Empirical investigation of construction safety management activities and performance in Australia

The construction industry seems to suffer from a general inability to manage workplace health and safety to a level where an achieved improvement in safety performance by a way of pro-active measures can result in zero accidents. This paper investigates the effectiveness of safety management activities as currently adopted by Australian contracting organisations. A safety management survey has been conducted of contracting organisations operating in the State of Queensland, Australia. Based on a research model depicting statistical analysis techniques, a safety management index reflecting the intensity of level of safety management activities has been developed to provide a means whereby individual organisations can be assessed and graded on their safety management commitment and attitudes. The paper reports on a detailed empirical analysis carried out to examine the relationship between the intensity of safety management commitment and the overall safety performance, pro-activeness and record.     

A framework for dependability engineering of critical computing systems

This paper presents a development model focused on the production of dependable systems. Three classes of processes are distinguished: (1) the system creation process which builds on the classical development steps (requirements, design, realization, integration); (2) dependability processes (i.e. fault prevention, fault tolerance, fault removal and fault forecasting); and (3) other supporting processes such as quality assurance and certification. The proposed approach relies on the identification of basic activities for the system creation process and for the dependability processes, and then on the analysis of the interactions among the activities of each process and with the other processes. Finally, to support the development of dependable systems, we define for each system creation activity, a checklist that specifies the key issues that need to be addressed with respect to each dependability process.
