Process for determing possible configurations of machining plant

Abstract

A process is disclosed for determining the possible configurations of machining plants for controlling and / or planning the production of at least one product in a plurality of machining plants having each several machining modules. The process comprises the following steps: (a) a sequence of individual processing instructions is determined for each product and by means of these instructions a particular machining plant is selected and the processing steps to be carried out in the machining plants are defined; (b) possible configurations of the machining plant and the product machining time in the machining plant for each configuration are determined depending on the machining steps that need to be carried out; (c) information on the state of the machining modules in the machining plants is provided; (d) the configurations of the machining plant which are possible in the given state of the machining modules and the product machining time in the machining plant for each configuration are derived from the information on the state of the machining modules and the machining steps to be carried out.

Description

technical field [0001] The invention relates to a method for controlling a plurality of processing plants each having a plurality of processing modules for producing at least one product. Background technique [0002] Modern industrial production is often characterized by a high degree of automation. Especially in the semiconductor industry, a high degree of automation is absolutely necessary in order to be able to compete internationally. [0003] During the production process the product goes through a series of processing steps which are carried out automatically on the product to be processed by different processing equipment. For example, in the process of producing integrated semiconductors, products go through as many as 600 steps, a considerable part of which can be carried out in a clean indoor environment with highly specialized processing equipment. For this purpose, many identical processing plants are often grouped together in one processing area ("bay"). [...

Problems solved by technology

This problem is also made more difficult by the fact that not all existing equipment can be used

Due to maintenance or repair work, parts of processing equipment are often not available or their use is restricted, which must of course be taken into account in production control or production planning

[0009] Unfortunately, the hitherto used methods for production control pay little attention to the fact that often a part of the processing plant is unavailable or its use is limited due to maintenance or repair work, thus, given the maximum capacity of the processing plant and / or or the production cycle of different products often have imperfect production control or insufficient explanation
