Performance evaluation of process industries resilience: Risk-based with a network approach

Risk management can be defined as coordinated activities to conduct and control an organization with consideration of risk. Recently, risk management strategies have been developed to change the approach to hazards and risks. Resilience as a safety management theory considers the technical and social aspects of systems simultaneously. Resilience in process industries, as a socio-technical system, has four aspects of early detection, error-tolerant design, flexibility, and recoverability. Meanwhile, process industries' resilience has three phases: avoidance, survival, and recovery, determining the transition between normal state, process upset event, and catastrophic event. There may be various technical and social failures such as regulatory and human or organizational items that can lead to upset or catastrophic events. In the avoidance phase, the upset event is predicted, and thus, the system remains in a normal state. For the survival phase, the system state is assumed to be an upset process event, and the system tries to survive through the unhealthy process conditions or remains in the same state, probably with low performance. In the recovery phase, the system is supposed to be catastrophic, and the emergency barriers are prioritized to show the severity of the consequences and response time, leading to a resumption of a normal state. Therefore, a resilience-based network can be designed for process industries to show its inherent dynamic transition in nature. In this study, network data envelopment analysis (DEA), as a mathematical model, is used to evaluate the relative efficiency of the process industries regarding a network transition approach based on the system's internal structure. First, a resilience-based network is designed to consist of three states of normal, upset, and catastrophic events. Then, the efficiency of each industrial department, which is defined as decision-making units (DMUs), is evaluated using network DEA. As a case study, a refinery that is considered a critical process industry is assessed. Using the proposed model shows the efficient and inefficient DMUs in each of three states of normal, upset, and catastrophic events of the process and the projection onto efficient frontiers. Besides calculating the network efficiency, the performance of each state is extracted to precisely differentiate between DMUs. The results of this study, which is one of the fewest cases in the area of performance evaluation of process industries with a network approach, indicated a robust viewpoint for monitoring and assessment of risks.

Reasons for implementing ISO 14001 in Malaysia

Environmental management systems (EMS) have been introduced globally to reduce environmental degradation issues brought about by industrial development. The research discussed in this paper is aimed at identifying the benefits and motivations of the implementation of EMS in compliance with the International Organization for Standardization (ISO) 14001 standard in Malaysian industries by using the pairwise comparison method. Experts in EMS from the Scientific and Industrial Research Institute of Malaysia were invited to participate in the research panel. Based on the experts’ input, data analysis was carried out by using multi‐criteria pairwise comparisons. The findings showed the ranked benefits and motivations of the implementation of the ISO 14001 standard for businesses. The results can indicate to policy‐makers and business advisors how businesses can be encouraged to implement the ISO 14001.     

我国地下水环境管理现状及管理制度构建研究

在目前进行我国《水污染防治法》的修法工作中,发现地下水的相关责任由国务院多个部门负责,系统性差,协调难度大,存在工作性质与管理责任脱节的现象。因此,文章在总结梳理国内法律法规和相关管理规定及理清各部门管理责任的基础上,针对我国地下水的实际情况,提出完善我国地下水管理制度及建议。

GKS在国家水质管理信息系统中的应用

图形核心系统是开发图形应用软件的一组核心功能描述,它独立于设备和各种高级语言,自８０年代中期被ＩＳＯ正式批准为第一个计算机图形学国际标准以来,世界上各大计算机厂商纷纷推出ＧＫＳ不同级别的实现版本,广大用户也不断将自己的图形应用开发平台转向ＧＫＳ。本研究结合国家水质管理信息系统的需求,以ＧＫＳ为起点,完成了ＮＷＱＭＩＳ图形管理系统的设计与实施,有效地支持了其应用功能的实现。     

地理信息系统及其在上海环境管理中的应用

地理信息系统(GIS)在众多领域中已成为一个独立发展的新的前沿领域。上海于80年代末开始着手在环境保护与管理中开展了环境地理信息系统方面的应用研究,并建立《上海市环境地理信息系统》等几个不同层次与专题的环境管理与辅助决策信息系统。本文分析了上海环保局系统所建立的2个信息系统的技术特征,并对建立环境信息系统的一些问题进行了探讨。      

环境权益及其市场化代理制度

提出了一个以新制度经济学方法分析环境问题及其控制方式的理论模型,并据此提出了当前环境保护工作实现制度创新的思考,其逻辑思路是：由环境资源的稀缺性引起的用于满足人类生存需要和生产需要这两种环境功能之间的矛盾,外化为人类生存性和生产性两型环境权益的冲突;解决这个冲突的两种制度安排─市场和政府─都存在着各自的“失灵”,因此,需要设计和实施一种使两者结合起来的更高形式的制度安排,途径之一是建立和实施以“法律框架、公众参与、代理公司”为要素的“环境权益之市场化代理制度”。当前我国环境保护工作正面临着这种制度创新的契机。
