Effects Of Data Resolution And Human Behavior On Large Scale Evacuation Simulations, Wei Lu
Effects Of Data Resolution And Human Behavior On Large Scale Evacuation Simulations, Wei Lu
Doctoral Dissertations
Traffic Analysis Zones (TAZ) based macroscopic simulation studies are mostly applied in evacuation planning and operation areas. The large size in TAZ and aggregated information of macroscopic simulation underestimate the real evacuation performance. To take advantage of the high resolution demographic data LandScan USA (the zone size is much smaller than TAZ) and agent-based microscopic traffic simulation models, many new problems appeared and novel solutions are needed. A series of studies are conducted using LandScan USA Population Cells (LPC) data for evacuation assignments with different network configurations, travel demand models, and travelers’ compliance behavior.
First, a new Multiple-Source-Nearest-Destination Shortest Path …
A Dea Model To Optimize Insurance Payment Plans Based On Pacs, Gagan Rajpal
A Dea Model To Optimize Insurance Payment Plans Based On Pacs, Gagan Rajpal
Doctoral Dissertations
Healthcare industry has evolved dramatically over the time. From being a “cottage industry” to an “organized industry” has brought lot of changes. The changes have been both good and bad. Among the problems that have surfaced in past couple of decades, rising healthcare cost has been one of the most significant. The rising healthcare cost has been documented to be a symptom of several factors. Since the inception of healthcare as an organized industry several payment models for providers and hospitals have been adopted. Current healthcare reforms have proposed new payments models to curb the rising cost and provide consumer …
Modeling And Optimization Of Resource Allocation In Supply Chain Management Problems, Qi Yuan
Modeling And Optimization Of Resource Allocation In Supply Chain Management Problems, Qi Yuan
Doctoral Dissertations
Resource allocation in supply chain management studies how to allocate the limited available resources economically/optimally to satisfy the demands. It is an important research area in operations research. This dissertation focuses on the modeling and optimization of three problems.
The first part of the dissertation investigates an important and unique problem in a supply chain distribution network, namely minimum cost network flow with variable lower bounds (MCNF-VLB). This type of network can be used to optimize the utilization of distribution channels (i.e., resources) in a large supply network, in order to minimize the total cost while satisfying flow conservation, lower …
Moldable Items Packing Optimization, Sima Maleki
Moldable Items Packing Optimization, Sima Maleki
Doctoral Dissertations
This research has led to the development of two mathematical models to optimize the problem of packing a hybrid mix of rigid and moldable items within a three-dimensional volume. These two developed packing models characterize moldable items from two perspectives: (1) when limited discrete configurations represent the moldable items and (2) when all continuous configurations are available to the model. This optimization scheme is a component of a lean effort that attempts to reduce the lead-time associated with the implementation of dynamic product modifications that imply packing changes.
To test the developed models, they are applied to the dynamic packing …
