Adaptive Sampling Trust-Region Methods For Derivative-Based And Derivative-Free Simulation Optimization Problems, Sara Shashaani
Adaptive Sampling Trust-Region Methods For Derivative-Based And Derivative-Free Simulation Optimization Problems, Sara Shashaani
Open Access Dissertations
We consider unconstrained optimization problems where only “stochastic” estimates of the objective function are observable as replicates from a Monte Carlo simulation oracle. In the first study we assume that the function gradients are directly observable through the Monte Carlo simulation. We propose ASTRO, which is an adaptive sampling based trust-region optimization method where a stochastic local model is constructed, optimized, and updated iteratively. ASTRO is a derivative-based algorithm and provides almost sure convergence to a first-order critical point with good practical performance. In the second study the Monte Carlo simulation is assumed to provide no direct observations of the …

Improvement Of Work Process Performance With Task Assignments And Mental Workload Balancing, Cansu Kandemir
Engineering Management & Systems Engineering Theses & Dissertations
The outcome of a work process depends heavily on which tasks assigned to which employees. However, sometimes-optimized assignments based on employees’ qualifications may result in an uneven and ineffective workload distribution among them. Likewise, an even workload distribution without considering the employee's qualifications may cause unproductive employee-task matching that results in low performance of employees. This trade-off is even more noticeable for work processes during critical time junctions, such as in military command centers and emergency rooms that require being fast and effective without making errors.
This study proposes that optimizing task-employee assignments according to their capabilities while also keeping …

Attending To Scientific Practices Within Undergraduate Research Experiences, Gina Quan, Chandra Turpen, Andrew Elby
Faculty Publications
Ford (2015) argues for viewing “scientific practice” not as a list of particular skills, but rather, more holistically as “sets of regularities of behaviors and social interactions” among scientists. This conceptualization of scientific practices foregrounds how they meaningfully connect to one another and are purposefully employed in order to explain nature. We apply this framework in the context of undergraduate research experiences (UREs) to understand the early forms of student engagement in scientific practices, and how these specific forms of engagement may be consequential for students’ future participation. Using video from interviews with students and research mentors, we argue that …
