In the job-shop scheduling field, timely and proper updating of original strategy is an effective way to avoid negative impact disturbances on manufacturing. this paper, a pure reactive method for proposed deal with disturbance uncertainty arrival new jobs in job shop. The implementation process as follows: combine data mining, discrete event simulation, dispatching rules (DRs), take makespan machine utilization criteria, divide manufacturing system production period into multiple...
In this paper, an electro-hydraulic servo resonance technology is proposed to meet the loading requirements of a high-frequency sound fatigue test for large tonnage. First all, we analyze static and dynamic structure vibration establish equation system. Additionally, modal characteristics system are analyzed by simulation, which verified feasibility resonant technology. Finally, influence various factors such as sample stiffness, lead screw class II spring weight mass, lower beam upper mass...
Abstract For the large tonnage high-frequency resonance fatigue test loading requirements, an electro-hydraulic servo control strategy is proposed. The structure and system principle are analyzed. based on functions of sinusoidal vibration signal sweeping, decomposition, alternating load loading, mean-value etc. circuit design verified by using simulation analysis methods. proposed technology realizes resonant broadens capacity, provides a theoretical basis for research development loud device.
Owing to the randomness of job release time, it is not possible obtain all information in real time during operation a manufacturing system. Generating suitable scheduling strategy at correct moment focus addressing this disturbance. In study, flow system was used as criterion for evaluating performance strategy. Subsequently, model constructed selecting optimal dispatching rule (DR) actively change strategies production process. The DR included an initial and evaluation model. outputs with...
