The assessment of the changeability of software systems is of major concern for buyers of the large systems found in fast-moving domains such as telecommunications. One way of approaching this problem is to investigate the dependency between the changeability of the software and its design, with the goal of finding design properties that can be used as changeability indicators. In our research,...

Over the years, cumulative data have shown that maintenance is a major cost concern, as a matter of fact, a growing cost concern (Pigosky, 1997). The maintainability of a system seems to have much influence on the ease or difficulty to implement changes. A consensus has emerged that the maintainability of a software system is dependent on its design (Rombach, 1990), in the procedural paradigm a...

the present research aims to develop a model and assess changeability grounds in public organizations. the statistical population includes public organizations in the cities of lamerd and mohr. the research includes three fundamental stages, each of which tries to answer a key question. to devise a proper model, we initially study the theoretical literature of change management and the resistan...

Growing maintenance costs have become a major concern for developers and users of software systems. Changeability is an important aspect of maintainability, especially in environments where software changes are frequently required. In this work, the assumption that high-level design has an influence on maintainability is carried over to changeability and investigated for that quality characteri...

Among the maintainability sub-characteristics, changeability plays a critical role in analyzing the maintainability of software. Changeability is highly influenced by the dependencies that exist between the components of a system. Therefore, we need to have measurement mechanisms that can take into account the dependencies between components so as to determine the ease which modifications can b...

Maintenance is one of the major concerns of software developers and industries. The success of this critical phase depends highly on the changeability of the software. In order to evaluate the flexibility of a software to accommodate changes, we have defined a change impact model for object-oriented systems. As previously defined, it calculates the impacted classes due to an atomic change. In t...

Abstract On the way to automated layout planning numerous challenges must be faced. One of these is evaluation, which can considered as core planning. The research field factory differs from related topics such facility (FLP) operations (OR) by focusing for example on qualitative criteria in evaluation. However, findings how interpreted a quantifiable and measurable are still rare. In this arti...
