Title: METHOD AND DEVICE FOR PLANNING A PRODUCTION PROCESS FROM A SPECIFICATION AND BASIC FUNCTIONS
Abstract:
The invention relates to a method for planning a production process of a product composed from multiple sub-products in a production system (SYS) consisting of multiple technical components (D1, D2, D3). The current state of the production system (SYS) and semantic information (ASM,SKM,PO,PR) are stored in a knowledge base (KB) or a database. The semantic information comprises data on the production system and on basic functions (SK) which can be executed in the form of encapsulated programs by the components (D1, D2, D3) in the production system, on sub-products which can be processed in the production process, and on production steps which can be carried out in the production process and dependencies thereof which can be represented as a directed graph with edges and nodes. The following steps are carried out in the method: a) reading a digital specification (SPEC) for producing a specified product; b) planning a production process for the specified product on the basis of the read specification (SPEC) using a planning program (PE) and an inference program (RE), wherein the planning program (PE) generates the production process in the form of a sequence of basic functions (SK) using information derived by an inference from the knowledge base by means of the inference program (RE); and c) controlling the execution of the sequence of basic functions (SK) by means of an execution program (EE).
