in our country, school bus routes are determined by experiments of driver without considering the scientific optimum route and location. traversing additional routes will always result an increase in vehicle movements and fuel consumption and enormous costs. hence, this paper will study the school bus routing in tehran considering special students and a model will be presented to minimize trave...

Cho, Hyejin. M.S.I.E., Purdue University, May 2016, The Casualty Transportation of Ebola Outbreak in Liberia: A Simulation Study. Major Professors: Seokcheon Lee and Yuehwern Yih. In this paper, we have solved the unique problem of casualty transportation problem under Ebola by developing dynamic policies for vehicle routing to provide practical decision support. The objective of the proposed m...

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...

In this paper, we study the distribution network design problem integrating transportation and infinite horizon multiechelon inventory cost function. We consider the trade-off between inventory cost, direct shipment cost, and facility location cost in such a system. The problem is to determine how many warehouses to set up, where to locate them, how to serve the retailers using these warehouses...

Under the trend of developing green transportation in China, tractor-and-trailer has received more attention. This paper focuses on network-type mode port hinterland, aiming to tackle problems low efficiency and customer satisfaction existing network. The authors recommend considering opening several alternative depots making vehicle scheduling decisions simultaneous order optimize Therefore, t...

The location-routing problem is the most significant and yet new research field in location problems that considers simultaneously vehicle routing problem features with original one for achieving high-quality integrated distribution systems in beside of the global optimum. Simultaneous pickup and delivery based on time windows are the two main characteristics of logistic management that have be...

In contrast to the classical location-allocation models, the location-routing problem (LRP) integrates vehicle routing and scheduling aspects in the location planning process. A survey and classification scheme of location-routing is e.g. proposed by [3] and [2]. This paper presents a LRP of a company which distributes finished cars. This LRP is decomposed into two steps. In the first step a se...
