Several modern operating systems are providing multimedia applications with guaranteed access to resources such as network, disk and CPU to enable them to meet Quality of Service (QoS) requirements. The key to efficient resource usage is in determination of minimum resource guarantees subject to the constraints of given application quality of service requirements. We present a measurement based...

This paper proposes a new resource allocation model which is based on data envelopment analysis (DEA) and concerns systems with several homogeneous units operating under supervision of a central unit. The previous studies in DEA literature deal with reallocating/allocating organizational resource to improve performance or maximize the total amount of outputs produced by individual units. In tho...

structural characteristics and spatial distribution of major farming systems in mountain environment of the iranian plateau as well as their developments in the past few decades have been studied by statistical analysis. using this new approach, towards the study of natural resource allocation methods in mountains of iran, the following resulted: land and resource use practices have followed a ...

Given multiple products with unique lumpy demand patterns, this paper explores the determination of both the lot size for each product and the resource allocation among the products, given an investment budget for production rate improvements. Each product’s optimal production policy takes on only one of two forms: either continuous production or lot-for-lot production. A heuristic procedure de...

This paper investigates the centralized resource allocation with centralized structures by using the data envelopment analysis-ratio (DEA-R) models. To this end, it proposes a method to determine the resource allocation of centralized structures such that the ratio of inputs to outputs are minimized.

Studies of sex allocation offer excellent opportunities for examining the constraints and limits on adaptation. A major topic of debate within this field concerns the extent to which the ability of individuals to adaptively manipulate their offspring sex ratio is determined by constraints such as the method of sex determination. We address this problem by comparing the extent of sex-ratio adjus...

since software systems play an important role in applications more than ever, the security has become one of the most important indicators of softwares.cloud computing refers to services that run in a distributed network and are accessible through common internet protocols. presenting a proper scheduling method can lead to efficiency of resources by decreasing response time and costs. this rese...

data envelopment analysis (dea) is a non-parametric method for assessing relative efficiency of decision-making units (dmus). every single decision-maker with the use of inputs produces outputs. these decision-making units will be defined by the production possibility set. resource allocation to dmus is one of the concerns of managers since managers can employ the results of this process to all...
