This paper presents an overview of two maintenance techniques widely discussed in the literature: timebased maintenance (TBM) and condition-based maintenance (CBM). The paper discusses how the TBM and CBM techniques work toward maintenance decision making. Recent research articles covering the application of each technique are reviewed. The paper then compares the challenges of implementing eac...

Component-based software engineering has been increasingly adopted for software development. This approach relies on using reusable components as the building blocks for constructing software. On the one hand, this helps improve software quality and productivity; on the other hand, it necessitates frequent maintenance activities, such as upgrading third party components or adding new features. ...

At a different level, corporaA.ts tried to define software written about software maintenance, and tions rely on maintenance to keep their maintenance and determine whether the (4) the industry-wide money-sa...

Software maintenance is a knowledge intensive activity. Implementing effective knowledge management policies and structures during maintenance is therefore a key factor to improving software quality and maintenance productivity. This paper presents a novel agent and goal-oriented analysis technique that was used at Ericsson Marconi Spa to analyze the successful adoption of organizational struct...

A condition based preventive and corrective maintenance policy is proposed for a continuously operating system. The condition of the system is assumed to deteriorate with time. The model incorporates both deterioration as well as random common cause failures. The deterioration stages are modeled as discrete state processes. The system is put to random inspection to know the condition. The mean ...

the management of machine replacement (specifically tractors) is one of the most critical factors for performing field operations on time. therefore, tractor repair and maintenance costs must be accurately predicted. this research was carried out to evaluate the use of the regression technique in predicting tractor repair and maintenance costs. the study was conducted using empirical data on 60...

The paper generalizes a preventive maintenance optimization problem to multi-state systems, which have a range of performance levels. Multi-state system reliability is defined as the ability to satisfy given demand. The reliability of system elements is characterized by their hazard functions. The possible preventive maintenance actions are characterized by their ability to affect the effective...
