Function Point Analysis to knowledge representation of software size measurement

In Function Point Analysis through the technique of case-based reasoning(CBR), use the expert system to measure the software size, is the new method of software measurement, the knowledge representation is the basis of this new method. In this paper, firstly, analyze the role of the function point analysis in the software measurement; then describe the knowledge representation method of Production Rules in detail; finally, propose the data model of the function point analysis for software size measurement, to analyze the Technical complexity factors and their weights of the model, then carry out knowledge representation on function point analysis. The results show that, the knowledge representation used in this paper, can simulate the human thinking process of problem solving, has features as Naturalness, modularity, efficiency, clarity, etc, on the application of Function Point Analysis to measure the size having good reference value.
