Analysis on decision-making model of plan evaluation based on grey relation projection and combination weight algorithm

In military service joint operations, when there are more operational forces, more multifarious materials are consumed, the support is more complex and fuzzy, the deployment of personnel is more rapid, and the support provided by wartime military material support powers can be more effective. When the principles,requirements, influencing factors and goals of military material support forces are deployed in wartime, an evaluation indicator system is established. Thus, a new combined empowerment method based on an analytic hierarchy process（AHP） is developed to calculate the subjective weights, and the rough entropy method is used to calculate the objective weights. Combination weights can be obtained by calculating the weight preference coefficient error, which is determined by combining the cooperative game method and the minimum deviation into objectives. This approach can determine the grey relation projection coefficient and synthesize the measure scheme superiority to finally optimize the deployment plan using the grey relation projection decision-making method. The results show that the method is feasible and effective;it can provide a more scientific and practical decision-making basis for the military material support power deployment in wartime.

城市防灾减灾综合能力的定量分析

随着全球气候异变,灾害日益频繁,城市防灾减灾综合能力日益引起人们的关注。本文采用频率统计法、特尔菲专家咨询法以及理论与实际分析法对预选指标进行层层筛选,确定城市防灾减灾综合能力评估的指标体系。然后采用改进的层次分析法以及灰色投影关联法,提出了城市防灾减灾综合能力定量分析与评价的模型。最后,通过实地调查、收集数据,对天津市2005—2007年的城市防灾减灾综合能力进行定量分析。结果表明:2005、2006、2007年天津市防灾减灾综合能力指数为0.4593、0.5778、0.6178;理论分析和实地察看表明,该方法不仅对城市防灾减灾综合能力的评价是可行的、可靠的、客观的,而且能很好反映城市防灾减灾工作的现状,是适合中国城市进行城市防灾减灾综合能力定量计算与分析的方法。
