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.

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...

introduction: efficiency evaluation of universities and faculties is one of the tools that help managers to identify the departments’ strengths and weakness. the main objective of the present research was to measure and compare the technical efficiency of shiraz school of medicine departments using data envelopment analysis (dea) technique. methods: this cross-sectional and retrospective study ...

in this paper, the energy efficient resource allocation in noma-based heterogeneous cellular network(hcn) systems is investigated. since energy consumption and its limitations is one of the important challenges in fifth generation of cellular networks (5g), we propose a resource allocation problem which allocates power and subcarriers to multiple users to achieve the best system energy efficien...

in this research, both resource allocation and reactive resource allocation problems in multi-server dynamic pert networks are analytically modeled, where new projects are expected to arrive according to a poisson process, and activity durations are also known as independent random variables with exponential distributions. such system is represented as a queuing network, where multi servers at ...

introduction: family physician plan in iran was conducted to establish service referral system. its urban step began in 2012 and it was supposed that the effectiveness is enhanced and the costs are reduced. the implementation of this program has faced some challenges, especially in human resources management. the aim of this study was to optimally allocate human resources for urban family physi...
