Automatically Generating Scenarios From A Text Corpus: A Case Study On Electric Vehicles, Christopher W.H. Davis, Antoine J. Jetter, Philippe J. Giabbanelli
Automatically Generating Scenarios From A Text Corpus: A Case Study On Electric Vehicles, Christopher W.H. Davis, Antoine J. Jetter, Philippe J. Giabbanelli
Engineering and Technology Management Faculty Publications and Presentations
Creating ‘what-if’ scenarios to estimate possible futures is a key component of decision-making processes. However, this activity is labor intensive as it is primarily done manually by subject-matter experts who start by identifying relevant themes and their interconnections to build models, and then craft diverse and meaningful stories as scenarios to run on these models. Previous works have shown that text mining could automate the model-building aspect, for example, by using topic modeling to extract themes from a large corpus and employing variations of association rule mining to connect them in quantitative ways. In this paper, we propose to further …
An Assessment Of The Decision-Making Units' Efficiency In Service Systems, Maoloud Yakhlif Dabab
An Assessment Of The Decision-Making Units' Efficiency In Service Systems, Maoloud Yakhlif Dabab
Dissertations and Theses
Most tools and models of performance and quality of service management are generic and do not solve complex technical systems. The critical components of the system need such tools to assess their efficiency to make a better decision about them. One of the primary objectives in the service systems is to improve the ability of efficiency, effectiveness, and sustainability of critical assets. One of the challenges with improving critical assets is the amount of major capital spending needed to upgrade a technology infrastructure with a high obsolescence rate. This along with usage and reliability issues, makes evaluating mobile cells to …

In the event that a transmission planning process to examine the potential need to assess and build transmission facilities to connect these wind resource areas is launched at a future date, the results of this study will assist planners by obtaining initial stakeholder views on the breadth of choices that should be considered, and more importantly, provide key insights on …
Toward Understanding Pu And Peou Of Technology Acceptance Model, Nayem Rahman
Toward Understanding Pu And Peou Of Technology Acceptance Model, Nayem Rahman
Student Research Symposium
Technology Acceptance Model (TAM) is considered one of the most popular models used in Information System (IS) research. Fred Davis developed this model as part of his doctoral research at MIT in 1986. Since then this model has been widely used in IS research and other disciplines. Two main components of TAM are Perceived Usefulness (PU) and Perceived Ease of Use (PEOU). This model allowed researchers to plug-in external factors to these two components. Researchers have used a variety of external factors to draw relationships between these two internal factors of TAM model. However, most of the research used these …
Using Fuzzy Cognitive Maps To Model Policy Issues In The Face Of Uncertainty And Limited Data, Brian Gregor
Using Fuzzy Cognitive Maps To Model Policy Issues In The Face Of Uncertainty And Limited Data, Brian Gregor
PSU Transportation Seminars
Planners and policymakers are often faced with the need to make decisions about issues for which there is uncertainty and limited data. For example, transportation planners are now faced with the prospect that new transportation technologies such as autonomous vehicles could greatly alter future transportation system needs. Decisions about these types of issues are difficult to reason about and consequently are likely to be ignored or made on the basis of simplistic logic. Although modeling could be helpful, especially for issues involving complex systems, it is rarely used because models usually require large amounts of data and and handle uncertainty …
Understanding Risk Perception Using Fuzzy Cognitive Maps, Pei Zhang, Antoine J. Jetter
Understanding Risk Perception Using Fuzzy Cognitive Maps, Pei Zhang, Antoine J. Jetter
Engineering and Technology Management Faculty Publications and Presentations
When making decision that can have far-researching effects, such as governmental policies or decisions on new technologies, decision-makers use their understanding of the risks that are associated with their choices to guide their decisions. Measuring how people perceive risks can be helpful for understanding and possibly improving the decision-making process. Building on a review of existing methods for investigating risk perceptions, this paper suggests Fuzzy Cognitive Maps (FCM) as a method for investigating differences in risk perception among stakeholders and stakeholder groups. The approach is illustrated with an example of wildfire risk perceptions. Results suggest that FCM can contribute to …

On Valuing Biopharmaceutical Product Pipelines: An Effectuation Model And Evidence, Mark J. Ahn, Anne S. York, Wei Wu, Yulianto Suharto, Tugrul Unsal Daim
Engineering and Technology Management Faculty Publications and Presentations
New creative approaches are needed to manage emerging biotechnology innovations, regulations, and payor environments to enhance product pipeline productivity, valuation, and risk management. Biopharmaceutical firms must make dynamic resource allocation decisions on their relative levels of internal R&D and external strategic alliances in furthering their pipelines. As the predominant method of using discounted cash flow (DCF) methodologies may lead to chronic underinvestment and performance, we evaluated the integration of traditional DCF with an effectuation model of analysis. Unlike traditional financial models that begin with the end goal of assumed known cash flows and recursively solve for portfolio optimization, the effectuation …

To do that, the most popular [1][2] social cognitive theories conceived over the past four decades are reviewed analytically from …
Project Management In Product Development: Toward A Framework For Targeted Flexibility, Antonie J. Jetter, Fatima Albar
Project Management In Product Development: Toward A Framework For Targeted Flexibility, Antonie J. Jetter, Fatima Albar
Engineering and Technology Management Faculty Publications and Presentations
As a discipline, project management has been accused of having lost its relevance for innovative initiatives because it emphasizes planning and control over the flexibility and learning-based strategies that are needed to succeed under uncertainty. Several authors therefore recommend adaptive project management practices - sometimes named “targeted flexibility” - that respond to project characteristics commonly found in innovation, namely novelty, complexity, speed and - as a result - uncertainty. This paper investigates how this proposed adaptation of project management occurs in a context with high levels of novelty that organizes work in projects and needs to accommodate projects of different …
Connecting Customers With Engineers For The Successful Fuzzy Front End: Requirements Of Tools, Byung Sung Yoon, Antonie J. Jetter
Connecting Customers With Engineers For The Successful Fuzzy Front End: Requirements Of Tools, Byung Sung Yoon, Antonie J. Jetter
Engineering and Technology Management Faculty Publications and Presentations
In technology-driven enterprises, marketing typically acts as a “go-between” that captures customer needs and experiences and aggregates and interprets them for engineering. Knowledge exchange thus occurs through an indirect path. However, as a result of rapidly changing and unpredictable environments and complex products with tacit requirements, companies increasingly emphasize the need for engineering to be more strongly engaged with customers'. Accordingly, an increasing number of methods for customer research in early stages on new product development, the so-called fuzzy front end (FFE), emphasize direct knowledge exchange and collaboration between engineering and customers. Based on a review of the literature, this …
Project Ranking Using Partial Ranks, Jiali Ju, Pei Zhang, Tim R. Anderson
Project Ranking Using Partial Ranks, Jiali Ju, Pei Zhang, Tim R. Anderson
Engineering and Technology Management Faculty Publications and Presentations
A competition was recently held for new elder care technologies and a method was needed for selecting an audience favorite project. Since each of the eight projects received a half hour presentation time slot spread out over a full day, attendance varied significantly with morning projects having a much lower attendance. An algorithm was desired that was robust with respect to varying evaluator. A new algorithm for aggregating ranks from a large number of incomplete judgment was developed and applied to the projects to select a winner. This paper presents the new algorithm, tests the new approach against others in …
Managing The Economic Constraints Of Foundries And Fabless Enterprises, Charles M. Weber, Jiting Yang
Managing The Economic Constraints Of Foundries And Fabless Enterprises, Charles M. Weber, Jiting Yang
Engineering and Technology Management Faculty Publications and Presentations
This paper presents an empirically grounded model, which links organizational learning to pattern-specific fixed costs. The approach described in this paper helps fab managers make fundamental strategic decisions concerning product design and product mix by engaging in scenario planning. Four critical aspects of managing pattern-specific fixed cost are analyzed in detail – sensitivity to time, design cost and production volume; platform designs; process postponement solutions; and design penalties. The model suggests that fabless enterprises and foundries must collaborate extensively on the design and realizations of product platforms for state-of-the-art integrated circuit products to remain economically viable.

These roadmaps are an important element in the Bonneville Power Administration's strategic approach …
Fast And Frugal Heuristics For New Product Screening - Is Managerial Judgment "Good Enough?", Antonie J. Jetter, Fatima M. Albar
Fast And Frugal Heuristics For New Product Screening - Is Managerial Judgment "Good Enough?", Antonie J. Jetter, Fatima M. Albar
Engineering and Technology Management Faculty Publications and Presentations
Project screening in the fuzzy front-end of product development is dominantly based on managerial judgment, yet little is known about the quality of heuristic screening decisions. This research models three commonly discussed fast and frugal (F&F)heuristics for project screening (take-the-best, tallying and elimination-by-aspect) and explores their performance. An illustrative dataset of 52 new product development projects is used to compare the performance of F&F heuristics against that of regression models, which reflect compensatory judgment behaviour. The findings uncover a 'less is more' effect that justifies the use of simple heuristics in early stage product screening; two out of the three …

An Investigation On Fast And Frugal Model For New Project Screening, Antonie J. Jetter, Fatima M. Albar
Engineering and Technology Management Faculty Publications and Presentations
Research in psychology is increasingly interested in decision-makers' use of heuristics or rules of thumb because they have accuracies close to more complex decision rules and seem particularly useful in difficult decision-making contexts when uncertainty is high and speed is of the essence. One particularly difficult decision setting is the fuzzy front-end of new product development because a large number of product ideas need to be screened to identify the few that should be developed further. This process is currently poorly supported through decision tools and mainly occurs on the basis of managerial “gut-feel”. This study explores managerial “gut-feel” by …
Heuristics In Decision Making, Fatima M. Albar, Antonie J. Jetter
Heuristics In Decision Making, Fatima M. Albar, Antonie J. Jetter
Engineering and Technology Management Faculty Publications and Presentations
Heuristics are simple rules of thumbs for problem solving that follow a logic that is quite different from consequential logic. They have long been regarded, as an inferior technique for decision making that is the source of irrational decision behavior. Recently, decision making researchers have demonstrated that some heuristics are highly efficient and can compete with complex decision models in some application domains. This paper explores the different streams of research, summarizes the state of the art decision making model, and discusses its implications for complex decisions in engineering and technology management.
Theoretical Framework For Managing The Front End Of Innovation Under Uncertainty, Antonie J. Jetter, Richard Sperry
Theoretical Framework For Managing The Front End Of Innovation Under Uncertainty, Antonie J. Jetter, Richard Sperry
Engineering and Technology Management Faculty Publications and Presentations
A growing body of research suggests that the fuzzy front-end of product development should not be managed with a one-size-fits-all standard process. Instead, projects with different market and technical uncertainties should be managed with one of five different processes (linear, recursive, evolving, selectionism, trial-and-error). Based on a review of the literature, the paper develops a theoretical framework for front-end management which provides the foundation for ongoing empirical research.
Fuzzy Cognitive Maps For Engineering And Technology Management: What Works In Practice?, Antonie J. Jetter
Fuzzy Cognitive Maps For Engineering And Technology Management: What Works In Practice?, Antonie J. Jetter
Engineering and Technology Management Faculty Publications and Presentations
Due to a lack of available data, many early planning decisions in engineering and technology management have to be based on experts' opinions and their qualitative statements about evolving technologies, markets and general business environments. Several authors have suggested the use of fuzzy cognitive maps (FCMs) to analytically support these decisions with simulation models that can cope with qualitative information. However, only little practice experience is documented. Based on multiple case studies and an extensive literature review, the paper reviews the state-of-the-art of FCM-practice and introduces a six-step guideline for practitioners and researchers who wish to apply FCMs to real-world …
Do Maps Guide The Way To Npd Success? Theoretical And Practical Aspects Of Knowledge Mapping In Product Development, Antonie J, Jetter
Do Maps Guide The Way To Npd Success? Theoretical And Practical Aspects Of Knowledge Mapping In Product Development, Antonie J, Jetter
Engineering and Technology Management Faculty Publications and Presentations
New product development success largely depends on the ability to combine newly acquired information on customer demands and technological options with knowledge that exists within the company. Project organization and high employee turnover, however, make it difficult to be informed about what knowledge is available within the company and to access it successfully. Knowledge maps, a popular concept in present knowledge management, offer a possible solution by ?guiding the way to knowledge?. Their purpose, structure and content varies greatly, as does their ability to capture different aspects of knowledge. This paper investigates the theoretical basis of different types of knowledge …
Educating The Guess: Strategies, Concepts And Tools For The Fuzzy Front End Of Product Development, Antonie J. Jetter
Educating The Guess: Strategies, Concepts And Tools For The Fuzzy Front End Of Product Development, Antonie J. Jetter
Engineering and Technology Management Faculty Publications and Presentations
Many companies lack efficient management of the early phases of new product development (NPD) - the socalled fuzzy front end (FFE). Rather than on structured methods, decision makers rely on ?gut ?feel? or ?guessing?. In an attempt to ?educate the guess? this paper discusses the activities and challenges of the FFE, as well as strategies to manage them successfully. It then briefly presents traditional and recent approaches to front-end management support. Based on the identified strengths and weaknesses of existing front-end solutions, the framework of a new management support system for the FFE is presented. Conceptually, the system is based …
The Fixed Weighting Nature Of A Cross-Evaluation Model, Timothy R. Anderson, Keith Hollingsworth, Lane Inman
The Fixed Weighting Nature Of A Cross-Evaluation Model, Timothy R. Anderson, Keith Hollingsworth, Lane Inman
Engineering and Technology Management Faculty Publications and Presentations
Cross-evaluation has been touted as a powerful extension of Data Envelopment Analysis that provides, not only a unique ordering among the Decision Making Units (DMUs), but also eliminates unrealistic weighting schemes without requiring the elicitation of weight restrictions from application area experts. The goal of this paper is to prove, in the single-input, multiple-output case, cross-evaluation implicitly uses a single fixed set of weights. We demonstrate how this unseen fixed set of weights may still be unrealistic.
Bayesian Inquiry: An Approach To The Use Of Experts, King G. Yee
Bayesian Inquiry: An Approach To The Use Of Experts, King G. Yee
Dissertations and Theses
Subjective information is a valuable resource; however, decisionmakers often ignore it because of difficulties in eliciting it from assessors. This thesis is on Bayesian inquiry and it presents an approach to eliciting subjective information from assessors. Based on the concepts of cascaded inference and Bayesian statistics, the approach is designed to reveal to the decision-maker the way in which the assessor considers his options and the reasons he has for selecting particular alternatives. Unlike previous works on cascaded inferences, the approach here focuses on incoherency. Specifically, it employs the use of additional information to revise and check the estimates. The …
