【摘要】 针对油气田开发方案的优选问题,提出了动态多指标决策法,在指标、方案两种因素的基础上,增加了时间因素,将决策论中的理想矩阵由二维扩展到三维,通过进行矩阵规范化、求其相对增长率,矩阵集结等,又将三维决策问题转化为二维决策问题来解决,最后由正负理想矩阵求解各方案的贴近度,得到最终决策排序结果,从而优选出油气田开发的最优方案。方法克服了以往只考虑指标属性值或指标增长率的弊端,具有很好的实用性。更多还原

【Abstract】 This paper provides the dynamic multiple of index decision making for oilfield to choose the best developing program It increases the time factor on the basis of target factor and program factor, and ideal matrix is expanded from two spaces to three spaces. Through carrying on matrix standardization, calculating rate of comparative growth, gathering matrix, etc , then the decision making problem is solved by transforming three - dimensional to two - dimensional, finally obtaining the close degree of all programs of plus & minus ideal matrix, and attain the sequence of the project, so as to select the best developing program. The method overcomes the former weakness that has only considered target attribute value or target increment’s rate, and it has good usability.更多还原
