Batches processing modes for manual operating system considering learning rate and handling time

On the basis of considering the employee learning rate and handling time in-between processes, this paper researches batches processing modes for manual operating system. We give three formulae about production cycle of a batch of parts for the group-processing mode and production-line modes with method of strict theoretical proof. In the given example case, we analyze and compare the three operation modes, and have got the results that the group-processing mode has the shortest production cycle. Meanwhile, we establish the time model of the processing and handling about each production process and transport process, analyze the number of parts for each handling process, and design a global optimization algorithm about the number of handling equipment for the transport process. The decision-makers can effectively arrange processing and handling tasks of a batch of parts by using the information which can be got from the time model and the number of handling equipment and solve the minimum quantity of the handling equipment by the global optimization algorithm which is firstly introduced in the paper.
