Railway maintenance works are performed to reduce the probability of occurrence a failure on components railway infrastructure. The scheduling work is important in supporting normal daily operation railway. By proper scheduling, operational hindrance terms extra travel costs due detouring can be minimized. In addition, contractors given more space execute activities with flexibility. This study...

this paper presents a new bi-objective mathematical model for a permutation flowshop scheduling problem with availability constraint in case of preventive maintenance operations on machines. in this paper, preventive maintenance is flexible and there is not a certain time for the maintenance operation; however, time between two consecutive maintenance operations for each machine should not be g...

The cost of maintenance is too high in mining industry to ignore. This is mainly due to poor understanding of the maintenance process which is greatly influenced by the reliability characteristics of the operating system. The paper introduces an approach for maintenance scheduling of a mining system based on reliability analysis which is divided into two parts. The first part introduces a metho...

This paper introduces predictive framework for asset management risk assessment that utilizes big data. It describes the data analytics required for integrating the big data in time and space. The proposed assets management framework is novel since it implements a dynamic proactive maintenance scheduling. The dynamic maintenance scheduling overpowers the conventional periodic scheduling, by tak...

scheduling has become an attractive area for artificial intelligence researchers. on other hand, in today's real-world manufacturing systems, the importance of an efficient maintenance schedule program cannot be ignored because it plays an important role in the success of manufacturing facilities. a maintenance program may be considered as the heath care of manufacturing machines and equip...

This paper presents a hybrid particle swarm optimization based genetic algorithm and hybrid particle swarm optimization based evolutionary programming for solving long-term generation maintenance scheduling problem. In power system, maintenance scheduling is being done upon the technical requirements of power plants and preserving the grid reliability. The objective function is to sell electric...

Generation or transmission maintenance scheduling packages provide preventive or corrective maintenance scheduling over a certain period in order to minimize system costs while fulfilling relative requirements. In advanced power systems inclusion of network constraints and increasing rate of electricity demand may result in higher number of generators and transmission lines and hence lower syst...

Aircraft maintenance planning and scheduling constitute planning, control and execution of materials (spare parts), operations (inspection, disassembly and assembly activities) and resources (labour, machines, transport equipment, etc.). This is a complex problem due to large number of components involved at various planning and execution levels, and the size/nature of resource-intensive mainte...
