The application of genetic algorithm in the development of preventive maintenance analytic model

Preventive maintenance and replacement scheduling : models and algorithms.

“…In addition and as a case study, they apply their model to a high-pressure injection system to measure the effectiveness oftheir methodology. Shum and Gong (2007) recently present an application of a genetic algorithm to optimize preventive maintenance schedules of a production machine. They consider maintenance and replacement frequency along with purchasing strategy and the size of the maintenance workforce as the decision variables and total cost as the objective function.…”

Investigation of various maintenance parameters for auxiliaries in a coal‐handling plant aided by a Visual Basic 6.0–based scheduled program

“…Several works exist on maintenance optimization for fault diagnosis in various process plants in the literature. [8][9][10][11][12][13][14][15] Most optimization studies are observed to be based on mathematical modeling, which are time consuming and complicated, and well suited for large process plants. [15][16][17][18][19][20][21][22][23][24][25] Therefore, this software has been developed to address such issues for CHP department in thermal power station.…”

“…Difficulty in finding failure rate ‐ If the total working hours of spare parts and auxiliaries are not known, computing the failure rate is not possible. If failure rate is not known, then it is difficult to decide whether there is a need for a design modification or requirement of retrofitting for auxiliaries More time consumed in record keeping ‐ Keeping records of all spares and failure is one of the responsibilities of the maintenance department .…”

Optimization of Preventive Maintenance in Chemical Process Plants

“…The most common optimization criteria is cost minimization, which can be maintenance cost only 6 or total cost, that is, maintenance cost, inventory cost and maintenance labor cost. 13 For systems like nuclear power plants or power generation systems where reliability is much more important than cost, the optimization criteria are reliability measures constrained by a given maintenance budget. 14 Most of the research works dealt with maintenance planning, the upper level in the maintenance management hierarchy.…”
