Chemical protective clothing is designed to protect the worker by providing a barrier between the individual and the contaminated environment. Unfortunately, the same equipment that is designed to help can often cause heat stress, reduced task efficiency, and reduced range-of-motion for the worker. Teams as well as individuals suffer from these effects resulting in difficulty communicating, increased task completion time, and reduced productivity. Studies investigating the effects of protective clothing generally focus on individuals; however, the military has produced research related to the effects of Mission Oriented Protective Posture (MOPP) on team performance outcomes in an attempt to understand how protective clothing might affect military teams and squads. Previous research has indicated a degradation of team performance as shown by increased task completion time; however, a comprehensive team performance measurement system studies not only the performance outcomes, but also the processes behind the outcomes. In order to provide a more complete understanding of the performance effects of protective clothing and equipment, this investigation focused on the effects of MOPP on the behavioral processes underlying team performance to include adaptability, communication, and coordination. It also attempted to validate previous studies on performance outcomes. Ten subjects formed five, two-member teams. Subjects were certified EMT's from local rescue squads and were required to perform CPR and spinal injury management (SIM). They performed each task twice-once in their duty uniform and once in MOPP level 4. Team performance was measured using the TARGETS methodology, and event-based team process performance measurement technique. A team performance index score (TPI) was calculated for each team for all four tasks and then used as the dependent measure for the analyses to compare team performance in a duty uniform versus performance in MOPP 4. Three hypotheses were tested in this study. They were as follows: team process performance will be degraded by MOPP, task completion time will increase as a result of wearing MOPP, and errors will increase as a result of wearing MOPP. Results of six primary analyses indicated that team process performance was not degraded and the number of errors did not increase when teams were wearing MOPP 4. Results did show, however, that task completion time was significantly longer when teams were wearing MOPP 4. The implications of these results are discussed in the thesis and design changes are put forth. / Master of Science

The management of quality is a consideration in all industries. The ISO 9000 standard defines a management system framework which includes the necessary and sufficient elements for the systematic management of quality. Some organizations experience positive results from implementing an ISO 9000 based quality management system while others do not. Given its widespread use and the economic implications of ineffective implementation, this study analyzes the implementation process steps, the performance of system elements after certification and organization performance metrics. The methodology combines publicly available financial data and survey results to characterize the determinants of success for ISO 9000 quality management system implementation.

Process planning is a task comprising a broad range of activities to design and develop an appropriate manufacturing process for producing a part. Interpretation of the part design, selection of manufacturing processes, definition of operations, operation sequences, machining datums, geometrical dimensions and tolerances are some common activities associated with the task. Process planning is also “the link between product design and manufacturing” with the supplementary commission to support design of competitive products. Process planning is of a complex and dynamic nature, often managed by a skilled person with few, or no, explicit methods to solve the task. The work is heuristic and the result is depending on personal experiences and decisions. Since decades, there have been plenty of attempts to develop systems for computer-aided process planning (CAPP). CAPP is still awaiting its breakthrough and one reason is the gap between the functionality of the CAPP systems and the industrial process planning practice. This thesis has an all-embracing aim of finding methods that cover essential activities for process planning, including abilities to predict the outcome of a proposed manufacturing process. This is realised by gathering supporting methods suitable to manage both qualitative and quantitative characterisation and analyses of a manufacturing process. The production research community has requested systematisation and deeper understanding of industrial process planning. This thesis contributes with a flow chart describing the process planning process (PPP), in consequence of the methodological studies. The flow chart includes process planning activities and information flows between these activities. The research has been performed in an industrial environment for high volume manufacturing of gear parts. Though gear manufacturing has many distinctive features, the methods and results presented in this thesis are generally applicable to precision manufacturing of many kinds of mechanical parts. / <p>QC 20140522</p>

Sustainability and green engineering are two main concepts considered throughout this study. Sustainability deals with the utilization of renewable and replaceable sugar-based twelve most promising building blocks included in the report prepared by U.S. Department of Energy and green engineering concept is related with the incorporation of environmental performance criteria to chemical process design. Process performance criteria at the conceptual design stage are selected as persistence, bioaccumulation and aquatic toxicity, economical potential of the processes, atom &amp / mass efficiency of the processes and the relationship between Gibbs free energy of reaction values and economical potential. It is observed that bioaccumulation potentials of both the raw materials and products are low. Petrochemical raw materials are more persistent in air than the bio-based ones. The aquatic toxicity of bio-based raw materials is low / whereas some of the petrochemicals are moderately toxic and allyl alcohol and acrylonitrile among the petrochemicals are classified as highly toxic. Bio -based routes are not economically feasible with 2002 market prices. Atom and mass efficiencies of petrochemical reactions for a group of chemicals are higher than bio-based ones due to mostly addition or substitution reactions. Among high number of products, 1,3 propanediol production from glycerol with two microorganisms is analyzed at preliminary design stage. Process performance criteria are selected as material and energy consumption, cooling water requirement, CO, CO2, SO2 and NOX emissions to the atmosphere per unit of 1,3 propanediol production. Klebsiella pneumoniae process requires less cooling water, but it is less energy efficient and causes higher emissions.

The aim of this Master Thesis was to calculate and visualize performance indicators for the secondary treatment step in municipal wastewater treatment plants. Performance indicators are a valuable tool to communicate process conditions and energy efficiency to both management teams and operators of the plant. Performance indicators should be as few as possible, clearly defined, easily measurable, verifiable and easy to understand. Performance indicators have been calculated based on data from existing wastewater treatment plants and qualified estimates when insufficient data was available. These performance indicators were then evaluated and narrowed down to a few key indicators, related to process performance and energy usage. Performance indicators for the secondary treatment step were calculated for four municipal wastewater treatment plants operating three different process configurations of the activated-sludge technology; Sternö wastewater treatment plant (Sweden) using a conventional activated-sludge technology, Ronneby wastewater treatment plant (Sweden) using a ring-shaped activated-sludge technology called oxidation ditch, Headingley wastewater treatment plant (Canada) and Kimmswick wastewater treatment plant (USA), both of which use sequencing batch reactor (SBR) activated-sludge technology. Literature reviews, interviews and process data formed the basis of the Master Thesis. The secondary treatment was studied in all the wastewater treatment plants. Performance indicators were calculated, to the extent it was possible, for this step in the treatment process. The results showed that all the wastewater treatments plants, studied in this master thesis, were well below regulatory requirements of effluent concentrations of organic matter and nutrients. This gap between legislated requirements and performance provides an opportunity for improving energy efficiency and maintaining discharge requirements. The removal of organic matter was consistently high at all wastewater treatment plants studied but the removal of nitrogen was slightly lower during the colder months. The results further showed that the discharge of nitrogen from wastewater treatment plants is the largest stress on the recipient. Data regarding the energy usage was almost nonexistent and energy for aeration was therefore calculated when possible since it is aeration that accounts for the largest fraction of energy usage in a wastewater treatment plant. Sternö wastewater-treatment plant proved to be more energy efficient than Rustorp wastewater treatment plant.

There have been significant advances in the information systems (IS) literature about the business value that can be realized through information technology (IT) investments and the mechanisms through which IT creates different facets of business value. We identify three important gaps in understanding the literature on IT business value. First, it is unclear how risk arising from deficiencies in a firm’s information environment, along with internal and external contextual factors, affects a firm’s IT implementation choices. Second, it is unclear how IT resources in a focal domain need to be combined with knowledge resources in the same domain and IT resources in other domains to develop process capabilities and create process-level benefits. Third, it is unclear what risks IT-enabled process innovations create for different process stakeholders and what controls can be applied to mitigate these risks. My dissertation addresses the above three gaps in three essays. The first essay examines the influence of a firm’s information risk on its prioritization of accounting enterprise systems (AES) relative to complementary enterprise systems and the moderation of this relationship by the weaknesses of internal controls and environmental uncertainty characteristics. The second essay focuses on the impact of AES implementation on a firm’s internal controls process, and the complementary roles of managerial competence and enterprise systems implemented in other domains related to the internal controls process of the firm. The final essay explores the risk factors that can arise for buyers and suppliers due to the use of reverse auctions, and the controls that can be applied to mitigate the key risk factors. In terms of research methods, the first two essays apply econometric analysis to panel datasets constructed from multiple sources and the third essay uses a combination of Delphi studies and semi-structured interviews. Collectively, the essays advance our understanding of (1) the factors underlying a firm’s prioritization of IT investment choices; (2) the mechanisms through which IT resources, in combination with human expertise, create business value; and (3) the risks introduced for different stakeholders by the adoption of IT-enabled process innovations and the controls that can be used to effectively mitigate them.
