Abstract
Managerial researches emphasize an organizational contingency elements rule at improving the performance. Although, few theorical and empirical researches were implemented upon the influencing elements at organizational performance.
This paper is an effort to fill gaps of corresponding issue. For this, exploration and searching the literature and expert interviews (DELPHI) resulted in formulation of 14 contingent elements which impact the military organization performance. Then, an importance- performance analysis technique based on experts needs and expectations was used to prioritize the elements performance. This technique also presents weakness and strength of influencing performance elements.
In this paper, to improve the validity and practical aspects of importance- performance analysis technique, experts and personnel of mentioned organization were interviewed.
Then, two quantitative and qualitative techniques multiple regression and DEMATEL final values as integration of implicit and explicit importance respectively are used to extract the importance rates.
Finally, the performance rate extracted through interviews based on likert values as well as importance rate applied to build the importance- performance matrix in four quadrants which based on two axes (importance, performance) to analysis the feature of located elements in each quadrant.

Abstract
The goal of this research is to design and build a solar adsorption chiller operated by activated carbon / methanol. Continuous refrigeration systems are able to produce cooling continuously. This paper examines the effect of activated carbon particles on the performance of a continuous adsorption chiller device. The source of this chiller is through sunlight and supplied by a parabolic collector that does not need to track sunlight. The system operates with two adsorbent beds that, when one is adsorbed, the other is desorbed. The experiments were carried out in Yasuj during three different days in the month of Bahman for three hot water input to the chiller 38℃, 34℃ and 30℃. The average ambient temperature during the experiment is 18℃. Experimental results shows that for the total energy input, 13MJm-2, the average performance factor of the chiller is when the inlet temperature of the hot water of the chiller is 38℃, 34℃ and 30℃, respectively, of 0.123, 0.103 and 0.10. For Previous temperatures the average specific cooling power of the device was obtained at 88Wkg-1, 65Wkg-1 and 50Wkg-1 respectively.
