the productivity change of a decision making unit (dmu) between two time periods can be evaluated by the malmquist productivity index. in this study, we propose a method to compute the malmquist productivity index in several time periods (from the first to the last periods) on interval data in data envelopment analysis (dea). then, the obtained malmquist productivity index is compared with malm...

A severe threat encountered in many international peacekeeping and peace forcing operations is that of rockets, artillery, and mortars (RAM) fired by insurgents towards military bases, troops, and other assets. Attacks like these have cost many human lives in places like Iraq and Afghanistan during recent years. Similar attacks are faced by civilians in some parts of Israel on a regular basis, ...

The present paper provides a theoretical account of the auditory recognition process. The theory describes recognition in terms of the information in a preperceptual auditory image and the time it is available for perceptual processing. Auditory recognition processes are assumed to be analogous to those operating in visual recognition. Necessary distinctions are drawn between auditory detection...

Two stages DEA models are used in many fields of management and industry. One of the concepts that has attracted the attention of researchers in the theory of production is the concept of ranking the units with a two-stage network. A unit ranking can provide useful information to decision makers (DMUs) about optimal decision making activities. This concept defines the superiority of a unit in t...
