in this paper, the competition between two supply chains and their elements is studied. each chain consisted of a manufacturer and a distributor and the two chains compete in a market with single type of customer sensitive to price and delivery time. therefore, this is a two-supply chain game and during the competition between two supply chains, elements of each supply chain (manufacturer and/o...

Cost efficiency measures the cost of resource by output production. While conventional cost efficiency models set targets separately for each DMU, There are cases where the Central decision making is seeking the above targets, and at the same tries to obtain the target of Min cost efficiency for the total consumption. in this paper we consider that there is a centralized decision maker (DM). In...

Most current schemes for multicast routing assume that multicast routers participate both in forwarding mul-ticast packets and in control algorithms for routing, resource reservation, and group management. By separating data and control ow, and by centralizing control in distinct control elements, we have designed a simple and scalable approach to IP multicast that we call Centralized Multicast...

The processing of k-NN queries has been studied extensively both in a centralized computing environment and in a structured P2P environment. However, the problem over an unstructured P2P system is not well studied despite of their popularity. Communication-efficient processing of k-NN queries in such an environment is a unique challenge due to the distribution, dynamics and large scale of the s...

Spanish Society of Hospital Pharmacy (SEFH) includes among its purposes and functions the promotion, fostering and furthering of the performance of all kinds of training programmes and scientific projects, together with research and innovation activities in the area of Hospital Pharmacy. These actions are directed both to their development as well as to their appropriate applications, with the ...

Due to the rapid development of VLSI technology, computing systems can be made much more distributed and to match the structures of the problems for various applications. Because the characteristics of distributed computing systems are significantly different from those of centralized computing systems, different a,pproaches are needed to effectively address t,he design issues related to the ch...

This paper addresses the mobile assignment problem in a multi-cell broadcast transmission seeking minimal total power consumption by considering both transmission and operational powers. While the large scale nature of the problem entails to find distributed solutions, game theory appears to be a natural tool. We propose a novel distributed algorithm based on group formation games, called the h...

A new motion planning framework is presented that enables multiple mobile robots with limited ranges of sensing and communication to maneuver and achieve goals safely in dynamic environments. The framework is applicable to both planetary rover and free-floating space robot applications. To combine the respective advantages of centralized and decentralized planning, this framework is based on th...
