Model sustainability in DSS design and scenario formulation: what are the right scenarios?

A concept of the integrated approach in designing multidisciplinary decision support systems (DSS) based on agricultural scenarios for sustainable catchment management is discussed. A principle of holism underlying the integrated approach to DSS design is formulated. For a model to be viable and sustainable, it should be based on scenarios that are plausible and highly typical from the point of view of those 'doing' agriculture. Problems concerning principles of scenario formulation within the integrated approach are considered. A notion of 'prototype' scenarios based on 'joint venture' of modellers and stakeholders is proposed.     

Prevention through design: The effect of European Directives on construction workplace accidents

Workplace accidents still occur with distressing frequency, particularly in construction. Industrialized countries have become increasingly aware of this situation and have adopted policies to attempt to deal with this issue. Such policies have led to the development of new laws and regulations with a view to improving workplace conditions.This paper first analyzes policies regarding accident prevention in the European Union, as initially stipulated in the European Framework Directive 89/391/EEC, and more specifically in Directive 92/57/EEC, on the implementation of minimum safety and health requirements at temporary or mobile construction sites, concentrating on prevention through design. Whilst designers previously had some responsibilities for reducing risk under common law provisions in many countries, this directive was the first explicit legislation to enforce particular duties upon them. The adaptation of the provisions in this directive to the national legislation of EU member countries is also studied.The second section of the paper analyzes the incidence rate of workplace accidents in the construction sector in each country from the year when these regulations came into force until the present time. Based on the evolution of these accident rates, the paper postulates the extent to which European policies have contributed to accident prevention in construction. It is now more than a decade since this legislation has been in force which provides a suitable period for a reflective analysis on it is impact.     

危险化学品装卸运输一体化安全风险预警平台设计与研究

针对危险化学品装卸环节与运输环节安全事故频发,涉及监管部门较多,及危险化学品流转过程中多物态、跨地域、跨时空的特征通过调研和分析,得出运输介质不符、疲劳驾驶、超载、企业超资质营业、装卸操作不规范等是影响危险化学品装卸、运输环节的主要安全风险因素;另外,装卸、运输环节安全风险影响因素之间存在紧密的耦合关系。为更有效落实企业安全生产主体责任和政府监管职责,严格依据相关法律法规和标准,并融合互联网、物联网、人工智能、地理信息等新一代信息化技术和理念,设计并研究集危险化学品装卸与运输一体化的安全风险预警平台。目前该平台已在山东淄博上线试运行,取得了良好的运行效果,提高了该市危险化学品装卸运输过程本质安全水平,增强了政府危险化学品监管能力。
