In this paper, an approach using the concept of genetic algorithms is proposed as a powerful but simple means of scheduling the manufacturing operations of a virtual cellular manufacturing system (VCMS). A mathematical model is developed to describe the characteristics of a VCMS, which includes the constraints related to the delivery due dates of the various products and the maximum capacities of...
A 2.2 kJ repetitive plasma focus device (DPF-2.2) as a continuous pulsed neutron source is presented. Time integrated and time resolved neutron diagnostic techniques were used to investigate the characteristics of the neutron emission at repetitive-rate as one shot per minute. The average neutron yield per shot of (5.14±3.02)×107 and the maximum yield of 2.0×108 were obtained at the optimum deuterium...
A new kind of automatic balancing system is presented with the electromagnetic balancing regulator. The system provides a vibration feedback and a correction mass position feedback, which results in the adoption of a new balancing method. The method first obtains the influence coefficients and unbalance vector of the rotor system, then calculates the optimum positions of the correction masses and...
