Reward criterion is an important decision factor in a Markov-based road maintenance optimization model. At present, average reward criterion or discounted reward criterion is widely used to optimize life cycle costs of road maintenance. However, the former one cannot reflect the time value of life cycle costs whereas the latter one tends to neglect the costs accumulated in the later periods ove...

Chapter 17 of the HCM 2000 provides a method for analyzing a two-stage priority process at unsignalized intersections, which provide a wide median in the major street. In the HCM itself, the method is, however, described rather briefly. This could give rise to misunderstandings, and practitioners might avoid using the procedure altogether. This being so, the analytical background of the procedu...

Object oriented designing is an essential part of software environment. This study focuses on a set of object oriented metrics that can be used to measure the maintainability of an object oriented design. These metrics for object oriented design focus on measurements that are applied to the class and design characteristics. These measurements permit designers to access their software early in p...

Impact analysis is needed for the planning and estimation of software maintenance projects. Traditional impact analysis techniques tend to be too expensive for this phase, so there is need for more lightweight approaches. In this paper, we present a technique for the generation of lightweight impact analyzers from island grammars. We demonstrate this technique using a real-world case study in w...

the nature of software re-engineering is to improve or transform existing software so it can be understood, controlled and reused as new software. Needs, the necessity of re-engineering software has greatly increased. The system software has become obsolete no longer used in architecture, platform they're running, stable and consistent they support the development and support needs change. Soft...

Conventional maintenance strategies on a single component are being phased out in favour of more predictive maintenance actions. These new kinds of actions are performed in order to control the global performances of the whole industrial system. They are anticipative in nature, which allows a maintenance expert to consider non-already-planned maintenance actions. Two questions naturally emerge:...

In recent decades, by introducing lean manufacturing the vulnerability to system disturbances has increased and so, the demand for dependable production equipment. The need for having high production equipment availability causes companies to need a more effective and efficient maintenance strategy in order to stay competitive. Despite the increasing demand on reliable production equipment, few...
