Assessment of delay factors in construction of sport facilities through multi criteria decision making

Abstract

The construction of sports facilities widened drastically as the number of sport events gradually increased during the last two decades in the global environment. The requirements of International Federations to host these sports events impact the construction of these facilities. Construction complexity, budget and time constraints and pressure from the project stakeholders play an important role on delivery time of such facilities. The aim of this paper is to identify and evaluate the most significant delay factors that affecting the delivery of sport projects worldwide. From previous literatures and one-to-one meetings with technical experts, a list of 37 delays attributes were identified. These factors were categorised in 8 groups and distributed through an online questionnaire portal to sport facility professionals. 101 completed responses were collected and analysed through different ranking approaches and multi criteria decision making methods (Relative Importance Index (RII), Spearman’s Rank Correlation, T-Test and Analytical Hierarchy Process (AHP). The analysis of AHP concluded that “low level of consultant experience”, “low level of contractor experience”, “shortage of construction materials” and “difficulties in financing the project by contractor” were the most critical delay factors, while “delays related to contractor capabilities” was the most critical delay group. The value of this paper is to provide the industry professionals with the most significant delay factors in construction of sports facilities to take proper managerial actions to reduce delays.     

Accounting for variability in individual hierarchical clinical trial data

Meta-analytical approaches have been extensively used to analyze medical data. In most cases, the data come from different studies or independent trials with similar characteristics. However, these methods can be applied in a broader sense. In this paper, we show how existing meta-analytic techniques can also be used as well when dealing with parameters estimated from individual hierarchical data. Specifically, we propose to apply statistical methods that account for the variances (and possibly covariances) of such measures. The estimated parameters together with their estimated variances can be incorporated into a general linear mixed model framework. We illustrate the methodology by using data from a first-in-man study and a simulated data set. The analysis was implemented with the SAS procedure MIXED and example code is offered.
