Machine maintenance is modeled in the setting of a single-server queue. Machine deterioration corresponds to slower service rates and failure. This leads to higher congestion and an increase in customer holding costs. The decision-maker decides when to perform maintenance, which may be done preemptively; before catastrophic failures. Similar to classic maintenance control models, the informatio...

Standard scheduling theory assumes that all machines are continuously available throughout the planning horizon. In many manufacturing and service management situations however, machines need to be maintained periodically to prevent malfunctions. During the maintenance period, a machine is not available for processing jobs. Hence, a more realistic scheduling model should take into account machi...

The search for a plant maintenance strategy to mitigate the impact of random factory machine failures has never been more challenging. Apart from harsh global competition, manufacturing facilities have become sophisticated and expensive; frequent prolonged breakdowns may ruin firm’s business. Consequently, many turned Preventive Maintenance (PM) solution. However, efficacy PM shown depend on fi...

Accurate descriptions of organ motion due to breathing are highly desirable for radiation treatment planning. This paper proposes an index that quantifies the irregularity of a signal related to respiratory motion. The method works by finding the periodic band-limited signal that best fits the signal samples, and then computing the root mean squared (RMS) residual error. The fitted signal itsel...

Due to reduction in petroleum production and aging production facilities, the Norwegian oil and gas industry is interested in optimization maintenance strategies and reducing costs. Currently the maintenance strategies are based on predetermined periodic (calendar or use time) preventive maintenance strategies that are developed based on statistical data and/or recommendation from the manufactu...

Increased reliance on agile manufacturing techniques has created a demand for systems to solve integrated process-planning and production-scheduling problems in lasge-scale dynamic environments. To be effective, these systems hould provide useroriented interactive functionality for managing the various user tasks and objectives and reacting to unexpected vents. This paper describes the mixed-in...
