چکیده
The maintainability of the software system is becoming a very important characteristic due to growth in demand of quality software system. Software maintainability means the ease with which a software system or component can be modified to correct faults, improve performance or other attributes or adapt to a changed environment. The selection of best maintainability model is prime concern for developing quality software system. Every software maintainability model has some sub-characteristics which impact on maintainability directly or indirectly. This paper presents different maintainability models from various standards and quality models define its sub-characteristics and then perform analytical comparison of these sub-characteristics. Keywords-maintainability, software system, model, measurement

Maintainability measure based on operating environment, a case study: Sungun copper mine
The life cycle cost of a system is influenced by its maintainability. Maintainability is a design parameter, whose operational conditions can affect it significantly. Hence, the effects of these operational conditions should be quantified early in the design phase. The proportional repair model (PRM), which is developed based on the proportional hazard model (PHM), can be used to analyze mainta...

متن کاملA Comparative Study of the Views of Kristjansson, Battaly and Martyr Motahhari on the Effect of Theoretical Wisdom and Modeling on Moral Character
“Moral character” is a subject related to the psyche and an important topic in moral psychology. The question is whether the formation of moral character is inherent and unchangeable. If it is acquired, what factors affect it? If a character becomes vicious, is it possible to correct it? Considering the importance of the aforementioned questions, it was necessary to study the issue of “shaping ...
