The content of this thesis draws heavily on work completed during a 6.5 month MIT Leaders for Manufacturing (LFM) internship at Dell Corporation's personal computer manufacturing facility in Lebanon, Tennessee (EG1) from June 2004 to December 2004. This work relates primarily to efforts to analyze and improve the throughput of the Automated Storage and Retrieval System (ASRS) in that factory. Wherever possible, the thesis abstracts from the EG1 factory case study to provide lessons for improving the throughput of ASRSs and accumulative manufacturing systems in general. In addition to this core of the thesis, specific implementation challenges encountered during the EG 1 case study are addressed. Finally, general cultural observations about Dell's manufacturing environment are discussed. The author believes the two most unique aspects of this work are the Crane Frontier framework developed for analyzing ASRS throughput (Section 2.6) and the range and taxonomy of ASRS throughput improvement solutions (Chapter 3).

Full textWith technology advancing, more and more people turn to the World Wide Web to conduct business. This may include buying and selling on the Web, advertising and monitoring of business activities. There is a big need for software and systems that enable remote monitoring and controlling of business activities. The Mechatronics Research Group of the Faculty of Engineering, Information and Communication Technology at the Central University of Technology, Free State, has identified a similar need. This research group has created an Automated Manufacturing System around which research topics revolve. They want to monitor this Automated Manufacturing System from remote locations like their offices or, if possible, from home. The Remote Information Management (RIM) System was developed, using the Rapid Application Development (RAD) Methodology. The reasons why this methodology was used, is because it is the best to use in a changing environment, when the system needs to be developed very quickly and when most of the data is already available. This is a good description of the Automated Manufacturing System’s environment. The RAD methodology consists of four stages: Requirements Planning, User Design, Rapid Construction and Transition. Project Management is used throughout these stages to ensure that the project goes according to plan. Development of the RIM system went through all four stages and project management was applied. The final system consisted of a Web Page with Web Camera views of the Automated Manufacturing System. The application that was developed using National Instruments LabVIEW, Microsoft Visual C++, and Microsoft Excel, is embedded in this Web Page. This application is called a Virtual Instrument (VI). The VI shows real-time data from the Automated Manufacturing System. Control over the VI can be granted and will allow the remote user to create reports on how many different products was produced and system downtimes. A system like the RIM System has advantages in the business world. It can enable telecommuting and will allow employees and managers to monitor (and even control) manufacturing systems, or any system connected to a PLC, from remote locations.

Full textfirmware and computer software are developed. These two boards communicate with computer one at a time. Some AS/RS related control rules are implemented at the control software. According to these rules the control software assigns tasks to the related board. Also the control software records necessary information in order to measure the performance of the AS/RS. Several control rules as storage assignment, dwell point and sequencing of storage and retrieval order rules are applicable to the AS/RS without need for low level programming. Because of the physical limitation, batching rules cannot be applied to the current system. Also a graphical user interface is developed for using the system easily and observing the real time status of the system equipments. Two experiments are designed and run in order to show flexibility of the control system. Different control rules applied to each of the experiment. Experiment results put forth the control system was quite successful in meeting the objectives.

Full textThe main aim of this research was to automate student attendance registration, thereby reducing human involvement in the whole process. This was made possible using Radio Frequency Identification (RFID) technology. The Central University of Technology uses student cards that are compatible for use with RFID technology. As a result, no initial investment (except for the existing personal computer’s and the constructed RFID reader) in infrastructure was required for this project. The basic working of the project was as follows. The students belonging to a specific class had their vital educational data (Student number, Name) entered into a database table at the time of registration. A student card containing a serial number, with reference to the data contained in the database table, was given to the students after registration. The students walk into their respective classes and scan their student cards with the RFID reader. The serial number stored in the student card is transferred to the reader and from there wirelessly to the main server using ZigBee technology. In the main server, using Java programming language, the card serial number is sent to the Integrated Development Environment (IDE). In this project the Netbeans IDE (Java platform) was used. The Netbeans IDE is connected to the Apache Derby database using Java Database Connector (JDBC), so the serial number (which is referenced to the educational data of the students) from the student card is automatically compared with the original database created at the time of registration. Once a match is confirmed between the two entries, the data is entered into a separate database table which serves as the basic attendance sheet for a specific day.

Full textEsta tese apresenta um método para a extração de regiões de interesse (ROIs) de imagens. No contexto deste trabalho, ROIs são definidas como os objetos semânticos que se destacam em uma imagem, podendo apresentar qualquer tamanho ou localização. O novo método baseia-se em modelos computacionais de atenção visual (VA), opera de forma completamente bottom-up, não supervisionada e não apresenta restrições com relação à categoria da imagem de entrada. Os elementos centrais da arquitetura são os modelos de VA propostos por Itti-Koch-Niebur e Stentiford. O modelo de Itti-Koch-Niebur considera as características de cor, intensidade e orientação da imagem e apresenta uma resposta na forma de coordenadas, correspondentes aos pontos de atenção (POAs) da imagem. O modelo Stentiford considera apenas as características de cor e apresenta a resposta na forma de áreas de atenção na imagem (AOAs). Na arquitetura proposta, a combinação de POAs e AOAs permite a obtenção dos contornos das ROIs. Duas implementações desta arquitetura, denominadas 'primeira versão' e 'versão melhorada' são apresentadas. A primeira versão utiliza principalmente operações tradicionais de morfologia matemática. Esta versão foi aplicada em dois sistemas de recuperação de imagens com base em regiões. No primeiro, as imagens são agrupadas de acordo com as ROIs, ao invés das características globais da imagem. O resultado são grupos de imagens mais significativos semanticamente, uma vez que o critério utilizado são os objetos da mesma categoria contidos nas imagens. No segundo sistema, á apresentada uma combinação da busca de imagens tradicional, baseada nas características globais da imagem, com a busca de imagens baseada em regiões. Ainda neste sistema, as buscas são especificadas através de mais de uma imagem exemplo. Na versão melhorada da arquitetura, os estágios principais são uma análise de coerência espacial entre as representações de ambos modelos de VA e uma representação multi-escala das AOAs. Se comparada à primeira versão, esta apresenta maior versatilidade, especialmente com relação aos tamanhos das ROIs presentes nas imagens. A versão melhorada foi avaliada diretamente, com uma ampla variedade de imagens diferentes bancos de imagens públicos, com padrões-ouro na forma de bounding boxes e de contornos reais dos objetos. As métricas utilizadas na avaliação foram presision, recall, F1 e area of overlap. Os resultados finais são excelentes, considerando-se a abordagem exclusivamente bottom-up e não-supervisionada do método.
This thesis presents a method for the extraction of regions of interest (ROIs) from images. By ROIs we mean the most prominent semantic objects in the images, of any size and located at any position in the image. The novel method is based on computational models of visual attention (VA), operates under a completely bottom-up and unsupervised way and does not present con-straints in the category of the input images. At the core of the architecture is de model VA proposed by Itti, Koch and Niebur and the one proposed by Stentiford. The first model takes into account color, intensity, and orientation features and provides coordinates corresponding to the points of attention (POAs) in the image. The second model considers color features and provides rough areas of attention (AOAs) in the image. In the proposed architecture, the POAs and AOAs are combined to establish the contours of the ROIs. Two implementations of this architecture are presented, namely 'first version' and 'improved version'. The first version mainly on traditional morphological operations and was applied in two novel region-based image retrieval systems. In the first one, images are clustered on the basis of the ROIs, instead of the global characteristics of the image. This provides a meaningful organization of the database images, since the output clusters tend to contain objects belonging to the same category. In the second system, we present a combination of the traditional global-based with region-based image retrieval under a multiple-example query scheme. In the improved version of the architecture, the main stages are a spatial coherence analysis between both VA models and a multiscale representation of the AOAs. Comparing to the first one, the improved version presents more versatility, mainly in terms of the size of the extracted ROIs. The improved version was directly evaluated for a wide variety of images from different publicly available databases, with ground truth in the form of bounding boxes and true object contours. The performance measures used were precision, recall, F1 and area overlap. Experimental results are of very high quality, particularly if one takes into account the bottom-up and unsupervised nature of the approach.

In the face of e-commerce growth and rising customer delivery expectations, companies must adapt to meet shorter contract shipping requirements with existing infrastructures. The "Amazon effect", an evolution resulting in increased online shopping and direct-to-consumer order fulfillment, is reverberating through the retail industry and requiring manufacturers to evaluate their existing supply chain networks to meet two- and one-day shipping from their distribution centers (DC). This thesis evaluates speed and execution improvements using automated storage and retrieval systems (ASRS) in DCs. Adopting ASRS can provide the essential capability upgrades to reduce material processing time and meet direct-to-consumer deliveries. The ASRS analysis reviews current DC metrics, future throughput and inventory requirements, comparisons of ASRS technologies utilized today, expected impact of ASRS inside of an existing DC, and sizing and selection of an ASRS. Analysis of the DC evaluated showed that the primary cause of delays in shipping time was due to high variability in task completion time, rather than a high average completion time, causing extended wait times to propagate throughout the DC. While methods to reduce task time variation can be implemented, a warehouse logic upgrade would allow for real-time sequencing to get products shipped in the correct order based on factors like shipping method, customer, or priority. Implementation of ASRS in the DC evaluated could decrease processing time in storage and retrieval by 67% and total processing time through the DC by 37% due to ideal sequencing, diminished downstream variability, and reduced work in progress. The payback period for ASRS is projected to be 4 to 5 years..

Automatic storage of relevant studies have been developed, including design principles of automatic storage, automatic storage structure of the classification of the operation of automatic storage systemic flow analysis, automatic storage, such as access to local access logic, and comparison, for the operation of the Automated Storage and Retrieval Management seldom explored. Automated Storage and Retrieval operations from time to ship about the proportion of the entire warehousing operation time of about 30% ~ 40% efficiency of the implementation of warehouse storage operations to be automated so that the effective operation of storage as the first priority. A company warehousing operations, including production, order processing, automated warehousing operation get access to machines, as well as cargo handling operations and effective co-ordination between them, or will have excessive or unnecessary bottlenecks in operations, not only affects the logistics center picking time, and the overall service operation caused delay, unnecessary costs arising. Therefore, in order to automatically analyze the establishment of a correct storage and picking operations more efficient management, automatic storage for the entire impact of the implementation will not be quite efficient. Therefore, the depth will be able to automatic storage and day-to-day operation of what happened on controlling abnormal situation, analyze the risks and possible preventive measures and even set up more efficient processes in order to effectively enhance the storage of Automated Storage and Retrieval Systems Operations Management is very worthy of study issue. The main purpose of this study was to explore the failure of the automatic storage system maintenance problems.

Warehouse industries and modern factories are now dominated by crane-based Automated Storage and Retrieval Systems (AS/RS's) where aisle captive cranes provide more efficient movement patterns owing to simultaneously horizontal and vertical movement. However, system performance of AS/RS’s is not well discussed analytically and efficiently. This thesis proposes computationally efficient performance evaluation models for AS/RS’s under stochastic demand. Based on the assumptions of First-Come-First-Serve, random storage and a particular dwell point policy, storage/retrieval (S/R) machine travel time and the probability distribution for four travel scenarios are formulated and used to generate expected transaction service times. System performance including transaction waiting time and S/R machine utilization is the key to determine if the transaction demand is met. The proposed models provide prediction of system performance based on rack sizes, S/R machine travel velocity and transaction demand rates. They can be illustrated in the design and evaluation for an actual system installation.

Automated Storage and Retrieval Systems (AS/RS) utilize high density storage capacities as well as elevated rack structures, which challenge the feasibility and validity of active fire regulations. Recently in Japan, there were two occurrences of major fire accidents in the logistics industry that had AS/RS. However, it is noted that the domestic standards set for automatic sprinkler systems in these locations are only stated in Article 17 of “Standard for Installation of Fire Safety Equipments Based on Use and Occupancy”, and the fact that many of the domestic standards are based off of Japanese regulations, it shows that the effectiveness of sprinklers for AS/RS above 30 meters high need to be reevaluated. This research focused on literature collection and field surveys of AS/RS, and analyzed classification of goods, setup specifications of automatic sprinkler equipment, and also the current designs within the industry. FDS was then used to simulated fires within AS/RS while field experiments were conducted to assess the fire extinguishing performance of storage rack sprinklers. FDS simulation results showed that when sprinklers were located directly above the goods, normal fires (Class II) could be extinguished, while the growth of plastic fires (Group A) could be slowed. Field experiments results showed that when sprinklers with a K value of 114 LPM/bar0.5 were set directly above the goods, a discharge pressure of 1 kgf/cm2 could extinguish the fire; but if the sprinklers were placed between double row racks, the discharge pressure would need to be 2 kgf/cm2 for it to be effective. Therefore, this research recommends that the minimum required discharge pressure for sprinklers be 2 kgf/cm2 for the effective suppression of fire growth.

Programmable Logic Controllers (PLCs) are the most common controller units which is used in automated storage/retrieval systems (AS/RS) presently. These PLCs are then liked to the decision making unit and or the management unit under the control of main computer for accomplishing the system integration. Since the AS/RS functional requirements, such as the high speed and accurate positioning of the S/R machine, are gaining in future, the current PLCs control structures may no longer adapt the complicate environments. The advantage characteristics in AS/RS management system for distributed processing which applies the system of Fuzzy-Integrated Programmable Logic Control (FPLC) and assimilates the control logic of software as well as management rules are the problem solver and the major consideration in this paper under this distributed processing structure, the main computer is served as a coordinating center that distributing the processed motion command to each auxiliary or subauxiliary node through the powerful communication network. And then each auxiliary node is setting accomplish the commands by its hard- and or soft-ware functions. This distributed processing makes it much easier in modular design. Moreover, it reduces the difficulties in modification and or extending. The user friendly interface makes the integration of the distributed processing and management decision system more easy to use. Furthermore, it may also monitor the opoeration during functioning.
