In order to better estimate the software development cost,a software cost estimation system is designed and realized.Firstly,a three-phase estimation model is introduced based on the current standards in China.This model first calculates the software scale based on the function points of the software,and then uses the scale to estimate the efforts and total cost required for development.On this basis,the software cost estimation system is developed.Application cases show that the system has a high estimation accuracy.
