We address a novel integrated maintenance and production scheduling problem in a multi-machine and multi-period production system, considering maintenance as a long-term decision. Deterioration of machines over time decreases production capacity. Since maintenance activities improve machine conditions, increasing production capacity, but also take time that cannot be used for production, the ch...
Smart distribution networks (SDNs) plays a significant role in future power networks. Accordingly, the optimal scheduling of such networks, which include planning of consumers and production sections, inconsiderably concerned in recent research studies. In this paper, the optimal planning of energy and reserve of SDNs has been studied. Technical constraints of distribution network and power gen...
the purpose of this study was to investigate the effect of task repetition on accuracy of iranian efl learners ’speaking ability. in order to achieve this purpose, a null hypothesis was developed: there is no statistically significant difference between accuracy speaking ability in iranian efl learners by use of task repetition. ; of course i should mention that, beside this null hypothesis, an...
This paper outlines the way the planning/scheduling applications can be solved using the optimization potential of the Choco CSP solver. Consequently two specific problems which can be applied in various fields were described in this paper. The first one is a pure planning problem and supposes that a factory should manufacture products ordered by a client in the shortest time possible. The seco...
Increasing demand for customized products in the wake of 4th Industrial Revolution is placing ever increasing demands on flexibility manufacturing systems. Furthermore, usage automated guided vehicles (AGV) adds another layer and also complexity to overall production system. The resulting Flexible Job Shop Scheduling Problem (FJSSP), including coordination AGVs, NP-hard therefore hard optimize....
Theoretical scheduling has reached a mature state but there are difficulties in using the theory in practice. One of the issues is the occurrence of disturbances. Studies have been done to investigate the possibility of using control chart techniques to detect disturbances in production planning and scheduling. Appropriate control chart techniques have been developed that avoid statistical prob...
To be successful in multi-player drone racing, a player must not only follow the race track in an optimal way, but also avoid collisions with the opponents. Since unveiling one’s own strategy to the adversaries in not desirable, this requires each player to independently predict the other players future actions. Nash equilibria are a powerful tool to model this and similar multi-agent coordinat...
