Research on Model and Efficiency of Manual Order Picking Service System

Manual order picking system can be regarded as a stochastic service system when we consider order arrival as system input and order picking as service. Enhancing its efficiency is very import for increasing client's satisfaction. Basing on the picking route stochastic model under sorted storage S-type picking condition, the stochastic service time distribution is deduced, and then corresponding efficiency indicators of system are calculated. The research of this paper is able to provide reference for the estimation picking time and waiting time.
