An improved function point analysis(FPA) is proposed according to the project experience.

Leveraging the Function Point Analysis method to build an integrated and feasible software measurement system will help project managers effectively improve each item in software development lifecycle.

Against shortcomings caused by complexity grade division,this paper presents the fuzzy function point analysis method.

Function point analysis is a method used to measure an application s function size,it depends on the implementation programming language and its measuring result can be compared between different development processes.

Existing simplified Function Point Analysis(FPA) methods have different effect among different software individuals,especially when applied to the small-to-medium-sized software,which may result in larger result.

Function Point Analysis(FPA) can only measure the static aspects of systems and can not take the interactions and behaviors of objects into consideration.

Fuzzy comprehensive evaluation modeling for software testing design sufficiency based on function points analysis;

Combining with the result of questionnaire, the author emphasized to introduce and compare of two estimation methods, Function Point Analysis (FPA) and Influencing Factor Analysis (IFA), to find the most suitable method of estimating workload in the project of car navigation.

To adopt function analysis method-this modern mechanical system design method to gain function structure of welding system of copper-aluminum pipe and further gain its morphology matrix through analyzing of general function and the combination of function cell.

In the view of system,the function analysis method,which is one of the modern mechanical system design methods,has been adopted to analyze and design the equipment.
