Functions and failures: how to manage technological promises for societal challenges

Technological promises are becoming part of the way in which scientific and technological communities try to attract the attention of stakeholders, aiming at legitimation, reputation, and funding. Not all promises, however, become reality. With the increase in the use of promises comes the risk of disillusion and cynicism, which may affect negatively policy-makers and the public opinion. The paper suggests that the introduction in the field of S&T and innovation policy of a tool commonly used in engineering fields aimed at identifying and measuring all possible failures of a proposed technology. Instead of focusing on the magnitude of promises, it suggests that a useful perspective can be gained by placing systematic attention to the negative side, i.e. all reasons why a given technology may fail to deliver the promises. The paper develops the methodology, presents a case study, and illustrates the benefits of using it in policy-making.     

集装箱货运链的非传统安全风险研究

集装箱货运链非传统安全风险防范问题已经引起了欧美发达国家海关极大的重视,作为国际贸易大国,该领域的研究在我国尚处于起步阶段.从海关监管角度出发研究集装箱货运链非传统安全风险非常有必要而且意义重大.文章从集装箱运输全过程出发,提供了一个简单的风险分析模型,通过分析集装箱运输网络的每个节点,预防集装箱运输链潜在的安全风险.根据该模型可形成集装箱货运链非传统安全风险的评估结果,为海关进行集装箱货运链风险管理提供依据,帮助解决运输网络中监管资源的有效分配问题.而今后的研究,除进一步完善海关风险分析外,还要致力于先进高效监控技术的研发.集装箱运输链是一条复杂的长链,涉及许多利益相关人和监管部门,安全高效的集装箱运输体系的构建需要学术界、运输产业、政府部门、科技产品生产商的共同参与.

Total efficient risk priority number (TERPN): a new method for risk assessment

Safety is one of the most important issues in modern industrial plants and industrial activities. The Safety Engineering role is to ensure acceptable safety levels of production systems, not only to respect local laws and regulations, but also to improve production efficiency and to reduce manufacturing costs. For these reasons, the choice of a proper model for risk assessment is crucial. In this context, the present research aims to propose a new method, called Total Efficient Risk Priority Number (TERPN), able to classify risks and identify corrective actions in order to obtain the highest risk reduction with the lowest cost. The main scope is to suggest a simple, but suitable model for ranking risks in a company, to reach the maximum effectiveness of prevention and protection strategies. The TERPN method is an integration of the popular Failure Mode Effect and Criticality Analysis (FMECA) with other important factors in risk assessment.
