Earth pressure balance tunnel boring machines (EPB-TBMs) are favorably applied in urban tunneling projects. Despite their numerous advantages, considerable delays and high maintenance cost are the main disadvantages these machines suffer from. Reliability, availability, and maintainability (RAM) analysis is a practical technique that uses failure and repair dataset obtained over a reasonable ti...

Maintainability is an important character which is given by product design process. The maintainability design criteria and measure index used in product maintainability analysis are summarized and discussed in this paper. A product maintainability design method is studied by integrating the product feature model, maintainability design criteria with measure index. Product feature model can be ...

There is always has been a demand to provide efficient and effective high quality software. There are various maintainability objects to provide better maintainability. The quality of good software design heavily effective the quality of software. One of the claimed advantages of object-oriented paradigm is ease of maintenance. This paper provides the review on the papers studied on the softwar...

Measuring software maintainability early in the development life cycle, especially at the design phase, may help designers to incorporate required enhancement and corrections for improving maintainability of the final software. This paper developed a multivariate linear model ‘Maintainability Estimation Model for Object-Oriented software in Design phase’ (MEMOOD), which estimates the maintainab...

Software maintenance is a term of major interest and it is a valuable part of software development cycle. One of the main aspects of software quality in software products is maintainability. Further, there are four sub categories of maintainability: analyzability, changeability, stability, and testability. Maintainability plays a vital role in improving software quality as software changes/upda...

Maintainability is an important quality attribute for almost every quality model. Maintainability of the software is considered as most expensive phase in software development life cycle as it consumes almost major part of the total effort allocated to the software system. Maintainability evaluation is complex due to its imprecise output. This paper proposes a maintainability model by consideri...

Maintainability is typically described initially as a non functional requirement at the system level. Systems engineers must subsequently apportion these system requirements very carefully as either software or hardware requirements to conform to the maintainability requirements of the system. A number of concepts are provided in the ECSS, ISO 9126, and IEEE standards to describe the various ty...
