In the conventional view of the software life cycle, software is produced, delivered to the user, and then enters a maintenance stage. Maintenance is the more expensive and extensive activity, and many surveys exist that analyze it in terms of constituent activities such as corrective, perfective, adaptive maintenance, etc. In this paper, we suggest a different view that partitions the conventi...

Excessive downtime remains a problem for many organisations, particularly those using complex capital intensive manufacturing processes. To counter this, many use computerised management systems to support various aspects of their maintenance activities including breakdown diagnosis. This paper describes research that has been undertaken to investigate the effectiveness of maintenance informati...

Within the Department of Defense (DoD), mission-critical software maintenance has been reported to cost between $700 million and $20 billion annually. The wide range of estimates results from uncertainty over the definitions of “mission-critical” and “software maintenance” as well as the lack of any catalog of performing activities. The problem is deeper than definitions and level of investment...

For real time embedded systems software performance is one of the most important quality attributes. Although a variety of general activities has been proposed as a basis for controlling and predicting the software performance in software, these activities are not widely used in the maintenance and evolution of embedded platforms. During the maintenance and evolution of an embedded platform, wh...

The study proposed a maintenance rating program (MRP) in Taiwan which combines the methods of DEcision MAking Trial and Evaluation Laboratory (DEMATEL) and Analytic Network Process (ANP) to evaluate maintenance activities accurately. In the view of the provincial and county roads in Taiwan, DEMATEL was employed to compute the effects between criteria through experts’ interviews and questionnair...

If anything good can be said to have come from the Year 2000 systems problem, it is that it has created a heightened awareness of how-long lived most software is and how extensively software maintenance efforts span a system’s productive life. One of the most important maintenance processes deserving study is software evolution,described as the dynamic behavior, growth and change of software sy...

This study aimed at presenting a method for formulating optimal production, repair and replacement policies. The system was based on the production rate of defective parts and machine repairs and then was set up to optimize maintenance activities and related costs. The machine is either repaired or replaced. The machine is changed completely in the replacement process, but the productio...

Information technology applications have proven effective in the maintenance of constructed facilities. The objective of the study is to enhance building maintenance using Radio Frequency Identification (RFID) technology. A data management module is first developed to collect building usage and maintenance data. A statistical module is then established to graphically display the collected data....

As attention to environmental problems grows, product life cycle management becomes a crucial issue in realizing a sustainable society. Our objective is to provide the functions necessary for society while minimizing material and energy consumption. From this viewpoint, we should redefine the role of maintenance as a prime method for life cycle management. In this paper, we first discuss the ch...

The world economic image has been changing. It has been a long time since the sole important resources of an organization were financial and physical. In the newly-emerged global economy, knowledge and information are accounted as the most significant resources in order to produce value. Obviously, as the demand for knowledge to reach success is increasing day by day, maintenance and enhancemen...
