Aerospace composite manufacturing cost models as geometric programs
… fraught with billions of dollars of production cost overruns. This research develops a novel approach to manufacturing cost modeling during the conceptual design phase using Geometric Programming (GP). A new formulation of a closed queuing network as a GP is presented to capture the crucial cost …

Irrigation cost models to assess the feasibility and potential expansion of large-scale riparian irrigation in Virginia
… were built using the BASIC language. The design models used agronomic, meteorological, economic, and environmental variables to design an irrigation system. Next, the design models computed the variable and fixed cost associated with a portable pipe, fixed big gun, traveling gun, and center pivot …

ProgGen: Automatic Dataset Generation for the Halide Domain Specific Language
Compilers use cost models to choose between different optimization opportunities, and increasingly these cost models are developed using data-driven techniques. Compilers for general-purpose languages rely on large real-world program datasets to train their cost models. However, cost models for …

A robust Shewhart control chart adjustment strategy
… between the control limits is reduced. Three cost models are developed to describe the total cost per unit time of monitoring the mean of a process using both the standard and the generalized Shewhart control chart. The cost models are developed under the assumption that the quality …

The Impact of Reliability in Conceptual Design - An Integrated Trade-off Analysis
… presented in this paper focuses on developing models to estimate the systemreliability of Unmanned Ground Vehicles using knowledge and data from similar systems. Traditional reliability approaches often require detailed knowledge of a system and are used in later design stages as well as …

Software development cost estimating models: an application of the hedonic pricing approach
Software development cost estimating models were analyzed using an application of the hedonic pricing approach. Several recently proposed software cost estimating tools were surveyed for the purpose of revealing their roots in the hedonic pricing approach. The analysis includes discussion of the …

Joint Hedonic Travel Cost Method: Combining Revealed and Stated Preference Data to Estimate Demand for Attribute Quality of Sport Fishing in Illinois
… evaluates the performance of the hedonic travel cost method by applying recent methodological advances in recreation valuation: conjoint analysis and combined revealed and stated preference data. The combination of these techniques creates a joint hedonic travel cost method that consists of using …

Neural network-based cost estimating
This thesis presents a neural network-based cost estimating method, developed for the generation of conceptual cost estimates for low-rise prefabricated structural steel buildings. Detailed cost estimating is current practice for this type of buildings, since cost estimators are often challenged by …

Decarbonizing the Global Shipping Industry: Evaluating Pathways for Alternative Fuels
… and feedstock. Each pathway is assessed based on cost and multi-attribute utility using system-level metrics relevant to shipping. For alternative fuels, fuel cost models have been developed to estimate the levelized cost of production based on varying electricity prices, natural gas prices, and …
