Concurrent cost estimating
A methodology for concurrent cost estimating is proposed, developed, and demonstrated. The approach is novel in that the traditional means of process planning is exploited without being time-consuming and iterative, as is typical. Design abstractions are used to characterize the component …

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 …

ACCURACY IN DESIGN STAGE COST ESTIMATING
Design stage cost estimating or prediction of the successful tender bid is recognised as one of the important functions of the quantity surveying profession. Despite this recognised importance, many practicing quantity surveyors are unaware of their own performance as regards to the level of …

Improving the parametric method of cost estimating relationships of naval ships
… focus on determining methods to reduce the cost of Navy ships. A RAND National Defense Research Institute study showed many sources of cost escalation for Navy ships. Among them included characteristic complexity of modem Naval ships, which contributed to half of customer driven factors. …

An Exploration of parametric software cost estimating models for Jackson Systems Development
Most parametric software cost estimation models used today evolved in the late 70's and early 80's. At that time, the dominant software development techniques being used were the early 'structured methods'. Since then, several new systems development paradigms and methods have emerged, one being …

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 …

An object-oriented design intent externalization and representation model for cost estimating applications
… to as "design intent," which is of essence to cost estimating. Design intent can improve various facets of cost estimating. This research discusses the potential use of design intent knowledge in material selection and substitution, shop drawing preparation and value engineering. The first …

An Alternative Method for Determining Adjusted Function Points as the Basis for Software Cost Estimating
<p>As software costs become an increasingly higher percentage of total computer system costs, it becomes increasingly more important for software development managers to have the ability to predict development costs with reasonable accuracy early in the software development cycle. Software …

The design, development, and evaluation of a prototype training course life cycle cost estimating tool
A prototype cost estimating tool was built using an iterative design approach to help training managers assess the impact of changes in the training environment on course life cycle costs. In the first of two evaluations, training managers evaluated the prototype tools during a demonstration for …

Cost Modeling Based on Support Vector Regression for Complex Products During the Early Design Phases
The purpose of a cost model is to provide designers and decision-makers with accurate cost information to assess and compare multiple alternatives for obtaining the optimal solution and controlling cost. The cost models developed in the design phases are the most important and the most difficult to …
