The cross efficiency evaluation is used to performance measurement of decision making units in data envelopment analysis concept. One of the most important shortcoming of this method is existing alternative optimal solution and therefore, the efficiency scores are not unique. We are going to summarize the pervious models proposed by researchers and suggest an alternative secondary goal approach...

The correlated models are introduced in this article regarding revenue efficiency and profit efficiency in dynamic network production systems. The proposed models are not only applicable in measuring efficiency of divisional, periodical and overall efficiencies, but recognizing the exact sources of inefficiency with respect to revenue and profit efficiencies. Two numerical examples, consisting ...

Efficiency evaluation of units has been of interest since many years in different domains such as management, economy, business, banking, and many others. Data envelopment analysis is one of the popular operations research methods for measuring the relative efficiency of units, which use multiple inputs to produce multiple outputs. As we know, universities play a key role in many aspects of a c...

In this paper, we investigate the existence of Pareto and weak Pareto equilibria for multiobjective games without compactness. By employing an existence theorem of Pareto equilibria due to Yu and Yuan([10]), several existence theorems of Pareto and weak Pareto equilibria for the multiobjective games are established in a similar way to Flores-Bázan([4]).

I summarize and extend my results establishing that limited arbitrage is necessary and sufficient for the existence of a competitive equilibrium and for the compactness of the Pareto frontier [11] (announced in [14] and [8]). In response to a comment [36], I show that the authors misunderstood my results by focussing on brief announcements [14] and [8] which did not detail the hypothesis, rathe...

In runtime enforcement of security policies, the classic requirements on monitors in order to enforce a security policy are soundness and transparency. However, there are many monitors that successfully pass this specification but they differ in complexity of both their implementation and the output they produce. In order to distinguish and compare these monitors we propose to associate cost wi...

This paper studies strategic information transmission in a dynamic environment, where a privately informed expert and a decision maker interact for a …nite number of periods. Our theoretical results argue that the dynamic cheap talk games are fundamentally di¤erent from static ones. First, information can be fully revealed. Second, there exist non monotonic equilibria. Third, there is no genera...
