【Abstract】 An optimization strategy was proposed to maximize system availability under the constraint of total buffer capacity for the hybrid assembly line with the characteristics of multiple parallel devices, series of multiple stations and series and parallel production lines of multiple stripes. By analyzing the influence of the buffer status on the equipment of each station, the assembly line with buffer is equivalently processed. The performance of the equivalent equipment is described by the universal generating function, and the equivalent system is decomposed into several series subsystems and parallel subsystems. The series and parallel composite operators were introduced to solve the generation function of the whole line. Then, the mathematical model of buffer capacity and system availability is established. Finally, genetic simulated annealing algorithm is used to solve the optimal allocation of buffer. Taking the assembly line of infusion needle of a medical company as an example, the optimization results of the algorithm are evaluated and analyzed, and the feasibility of the scheme is verified.更多还原
