摘要
针对连续型区间灰数间大小排序的问题,提出了一种连续型区间灰数排序方法。首先构建了区间灰数与实数间大小比较的点可能度函数,然后通过对区间灰数的标准化,在区间上对点可能度函数进行积分,并利用积分性质求解并给出了两个区间灰数间在六种不同位置关系下大小比较的可能度函数表达式。最后利用区间灰数的排序函数,对许昌市8家民营企业核心竞争力进行排序评价。结果表明,4家民营企业核心竞争力较强,2家民营企业核心竞争力一般,2家民营企业核心竞争较弱。加强企业的管理、创新企业的技术和提高企业家素质是增强民营企业核心竞争力的途径。
Aiming at the sorting algorithm for interval grey number of continuous type,this paper discusses a sorting algorithm for continuous interval grey number based on possibility degree.Firstly,the point possibility degree function used to offer the comparison between the interval grey number and real number is constructed.Secondly,the point possibility degree function of the comparison between every possible true value of one interval grey number and the other one is given through the standardization of interval gray number.Thirdly,according to integral properties,this paper solves the possibility degree function and gives the function expression of six different positional relationship between the two interval grey number.Finally,evaluating the core competency for the fourteen companies in Xuchang city by sort function.It is found that 8enterprises' core competency is strong,2enterprises' core competency is normal and 2enterprises' core competency is weak.Private enterprises can increase their core competency by strengthening enterprise management,technology innovation and improving entrepreneur quality.
