objectives: behavioral-based safety is a term used to describe the prevention of accidents, injuries and loss in the workplace. an effective behavior-based safety program relies on engaging employees to understand how unsafe behaviors lead to injuries and how to eliminate them from the workplace. this paper examines behavior-based safety program in a massive construction site. methods: for this...

Recognizing the value of information sharing among supply chain partners, a growing number of firms have expressed keen interest in jointly creating customer demand, managing business functions and leveraging the strength of their supply chain partners. In particular, such interest sparked the rapid development and implementation of collaborative planning, forecasting and replenishment (CPFR) t...

This paper presents a Computer-Based Training (CBT) tool that relies on an integration of Virtual Reality (VR) and Case-Based Reasoning (CBR). It is an application that handles past cases represented in Virtual Reality (VR) and aims at providing a framework for the development of computer-based instructional applications. A prototype has been developed as part of this research and is used to pr...

the present study aimed to investigate the characteristics of occupational accidents and frequency and severity of work related accidents in the construction industry among iranian insured workers during the years 20072011.the iranian social security organization (isso) accident database containing 21,864 cases between the years 2007-2011 was applied in this study. in the next step, total accid...

fuzzy logic is one of the concepts that has created different scientific attitudes by entering into various professional fields nowadays and in some cases has made remarkable effects on the results of the practical researches. however, the existence of stochastic and uncertain situations in risk and accident field, affects the possibility of the forecasting and preventing the occurrence of the ...

One of the foremost aims of component technology is the replacement of large monolithic applications with sets of smaller components, whose particular functionality and interoperation can be adapted to users' needs. However, the adaptation mechanisms of component software are still limited. Most proposals concentrate on adaptations that can be achieved either at compile time or at link time. Cu...

The aim of component technology is the replacement of large monolithic applications with sets of smaller software components, whose particular functionality and interoperation can be adapted to users’ needs. However, the adaptation mechanisms of component software are still limited. Most proposals concentrate on adaptations that can be achieved either at compile time or at link time. Current su...

Commercial-Off-The-Shelf (COTS) software components are being used within complex safety-critical applications. However, to use them with confidence, it is necessary to ensure that potential failures of the COTS component does not contribute to system level hazards. To this end, we have established a contract-based approach to capture the application-specific safety requirements, and correspond...

Current best practice is that the acceptability of safety-critical software-based systems should be justified by a clear and defensible argument. This paper examines the structure that such an argument might take with regard to the allocation of system safety requirements to components, in particular software component requirements. A model solution is presented for a general class of control s...

Case-based reasoning systems applied to safety-critical environments justify specific measures to ensure that the assistance provided is not dangerous to human life. Taking example on a case-based reasoning system developed for medical decision-support in stem cell post-transplant long-term follow-up, this article stresses the importance to differentiate between reliability and safety, and how ...
