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...

background although liver transplantation is the last resort for treating end stage liver diseases, this medical procedure is not available for all needful patients because of inadequate organ supply. therefore, guidelines have been developed by medical experts to regulate the process. some professionals believe that medical criteria are inadequate for organ allocation in all situations and may...

the distribution of extracellular enzyme activities in particle-size fractions of sediments was investigated in a subtropical mangrove ecosystem. five enzymes involved in carbon (c), nitrogen (n), and phosphorus (p) cycling were analyzed in the sand, silt, and clay of sediments. among these fractions, the highest activities of phenol oxidase (pho), β-d glucosidase (glu), and n-acetyl-glucosimin...

distribution and allocation of resources is affected by factors such as values, norms, social stratifications, ideology, information, coercion, political challenges, and even external factors. this finding means that there is always a fundamental tendency to redirect resources toward political goals instead of public interests and development. because the resource structure is strongly influenc...

Cloud computing is a model that provides services through internet to its users. It enables users to put their data and services on the internet and same can access through internet. The most challenging task of cloud computing is resource allocation. In this paper, challenges of cloud computing are addressed in which resource allocation is one of the main challenges. Resource allocation and it...

In this report, an integrated system approach to dynamic resource allocation is proposed. Some of the problems in dynamic resource allocation and the relationship of these problems to system structures are examined. A general dynamic resource allocation scheme is presented. A hierarchical system architecture which dynamically maps between processor structure and programs at multiple levels of i...

In this paper we expand on our previous efforts [1,2,3] to evaluate strategies for improving tracking performance of a multi-sensor surveillance system. The quality of tracking performance is based on two measures: (i) The Mean Track Quality (MTM) and (ii) Total Expected Number of Misses (TEM). Five strategies of resource allocation were considered based on (a) local versus coordinated, (b) ded...

Business Process Management Systems (BPMS) is a complex information system that provides designing, administrating, and improving the business processes. Task allocation to human resources is one of the most important issues which should be managed more efficiently in BPMS. Task allocation algorithms are defined in order to meet the various policies of organizations. The most important of these...
