Sensitivity analysis of the Catchment Modeling Framework (CMF) and use in evaluating two agricultural management scenarios

Creator:: Metta, John W. P.
Abstract:: Abstract Watershed-scale fate/transport modeling of contaminants is a tool that scientists and land managers can use to assess pesticide contamination to stream systems. The Catchment Modeling Framework (CMF) is a catchment-scale fate/transport modeling tool. It was developed to help scientists and land managers assess the effects of possible land-use decisions...

A mathematical modeling framework for scheduling and managing multiple concurrent tasks

Creator:: Shakeri, Shakib
Abstract:: Occurrence of human error in highly complex systems, such as a cockpit, can be disastrous and/or overwhelmingly costly. Mismanagement of multiple concurrent tasks has been observed by researchers to be a type of repetitive human error in previous studies of accidents and incidents. This error may occur in the form...

Three studies on the role of uncertainty in the valuation and management of renewable natural resources

Creator:: Burnes, Ellen Irene
Abstract:: These three papers address uncertainty in the management and valuation of renewable natural resources. The first paper develops a model to integrate both stock and price uncertainty to obtain optimal resource levels. The model is an extension of Reed (1974) and shows by proof and by example that when prices...

Optimizing the primary forest products supply chain : a multi-objective heuristic approach

Creator:: Hamann, Jeff D.
Abstract:: This thesis is a collection of four submitted manuscripts that present methods to assist forest ecosystem service managers wanting to develop operational sampling, monitoring, and production plans for a set of specific quantifiable ecosystem services, which are formulated as a series of general multi-objective optimization problems. The problems are solved...

Optimization, conservation and valuation of contingent claims in economic resource management under uncertainty

Creator:: Jia, Siwei
Abstract:: This dissertation consists of three papers studying optimization, conservation and valuation of contingent claims in economic resource nianagement under uncertainty. In the first paper the Markovian optinial policies are studied for resource management in a finite time horizon. Under sonic conditions, in particular, when the prices are stochastic and there...

Spatially explicit inter-temporal forest management decision under the risk of fire

Creator:: Konoshima, Masashi
Abstract:: This paper presents a framework for analyzing efficient spatial allocation of forest management efforts - fuel treatment and harvest - under the risk of fire. The framework integrates a fire behavior model and a spatially-explicit stochastic dynamic optimization model. I investigate the effects of spatial interaction across plots during forest...

Essays on natural endowments, conservation policy, and community characteristics

Creator:: Lin, Haixia
Abstract:: To protect and restore environmental quality, efficient and effective conservation policies are needed. Designing policies require a sound understanding of the contributions of natural endowments to economic vitality, and the performance and impacts of conservation programs. This dissertation consists of three essays, and addresses several issues relevant to these two...

Efficient heuristics for buffer allocation in closed serial production lines

Creator:: Vergara Arteaga, Hector A.
Abstract:: The optimal allocation of buffers in serial production systems is one of the oldest and most researched problems in Industrial Engineering. In general, there are three main approaches to the buffer allocation problem when the objective is to maximize throughput. The first is basically a systematic trial and error procedure...

Evaluation of models for estimating surface irrigation infiltration parameters : Data protocols and algorithm performance

Creator:: Isbell, Sarah A.
Abstract:: Often furrow irrigation application efficiencies are low compared to sprinkler systems. The primary goal of furrow irrigation is to infiltrate a relatively uniform target depth of water necessary for the crop, while minimizing the amount of runoff. The concept is difficult because water can infiltrate differently at all locations in...

Equipment replacement prioritization measures : simulation and testing for a vehicle fleet

Creator:: Kriett, Phillip Oliver
Abstract:: Oregon Department of Transportation (ODOT) Fleet Services manages a fleet that in 2008 included approximately 5,000 pieces of active equipment worth $340–$390 million. Every biennium, a fixed budget is available to replace a certain amount of this equipment. This research evaluated various measures for establishing equipment replacement priorities. A model...
