Fuzzy Based Good Software Design

-Fuzzy was introduced by prof. L.A. Zadeh. It is mainly branch of mathematics especially discrete mathematics. It is also the part of artificial intelligence. In fuzzy theory there are no rigid boundaries like 0 or 1. Fuzzy lies between 0 and 1. Fuzzy logic is a logic theory; it uses mainly two types of methods for fuzzy inference mamdani and sugeno. Due to flexible nature of fuzzy theory it can be applied in any field of our life like engineering, science, farming, management, decision making. This paper used matlab for solving problem of good software design. One of the most important phases in software development life cycle is designing phase. In which we decide which type of design is use to develop the software. By The definition of “a good software design” we are depending upon the applications being designed. For example, the size of memory used by a program in any device can be an important issue to full fill a good solution for embedded system software development – embedded applications are often required to implementing using memory of which have limited size due to cost, space, or power consumption considerations. For embedded applications, one may sacrifice design comprehensibility to achieve code compactness. In embedded applications, many factors such as design comprehensibility can take a back seat while judging the betterment of design. Therefore, many criteria used to judge how good a given particular design solution is can vary depending upon the application. Not only is the betterment of design depended on the targeted applications, but also the notion of betterment of a designing itself varies widely across academicians and software engineers. However, most software engineers and researchers agreed on a few desirable features that any good software design for general Application must possess. The characteristics are listed below:Efficiency: It should be efficient Understandability: A good design is easily understandable. Correctness: A good design should correctly implement all the Functionalities identified in the SRS document. Maintainability: It should be easily amenable to change.
