EVALUATING THE PARAMETERS FOR SELECTING THE BEST METHOD FOR THE PRE-PARATION OF NANOCRYSTALS BY USING FUZZY ANALYTIC HIERARCHY PROCESS

摘要

The aim of this paper is to select the best method for the preparation of nanocrystals by using the fuzzy analytic hierarchy process (Fuzzy-AHP) methodology. The commonly used methods for the preparation of nanocrystals are Hydrosol, sonoprecipitation, spray freezing into liquid, and Nanomorph?. There are several parameters to take into consideration for the selection of the best method like operational skill, technical information, benefits, expenditure, etc. To improve the traditional AHP, Fuzzy concepts are applied because it is well organized and logical compared to other decision making technique. In order to avoid the controversial of fuzzy ranking process, the α-cut-based method has been used. Based on the results of FAHP it is concluded that sonoprecipitation is the best method for the preparation of nanocrystals. The fuzzy approach gives a more apt and agreeable result compared to the traditional AHP. Our study shows that the FAHP is a suitable and constructive approach to select the best method for the preparation of Nanocrystals. This study reveals that sonoprecipitation method is the most appropriate technique for the preparation of nanocrystals.
