Description
Summary:Multi aisle automated storage and retrieval systems correspond to multiple picking aisles served by a single storage and retrieval machine. We use this system for saving the initial investment costs due to single aisle systems. The objective of the presented study is to develop analytical travel time models for multi aisle automated storage and retrieval systems considering the operating characteristics of the storage and retrieval machine. Acceleration and deceleration of the storage and retrieval machine is considered in this paper instead of uniform speed, and there are curve channels in the warehouse. Based on the above hypothesis, the time function and distance function are studied in this paper. The distribution function of the distance and time is given. On this basis, the expected travel time of the automated storage and retrieval system is studied. Finally, a numerical example is given. The results show that proposed analytical travel time models perform satisfactory according to the results and could be very useful tools for designing of multi aisle automated storage and retrieval systems in real-world applications.
