On a Preventive Maintenance with Monitored System
نویسنده
چکیده
A monitored system consists of a core system and its monitor. A core system follows a general life time distribution, but its state, good or not good, cannot be observed directly. In order to infer the state of the core system, we use the information from the monitor whose states are stochasticalIy related to the states of the core system. Using its information, we make the maintenance policy for the core system so as to minimize the total expected cost incurred by a sequence of actions. This paper shows the conditions under which an optimal maintenance policy for the above model has the form of a control limit policy. Also, a numerical example where the life time of the system follows a WeibulI distubution is presented.

An integrated production and preventive maintenance planning model with imperfect maintenance in multi-state system
Production planning and maintenance are two important problems in manufacturing systems. Despite the relationship exists between these two problems due to sudden failures and production capacity occupied by maintenance activities, each of these problems planned separately and as a result program and model efficiencies reduce in the real world. The aim of integrated production and maintena...

General preventive maintenance model for the components of a system, which improves the reliability to ‘as good as new,’ was used to optimize the maintenance cost. The cost function of a maintenance policy was minimized under given availability constraint. On the other hand, in order to ensure appropriate reliability and availability, the development of the optimal maintenanc...
متن کاملMaintainability Policy for Deteriorating System with Inspection and Common Cause Failure (TECHNICAL NOTE)
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 ...

متن کاملA preventive maintenance policy for a continuously monitored system with correlated wear indicators
A continuously monitored system is considered, that gradually and stochastically deteriorates according to a bivariate non decreasing Lévy process. The system is considered as failed as soon as its bivariate deterioration level enters a failure zone, assumed to be an upper set. A preventive maintenance policy is proposed, which involves a delayed replacement, triggered by the reaching of some p...
