一类区间约束的模糊线性规划问题解的存在性和稳定性

On the Existence and Stability in the Solution of Fuzzy Drogramming Problems of Inter-valued Constraints

在考虑当参数中心变化时 ,具有对称三角形模糊数的模糊线性规划解的稳定性问题。引入一种新的约束(即区间模糊约束 )的概念 ,这种约束比传统的线性规划的约束更广泛性。在新的约束下 ,模糊线性规划问题的解仍具有稳定性。

The paper takes into account the problem of symmetrial triangular fuzzy linear programming which occurs during the changes of the center of parameters.A new concept of interval-valued constraint is proposed.It is more extensive than the traditional one.Under the new constraint,the stability in the solution of fuzzy linear programming is obtained.
