摘要
数学期望在解决不确定因素的问题中有着重要应用,是反映随机变量总体取值的平均水平的一个重要的数字特征,在管理决策中有许多问题可以直接或间接地利用数学期望来解决。对数学期望进行了详细介绍,通过讨论射击游戏、储蓄收益率和产品价格策略等具体案例,从数学期望的内涵出发,对数学期望在管理决策中的应用进行了分析。
Mathematical expectation plays an important role in solving the problem of uncertain factors and it is an important numerical feature reflecting the average level of the total value of random variables.There are many problems in management decision that can be solved directly or indirectly by mathematical expectation. This paper introduced the mathematical expectation in detail,and analyzed the application of the mathematical expectation in the management decision by discussing the specific cases such as shooting game,saving rate and product price strategy. The study also analyzed the application of mathematical expectation in management decision.
