Despite the increasing number of accidents in process industry caused by human error, there are still too few efforts devoted to this area. This is mainly caused by people's tendency to overestimate human's capability in interacting with their working environment and moreover by the unavailability of reliable analysis methods. Because of the current lack of adequate methods, human factors (HF) analysis is not widely performed in process industry. Some HF techniques developed in the process industry were examined regarding their practical applicability and were unfortunately proved to be unsuitable for an elaborate HF analysis. Therefore, a new approach was developed, which provides a systematic way in performing a qualitative HF analysis to achieve a safer operation and decrease the number of human failure events. HF consideration during the design of a process plant is the key to minimize accidents caused by human error in process industry. Thus, an approach to incorporate HF into design phase is described in this article, which can help achieving a safer operation as early as possible with minimized costs. © 2009 American Institute of Chemical Engineers Process Saf Prog 2009 相似文献

The study aimed to examine the relationship between alternative approaches towards problem solving/design teaching (structural
or functional), students’ mental modeling of the design process, and the quality of their solutions to design tasks. The structural approach emphasizes the need for an ordered and systematic learning of the design process stages, while the functional approach emphasizes the teaching and study of design functions (rather than stages). Participants were 80 seventh graders,
divided into two groups, who were taught a unit on technological problem solving by either approach in the course of 14 classes
(21 h) during a semester. Before, during and after the design process of a technological solution the students represented
their perception of the design process. The results for both groups were analyzed in terms of: (a) types of models generated;
(b) changes in type of models along the learning/design process; (c) defining characteristics of the design process models.
Significant differences between the groups’ models were found for most variables examined. The functional approach was more
effective than the traditional structural approach for supporting the construction of holistic, flexible, and effective mental
models of the design process of technological solutions. 相似文献
