Abstract:

Thesis (M. Eng.)--Massachusetts Institute of Technology, Dept. of Mechanical Engineering, 2007.<br>Includes bibliographical references (p. 66).<br>TCG is a multinational pharmaceutical company. As part of its drive to stay lean and competitive, TCG hopes to effectively maximize its capital assets by reducing warehouse inventory. This thesis aims to reduce the inventory of intermediate products through the use of fixed demand rate production planning and inventory controls. The production planning model attempts to derive the optimal production cycle time based on demand rates, production rates and setup times to prevent stock outs. The optimal cycle time should provide the optimal inventory levels for the intermediate products. The production planning model stabilizes the fluctuations in inventory levels and outperforms TCG's production plan in 2008 by 115 pallet spaces. With an order-up-to policy, the inventory level is capped at a maximum level, preventing uncontrolled accumulation of inventory of the intermediate products. This will prevent stock outs and stabilize inventory levels. Using an order-up-to policy to minimize the inventory, a reduction of up to 1.8% can be achieved.<br>by Yixiong Kok.<br>M.Eng.

Abstract:

Thesis (M. Eng.)--Massachusetts Institute of Technology, Dept. of Mechanical Engineering, 2007.<br>Includes bibliographical references (p. 77).<br>This thesis is the result of a three month internship at TCG Pharmaceuticals, Singapore. With the worldwide initiative of lean in TCG, it has implemented the TCG Production System which finds its roots in the famous Toyota Production System. The recognition of the importance of reducing the waste of inventory by TCG is the main motivational force for this internship. This thesis documents the inventory levels of the finished goods in the current production scenario and also analyzes the inventory levels for the future as the production of a new product is aimed to be launched this year. The main purpose of this thesis is to suggest ways to better manage the finished goods inventory at TCG. The future states are modeled using a single stage multi product system and various scenarios are developed. A comparison is made between the TCG's planned production schedule and the production schedules developed based on the different scenarios generated using the model. The performance is measured in terms of the space that is needed in each case to hold the inventory.<br>by Sumit Gupta.<br>M.Eng.

Abstract:

The study aims at investigating how revenue management techniques can be applied in industries which offer multiple products. Most of the companies nowadays trend to produce multiperoducts and they try to find the best method of selling. Therefore, revenue management can be considered as a new direction which should be developed for these firms. In this study, multi-product firms are mainly referred as firms offering a bundle of products or substitute products. In this regard, models and techniques applied in multiproduct firms are discussed and it is tried to provide basic models to better understand the problems, variables, customer choice models and constraints. The main methodology in this study is literature review. In order to carry out the research first revenue management applications and techniques are discussed to find a fit to this kind of industries. The main findings of this study are (1) identifying and analyzing the most important factors affecting decision making regarding managing of bundling and substitute products and ultimately total revenue of multiproduct firms. (2) Summarizing the results and knowledge obtained from various studies within fields of bundling and substitute products. (3) Discussing the possibility of applying different revenue management techniques to these fields. (4) Identifying potentials and new directions for future study with respect to both revenue management techniques and multiproduct firms.

Abstract:

<p>Today many companies face problems with inventory management. The importance of adequate inventory management has become more evident, while organizations try to reduce their costs and increase their service level.</p><p>This master thesis was conducted at VSM Group AB in Huskvarna, which is a manufacturer that produces and delivers sewing machines to a worldwide market. VSM Group AB has problems with the management and the refilling of the work-in-process (WIP) inventories and also with lack of information about component balance and location in the production and material planning system.</p><p>Therefore, the purpose of the thesis was to improve the control of the WIP inventories and the information about the components in the production and material planning system. In order to achieve the purpose, interviews and observations were performed, theories in inventory management were reviewed and the production process was studied.</p><p>Afterwards solutions for improvements were proposed. To solve the management and refilling problem, a kanban ordering system was proposed, which would use kanban cards to order components from the storages to the WIP inventories. To develop the component information displayed in the production and material planning system, an additional feature was proposed to the system. So instead of showing one inventory balance for each component, the system would display balances for three different places in the factory: the goods arrival and quality control area, the storage and the production.</p><p>The proposed solutions can provide several benefits to the company. The kanban ordering system can increase the material handlers’ efficiency, set a standard refilling quantity and be a tool for reducing the WIP inventory levels. The more detailed information in the production and material planning system can improve the decision making for the purchasers and planners and give the ability to measure the flow and level of material inside the factory.</p><p>These solutions will provide a more appropriate inventory management to the company, with better control of the components and improved information quality.</p>

Neste contexto a otimização e racionalização da gestão de estoques é uma grande oportunidade para estas empresas conquistarem estes objetivos. Para a realização desta pesquisa optou-se pela metodologia de estudo de casos múltiplos (dois casos), para atender o objetivo de analisar a gestão de estoques em duas empresas do setor gráfico localizadas na região de Bauru, na qual uma adota o sistema produtivo Engineering-To-Order (ETO) e a outra o sistema produtivo Make-To-Stock (MTS). O qual foi alcançado por meio da triangulação dos meios de coleta de dados, ou seja, entrevista semi-estruturada, análise documental e observação in-loco e estes tiveram como embasamento o referencial teórico. Por meio da triangulação das informações obtidas durante a coleta de dados, pôde-se elaborar a descrição da gestão de estoques e do sistema produtivo adotado em cada uma das empresas apresentadas nos estudos de caso e a análise cruzada. Após estes procedimentos foi elaborada a análise da influência do sistema produtivo sobre a gestão de estoques, no qual foram analisados os seguintes itens: produção, previsão de demanda, sazonalidade, layout, gestão de estoques, setup, logística de suprimentos e logística de distribuição.<br>Industrial organizations are adopting productive models that prioritize the reduction of costs and increase the quality of their processes and products. In this context the optimization and streamlining the inventory management is a great opportunity for these companies conquer these goals. To achieve this research methodology was chosen for the study of multiple cases (two cases), to meet to evaluate the inventory management in two companies in the sector chart located in the region of Bauru, in which one adopts the production system. Which was achieved by means of triangulation of data collection, i.e., semi-structured interviews, document analysis and observation in loco and they were light as the theoretical framework. Through triangulation of information obtained during data collection, it was possible to develop a descritption of the inventory management and the production system used in each of the companies presented in case studies and crossexamination. After these procedures were developed to analyze the influence of the production system on the inventory management, which were analyzed in the following: production, estimates of demand, seasonality, layout, inventory management, setup, logistics supplies and logistics of distribution. While reviewing the analysis of the influence of the production system on the management of inventories could be observed some differences in relation to the literature, they are: logistics supply, distribution, inventory management, production systems Make-To-Stock and Engineering-To-Order.

Abstract:

Today’s e-Commerce systems are applying pressure on the manufacturing industry. Shorter lead times, smaller production runs, just-in-time inventory and build-to-order are all manufacturing operations’ nightmares. Worse, with ERP, CRM, APS and SCM, each application provides significant content but it is very difficult to make them all work together. The Manufacturing Execution System is the glue that turns all the pieces of the puzzle into one solid solution. Manufacturing Execution System accomplishes this by becoming the source of real-time production/fulfillment data and the central data source. Manufacturing Execution System applications effectively fall into the following areas: _ Enterprise system integration _ Production tracking w/genealogy _ Real-time Inventory Management _ Manufacturing operations management * (ERP - enterprise resource management, CRM - customer relationship management, APS - advanced planning and scheduling, SCM - supply chain management).

Abstract:

Due to globalization, there is tremendous demand on Indian companies to lower costs, enlarge product assortment, improve product quality, and provide reliable delivery dates through effective and efficient coordination of production and distribution activities. To achieve these conflicting goals, companies must constantly re-engineer or change their business practices and employ information systems like Enterprise Resource Planning (ERP). However, implementing ERP system is a difficult and high cost proposition. There are mixed results of success and failure in different companies. With a survey of manufacturing companies in India and subsequent detailed case study in one ERP implemented company, this study analyzes various parameters of ERP implementations with factor analysis and logit regression analysis. It is revealed that with clear goals of ERP implementation and proper ERP software selection, the companies are benefited in reducing inventory, improving customer service and other intangible benefits. The top management support, strong and meaningful training program are found the enabling factors of its success. It is argued that this study and ERP implementation model proposed in this paper is valuable to researchers and practitioners interested in implementing ERP system. The findings will also be helpful in extracting the better results from ERP implementation.

Abstract:

Two historic waste packages on the Sellafield Site with potentially high fissile content were destined for re-packaging. Prior to relocation and subsequent breakdown, each item underwent a campaign of non-destructive assay. The aim of the assay was to gather information that would assist with the production of a safety case. The assay work consisted of: conventional x-ray radiography to determine the identity of the contents; gamma imaging and three-dimensional tomographic re-construction to determine the location of the gamma emitting material; and neutron coincidence counting coupled with gamma spectrometry to assign a fissile mass. Most items on the Sellafield Site that undergo non-destructive assay normally remain intact or are re-packaged with minimal interference of the content. However, in this instance each item was dismantled and the fissile material recovered. This paper provides a comparison of the measured results with the actual results for each technique. The x-ray radiographic information was used to construct a three dimensional representation of the contents of each item. This information was useful in identifying the plant items contained within. The results were discussed with plant operators who were familiar with the historic plant. The operators were able to identify areas of likely accumulations of fissile material. The two-dimensional gamma survey and subsequent threedimensional re-construction revealed the location of the gamma emitting materials within the packages. It was assumed that areas of increased gamma activity indicated areas of increased fissile mass. The neutron coincidence counting, gamma measurements and subsequent modelling provided an estimate of fissile mass for each item. The fissile mass estimate is an essential component of the safety case planning. However, it does not provide all of the information required to plan an ALARP breakdown strategy. The combination of the information gathered through assay was essential to construct a safety case that considered: transport requirements; criticality risk; dose to operator and breakdown methodology. Subsequent studies suggest that improved combination of the data acquired from the assay programme and more post-assay discussion of the specific issues and implications between the various stakeholder groups (e.g. assay engineers and safety case authors) may have led to a fissile mass result with lower uncertainties, which given a more favourable example would have resulted in a significant cost savings through reduced criticality assessment burden and mitigation actions and reduced security control.

Abstract:

The Government of Iraq (GOI) has undertaken efforts to decommission and dismantle former nuclear facilities. The GOI has only preliminary information on some of the former nuclear facilities. This paper will highlight the challenges involved in conducting inspections of the outlying former nuclear facilities in Iraq and present a brief summary of the results of those inspections. The facilities discussed in this paper are located at various sites throughout Iraq, from locations close to Baghdad to those in the north and far western desert areas. Some of the facilities, such as those at the Al Tuwaitha Nuclear Research Center have been visited and characterized. Other facilities, including the following, have not been visited or thoroughly characterized. • Al Jesira, Uranium feed stock production facility; • Adaya, Burial location for contaminated equipment; • Djerf al Naddah, Spent fuel storage facility; • Rashdiya, Centrifuge development center; • Al Qa’im, Uranium (yellowcake) production facility. The visits were conducted to develop an inventory of the buildings/structures that need to be included in decommissioning/dismantlement efforts. The number of buildings, type of construction, size and general condition of the buildings were noted. In addition, attempts were made to determine contamination levels on surfaces, equipment, rubble, etc. This information will be used to support the Iraqi decommissioning and dismantlement project. Because the facilities are scattered throughout the country of Iraq, significant planning and coordination was required to ensure personnel security. Teams consisting of individuals from the Iraqi Ministry of Science and Technology (MoST) and Americans were under military escort when traveling to and visiting the sites. Because of the security issues, time on the ground at each site was limited. This paper will highlight the challenges involved in conducting the inspections of the outlying former nuclear facilities In Iraq and present a brief summary of the results of those inspections.

Abstract:

The nuclear installation decommissioning process is characterized by production of large amount of various radioactive and non-radioactive waste that has to be managed, taking into account its physical, chemical, toxic and radiological properties. Waste management is considered to be one of the key issues within the frame of the decommissioning process. During the decommissioning planning period, the scenarios covering possible routes of materials release into the environment and radioactive waste disposal, should be discussed and evaluated. Unconditional and conditional release to the environment, long-term storage at the nuclear site, near surface or deep geological disposal and relevant material management techniques for achieving the final status should be taken into account in the analysed scenarios. At the level of the final decommissioning plan, it is desirable to have the waste management scenario optimized for local specific facility conditions taking into account a national decommissioning background. The analytical methodology for the evaluation of decommissioning waste management scenarios, presented in the paper, is based on the materials and radioactivity flow modelling, which starts from waste generation activities like pre-dismantling decontamination, selected methods of dismantling, waste treatment and conditioning, up to materials release or conditioned radioactive waste disposal. The necessary input data for scenarios, e.g. nuclear installation inventory database (physical and radiological data), waste processing technologies parameters or material release and waste disposal limits, have to be considered. The analytical methodology principles are implemented into the standardised decommissioning parameters calculation code OMEGA, developed in the DECOM company. In the paper the examples of the methodology implementation for the scenarios optimization are presented and discussed.

Abstract:

Quyen Le, Deputy Director at ABC Textile and Dyeing Joint Venture Company (JVC), returned from a meeting with an Enterprise Resource Planning (ERP) service provider. Quyen was wondering which options of ERP implementation would be best suited to gain staff support and pre-pared the company for long term development. ABC had undergone considerable growth in recent years. Having become one of leading manufacturers of denim fabric in Vietnam market, the company was now facing some organizational challenges. To cope with pressing competition in local and overseas markets, ABC had needed to acquire internationally recognized certification for its quality control system and standardized manufacturing process. The company implemented a quality management process in order to achieve its goal of ISO9000:2008 certification. There was substantial additional paperwork to be handled with the new process. ABC currently used an outdated decentralized computing system in managing its denim manufacturing process. It was time-consuming and difficult to obtain timely and accurate production information—including material planning, production costing, machinery inventory, production reports—and difficult to share information among departments. Furthermore, over a hundred different reports for various stages of the denim manufacturing process were generated and handled by several departments. Lacking the technical knowledge to deal with complex technological context, Quyen considered outsourcing the implementation of an ERP system to ease the documentation tasks required by the ISO 9000:2008, and to manage more effectively the denim manufacturing and to streamline the reporting system. Facing concerns and criticisms from staff during the implementation of the ISO 9000:2008 quality management process due to its complex, time-consuming documentation requirement and added workload with no immediate benefits, Quyen was facing a tough decision whether to move forward with implementing an ERP system that promised another tough challenge to get the sup-port from staff and required necessary organizational changes to create business value from the information technology (IT) investment. ABC Textile and Dyeing JVC (ABC) was part of a textile industry that represented an important component of the global and local economies.

Abstract:

The paper describes different methodologies and tools developed in-house by Tractebel Engineering to facilitate the engineering works to be carried out especially in the frame of decommissioning projects. Three examples of tools with their corresponding results are presented: - The LLWAA-DECOM code, a software developed for the radiological characterization of contaminated systems and equipment. The code constitutes a specific module of more general software that was originally developed to characterize radioactive waste streams in order to be able to declare the radiological inventory of critical nuclides, in particular difficult-to-measure radionuclides, to the Authorities. In the case of LLWAA-DECOM, deposited activities inside contaminated equipment (piping, tanks, heat exchangers ...) and scaling factors between nuclides, at any given time of the decommissioning time schedule, are calculated on the basis of physical characteristics of the systems and of operational parameters of the nuclear power plant. This methodology was applied to assess decommissioning costs of Belgian NPPs, to characterize the primary system of Trino NPP in Italy, to characterize the equipment of miscellaneous circuits of Ignalina NPP and of Kozloduy unit 1 and, to calculate remaining dose rates around equipment in the frame of the preparation of decommissioning activities; - The VISIMODELLER tool, a user friendly CAD interface developed to ease the introduction of lay-out areas in a software named VISIPLAN. VISIPLAN is a 3D dose rate assessment tool for ALARA work planning, developed by the Belgian Nuclear Research Centre SCK·CEN. Both softwares were used for projects such as the steam generators replacements in Belgian NPPs or the preparation of the decommissioning of units 1&2 of Kozloduy NPP; - The DBS software, a software developed to manage the different kinds of activities that are part of the general time schedule of a decommissioning project. For each activity, when relevant, algorithms allow to estimate, on the basis of local inputs, radiological exposures of the operators (collective and individual doses), production of primary, secondary and tertiary waste and their characterization, production of conditioned waste, release of effluents, ... and enable the calculation and the presentation (histograms) of the global results for all activities together. An example of application in the frame of the Ignalina decommissioning project is given.

Abstract:

Currently, pipeline is the most effective way to transport large-volume products over long distance. To effectively satisfy market demands for multiple refined products by delivery due dates, the multi-product pipeline network usually transports several refined products in sequence from refineries to certain destinations. The integrated scheduling of multi-product pipeline network, including inventory management, transport routes planning, batch sequence, batch volume, et al., is one of the most strategic problems due to its large-scale, complexity as well as economic significance. This subject has been widely studied during the last decade. However, most researches focus on large-size scheduling models whose computational efficiency greatly decreases for a complex pipeline network or a long time horizon. Aiming at this problem, the paper develops an efficient decomposition approach, which is composed of two mixed integer linear programming (MILP) models. The first model divides the entire time horizon into several intervals according to delivery due dates and optimizes the transport routes and total transport volume during each interval with considering market demand, production campaigns and inventory limits. Then the solved results are used by the second model which sets the objective function as the membership function based on fuzzy delivery due dates. Besides, a series of operational constraints are also considered in the second model to obtain the optimal batch sequence, batch volume, delivery volume and delivery time in each node. Finally, the proposed approach is applied to a Chinese real-world pipeline network that includes 5 complex multi-product pipelines associated with 6 refineries and 2 depots. The results demonstrate that the proposed approach can provide a guideline for long-term pipeline network scheduling with delivery due dates.

Abstract:

A fundamental responsibility of the National Park Service (NPS) is to ensure that park resources are preserved, protected, and managed in consideration of the resources themselves and for the benefit and enjoyment by the public. Through the inventory, monitoring, and study of park resources, we gain a greater understanding of the scope, significance, distribution, and management issues associated with these resources and their use. This baseline of natural resource information is available to inform park managers, scientists, stakeholders, and the public about the conditions of these resources and the factors or activities which may threaten or influence their stability. There are several different categories of geologic or stratigraphic units (supergroup, group, formation, member, bed) which represent a hierarchical system of classification. The mapping of stratigraphic units involves the evaluation of lithologies, bedding properties, thickness, geographic distribution, and other factors. If a new mappable geologic unit is identified, it may be described and named through a rigorously defined process that is standardized and codified by the professional geologic community (North American Commission on Stratigraphic Nomenclature 2005). In most instances when a new geologic unit such as a formation is described and named in the scientific literature, a specific and well-exposed section of the unit is designated as the type section or type locality (see Definitions). The type section is an important reference section for a named geologic unit which presents a relatively complete and representative profile. The type or reference section is important both historically and scientifically, and should be protected and conserved for researchers to study and evaluate in the future. Therefore, this inventory of geologic type sections in NPS areas is an important effort in documenting these locations in order that NPS staff recognize and protect these areas for future studies. The documentation of all geologic type sections throughout the 423 units of the NPS is an ambitious undertaking. The strategy for this project is to select a subset of parks to begin research for the occurrence of geologic type sections within particular parks. The focus adopted for completing the baseline inventories throughout the NPS was centered on the 32 inventory and monitoring networks (I&M) established during the late 1990s. The I&M networks are clusters of parks within a defined geographic area based on the ecoregions of North America (Fenneman 1946; Bailey 1976; Omernik 1987). These networks share similar physical resources (geology, hydrology, climate), biological resources (flora, fauna), and ecological characteristics. Specialists familiar with the resources and ecological parameters of the network, and associated parks, work with park staff to support network level activities (inventory, monitoring, research, data management). Adopting a network-based approach to inventories worked well when the NPS undertook paleontological resource inventories for the 32 I&M networks. The network approach is also being applied to the inventory for the geologic type sections in the NPS. The planning team from the NPS Geologic Resources Division who proposed and designed this inventory selected the Greater Yellowstone Inventory and Monitoring Network (GRYN) as the pilot network for initiating this project. Through the research undertaken to identify the geologic type sections within the parks of the GRYN methodologies for data mining and reporting on these resources were established. Methodologies and reporting adopted for the GRYN have been used in the development of this type section inventory for the Klamath Inventory & Monitoring Network. The goal of this project is to consolidate information pertaining to geologic type sections which occur within NPS-administered areas, in order that this information is available throughout the NPS to inform park managers...

Abstract:

In 2015, the Natural Sounds and Night Skies Division (NSNSD) received a request to collect baseline acoustical data at Mesa Verde National Park (MEVE). Between July and August 2015, as well as February and March 2016, three acoustical monitoring systems were deployed throughout the park, however one site (MEVE002) stopped recording after a couple days during the summer due to wildlife interference. The goal of the study was to establish a baseline soundscape inventory of backcountry and frontcountry sites within the park. This inventory will be used to establish indicators and thresholds of soundscape quality that will support the park and NSNSD in developing a comprehensive approach to protecting the acoustic environment through soundscape management planning. Additionally, results of this study will help the park identify major sources of noise within the park, as well as provide a baseline understanding of the acoustical environment as a whole for use in potential future comparative studies. In this deployment, sound pressure level (SPL) was measured continuously every second by a calibrated sound level meter. Other equipment included an anemometer to collect wind speed and a digital audio recorder collecting continuous recordings to document sound sources. In this document, “sound pressure level” refers to broadband (12.5 Hz–20 kHz), A-weighted, 1-second time averaged sound level (LAeq, 1s), and hereafter referred to as “sound level.” Sound levels are measured on a logarithmic scale relative to the reference sound pressure for atmospheric sources, 20 μPa. The logarithmic scale is a useful way to express the wide range of sound pressures perceived by the human ear. Sound levels are reported in decibels (dB). A-weighting is applied to sound levels in order to account for the response of the human ear (Harris, 1998). To approximate human hearing sensitivity, A-weighting discounts sounds below 1 kHz and above 6 kHz. Trained technicians calculated time audible metrics after monitoring was complete. See Methods section for protocol details, equipment specifications, and metric calculations. Median existing (LA50) and natural ambient (LAnat) metrics are also reported for daytime (7:00–19:00) and nighttime (19:00–7:00). Prominent noise sources at the two backcountry sites (MEVE001 and MEVE002) included vehicles and aircraft, while building and vehicle predominated at the frontcountry site (MEVE003). Table 1 displays time audible values for each of these noise sources during the monitoring period, as well as ambient sound levels. In determining the current conditions of an acoustical environment, it is informative to examine how often sound levels exceed certain values. Table 2 reports the percent of time that measured levels at the three monitoring locations were above four key values.
