Application Of Techniques For Map Estimation To Distributed Constraint Optimization Problem, Yoonheui Kim
Application Of Techniques For Map Estimation To Distributed Constraint Optimization Problem, Yoonheui Kim
Doctoral Dissertations
The problem of efficiently finding near-optimal decisions in multi-agent systems has become increasingly important because of the growing number of multi-agent applications with large numbers of agents operating in real-world environments. In these systems, agents are often subject to tight resource constraints and agents have only local views. When agents have non-global constraints, each of which is independent, the problem can be formalized as a distributed constraint optimization problem (DCOP). The DCOP is closely associated with the problem of inference on graphical models. Many approaches from inference literature have been adopted to solve DCOPs. We focus on the Max-Sum algorithm …
Guidelines For Scheduling In Primary Care: An Empirically Driven Mathematical Programming Approach, Hyun Jung Alvarez Oh
Guidelines For Scheduling In Primary Care: An Empirically Driven Mathematical Programming Approach, Hyun Jung Alvarez Oh
Doctoral Dissertations
Primary care practices play a vital role in healthcare delivery since they are the first point of contact for most patients, and provide health prevention, counseling, education, diagnosis and treatment. Practices, however, face a complex appointment scheduling problem because of the variety of patient conditions, the mix of appointment types, the uncertain service times with providers and non-provider staff (nurses/medical assistants), and no-show rates which all compound into a highly variable and unpredictable flow of patients. The end result is an imbalance between provider idle time and patient waiting time. To understand the realities of the scheduling problem we analyze …
Collaborative Models For Supply Networks Coordination And Healthcare Consolidation, Shima Mohebbi
Collaborative Models For Supply Networks Coordination And Healthcare Consolidation, Shima Mohebbi
Doctoral Dissertations
This work discusses the collaboration framework among different members of two complex systems: supply networks and consolidated healthcare systems. Although existing literature advocates the notion of strategic partnership/cooperation in both supply networks and healthcare systems, there is a dearth of studies quantitatively analyzing the scope of cooperation among the members and its benefit on the global performance. Hence, the first part of this dissertation discusses about two-echelon supply networks and studies the coordination of buyers and suppliers for multi-period procurement process. Viewing the issue from the same angel, the second part studies the coordination framework of hospitals for consolidated healthcare …
Developing An Optimal Model For Infant Home Visitation, Isaac Atuahene
Developing An Optimal Model For Infant Home Visitation, Isaac Atuahene
Doctoral Dissertations
The United States, Great Britain, Denmark, Canada and many other countries have accepted home visitation (HV) as a promising strategy for interventions for infants after births and for their mothers. Prior HV studies have focused on theoretical foundations, evaluations of programs, cost/benefit analysis and cost estimation by using hospital/payer/insurance data to prove its effectiveness and high cost. As governments and private organizations continue to fund HVs, it is an opportune time to develop and formulate operations research (OR) models of HV coverage, quality and cost so they might be used in program implementation as done for adult home healthcare (HHC) …
Resource And Supply Allocation And Relief Center Location For Humanitarian Logistics, Guven Ince
Resource And Supply Allocation And Relief Center Location For Humanitarian Logistics, Guven Ince
Doctoral Dissertations
This dissertation examines two salient issues that arise in the strategic planning of disaster management operations for providing relief to populations that are impacted by a disaster, such as an earthquake. The first issue is the alleviation of destitution faced by affected populations in the immediate aftermath of a disaster. The second is the establishment of an infrastructure for provision of relief, for a much longer period of time, until normalcy is restored. Central to the alleviation of destitution is the avoidance of critical shortages in meeting the demand for relief supplies. The literature on pro-active and strategic planning of …
Flexibility And Capacity Allocation Under Uncertain Prescheduled (Non-Urgent) Demand And Same-Day (Urgent) Demand In Primary Care Practices, Xiaoling Gao
Doctoral Dissertations
In this dissertation, we are applying and extending well-established concepts of flexibility in manufacturing and service sectors to a healthcare setting: primary care. In the healthcare scenarios, appointments are booked over time and thus future resource capacity is sequentially being allocated under partial demand information. In manufacturing flexibility is typically presented as a technology choice that requires heavy investment for expensive flexible equipment, or highly cross-trained workers, but can then be used at little or no cost to satisfy demand. In primary care, however, the resources are inherently flexible, as primary care physicians are naturally able to see other panel's …
