Computer Storage and Retrieval System for Two-Dimensional Outlines

Computer storage and retrieval system for two-dimensional outlines.

A new operational system designed at the Center for Human Growth and Development provides computer acquisition, storage, and retrieval of high-resolution images of cephalometiic tracings. The data structure is such that, on command, any defined distance, angle, area, or perimeter may be easily calculated by computer. Complete tracings, or portions, may be computer-displayed, superimposed, scale...

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...

An Integrated Model for Storage Location Assignment and Storage/Retrieval Scheduling in AS/RS system

An integrated optimization framework, including location assignment under grouping class-based storage policy and schedule of dual shuttle cranes, is offered by presenting a new optimization programming model. The objective functions, which are considered at this level, are the minimization of total costs and energy consumption. Scheduling of dual shuttle cranes among specified locations, which...

Reducing Retrieval Time in Automated Storage and Retrieval System with a Gravitational Conveyor Based on Multi-Agent Systems

The main objective of this study is to reduce the retrieval time of a list of products by choosing the best combination of storage and retrieval rules at any time. This is why we start by implementing some storage rules in an Automated Storage/Retrieval System (Automated Storage and Retrieval System: AS/RS) fitted with a gravity conveyor while some of these rules are dedicated to storage and ot...
