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...

This paper presents branch-and-bound parallelization strategies applied to the location/ allocation problem with balancing requirements. This formulation is representative of a larger class of discrete network design and location problems arising in many transportation logistics and telecommunications applications: it displays a multicommodity network ̄ow structure and a complex objective funct...

Assigning facilities to locations is one of the important problems, which significantly is influence in transportation cost reduction. In this study, we solve quadratic assignment problem (QAP), using a meta-heuristic algorithm with deterministic tasks and equality in facilities and location number. It should be noted that any facility must be assign to only one location. In this paper, first o...

objectives: the needs and problems of students with physical-motor disabilities should be properly identified in order to solve them. the main purpose of this research was to determine the needs and problems of iranian male students with physical-motor disabilities in the education and employment dimensions.  methods: this was a descriptive study. all the male students with physical-motor disab...

Abstract A network of queueing-inventory systems is considered where the inventories are replenished by a common central server. Travel times for transport items send out from center and an adaptive dispatching regime to direct transportation towards locations with incorporated in model. The stationary distribution system product form explicitly given. An optimization procedure developed find g...

the location-routing problem is a relatively new branch of logistics system. its objective is to determine a suitable location for constructing distribution warehouses and proper transportation routing from warehouse to the customer. in this study, the location-routing problem is investigated with considering fuzzy servicing time window for each customer. another important issue in this regard ...
