In today’s business many companies have a complex distribution network with several national and regional distribution centers. In this paper, we study an integrated facility location and inventory allocation problem for designing a distribution network with multiple national distribution centers (NDCs) and retailers. The key decisions are where to locate the regional distribution centers (RDCs...

Each distribution center has a different solution to prepare itself for incoming trucks. Due to different circumstances trucks can arrive earlier or later than anticipated. It is very hard, or maybe even impossible, for distribution centers to predict the actual truck arrival times, when they don’t know anything about the schedules from incoming trucks. A solution for these distribution centers...

Iran is located in an area with high earthquake risk. There are over 20 active faults with length of 500 km and also densely populated parts of the country have been rendered vulnerable to strong earthquakes. However, existence of eight faults of the main faults of Iran along with at least 18 faults with length of more than 100 km in Kerman province have turned the place into one of the riskies...

This paper proposes a modified non-dominated sorting genetic algorithm (NSGA-II) for a bi-objective location-allocation model. The purpose is to define the best places and capacity of the distribution centers as well as to allocate consumers, in such a way that uncertain consumers demands are satisfied. The objectives of the mixed-integer non-linear programming (MINLP) model are to (1) minimize...

In this technical report, we study the multiple-sink fixed-charge transportation problem (MSFCTP), which arises frequently in application areas of scheduling and cost control, such as facility planning, capital budgeting, resource allocation, buffer allocation, pollution control, etc. The MSFCTP problem involves the distribution from a set of supply centers (sources) to a set of demand centers ...

This paper presents a novel application of operations research to support decision making in blood distribution management. The rapid and dynamic increasing demand, criticality of the product, storage, handling, and distribution requirements, and the different geographical locations of hospitals and medical centers have made blood distribution a complex and important problem. In this study, a r...

September 30, 1994 ABSTRACT This paper addresses the problem of constructing multicast trees with reservation of resources. The main features of the approach described are that it tolerates asymmetric traffic loads on network links and algorithmically locates data distribution centers for every multiparticipant interaction. A fast and scalable algorithm for locating distribution centers based o...

An improved theory for remote-charge-scattering-limited mobility in silicon inversion layers is developed. The model takes into account the effects of image charges, screening, inversion layer quantization, the contribution of different subbands, oxide thickness, the actual distribution of charged centers inside the structure, the actual distribution of carriers in the inversion layer, the corr...
