Generalization of an As/rs

چکیده
A model of an Automated Storage and Retrieval System built using the SIMAN/CINEMA simulation software is presented in this paper. A detailed description of the system is given. The modeling issues that are raised by the nature of the system and by the requirements of the analyses to be made are explained. As the model involves both SIMAN and FORTRAN code, a description of various tasks accomplished by both parts is provided. Furthermore, a brief discussion of some of the results obtained by using the model is presented. Conclusions of the study regarding a generic approach to modeling similar systems are given at the end of the paper.

Retrieval–travel-time model for free-fall-flow-rack automated storage and retrieval system
Automated storage and retrieval systems (AS/RSs) are material handling systems that are frequently used in manufacturing and distribution centers. The modelling of the retrieval–travel time of an AS/RS (expected product delivery time) is practically important, because it allows us to evaluate and improve the system throughput. The free-fall-flow-rack AS/RS has emerged as a new technology for dr...
متن کاملA Strong Regular Relation on ?-Semihyperrings
The concept of algebraic hyperstructures introduced by Marty as a generalization of ordinary algebraic structures. In an ordinary algebraic structure, the composition of two elements is an element, while in an algebraic hyperstructure, the composition of two elements is a set. The concept of ?-semihyperrings is a generalization of semirings, a generalization of semihyperrings and a generalizat...

متن کاملThe dimension of subcode-subfields of shortened generalized Reed-Solomon codes
Reed-Solomon (RS) codes are among the most ubiquitous codes due to their good parameters as well as efficient encoding and decoding procedures. However, RS codes suffer from having a fixed length. In many applications where the length is static, the appropriate length can be obtained by an RS code by shortening or puncturing. Generalized Reed-Solomon (GRS) codes are a generalization of RS codes...

Dynamic network data envelopment analysis (DNDEA) has attracted a lot of attention in recent years. On one hand the available models in DNDEA evaluating the performance of a DMU with interrelated processes during specified multiple periods but on the other hand they can only measure the efficiency of dynamic network structure when a supply chain structure present. For example, in the banking in...
