本文讨论了向量最优化问题的ε-有效解的存在性和标量化．同时引进了ε-真有效解的概念，在锥-次类凸的假设条件下，建立了这种解的一个标量化定理．

In this papers the existence and scalarization for the ε-efficient solution in vector optimization problem (VMP) are discussed. We introduce a new kind of ε-efficient solution in (VMP), namely, the ε-proper efficient solution. A scalarization
