Architecture Value Mapping: Using Fuzzy Cognitive Maps As A Reasoning Mechanism For Multi-Criteria Conceptual Design Evaluation, Atmika Singh
Doctoral Dissertations
"The conceptual design phase is the most critical phase in the systems engineering life cycle. The design concept chosen during this phase determines the structure and behavior of the system, and consequently, its ability to fulfill its intended function. A good conceptual design is the first step in the development of a successful artifact. However, decision-making during conceptual design is inherently challenging and often unreliable. The conceptual design phase is marked by an ambiguous and imprecise set of requirements, and ill-defined system boundaries. A lack of usable data for design evaluation makes the problem worse. In order to assess a …
Integration Of Model-Based Systems Engineering And Virtual Engineering Tools For Detailed Design, 2011 Missouri University of Science and Technology
Integration Of Model-Based Systems Engineering And Virtual Engineering Tools For Detailed Design, Akshay Kande
Masters Theses
"Design and development of a system can be viewed as a process of transferring and transforming data using a set of tools that form the system's development environment. Conversion of the systems engineering data into useful information is one of the prime objectives of the tools used in the process. With complex systems, the objective is further augmented with a need to represent the information in an accessible and comprehensible manner. The importance of representation is easily understood in light of the fact that the stakeholder's ability to make prompt and appropriate decisions is directly related to his understanding of …
The Effects Of Anti-Price Gouging Legislation On Supply Chain Dynamics, 2011 California Polytechnic State University, San Luis Obispo
The Effects Of Anti-Price Gouging Legislation On Supply Chain Dynamics, Jason Edward Maynard
Master's Theses
The purpose of this thesis is to model the effects of anti-price gouging (APG) legislation on the costs to businesses during the recovery period of a disaster. A system dynamics model of a business’s replenishment procedures is used to simulate the effects of APG legislation on business performance. Economists have published expansive research on the effects of price ceilings on supply and demand, but there is little research evidence on the operational consequences of price ceiling legislation on business costs. APG legislation increases consumer’s forward buying and shortage gaming after a disaster by removing price incentives to be frugal. Forward …
Assessing System Architectures: The Canonical Decomposition Fuzzy Comparative Methodology, 2011 Missouri University of Science and Technology
Assessing System Architectures: The Canonical Decomposition Fuzzy Comparative Methodology, Jason Paul Dauby
Doctoral Dissertations
"The impacts of decisions made during the selection of the system architecture propagate throughout the entire system lifecycle. The challenge for system architects is to perform a realistic assessment of an inherently ambiguous system concept. Subject matter expert interpretations, intuition, and heuristics are performed quickly and guide system development in the right overall direction, but these methods are subjective and unrepeatable. Traditional analytical assessments dismiss complexity in a system by assuming severability between system components and are intolerant of ambiguity. To be defensible, a suitable methodology must be repeatable, analytically rigorous, and yet tolerant of ambiguity. The hypothesis for this …
Evaluating The Impact Of Patient Arrival Patterns In The Performance Of Appointment Scheduling Rules, 2010 University of South Florida
Evaluating The Impact Of Patient Arrival Patterns In The Performance Of Appointment Scheduling Rules, Alcides Santander-Mercado, Jose Zayas-Castro, Laila Cure, Ali Yalcin
Laila Cure
This paper evaluates the ability of commonly used Appointment Scheduling Rules (ASRs) in smoothing the effect of environmental factors in the performance of an outpatient scheduling system. ASRs have been widely implemented in outpatient clinics to improve performance measures such as staff idle time, patient waiting time, and facility congestion. However, the successful implementation of an ASR depends on its ability in dealing with the environmental factors affecting the system. Factors such as no-shows, variability of consultation times, patient unpunctuality, walk-in patient arrivals and the number of admitted patients per session affect the performance of the clinics in terms of …

An Improved Ant Colony System For A Real Time Routing Strategy, 2010 Mazandaran University of Science and Technology, Department of Industrial Engineering
An Improved Ant Colony System For A Real Time Routing Strategy, Hannaneh Rashidi-Bajgan, Taravatsadat Nehzati, Napsiah Ismail
Hannaneh Rashidi-Bajgan
There is a large number of literatures about routing and dispatching plans for automated guided vehicle system (AGVS), however a small fraction of these works dealt with dynamic characteristic of this kind of scheduling problems. Current paper surveys a real time strategy to responding requests for supposed material handling system in the plant. We arranged this designing on a preplanned system where all data are known before the constructing routes. An improved ant colony optimization (ACO) is applied in order to find the shortest route path as new solicitations happened. We explore ACO initially for static version of the problem, …
Multi-Modular Integral Pressurized Water Reactor Control And Operational Reconfiguration For A Flow Control Loop, 2010 University of Tennessee - Knoxville
Multi-Modular Integral Pressurized Water Reactor Control And Operational Reconfiguration For A Flow Control Loop, Sergio Ricardo Pereira Perillo
Doctoral Dissertations
This dissertation focused on the IRIS design since this will likely be one of the designs of choice for future deployment in the U.S and developing countries. With a net 335 MWe output IRIS novel design falls in the “medium” size category and it is a potential candidate for the so called modular reactors, which may be appropriate for base load electricity generation, especially in regions with smaller electricity grids, but especially well suited for more specialized non-electrical energy applications such as district heating and process steam for desalination. The first objective of this dissertation is to evaluate and quantify …
Closing The Gap Between The Industry And Higher Education Institutions- Case Examples From East African Region, 2010 The University of the South Pacific
Closing The Gap Between The Industry And Higher Education Institutions- Case Examples From East African Region, Deogratias Harorimana Mr
Dr Deogratias Harorimana
Much complained about is the quality of graduates Universities put on the labour market. Less talked about however is why knowledge institutions seems to be bad knowledge managers. In this presentation I argue that DIRECT collaborative relationship between Industry,Governments and Higher Education Institutions is a per-requisite.Good relationship is key to building such a successful knowledge transfer strategies between Industries and Educational and Research Institutions. This paper explores what makes a good Knowledge Transfer Partnership Strategy and highlights some key lessons for businesses, Universities and Government bodies. This paper was a Key note presentation to the Annual International Conference on Building …

Stability Of Traffic Flow Behavior With Distributed Delays Modeling The Memory Effects Of The Drivers, Rifat Sipahi, Fatihcan M. Atay, Silviu-Julian Niculescu
Rifat Sipahi
Stability analysis of a single-lane microscopic car-following model is studied analytically from the perspective of delayed reactions of human drivers. In the literature, the delayed reactions of the drivers are modeled with discrete delays, which assume that drivers make their control decisions based on the stimuli they receive from a point of time in the history. We improve this model by introducing a distribution of delays, which assumes that the control actions are based on information distributed over an interval of time in history. Such an assumption is more realistic, as it takes into consideration the memory capabilities of the …
