TL;DR: In this article, the authors present several improvements to basic GAs and demonstrate how these improved GAs reduce computational costs and significantly increase the efficiency in searching for optimal solutions for time-cost optimization problems.
Abstract: Time-cost optimization problems in construction projects are characterized by the constraints on the time and cost requirements. Such problems are difficult to solve because they do not have unique solutions. Typically, if a project is running behind the scheduled plan, one option is to compress some activities on the critical path so that the target completion time can be met. As combinatorial optimization problems, time-cost optimization problems are suitable for applying genetic algorithms (GAs). However, basic GAs may involve very large computational costs. This paper presents several improvements to basic GAs and demonstrates how these improved GAs reduce computational costs and significantly increase the efficiency in searching for optimal solutions.

TL;DR: In this article, the use of information technology as an enabler is rarely sufficient to cause process change, and a combination of IT, organisational and human resource enablers and a total quality management based philosophy are required for the effective redesign of business processes.

TL;DR: In this paper, the authors suggest that construction processes need to be carried out concurrently and people in volved in the project need to integrate into a unified development process by becoming a multi-disciplinary team.
Abstract: The construction industry has been suffering from low productivity and poor performance In an attempt to improve its performance, industry practitioners and researchers have looked at the manufacturing industry as a point of reference and a source of innovation Conse quently, the industry has acquired and adapted the Concurrent Engineering (CE) approach to manufacturing, to construction Concurrent Con struction (CC) The motivation for importing a CE approach to construction is presented in this paper To assist in overcoming the industry's poor productivity and performance, this paper suggests that construction processes need to be carried out concurrently Furthermore, people in volved in the project need to be integrated into a unified development process by becoming a multi-disciplinary team Thus, all downstream aspects of the design and construction process and non-value adding activities (waste) can be considered throughout the design stage of the project
