AI-assisted Production Planning





Sequence planning in manufacturing has been done manually up to now, and the complexity of taking all the framework conditions
into account is constantly increasing.





Research and development of an AI application for optimised sequencing using
product and production data.




Added Value

The usable output is optimised and thus the added value is increased by saving time in the manufacturing process.

Air conditioning and ventilation technology, components, devices and system technology: Westaflex is a German family business that has been providing architectural building services and air ducts since 1933. Solutions for a better climate and simplified construction made of aluminium, stainless steel and premium plastics. For every type of building and pipe, there are ventilation systems in many shapes and materials, in different diameters and grooves, so that the systems can be flexibly combined and adapted to the requirements. Accordingly, many different set-up processes are required in production, which in turn requires precise planning. To ensure that everything runs smoothly and as efficiently as possible, the sequence of orders must be planned precisely before production. 

KI-gestützte Fertigungsplanung bei Westaflex

Sequence planning determines the production sequence of individual orders with the aim of making the production process lean, time-saving and thus efficient. Currently, the sequence planning of orders at westaflex is still done manually, for example using spreadsheets or analogue planning boards, and not automatically. Factors such as machining, set-up and delivery times, product specifications, material or the reduction of effort must be taken into account individually. This is very cumbersome to implement: Orders and sequences of machines cannot usually be simply shifted without having to manually adjust the rest of the planning.

Data analysis and AI make for intelligent production planning

The goal is therefore to optimise the sequence planning of production orders with the help of artificial intelligence. For this purpose, a wide variety of data, for example ERP data and real-time data from production, are being evaluated in order to derive indications for optimal machine occupancy and to use these findings for sequence planning.

For this purpose, a data platform is being developed as a web-independent on-premise solution. Order data, resource data, process data, tool/maintenance data, logistical data and monetary data are brought together on the data platform and processed for the AI application. The data platform thus represents an IT infrastructure equipped with interfaces for the plant’s internal data and the data from the AI application. The solution found is implemented and tested with real data, optimised and validated.


For the AI Marketplace, this project results in valuable solutions and building blocks in the field of production system development, which also benefit other companies facing similar problems or goals. Westaflex primarily expects this project to optimise the usable output and thus increase
the added value by saving time.

AI-assisted Producibility Analysis

A set-up process in an automated manufacturing process that is optimized with the help of AI and replaces the previously manual “teaching” – this is the core of a project by düspohl Maschinenbau GmbH and the Fraunhofer IEM. In addition, the probable producibility of new product specifications is to be assessed automatically.

AI-assisted Diagnosis

At present, vehicle diagnosis in a workshop requires comprehensive automotive knowledge and involves a great deal of work. Hella Gutmann’s aim is therefore to develop an AI application for AI-supported diagnosis and identification of potentially defective vehicle components on the basis of historical vehicle data (e.g. fault codes or sensor readings) and to integrate a further variety of data sources (e.g. invoice data, repair information etc.).

Intelligent Product Monitoring

The goal of Ubermetrics’ project is an AI application that extracts relevant information from unstructured or semi-structured texts (e.g. online ratings, complaint emails, service reports, complaint reports), analyzes it and makes it systematically available to a developer. The application can be used, for example, in the context of targeted optimization of system components.

Integration of AI in Computer Aided Design (CAx)

Artificial Intelligence has the potential to fundamentally change the way we work and operate. CLAAS GmbH & Co. KGaA, an internationally active manufacturer of agricultural machinery, has recognised this potential and is testing a special use case for the integration of AI in Computer Aided Design (CAx) in the AI marketplace together with the Fraunhofer Institutes IEM and IPK.

AI-assisted Service Engineering

How can service technicians be optimally supported? A pilot project by Diebold Nixdorf Systems together with Fraunhofer IOSB-INA is dedicated to this question. The aim is to develop an AI application that reads and analyzes service and sensor data from ATMs in the field. Based on this, differentiated repair instructions for service technicians are to be generated. An existing service platform will serve as a database.
