Statistical Reliability Of Wind Power Scenarios And Stochastic Unit Commitment Cost, Didem Sari, Sarah M. Ryan Nov 2018

Statistical Reliability Of Wind Power Scenarios And Stochastic Unit Commitment Cost, Didem Sari, Sarah M. Ryan

Industrial and Manufacturing Systems Engineering Publications

Probabilistic wind power scenarios constitute a crucial input for stochastic day-ahead unit commitment in power systems with deep penetration of wind generation. To minimize the cost of implemented solutions, the scenario time series of wind power amounts available should accurately represent the stochastic process for available wind power as it is estimated on the day ahead. The high computational demands of stochastic programming motivate a search for ways to evaluate scenarios without extensively simulating the stochastic unit commitment procedure. The statistical reliability of wind power scenario sets can be assessed by approaches extended from ensemble forecast verification. We examine the ...


Evidence Of Problem Exploration In Creative Designs, Jaryn A. Studer, Shanna R. Daly, Seda Mckilligan, Colleen M. Seifert Nov 2018

Evidence Of Problem Exploration In Creative Designs, Jaryn A. Studer, Shanna R. Daly, Seda Mckilligan, Colleen M. Seifert

Industrial Design Publications

Design problems are often presented as structured briefs with detailed constraints and requirements, suggesting a fixed definition. However, past studies have identified the importance of exploring design problems for creative design outcomes. Previous protocol studies of designers has shown that problems can “co-evolve” with the development of solutions during the design process. But to date, little evidence has been provided about howdesigners systematically explore presented problems to create better solutions. In this study, we conducted a qualitative analysis of 252 design problems collected from publically available sources, including award-winning product designs and open-source design competitions. This database offers an independent ...


Conditions Under Which Adjustability Lowers The Cost Of A Robust Linear Program, Ali Haddad-Sisakht, Sarah M. Ryan Oct 2018

Conditions Under Which Adjustability Lowers The Cost Of A Robust Linear Program, Ali Haddad-Sisakht, Sarah M. Ryan

Industrial and Manufacturing Systems Engineering Publications

The adjustable robust counterpart (ARC) of an uncertain linear program extends the robust counterpart (RC) by allowing some decision variables to adjust to the realizations of some uncertain parameters. The ARC may produce a less conservative and costly solution than the RC does but cases are known in which it does not. While the literature documents some examples of cost savings provided by adjustability (particularly affine adjustability), it is not straightforward to determine in advance whether they will materialize. The affine adjustable robust counterpart, while having a tractable structure, still may be much larger than the original problem. We establish ...


Strategies To Redefine The Problem Exploration Space For Design Innovation, Seda Mckilligan, Samantha L. Creeger Sep 2018

Strategies To Redefine The Problem Exploration Space For Design Innovation, Seda Mckilligan, Samantha L. Creeger

Industrial Design Conference Presentations, Posters and Proceedings

Designers are used to solving problems that are given to them, leading them to focus on creating feasible solutions rather than exploring novel perspectives on the presented problems. Creative innovations in problem understanding may lead directly to more innovation solutions. Although problem exploration has been identified as a key process in design thinking, how designers restructure and reframe the problem is not fully examined. The present work aimed to understand how designers intentionally explore variants of problems on the way to solutions. Through an empirical study industrial design students, we documented a high degree of variation in the problem perspectives ...

Industrial and Manufacturing Systems Engineering Conference Proceedings and Posters

The WEAR Scale was used to collect data on the social acceptability of three wearable devices from 1,387 participants from the US Midwest and Silicon Valley. The most notable result was that a head-worn “medical device” was rated as more socially acceptable (d=0.78) than the same device described as a “brain fitness tool,” which was the opposite of what was hypothesized. Also, as hypothesized, Silicon Valley participants found the wearables more socially acceptable than Midwestern U.S. participants. The Scale and these results enable industry to better predict the human factors affecting social acceptability of wearables throughout ...

Industrial and Manufacturing Systems Engineering Conference Proceedings and Posters

The Reading the Mind in the Eyes (RME) test was originally developed to help distinguish between persons with and without autism (Baron-Cohen et al., 2001). Recently the RME test has been shown to relate to a collective intelligence, defined as the ability of a group to perform a wide variety of tasks (Woolley et al., 2010). While these previous results may suggest that the RME measures a pre-determined ability it is an open question of whether RME test scores can be improved by strategically training participants to recognize the mental states of individuals from their faces. Preliminary work was done ...

Traffic Incident Managers (TIMs) coordinate first responders and help resolve traffic-related incidents. Currently, some use over fifteen different software applications with unique functionalities across three monitors to manage incidents, leading to redundant data entry, unnecessary task switching, and delayed responses. 40 hours of TIMs’ screens were recorded during their normal work hours at the Iowa Department of Transportation (DoT). The resulting task analysis from these videos greatly influenced the design of a simplified, web-based, user interface (UI) prototype. The new UI offers a 42.9% reduction in the steps required to manage an incident by combining the functionality of the ...
