The leading international standards for information security management, ISO/IEC 27001 and ISO/IEC 27002 originate from the UK, but are applied worldwide. This paper explores whether the processes of selection, implementation and use of these interrelated standards differ between China and Europe by studying cases of Chinese and European companies. Chinese companies face some additional problems with the standards but manage to get them successfully implemented in a short period of time. Main differences relate to governance and management of standard adoption. This study is innovative in the method used for standardisation research (comparative multi-case study), and the topic: implementation and impact of information security management standards.  相似文献

This article presents the quantitative eco-efficiency method developed for prioritising environmental investments in NOGEPA, The Netherlands Oil and Gas Exploration and Production Association involving all major oil and gas producers in The Netherlands. They are committed to a high level of environmental improvement in a Covenant with Dutch central government. Quantitative assessment of eco-efficiency in terms of cost per unit of environmental improvement requires the quantification of both costs and environmental impacts, each in a single indicator. The present study focuses on the development of a single environmental indicator for that purpose. The overall process for arriving at such an indicator has been structured according to ISO 14042 about the life cycle impact assessment. For the last step in this process, the establishment of weighting factors across environmental themes, a panel method has been chosen, involving as stakeholders the government officials involved, the industry experts and independent experts from scientific institutes.  相似文献

管理信息系统已深入到各行各业,但开发高质量的MIS远落后于计算机发展,由于系统设计缺陷及满足需求增长的不适应,给用户带来不便与损失,并缩短了系统使用寿命。为此,提出了基于非线性科学的管理信息系统构建思路:对系统信息进行统计自相似性分析,能对未来信息进行动态预测;对功能部分与整体进行自相似性分析,从而部分能有效地过渡到整体。  相似文献

Product life cycle (PLC) prediction plays a crucial role in strategic planning and policy definition for high-technology products. Forecast methodologies which can predict PLCs accurately can help to achieve successful strategic decision-making, forecasting, and foresight activities in high-technology firms, research institutes, governments, and universities. Over the past few decades, even though analytic framework strategies have been proposed for production, marketing, R&D (research and development), and finance, aiming at each stage of PLCs, forecast methodologies with which to predict PLCs are few. The purpose of this research is to develop a novel forecast methodology to allow for predictions of product life time (PLT) and the annual shipment of products during the entire PLC of multiple generation products. A novel two-stage fuzzy piecewise regression analysis method is proposed in this paper. In the first stage, the product life-time of the specific generation to be analyzed will be predicted by the fuzzy piecewise regression line that is derived based upon the product life-time of earlier generations. In the second stage of the forecast methodology, the annual shipment of products of the specified generation will be predicted by deriving annual fuzzy regression lines for each generation, based upon the historical data on the earlier generations' products. An empirical study predicting the life-time and the annual shipment of the 16 Mb (Mega bit) DRAM (Dynamic Random Access Memory) PLC is illustrated to validate the analytical process. The results demonstrate that two-stage fuzzy piecewise regression analysis can predict multiple generation PLT and PLC precisely, thereby serving as a foundation for future strategic planning, policy definitions and foresights.  相似文献

运用模糊的语言变量进行多属性事物的群体评价决策,即模糊信息多维偏好群决策。由于BOT项目的风险结构十分复杂,如何对BOT项目风险进行有效的分级管理显得十分重要。系统地分析了BOT全生命周期风险的内容与属性,运用模糊决策理论和多维线性规划模型,结合改进的Borda分值法,构建了BOT项目生命周期的模糊信息多维偏好线性规划风险评价模型。模型中既考虑了决策者意见的一致性,又兼顾了决策意见的差异性,为BOT项目风险管理和评价提供了新的思路。  相似文献

Luxury goods such as gemstones constitute a challenge for moving towards a sustainable society. From a purely bio-economic perspective, such goods consume planetary resources to provide a human “want” rather than a “need”. However, their extraction or manufacturing also provides important livelihoods for communities along the supply chain and hence contribute towards development outcomes. Comparing mined versus synthetic gems can provide consumers with important benchmarks on choice. The energy usage and emissions in mined versus lab-created diamonds was evaluated, based on industrial data, since these two factors are often a general indicator of environmental impact that can be useful in product comparisons. Depending on the process and the location of the mine, the data can be highly divergent and cannot be used as a singular measure of environmental impact. There is a need to develop life cycle analysis techniques from industrial ecology to conduct a detailed comparison of synthetic versus mined stones. Informed consumers could help to transition this luxury good towards a mix of mined and synthetic gems that best meet ecological and social metrics of sustainability.  相似文献

This paper investigates the link between a firm's process innovation (PI) and its segment productivity at different life cycles. The results show that business diversification is negatively associated with a firm's productivity, and further reveal that a firm's PI moderates the above relationship. In addition, the corporate life cycle literature builds blocks for this study to explain that the involvement of administrative costs varies across life cycles when diversified firms get mature and bigger. Our empirical evidence indicates that the potential costs of a complex organisational structure contingent on business diversification at a firm's mature life cycle could be alleviated by the conduct of process innovation. As process innovation at different life cycles may alter managerial incentive that leads to different firm performance, the managerial implication is that diversified firms should appropriately engage in process innovation to prevent unfavourable liability from the development of their businesses.  相似文献
