It is shown that such problems can be reduced to a linear semi-infinite programming problem. The relations between optimal solutions and extreme points of the linear semi-infinite program are established. A cutting plane algorithm is introduced with a convergence proof, and a numerical example is included to illustrate the solution procedure.}, number={10}, journal={COMPUTERS & MATHEMATICS WITH APPLICATIONS}, author={Fang, SC and Hu, CF and Wang, HF and Wu, SY}, year={1999}, month={May}, pages={63–76} }

By applying fuzzy set theory, we “soften” the original problem with fuzzy relation and denote it by VĨ. Then the solutions which satisfy the variation inequality to some degree μ, 0 ⩽ μ ⩽ 1 are searched with minimum relaxation. According to the proposed existence theorem, an approach derived from the concepts of single objective mathematical programming problems for solving the VĨ is proposed to find its fuzzy solution set.}, number={1}, journal={EUROPEAN JOURNAL OF OPERATIONAL RESEARCH}, author={Wang, HF and Liao, HL}, year={1998}, month={Apr}, pages={198–203} }
