Improvement in the V-Model
نویسنده
چکیده
The V-model represents a software development process (also applicable to hardware development) which may be considered an extension of the waterfall model. Instead of moving dow n in a linear w ay, the process steps are bent upwards after the coding phase, to form the typical V shape. The V-Model demonstrates the relationship between each phase of the development life cycle and its associated phase of testing. The horizontal and vertical axes represents time or project completeness (left-to-right) and level of abstraction (coarsest-grain abstraction uppermost), respectively. This model depends on verif ication and validation phase Software Testing is the most important phase of the Software Development Life Cycle. On most software projects testing activities consume at least 30 percent of the project effort. On safety critical applications, software testing can consume between 50 to 80percent of project effort. Software testing is essential to ensure software quality. Schedule is always running tight during the software system development, thereafter reducing efforts of performing software testing management. In such a situation, improving sof tware quality becomes an impossible mission It is our belief that software industry needs new approaches to promote software testing management. The article discussed the model that already existed, further excavates the parallelism betw een test stages and maintenance test stages and tries to propose a improved V model. This model makes the software testing pass through the each stage of software development cycle.

This paper proposes fuzzy modeling using obtained data. Fuzzy system is known as knowledge-based or rule-bases system. The most important part of fuzzy system is rule-base. One of problems of generation of fuzzy rule with training data is inconsistence data. Existence of inconsistence and uncertain states in training data causes high error in modeling. Here, Probability fuzzy system presents to...
متن کاملA Control Strategy for Flywheel Energy Storage System for Frequency Stability Improvement in Islanded Microgrid
The Micro-Grid (MG) stability is a significant issue that must be maintained in all operational modes. Usually, two control strategies can be applied to MG; V/f control and PQ control strategies. MGs with V/f control strategy should have some Distributed Generators (DGs) which have fast responses versus load changes. The Flywheel Energy Storage System (FESS) has this characteristic. The FESS, w...
