We study spare parts inventory control for an aircraft component repair shop. Inspection of a defective component reveals which spare parts are needed to repair it, and in what quantity. Spare part shortages delay repairs, while aircraft operators demand short component repair times. Current spare parts inventory optimization methods cannot guarantee the performance on the component level, whic...

This paper describes a methodology of automatic genetic algorithm parameters adjustment dedicated to a job-shop problem with a no-wait constraint with a makespan criterion. The numerical results show that in a given problem, the efficiency of an algorithm with auto-tuning is placed at the level of an algorithm steered in a classical way with the best-fit steering parameters.

Practical optimization problems such as job-shop scheduling often involve optimization criteria that change over time. Repair-based frameworks have been identi ed as exible computational paradigms for difcult combinatorial optimization problems. Since the control problem of repair-based optimization is severe, Reinforcement Learning (RL) techniques can be potentially helpful. However, some of t...

the outcomes of development of urbanization as pollution of air, water and urban environment are great threats to the health and safety of urban residents. nowadays, urban areas as centers of population and economic activities show high concentrations of pollutants; so that, inconvenient locations of irksome and pollutant jobs in metropolitans such as isfahan city have led to serious threats to...

Nowadays injection molding is probably the most important method of Processing of consumer and industrial goods, and is performed everywhere in the world. The developing of injection molding becomes a competition from day to day. This Process now integrated with computer control make the production better in quality and Better quantity. The trends of producing a plastics product in injection mo...
