自动线结构系统的合理性,可根据对各种不同方案的经济效果进行比较来评价。一般情况下,用制造单件最小消耗作为标准: C_i+E_HK_i=min式中:C_i——i方案的单件日常费用(成本);E_H——基建投资的额定有效系数;K_i——i方案的基建投资率。自动线通常是由专用机床组成,它们的基型是成批生产的。在自动线中,并列工作的机床数量平均不超过3~4台。这些自动线的结构取决于给定的产品纲领、工艺过程和设备的组成。
The rationality of automated line structure systems can be evaluated based on a comparison of the economic effects of different scenarios. In general, the minimum cost of manufacturing a single unit is used as the standard: C_i + E_HK_i = min Where: C_i - i The daily cost per unit of the plan (cost); E_H - The effective rating of the capital investment; K_i - i The rate of infrastructure investment. Automatic lines are usually composed of special machine tools, their base type is produced in batches. In the automatic line, the number of parallel work of the machine does not exceed an average of 3 to 4 units. The structure of these automatic lines depends on the given product program, process and equipment composition.
