Facility location-allocation models are used in a widespread variety of applications to determine the number of required facility along with the relevant allocation process. In this paper, a new mathematical model for the capacitated multi-facility location-allocation problem with probabilistic customer's locations and fuzzy customer’s demands under the Hurwicz criterion is proposed. Thi...

The quality of database distribution design, which involves fragmentation and allocation, should be assessed by the performance of a system. In particular, this applies to non-relational database systems. This paper addresses fragmentation and allocation in the context of complex value databases. Fragmentation and fragment allocation are performed simultaneously. For this we present a query pro...

Cloud computing is considered to be a new service provider technology for users and businesses. However, the cloud environment is facing a number of challenges. Resource allocation in a way that is optimum for users and cloud providers is difficult because of lack of data sharing between them. On the other hand, job scheduling is a basic issue and at the same time a big challenge in reaching hi...

We propose to allocate the cost of a minimum spanning tree by defining claims problem and using rules, then providing easy intuitive ways distribute this cost. Depending on starting point that we consider, define two models. On one hand, benefit-sharing model considers individuals’ costs source as point, benefit building efficient is shared agents. other costs-sharing starts from connection (th...

A freight forwarder may consolidate its goods transportations in order to achieve a more efficient operation. When goods transportations are consolidated, they may reduce operational costs, e.g. labor and fuel. This can be further improved if a number of freight forwarders cooperate and consolidate their collective goods transportations, i.e. it is a cooperation between competitors, a coopetiti...

A cooperative game in partition function form is proposed for a cost allocation problem. The game describes a real situation in which a payoff of any coalition does not only depend on the players in the coalition but also on the coalition structure of the other players. Solution concepts like the stable set and the core are analyzed. Relations of the concepts in the case of the game in partitio...

Suppose that a group of agents have demands for some good. Each one of them owns a technology allowing to produce the good, with these technologies varying in their effectiveness. We consider technologies exhibiting either increasing return to scale (IRS) or decreasing returns to scale (DRS). In each case, we solve the issue of the effi cient allocation of the production between the agents. In ...

For firms remanufacturing their products, the total life-cycle costs and revenues from new and remanufactured products determine their profitability. In many firms, manufacturing/sales and remanufacturing/remarketing operations are carried out in different divisions. Each division is responsible for only part of the product’s life cycle. Practices regarding transfer pricing across divisions var...
