UNDERSTANDING OF CONTINOUS MODEL AND DISCRETE MODEL FOR SINGLE TIME IN MULTI AUTOMATIC STORAGE AND RETRIEVAL SYSTEM USING BASIC CLASS : A REVIEW

Abstract

This journal review aims to better understand the automation of control systems, especially regarding discrete and continuous data. Begin with interest in discusses storage assignment problems in automated storage and retrieval (AS / RS) systems, and more specifically class-based storage in multi-aisle AS / RS. In the first part, we develop a sustainable approach. The latter is an analytical approach based on a continuous approach of multiple discrete distributions that models the precise horizontal and vertical motion of the S / R machines in each class A, B, and C. Furthermore, the proposed model is validated by comparing it with the discrete model. For this, we have studied several configurations to compare the results given by the discrete model and the continuous model. Finally, the results obtained show that these two models are very close to each other. This is expected because the expression developed is a continuous estimate of discrete data. This journal review aims to better understand the automation of control systems, especially regarding discrete and continuous data.
