One of the most complicated decision making problems for managers in supply chain is the evaluation of supply chain performance which can be done in different ways. Though several studies have been developed on supply chain performance evaluation based on balanced scorecard (BSC), a few studies focused on relationships among four perspectives of BSC. This paper focuses on these relationships, e...

A new network architecture based on increasing intelligence of the computing nodes is suggested for building the semantic grid. In its simplest form, the distributed intelligent managed element (DIME) network architecture extends the conventional computational model of information processing networks, allowing improvement of the efficiency and resiliency of computational processes. This approac...

In this paper, for solving the moral hazard problem of super nodes in VOIP network and achieving better communication quality, we establish a reward mechanism based on classical efficiency-wage models. In the reward mechanism, the function of reward is to encourage super nodes to contribute their bandwidth and cover their effort costs, whereas the function of fine is to prevent opportunistic su...

in this paper, presenting two simple methods for ranking of efficient dmus in dea models that included to add one virtual dmu as ideal dmu and is using the additive model. note that, we use an ideal point just for comparing efficient dmus with. although these methods are simple, they have ability for ranking all efficient dmus, extreme points and the others, also they are capable of ranking the...

the efficiency measurement is a subject of great interest. the majority of studies on dea models have been carried out using radial or non-radial approaches regarding the application of dea for the efficiency measurement. this paper, based on the directional distance function, proposes a new generalized hybrid measure of efficiency under generalized returns to scale with the existence of both r...

The Efficient Clustered Super-Peer P2P network is a novel P2P architecture, which overcomes the efficiency and scalability problems of existing P2P systems. A flooding algorithm, Efficient Flooding Algorithm (EFA) is also introduced to work on this type of network system. However, the Super-Peer network architecture and the behavior of the flooding algorithm are not intuitive. SuperViz project ...

Eco-efficiency is a significant target for evaluating the agricultural ecosystem and measuring sustainable development through quantitative analysis. It also an essential part of constructing ecological tea garden, which offers directional function in realizing green industry. After eco-efficiency China’s industry using super-efficiency SBM model, this paper analyzes spatial disequilibrium dyna...

There has been growing interest in applying the DEM (discrete element method) to study charging and burden distribution a BF (blast furnace). In practice, real particles are non-spherical. However, spherical have mostly used previous investigations. Furthermore, various particle models developed describe non-spherical particles. effects of using different on behavior still unclear. Therefore, c...

Purpose Seaports are a signifier for the world economy and international trade. Notwithstanding considerable role of Chinese ports in global trade, only few studies have explored efficiency container terminals. Furthermore, on port has typically centered port-level analysis, not terminal level. Therefore, this study aims to examine operation Design/methodology/approach This uses super-efficienc...
