Optimal Preventive Maintenance Planning for Water Spray System of Drum Shearer

Integrated Inspection Planning and Preventive Maintenance for a Markov Deteriorating System Under Scenario-based Demand Uncertainty

In this paper, a single-product, single-machine system under Markovian deterioration of machine condition and demand uncertainty is studied.  The objective is to find the optimal intervals for inspection and preventive maintenance activities in a condition-based maintenance planning with discrete monitoring framework. At first, a stochastic dynamic programming model whose state variable is the ...

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...

Adaptive height adjusting strategy research of shearer cutting drum

Shearer height adjusting is a key technology for shearer automation. Considering constraints of present shearer height adjusting, this paper built grey-markovian memory cutting algorithm after analyzing traditional shearer memory cutting algorithm. We firstly constructed prediction mechanism using grey model, then determined state transition probability matrix using markovian, so as to revise f...

A maintenance system model for optimal reconfigurable vibrating screen management

The reconfigurable vibrating screen (RVS) machine is an innovative beneficiation machine designed for screening different mineral particles of varying sizes and volumes required by the customers’ through the geometric transformation of its screen structure. The successful RVS machine upkeep requires its continuous, availability, reliability and maintainability. The RVS machine downtime, which c...
