This paper considers the scheduling of preventive maintenance for boilers, turbines, and distillers power plants that produce electricity desalinated water. It models problem as a mathematical program (MP) maximizes sum minimal ratios production to demand water during planning time horizon. objective encourages plants’ enhances chances meeting consumers’ needs. reduces chance cuts shortages may...

Abstract. A large part of the operational cost for a wind farm is due to equipment maintenance, especially offshore farms. How reduce maintenance cost, and hence increase profitability, this article's focus. It presents binary linear optimization model whose solution may inform turbine owners about which components, when, should undergo next preventive (PM) replacements. The suggested short-ter...

Usually, scheduling of maintenance operations and production sequencing are dealt with separately in the literature and, therefore, also in the industry. Given that maintenance affects available production time and elapsed production time affects the probability of machine failure, this interdependency seems to be overlooked in the literature. This paper presents a comparative study on joint pr...

Preventive maintenance is essential for every chemical production site to prevent failure and accidents, however it upsets material and utility flows inside the site and also causes production loss. In order to minimize the loss, maintenance of each plant unit has to be carefully scheduled together with considerations on site-wide material and utility balances. This will involve both production...

This paper presents a dynamic grouping maintenance strategy for multi-component systems with positive economic dependence, which implies that combining maintenance activities is cheaper than performing maintenance on components separately. Preventive maintenance durations and occurrences of maintenance activities within the scheduling horizon are considered. Moreover, in presence of opportuniti...

Traditional maintenance planning is based on a constant maintenance interval for equipment life. In order to consider economic aspect for time based preventive maintenance, preventive maintenance is desirable to be scheduled by RCM(ReliabilityCentered Maintenance) evaluation. So, Markov state model is utilized considering a stochastic state in RCM. In this paper, the Markov state model which ca...
