Investigation Cost Deviation of Highway Project

Statistical analysis of deviation of actual cost from estimated cost using actual project data

This paper analyzes cause and effect of the deviation of actual cost (measured by personmonth) from estimated cost for software development project. Although the obtained results themselves may not be new from the academic point of view, they may give a nice motivation for developers to join process improvement activities in the software company and thus become a driving force for promoting pro...

Models for Highway Cost Allocation

Highway improvement project selection by the joint consideration of cost-benefit and risk criteria

Since highway improvement project selection requires screening thousands of road segments with respect to crashes for further analysis and final project selection, we provide a two-step project selection methodology and describe an application case to demonstrate its advantages. In the first step of the proposed methodology, we will use odds against observing a given crash count, injury count, ...

Basic Theory of Highway Project Evaluation

The criterion for making good investments is to select projects for which the net benefits are positive, i.e., incremental benefits exceed incremental costs. The major analytic steps are: define alternatives, evaluate impacts, and select the project with highest net benefits. If pricing is determined independently of marginal cost, however, pricing is exogenous and the investment evaluation is ...

Effects of Project Uncertainties on Nonlinear Time-Cost Tradeoff Profile

This study presents the effects of project uncertainties on nonlinear time-cost tradeoff (TCT) profile of real life engineering projects by the fusion of fuzzy logic and artificial neural network (ANN) models with hybrid meta-heuristic (HMH) technique, abridged as Fuzzy-ANN-HMH. Nonlinear time-cost relationship of project activities is dealt with ANN models. ANN models are then integrated with ...
