考察投资决策问题，从整体效率和整体效益兼顾的角度思考，提出兼顾整体效率和整体效益最优的数学模型（GEGBOM），基于模型离散形式的决策变量，并按照投资活动的效率值进行排序，提出一种改进的离散和声搜索算法，为满足最低期望产出和最高投资额约束，算法执行过程中进行和声修正策略，数值结果表明了模型及算法的合理性和有效性。

General Efficiency and General Benefit Optimal Model(GEGBOM) is represented when aiming at investment decision, both considering general efficiency and general benefit and simultaneously propose an improved Discrete Harmony Search Algorithm(DHS). In the algorithm, we design the special correction strate?gy of invalid harmony and new improvisation and pitch adjustment of harmony. Numerical results reveal that the proposed mathematical model more actual and the proposed algorithm DHS can find better solutions.
