Decision making (DM) is an important problem in most of the armyoperations. One of the challenging issues in this area is uncertainty in warswith uncertain information which causes many destructive effects on theresults of strategies in battlefields. In the Heravi et al. article’s, published inthe year 2013, utilizing a combination of Cognitive Agent (CA) andClassification based on Fuzzy Association Rules (CFAR) as the mosteffective and widely used methods, was able to relatively reduce thisproblem and tried to reduce uncertainty. But still in critical condition, can’tdeny the need to act quickly and remove most invalid and inefficient rulesextracted in the effective decisions.This paper aims to utilize the capabilities of Genetic Algorithm (GA) in amore realistic selection rules as a meta-heuristic way to combinecomplementary methods to minimize the uncertainty in DM. In comparisonwith previous method, experimental results achieved, clearly show that thiscombination in addition to the advantages of the previous method, due to thefurther reduction of production rules for DM, are more understandable andaccurate and has more rational risk acceptance.

This article suggests a new method for solving multi-criteria decision making issues. The method has been designed by simple but rational mathematical logic based on a specific geometric definition of the options. Understandable content as well as algorithm simplicity and simplified process are the rich standing points of the approach. Such problems have always had a brand-new geometric approach whilst the calculations involved in this method are benefiting from the lack of complex and complicated steps and the essential patronized path. Categorizing the enriched method's significances, we may finally come up with the availability of graphical model provided for the users. The users are properly enabled to enlighten presenting a geometric logic.

The important factors affecting the information search process and following it the decision making for buying, have been widely under survey that the result of this survey shows that this ingredient includes: market specialty, product specialty, consumer specialty and situational condition.
In case of consumer specialty, elements like social condition, age, degree of learning, people's knowledge with different kinds of products and their perception of risk have been accurately under survey.
But this research for the first time in Iran by studying the consumer life style which consist of group of inside and outside ingredients have a comprehensive and supplementary point of view which trying to study the role of life style in Iranians kind of decision making for purchasing.
Considering different existing defragment of consumer behavior we have four kinds of decision making including: extended decision making, limited decision making, decision making based of loyalty to commercial brand and compulsory decision making.
In this research by the use of statistical methods including .r2 and Gamma coefficient have been processed the kind of dominant decision making in VALS life style consist of following innovators, experiences, achievers, believers by survey method. Finally it have been determine that the dominant kind of decision making for innovators is extended decision making and for achievers is limited kind of decision making but there isn't a considerable different between two remaining kinds of life style including experiences and believers. So as a result these two life styles will use the four kinds of decision making in the same.
