The evaluation and performance analysis of software architecture at the design level increases the quality of the software and also reduces the cost of rework during the later stages of the product. The derivation of performance results of a software product, during the early stages of the software life cycle can be achieved by quantitatively evaluating the software performance model. There has been lot of research identifying the methods of evaluating software (Booch, 2001). The evaluation process starts by analyzing the performance model which is derived from the software model annotated with suitable usage profiles. This paper provides a simple approach to convert the software models represented as Unified Modeling Language (UML) diagrams using the profile for Schedulability, Performance and Time specifications (SPT) into Layered Queuing Network (LQN) performance models. The paper mainly illustrates the conversion process from UML to LQN, and also substantiates the method by a simple example.Keywords

Background/Objectives: Classification of preterm birth is a major challenge in the absence of effective tools and lack of domain knowledge with minimized set of rules. Objective of this paper is to classify the preterm birth with optimized rules. Methods/Statistical Analysis: This paper, proposes mutated Particle Swarm Optimization in order to achieve better result. Cognitive component was obtained by applying the mutation technique followed in the evolutionary algorithm. Mutation phase helped in converging to the optimized solution much faster. Findings: Preterm dataset of 1052 records with 5 attributes was applied to the proposed algorithm. Mutation was applied based on the Poisson, Gaussian, Uniform and Exponential distributions. The result shows that Poisson mutation among other distributions applied on the personal best has reduced the number of rules needed for classifying preterm birth datasets for both training and testing. It was observed that the optimized 13 rules out of 28 for training dataset and 9 rules out of 28 rules wereonly needed for classification. Application/Improvements: The proposed algorithm was suitable for preterm birth data set. This can be applied on the dataset with medium initial population. It was observed thatthe efficiency of the algorithm varied depends on the type of data. Therefore a generic method can be developed.Keywords

The evaluation and performance analysis of software architecture at the design level increases the quality of the software and also reduces the cost of rework during the later stages of the product. There has been a lot of research in the area of software architecture and software design evaluations. When the design is to be improved based on the evaluation results, we lack in a feedback mechanism addressing the issues to be concentrated for design improvement. The paper aims at bringing out inter relationships among the various performance attributes, thereby identifying the specific changes that have to be brought about in design to satisfy customer requirements. The paper addresses a simple methodology using ranking and Karl Pearson method to find the critical areas to be updated for design improvements.Keywords
