This paper considers automated storage and retrieval systems with double shuttle. We developed the expected travel time model based on the first come first served rule. An heuristic procedure by retrieval order sequencing was presented which aimed to improve the operation efficiency laking advantage of "No cost zone". Through sensitivity study, we evaluated the performance of the double shuttle system working on the four command cycle.
