident probability and alleviating the associated potential consequences. The consideration of risk as a criterion for selecting Hazardous Materials distribution routes contributes substantially to the reduction of accident probability and the severity of the accident consequences. Furthermore the optimum deplo...

The inventory routing problem presented in this study is a one-to-many distribution network consisting of a manufacturer that produces multi products to be transported to many geographically dispersed customers. We consider a finite horizon where a fleet of capacitated homogeneous vehicles, housed at a depot/warehouse, transports products from the warehouse to meet the demand specified by the c...

Distribution network design (DND) attempts to integrate tactical issues such as inventory policies and/or vehicle routing decisions with strategic ones such as the problem of locating facilities and allocate customers to such facilities. When inventory policy decision making is considered the problem is also known as inventory location modelling (ILM) problem. During the last two decades, mathe...

Facility location, inventory control, and vehicle routes scheduling are critical and highly related problems in the design of logistics system for e-business. Meanwhile, the return ratio in Internet sales was significantly higher than in the traditional business. Many of returned merchandise have no quality defects, which can reenter sales channels just after a simple repackaging process. Focus...

This study considers a reliable location – inventory problem for a supply chain system comprising one supplier, multiple distribution centers (DCs), and multiple retailers in which we determine DCs location, inventory replenishment decisions and assignment retailers to DCs, simultaneously. Each DC is managed through a continuous review (S, Q) inventory policy. For tackling real world conditions...

Traditional inventory routing problems ignore the time consumption in transportation. In this paper, an problem with air–land transportation and route-dependent lead times is studied. The model based on rolling horizon framework which can serve as a “here-and-now” approximation for multi-period problems. A planning crossing strategy proposed to consider effect of single-period decision long-ter...
