Purpose – The purpose of this paper is to discuss an integrated decision analysis framework for the investment justification of implementing alternative information and communication technology (ICT)-based logistics systems in the construction industry so as to enhance the decision-making process in selecting the best alternative. Design/methodology/approach – An integrated framework is proposed that is composed of a set of interrelated evaluation and analysis techniques that allow the identification and quantification of costs, benefits and risks involved in implementing ICT systems to mitigate problems that hinder the efficient operation of construction logistics. Such techniques include decision trees and multi-attribute decision-making under uncertainty that can be applied to the logistics planning of any new build construction project. Findings – The probabilities of providing benefits vary among the alternatives, and the probabilities will replace the uncertainties surrounding the impacts of the alternative ICT systems in addressing the identified construction logistics problems with chance events so as to estimate the expected cost of each alternative with respect to each selection attribute. Practical implications – This paper shows that it is almost certain that the analysed alternative ICT system will provide benefit because its probability of benefit is almost equal to 1. Originality/value – The framework captures the existing problems of logistics in construction process, potential solution that can address the problems through the implementation of ICT systems and the decision-making process in the selection of appropriate ICT solution. The output of the framework will help to make knowledge-based decision in selecting the best ICT system for addressing construction logistics problems.
Purpose -The purpose of this paper is to discuss assessment of the satisfaction levels of different members of a construction project team as a basis for meeting the needs of the client. Design/methodology/approach -An integrated framework is proposed that enables a collaboration of construction clients and project participants based on the recognition of the satisfaction requirements of every participant represented in the project team. The framework is developed to prioritise the satisfaction attributes of flexible number of construction clients and project participants, and enables the integration of these participants and their satisfaction attributes using mathematical and engineering techniques. Findings -The framework can be applied at the different phases of the project life cycle. In addition, the satisfaction levels of construction clients and the project participants can be enhanced by focussing on the values of their satisfaction attributes and improving the integration of the project team. Practical implications -The paper shows that a collaboration of construction clients and project participants based on the recognition and acknowledgement of each participant and their requirements is essential to improving project satisfaction in the construction sector. Originality/value -The framework captures and analyzes the level of integrated project team satisfaction. The outcome of the study will improve understanding the satisfaction requirements of every client and participant represented in a given construction project team.
The theft of plant and equipment is a significant problem in the construction industry. In the United Kingdom, it is estimated that the cost of theft of construction plant is around £500 million. However, the focus of attention has been the effects of plant theft to the construction industry rather than the causes. Determining the significances of the causes of plant theft will enhance the development of appropriate strategy for mitigating theft. Therefore, the purpose of this paper is to present an analysis that was carried out to measure the significances of identified factors related to the theft of construction plant. The contribution indices and probabilities of contribution of the factors were derived in the analysis. The analysis shows that the highest contributing factor to plant theft is site location.
This paper examines the various internal security challenges confronting Nigeria in the 21st century. The paper adopts historical method and content analysis to investigate how the abysmal failure of the poorly formulated and ineffectively implemented National Security Policy has hitherto exacerbated internal security challenges in Nigeria. The paper further attempts a critical review of major internal security challenges hitherto confronting the country; such as the Niger Delta crises, kidnapping in the South-East geo-political zone, Jos crises, Boko Haram crises and crises by Fulani Herdsmen in the Northern part of Nigeria. The result of the analysis shows that these internal security challenges have not only been difficult to address by the National Security Policy, but have also impacted negatively on the country's desired socio-economic development in the 21st century. The paper, therefore, recommends among others, the need for a careful review of the Nigeria's National Security Policy that will not only be integrative/comprehensive in outlook, but will also take cognizance of some domestic factors that are currently responsible for internal security problems in the country; such as unemployment, inequality, poverty, fraudulent electoral process, corruption, skewed federalism, porous nature of the Nigeria’s borders, sabotage among politicalelites, bad governance, religious intolerance, citizen-settler controversies, among others.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
