RISK AND THE DESIGN ENGINEER: INDIVIDUAL AND COGNITIVE FACTORS' INFLUENCE ON SAFETY PERFORMANCE

海上设施的设计会增加建造和使用这些设施的工人的安全风险。在这项研究中，我们旨在调查设计师之间的差异如何影响设计师的判断质量，以及判断质量如何影响安装安全。在研究的主要阶段，我们将评估设计师之间的个体差异，设计师的判断质量，以及其他因素，超过300名设计师的样本。我们将评估表明设计师判断质量的因素(记忆力丧失、冒险决策)。为此，我们将要求设计师在一个工作周的四个阶段每天完成几次简短的评估。设计师将在掌上电脑上进行这些评估。我们预计将获得超过15,000份这样的评估。这样，设计师之间的判断质量指标会考虑到性能的周期性变化，而不是依赖于可能不准确的单次测量。然后，我们会将判断质量指标和设计师的个体差异与他们在研究期间所做设计的安全性联系起来。

The design of offshore installations can increase risks to safety of workers building and using these installations. In this research, we aim to investigate how differences between designers influence the quality of designers' judgement, and how the quality of judgement influences installation safety. In the main phase of the research, we will assess individual differences between designers, quality of designers' judgements, and other factors in a sample of over 300 designers. We will assess factors that indicate designers' judgement quality (memory lapses, risky decision-taking). We will do this by asking designers to complete brief assessments several times per day over four periods of one working week. Designers will make these assessments on palmtop computers. We expect to gain over 15,000 such assessments. In this way, the indicator of judgement quality between designers takes into account periodic variations in performance, rather than relying on a single-shot measurement that could be inaccurate.We will then relate indicators of judgement quality, and designers' individual differences, to the safety of the designs they were working on during the period of the study.
