约翰·里奇威(John Ridgway)关于安全至关重要系统金宝博官方
约翰·里奇韦(John Ridgway)在纽卡斯尔大学(University of Newcastle)的泰恩大学和苏塞克斯大学(Sussex University)学习了物理学,然后从事软件工程职业。作为该职业的一部分,他在智能运输系统(ITS)领域工作了28年,代表其雇主执行软件质量管理和系统安全工程角色金宝博官方Serco运输系统金宝博官方。In particular, John provided design assurance for Serco’s development of the Stockholm Ring Road Central Technical System (CTS) for the Swedish National Roads Administration (SNRA), safety analysis and safety case development for Serco’s M42 Active Traffic Management (ATM) Computer Control System for the UK Highways Agency (HA), and safety analysis for the National Traffic Control Centre (NTCC) for the HA.
John is a regular contributor to the Safety Critical Systems Club (SCSC) Newsletter, in which he encourages fellow practitioners to share his interest in the deeper issues associated with the conceptual framework encapsulated by the terms ‘uncertainty’, ‘chance’ and ‘risk’. Although now retired, John recently received the honour of providing the after-banquet speech for the SCSC 2014 Annual Symposium.
卢克·穆尔豪瑟(Luke Muehlhauser):您对安全工程的专业知识和兴趣的本质是什么?
约翰·里奇威(John Ridgway):我不是专家,我不想以自己的身份转移自己。相反,我是一个谦虚的从业者,也是一个退休的人。在接受过物理学家的教育之后,我从事软件工程师的职业生涯,最终升任英国Serco Transportation Systems的高级职位,在该系统中,我负责确保建立和实施旨在促进和展示完整性的流程的建立和实施金宝博官方计算机系统。金宝博官方最初,有金宝博官方关系统(道路交通管理系统)并不被认为是与安全有关的,因此,交付产品中缺乏完整性的不仅仅是商业或政治意义。但是,在英国公路局采购部门内的安全政策改变了安全政策之后,我认识到,如果要继续作为批准的供应商,我的组织内将需要改变文化。
If there is any legitimacy in my contributing to this forum, it is this: Even before safety had become an issue, I had always felt that the average practitioner’s track record in the management of risk would benefit greatly from taking a closer interest in (what some may deem to be) philosophical issues. Indeed, over the years, I became convinced that many of the factors that have hampered software engineering’s development into a mature engineering discipline (let’s say on a par with civil or mechanical engineering) have at their root, a failure to openly address such issues. I believe the same could also be said with regard to functional safety engineering. The heart of the problem lies in the conceptual framework encapsulated by the terms ‘uncertainty’, ‘chance’ and ‘risk’, all of which appear to be treated by practitioners as intuitive when, in fact, none of them are. This is not an academic concern, since failure to properly apprehend the deeper significance of this conceptual framework can, and does, lead practitioners towards errors of judgement. If I were to add to this the accusation that practitioners habitually fail to appreciate the extent to which their rationality is undermined by cognitive biases, then I feel there is more than enough justification for insisting that they pay more attention to what is going in the world of academia and research organisations, particularly in the fields of cognitive science, decision theory and, indeed, neuroscience. This, at least, became my working precept.
