风险系数决策法是以风险系数为决策手段的决策方法。它与其它风险决策技术相比,具有通俗、易懂、容易掌握和使用的特点。其数学公式是: W=∑G_jK_j/n=(G_1K_1+G_2K_2……+G_nK_n)/n W——决策方案的风险系数 K——某单项因素的风险系数 G——某单项因素的权值它的决策步骤是: 1.分析、确定影响决策课题的主要因素K_n 2.确定各单项K值先由决策者编制各因素好(有利)、一般、差(不利)的风险系数范围值,提交专家组成的评估组征求意见,然后根据专家意见确定单项K值。单项K一般按下表取值:
Risk coefficient decision-making method is a risk factor as a decision-making method of decision-making. Compared with other risk decision-making techniques, it has the characteristics of being popular, easy to understand, easy to grasp and use. The mathematical formula is: W = ΣG_jK_j / n = (G_1K_1 + G_2K_2 ...... + G_nK_n) / n W - the risk coefficient of the decision-making program K - the risk coefficient of a single factor G - the weight of a single factor It The decision-making steps are as follows: 1. Analyze and determine the main factors that affect the decision-making task K_n 2. Determine the individual K values The decision makers should first prepare the range of risk coefficient values for each factor that is good (favorable), fair, bad Composed of assessment group for comments, and then determine the individual K value based on expert advice. Individual K generally according to the following table value:
