Selecting an effective project plan is a significant area in the project management. The present paper introduces a technique to identify the project plan efficient frontier for assessing the alternative project plans and selecting the best plan. The efficient frontier includes two criteria: the project cost and the project time. Besides, the paper presents a scheme to incorporate Directed Ac...

A large body of work exists in process industry supply chain optimisation. We describe the state of the art of research in infrastructure design, modelling and analysis and planning and scheduling, together with some industrial examples. We will consider two network design type problems in more detail and then draw some conclusions about the degree to which different classes of problem have bee...

This report is the result of a research project on a pavement management system that was preformed by the Transportation Division of Iran University of Science and Technology. Information used in the project was collected from 20 zones of the Tehran Municipality. Any maintenance and repair system for roads is normally compared of a number of general and coordinated activities in conjunction wit...

Planning and design procedure of an open pit mining project just can be started after ultimate pit determination. In the carried out study in this paper it was shown that the most important factor in ultimate pit determination and in consequence in the whole planning and design procedure of an open pit mine is the metal price. Metal price fluctuations in recent years were exaggerated and impose...

Introduction At a time when radio spectrum is a highly valued commodity and where environmental issues are high on the agenda of local planning authorities, it has become vital for network planners to determine the optimum network design to satisfy these demands. Accurately predicting propagation in highly cluttered environments, where local effects are dominant, is not a simple task. Using a m...

This paper presents two automatic cellular network design algorithms which determine the favourable positions of transmitters with respect to co-channel interference (CCI). The proposed methods are capable of maximizing the average CCI ratio in the planning region while optimizing the covered teletraac demand. Additionally, we investigate how the proposed algorithms can be extended for locating...

We are working on a common information model called UNIWBS which uses the work breakdown structure concept. UNIWBS is intended to support project information integration and project planning and control as well. By using the UNIWBS, we are also developing a conceptual knowledge-based expert system called DYNAPACK for generating planning, design, and construction work packages. DYNAPACK will be ...
