This paper concerns the modelling of maintenance activities in a distributed context. In this work we study the particular case where the maintenance activities are executed by two workshops: a central maintenance workshop (CMW) and a mobile maintenance workshop (MMW). The (CMW) concerns the repairing process for the corrective maintenance and the (MMW) execute all preventive maintenance in sev...

Abstract Maintenance policy selection for vessel equipment is a multiple criteria decision making. To ensure security, reliability and efficiency of vessel equipment, a maintenance decision model based on risk, availability and cost was proposed according to the characteristics of vessel equipment maintenance. For modeling, analytic network process (ANP) has been employed. And the maintenance p...

Context: Measurement programs have been around for several decades but have been often misused or misunderstood by managers and developers. This misunderstanding prevented their adoption despite their many advantages. Objective: In this paper, we present the results of an empirical study on the impact of a measurement program, MQL (“Mise en Qualité du Logiciel”, French for “Quality Software Dev...

The study seeks to show how online remote condition monitoring helps to improve the maintenance system in a power plant from mainly predetermined and corrective approach to predictive maintenance and, the resultant benefits of its adoption. The findings clearly indicate the various aspects of online remote condition monitoring system which thermal power plants can consider to improve on plant s...

Expensive physical capital must be regularly maintained for optimal efficiency and long-term insurance against damage. The maintenance process usually consists of constantly monitoring high-frequency sensor data and performing corrective maintenance when the expected values do not match the actual values. An economic system can also be thought of as a system that requires constant monitoring an...

The continuous alignment of organizational processes with an organizations’ business strategy is a key factor to its success. This paper reports on the application of the i* framework to support the continuous alignment of corrective software maintenance processes with the strategic goals of a Software Design Maintenance Organization at Ericsson Marconi Spa. Using the i* modeling framework, ali...

Flexible manufacturing cells (FMCs) often operate with increasing failure rate due to extensive utilization and wear-outs of equipment. While maintenance plans can eliminate wear-out failures, random failures are still unavoidable. This paper discusses a procedure that combines simulation and analytical models to analyze the effects of corrective, preventive, and opportunistic maintenance polic...

Maintenance staff fatigue is one of the key factors contributing to occurrence errors in maintenance. The problem maintenance a serious challenge for aircraft organizations, and its solution directly related impact on flight safety. authors consider issues effect performance consequences. article provides results research, obtained through survey organizations` employees. According survey, are ...
