Abstract:Linear programming with fuzzy-numbered Cost Coefficients,include of Single-objective and Multi-objective problems,is a important content in fuzzy decision makings.In this study,we give a solution to fuzzy single- objective linear programming problems with triangular fuzzy-numbered cost coefficients.The objective cost of fuzzy multi-objective linear programming problemsis hard to measure for it being a vecter with fuzzy number.So we focus on it in this paper.
