摘要：Project cost management includes the processes required to ensure that the projects are completed using the approved funds. It generally involves some basic procedures, such as enterprise resource planning, cost estimating, budgeting and control. In addition, in implementation of different projects, various engineering processes may be considered relatively certain in many branches but it cannot be claimed that the design, measurement, classification, assessment or interpretation is performed without any error. The processes related to cost management, including cost estimates, are not an exception and the data used for this purpose may not have near decisive quality, which may present as uncertainty in the data. In the present study, the effects of cost uncertainties in design and implementation process of feasibility studies for mining projects have been discussed as a case study. In order to explain the role of uncertainties, their effects on cost estimates of studies has been examined using Monte Carlo simulation. The approach explored in this study leads to better and more realistic understanding of the effects of cost uncertainties in project cost management and thus contributes to presentation of more efficient approaches to manage the associated risks
