<br/><br/> This thesis is directed towards developing two new fuzzy logic representations for systems modeling and optimization using the notion of the normalized fuzzy matrices.The first is the arithmetic type based on dual cell representation , expressed by replacing each parameter with a pair of parentheses , the first is the actual value and the second is corresponding fuzzy level , value fuzzy level
