研究自动化车床管理的优化问题 ,首先假设车床出现故障时已完成的零件数作为参数 ,其服从正态分布 ,在此基础上 ,以更换刀具为决策变量 ,以生产零件的总费用为目标函数建立动态规划模型 ,利用计算机程序对检查问题逐一选取进行尝试 ,选取最优的检查间隔使得总费用最少 ,最后通过计算机彷真模拟结果吻合很好 . To study the optimization problem of automatic lathe management, we first assume that the number of completed parts of the lathe as a failure parameter, which is subject to normal distribution, on the basis of which the tool change is the decision variable and the total cost of producing the parts as the objective function Dynamic programming model, the use of computer programs to check the problems one by one to try, select the optimal inspection interval so that the total cost of the least, and finally through the computer simulation results are in good agreement.
