Risk Management Plan in Large Urban Projects

One of the risks distinguishes urban projects from other projects is to purchase of property obstacles. The matter is of more significance in large projects. Issues with regard to possessing property obstacles, lack of accurate layout drawings for underground facilities and following probable changes in designs make it vital to have specific studies on risk management of such projects. So thi...

Scheduling Large and Complex IT Projects Using Sliding-Frame Approach

Many IT projects and software development projects are very complex and sophisticated involving a large coordinated team. Such projects are a constant part of the operations of software companies such as Microsoft, SAP, Oracle, Google, Yahoo, IBM, and others. Many other companies carry large software projects as part of their IT operations. As a result of the size and complexity of such project...

System Cost Modeling: Estimating Manufacturing Cost in Large Complex Systems+

This paper proposes a methodology, Systems Cost Modeling (SCM), to evaluate the cost of complex systems with a large number of individual components and subsystems. Simple characteristics associated with each component are used as inputs to parametric estimates of fixed and variable costs, as well as process use time of relevant resources. These estimates are then used to calculate individual c...

Estimating Software Projects Based On Negotiation

The Software Engineering community has been trying to get fast and accurate software estimations for many years. Most of the proposed methods require historical information and/or experts’ judgment. Because of that, the current methods are not suitable for novice developers or persons who do not know the company development capability. In order to help overcome such need, this paper proposes a ...
