Abstract: Because the mixed source software(MSS) contains independent code,open source code and other different codes,the MSS has higher diversity and complexity,and quality measurement is greatly different between traditional software.In order to measure the MSS,it is very essential to establish measurement model and method.Based on MSS quality property,this paper put forward mixed source software quality model. Then we used the analytic hierarchy process,power method and linear method to build measurement method system.Finally we performed an experimental measurement on UbuntuKylin operating system.The experimental results shows the effectiveness,feasibility of the model and method.

Key words: Mixed source software,Quality model,Software measurement,Independence and controllability,Measure methods
