Abstract

The article describes the SAPFORD-based methodology for reconciling and restructuring the schedules of workshops and sections in the event of failures in the work of production and supply services. An efficient method is proposed for constructing a unified production schedule for a plant, optimized by the criterion of minimizing costs associated with servicing work in progress and penalties for delays in order fulfillment. The task of planning custom-made production is decomposed into subtasks of distributing work to workplaces with specified parameters within acceptable time frames. For each work, the target function of the dependence of the increase in the production price on the amount of delay or premature execution of the work is set and the time of its execution is calculated for which the delivery date of the product is not violated and the “idling” time of the part before the operation starts is minimal. The criteria for subtasks are coordinated by the method of mutual penalties, the essence of which is that the competing jobs in the queues penalize each other with increments of their estimates when letting the competitor take the lead. The first in line is the work with the smallest sum of its own criteria and penalties for delaying competitors. If there are production delays in one shop, the estimates of delayed orders are recalculated and the work in other shops is reordered. The results of the recalculation of the shop operation plans are reflected in the shop nomenclatures of priority works. An example of the solution is given.

在定制生产中同步车间的操作

摘要

本文介绍了基于SAPFORD的方法，用于在生产和供应服务工作失败的情况下协调和调整讲习班和各部分的日程安排。提出了一种有效的方法来构建工厂的统一生产计划，并通过最小化与进行中的维修工作相关的成本以及延误订单履行的罚款的标准来进行优化。计划定制生产的任务分解为子任务，这些子任务是在可接受的时间范围内将工作分配给具有指定参数的工作场所。对于每项工作，确定了生产价格上涨对作品的延迟或过早执行的依赖关系的目标函数，并计算了执行时间，在该时间内不违反产品的交货日期，并且“空转”开始操作之前的零件时间最少。子任务的标准是通过相互惩罚的方法来协调的，其实质是当让竞争者领先时，队列中竞争的工作会相互增加估计值，从而相互惩罚。排在第一位的是其自身标准和对延误竞争者的罚款最小的作品。如果一个车间有生产延迟，则重新计算延迟订单的估计值，并重新排序其他车间的工作。车间作业计划的重新计算结果反映在优先工作的车间术语中。给出了解决方案的一个例子。
