在企业的实际生产过程中,要探寻最佳质量点并不是一件十分容易的事情。我们已经知道质量成本各项目间的相互关系,正如质量成本最佳值模式图(见图1)所示,该模式图清晰地表达了两大类质量成本(即内部故障成本加外部故障成本这一类与鉴定成本加预防成本另一类)之间的相互关系,且明确显示出质量成本总额曲线上有一最低值。很显然,在不增加生产总成本,又能满足符合性质量标准水平的条件 In the actual production process of the company, it is not easy to find the best quality point. We already know the interrelationship between quality cost items, as shown in the quality cost best value model diagram (see Figure 1). This model diagram clearly expresses two major types of quality costs (ie, internal fault costs plus external fault costs. The correlation between one type of identification cost plus the prevention cost and the other) clearly shows that there is a minimum value on the total mass cost curve. Obviously, the conditions for meeting the quality standards of conformity without increasing the total cost of production
