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 ...

The online observation of a construction site and processes bears significant advantage to all business sector. BIM is the combination of a 3D model of the project and a project-planning program which improves the project planning model by up to 6D (Adding Time, Cost and Material Information dimensions to the model). RFID technology is an appropriate information synchronization tool between the...

In the construction process of the giant project, because of each participant’s asymmetric and incomplete information and their pursuit of maximum interests, etc., the risk of cost control exists in the process of management. This article focuses on the owners facing cost management risk in the construction process of GB. First, it analyzes the behavior of the each project participant, and then...

earned value management (evm) is the process of integrating the time and cost management within the framework of project scope management. the earned value has provided methods for predicting the cost for projects. in large part, these methods have not been improved upon since their beginnings and remain unsubstantiated as to accuracy. in this direction, several mathematics formulas have been d...

the dynamic nature of projects and the fact that they are carried out in changing environments, justify the need for their periodic monitoring and control. collection of information about the performance of projects at control points costs money. the corrective actions that may need to be taken to bring the project in line with the plan also costs money. on the other hand, penalties are usually...

A cornerstone of software project management is effort estimation, the process by which effort is forecasted and used as basis to predict costs and allocate resources effectively, so enabling projects to be delivered on time and within budget. Effort estimation is a very complex domain where the relationship between factors is non-deterministic and has an inherently uncertain nature, and where ...
