| Currently, due to the fast development of information industry and a higherprofessional level of users, it has shown a higher demand for software performance.Besides a myriad of applied software have sprang in the market for customers tochoose. However, as the output of the software has no regularity, leading to a largenumber of software only used for once ends to be neglected and causing a huge wasteof resources. As software reuse engineering is still under development, choosingexisting software can reduce the cost, at the same time, in multiple application it canput forward relevant product application upgrade option, which will help enterprisesmake the possible end of the software products. How to give its vitality, continue torealize its value, and help users select the software suited to their needs will be thefocus of this paper.Software practicality can be defined as: the ability for software products to meetusers’ needs in a satisfying manner. This paper, from the approaches of softwarefunctional character, software engineering, software quality evaluation and otherrelated knowledge, focuses on improving the evaluation problem according to theability demonstrated in application and afterward effects. Moreover, based thecharacter of software, it proposes the definition of software practicability and makes adeep analysis on its property model; describes software practicality from the twostages of application process and application achievement. It combines the AHPtheory with methods of fuzzy assessment to make a draft evaluation on softwarepracticality; to meet the customers’ needs, establishes a demand-driven dynamic indextree models, and designs a dynamic expansion of the practicality of indexes database.On this basis, it founds a draft evaluation model on software practicality, elaboratingon the framework of the index classification and on the rough evaluation methodbased on AHP software practicality.In conclusion, the thesis obtains the objective of assessing the target software’spracticality based on the fundamentals of software practicality with a realizedevaluation system. The goal is achieved with the assistance of a project-crediblenational software resource sharing and collaborative production environment in powergeneration production management system, as well as by choosing the FODM,collecting evaluation data. All the above work gives a full display of the significance of the paper: an effective verification of software practicality analysis mechanism, thereconstruction of software value, a more real and efficient display of softwareinformation, and moreover, valid references for users to consult when choose suitablesoftware. |
