摘要： Upon starting of MRP processing, material information and product structure stored on a disk are extracted into a material information table and a product structure table, respectively, and the two tables are related with each other such that upon one level explosion in MRP, explosion to lower items can be performed only by designation of an address without retrieving component parts from a parent part. Further, a calendar day table and an operating day table are used to produce a composite calendar table. The composite calendar table is used for important date calculations. Moreover, upon registration into a key area of a management table of demand information contents at a plurality of positions of the key area are replaced with each other. And, upon extraction of the demand information from the management table, contents at a plurality of positions of the key area are replaced with each other. Consequently, upon ordering processing, the demand information can be extracted in a sorted order from the management table in a very short time.
摘要翻译：在MRP处理开始时，存储在磁盘上的材料信息和产品结构分别提取到材料信息表和产品结构表中，并且两个表彼此相关，使得在MRP中一级爆炸时，爆炸到较低的项目只能通过指定地址而不从父部分检索组件部分来执行。此外，使用日历日表和操作日表来生成复合日历表。复合日历表用于重要的日期计算。此外，在键区域的多个位置处的需求信息内容的管理表的关键区域的登记被替换。并且，在从管理表中提取需求信息时，将关键区域的多个位置的内容替换。因此，在订购处理时，可以在非常短的时间内从管理表以排序的顺序提取需求信息。

摘要： A machine tool control system is provided that controls a plurality of machining equipment by transferring, from a tool center, schedules for each machining equipment to a plurality of terminals which correspond to the plurality of machining equipment, respectively. The machine tool control system includes a controller for storing a plurality of schedules for the plurality of machining equipment. During operation, the system analyzes the current operating condition of the plurality of machining equipment through the respective terminals, and selects a schedule which is currently capable of being processed by each of the plurality of machining equipment from the plurality of schedules. The schedule that is selected is then transferred to each of the plurality of terminals corresponding to each of the plurality of machining equipment. A machining program converting system is also provided that converts an original machining program corresponding to one of the machining equipment into a compatible machining program for a substitutive machining equipment when the current operating condition of the machining equipment is determined to be in an overload condition or a trouble condition, and when it is determined that the original machining program is not compatible for the substitutive machining equipment.
摘要翻译：提供了一种机床控制系统，其通过从工具中心向每个加工设备分配对应于多个机械设备的多个端子来分别控制多个加工设备。机床控制系统包括用于存储多个加工设备的多个时间表的控制器。在操作期间，系统通过各个终端分析多个加工设备的当前操作状态，并从多个时间表中选择当前能够由多个加工设备中的每一个进行处理的调度。然后将所选择的日程传送到与多个加工设备中的每一个对应的多个终端中的每一个。还提供了一种加工程序转换系统，当将加工设备的当前操作条件确定为处于过载状态时，将对应于一个加工设备的原始加工程序转换为替代加工设备的兼容加工程序故障条件，以及当确定原始加工程序与替代加工设备不兼容时。
