Survey on Model-based Performance Prediction of Component-based Software

Introducing performance requirement in early stages of software development process and predicting the performance of under-developed system by performance modeling can greatly reduce the project venture. A series of concepts in performance prediction (PP) of component-based software were brought up, and the diversity of performance models was compared in describing ability and analysis difficulty. Based on summing up common PP methods, the general course of model-based PP was extracted out. Three categories of approach on model-based PP of component-based software were introduced, and analyzed and compared from nine aspects subsequently. Some disadvantages of study on PP were discussed. Some significantly promising research directions were pointed out.
