A Dynamic Maintenance Strategy for Multi-Component Systems Using a Genetic Algorithm
نویسندگان
چکیده
In multi-component systems, the components are dependent, rather than degenerating independently, leading to changes in maintenance schedules. this situation, study proposes a grouping dynamic strategy. Considering structure of strategy is determined according importance components. The can minimize expected depreciation cost system and divide into optimal groups that meet economic requirements. First, models grouped. Then, failure probability model systems established. parameters each cycle updated Second, component indicator introduced model, optimization which aimed at maximum profit, A genetic algorithm used solve non-deterministic polynomial (NP)-complete problem obtained through initial by random allocation. An 11-component series parallel illustrate effectiveness proposed strategy, influence on discussed.

Maintenance grouping strategy for multi-component systems with dynamic contexts
This paper presents a dynamic maintenance grouping strategy for multi-component systems with both “positive” and “negative” economic dependencies. Positive dependencies are commonly due to setup cost whereas negative dependencies are related to shutdown cost. Actually, grouping maintenance activities can save part of the setup cost, but can also in the same time increase the shutdown cost. Unti...
متن کاملA dynamic predictive maintenance policy for complex multi-component systems
The use of prognostic methods in maintenance in order to predict remaining useful life is receiving more attention over the past years. The use of these techniques in maintenance decision making and optimization in multi-component systems is however a still underexplored area. The objective of this paper is to optimally plan maintenance for a multi-component system based on prognostic/predictiv...

متن کاملChaotic Genetic Algorithm based on Explicit Memory with a new Strategy for Updating and Retrieval of Memory in Dynamic Environments
Many of the problems considered in optimization and learning assume that solutions exist in a dynamic. Hence, algorithms are required that dynamically adapt with the problem’s conditions and search new conditions. Mostly, utilization of information from the past allows to quickly adapting changes after. This is the idea underlining the use of memory in this field, what involves key design issue...
متن کاملA genetic algorithm approach for a dynamic cell formation problem considering machine breakdown and buffer storage
Cell formation problem mainly address how machines should be grouped and parts be processed in cells. In dynamic environments, product mix and demand change in each period of the planning horizon. Incorporating such assumption in the model increases flexibility of the system to meet customer’s requirements. In this model, to ensure the reliability of the system in presence of unreliable machine...
