Development of a risk measure as a sustainable project selection criterion

SUMMARY

Sustainable decision-making requires consideration of technology, ecology, and the social and political infrastructure of society. While it may never be possible to identify with certainty what is sustainable and what is not, an attempt has been made in this paper to formulate a measure that permits one to compare the performances of project alternatives with respect to risk. An algorithm is presented for the evaluation of a risk criterion that can be used with other criteria in the process of selecting project alternatives. The intent of the risk criterion is to involve project stakeholders in the process of quantifying the risks associated with different project alternatives.     

灾害救援中基于民众心理感知的应急物资多阶段分配问题研究

为有效解决在保证高效完成救援任务的同时考虑受灾民众行为,进而提高灾民对救援处置效果的满意度问题,结合行为运筹学相关理论和不公平厌恶理论,提出民众对于应急物资到达时间的风险感知度量模型,以及民众对于所得到的应急物资数量的公平满意度度量模型,构建基于灾民心理感知的应急物资多阶段调度模型,解决应急物资到达时间风险感知、物资分发数量公平满意度等多目标下的调配决策问题;设计基于蚁群优化思想的求解算法。研究结果表明:通过实例分析对比验证了模型在提升灾区民众对于应急物资分发策略满意度方面的有效性。     

基于成本收益理论的井场作业人员不安全行为决策分析

为有效制定油气田井场作业人员不安全行为的防范措施,降低事故发生可能性,基于成本收益理论建立油气田井场作业人员的行为决策模型,通过仿真计算定量分析了不同影响因素对不安全行为产生的影响程度。结果表明:正向激励和负向激励对不安全行为的降低幅度为21.8%,17.2%,负向激励和监督力度共同作用下不安全行为可降低44.8%。油田企业在保证利润的前提下应优先提升HSE奖励水平,合理控制罚金水平的同时加大管理监督力度,从而有效减少作业人员不安全行为的发生,保障企业的安全生产。     

Multi-objective Programming and Social Welfare Analysis of Rural–urban Land Conversion Decision-making

Abstract

Rural–urban land conversion is an inevitable phenomenon in urbanization and industrialization. And the decision-making issue about this conversion is multi-objective because the social decision maker (the whole of central government and local authority) has to integrate the requirements of different interest groups (rural collective economic organizations, peasants, urban land users and the ones affected indirectly) and harmonize the sub-objects (economic, social and ecological outcomes) of this land allocation process. This paper established a multi-objective programming model for rural–urban land conversion decision-making and made some social welfare analysis correspondingly. Result shows that the general object of rural–urban land conversion decision-making is to reach the optimal level of social welfare in a certain state of resources allocation, while the preference of social decision makers and the value judgment of interest groups are two crucial factors which determine the realization of the rural–urban land conversion decision-making objects.     

Local communities' participation in decision-making processes through planning and budgeting in African countries

Community participation and community based management are topical themes in current policy and discussion revolving around decision-making processes especially those dealing with natural resources management.This review shows that while governments have accepted the need to either cede or devolve control and management of natural resources to the local communities,the communities are not part and parcel of the planning and budgeting which are crucial in decisionmaking.Communities were seen to be more involved in the implementation of natural resource management programs but lacked ownership of the projects.This causes lack of commitment to the programs and at times hostile reaction from the communities.The communities are always at the receiving end when it pertains to losses in the exchange.Community participation was shown to be effective when the local population is involved not as co-operating users but as natural resource managers or owner managers.     

基于LEC法的煤矿安全投资决策

利用基于作业条件危险性评价法(LEC)的综合评分决策法,对煤矿安全培训、通风除尘设施投资的合理性进行评价,分析了系数的取值过程并得到综合评分决策的合理度值.结果表明,基于LEC的综合评分决策法对煤矿安全投资合理度进行分析决策,具有直观、量化的优点,在一定程度上解决了安全投资规模难以把握的难题,可以对煤矿企业的安全投资提供合理化建议,便于管理者决策.     

非常规突发事件应急决策方法研究

为深入研究非常规突发事件应急决策方法,提高对非常规突发事件的应对能力,调查研究基于应急预案、范例推理和智能规划等3种非常规突发事件的应急决策方法,对比分析这3种方法的特点。研究发现:这3种方法都可以在一定程度上为非常规突发事件提供辅助决策,但是基于智能规划的应急决策方法更适于非常规突发事件复杂的决策环境,有较大发展潜力。然后针对该方法,提出一些需要深入研究的开放性课题。     

基于范例推理的灾害性地震应急物资需求预测研究

基于范例推理(CBR)理论,利用最近相邻法和粗糙集理论搜索相似度最高的主震历史范例,分析各主要物资需求量的影响因素,预测当前范例主震期应急物资需求量。通过序贯决策,采用马尔科夫预测模型预测余震类型,进而搜索余震历史范例,预测余震期应急物资需求量。以"玉树"地震为例,运用该方法估算地震发生后食物类、生活用品类、药品类、工程机械类的需求量。
