Hannover Messe: How artificial intelligence is helping make food production smarter

Claudia Ehrlich Pressestelle der Universität des Saarlandes

    Food production is a complex process involving the monitoring of raw materials, supply chains, market prices and much more besides. Access to smart data can help producers make their processes both greener and more cost effective. But this data can also be used to create additional revenue streams – something that will be demonstrated at this year’s digital edition of Hannover Messe by a research team led by Wolfgang Maaß of Saarland University and the German Research Center for Artificial Intelligence (DFKI). In their ‘Evarest’ research project, the team turns proprietary data into a commodity that can be traded securely without disclosing any intellectual property or trade secrets.

    What is next year’s harvest of cocoa beans or strawberries going to be like? When should we place an order and how much should we buy? How many sausages will be sold in November? How are commodity prices for grain, olive oil or meat going to develop and what quantities are going to be available and when? Food producers who have reliable answers to these questions can anticipate future demand and plan their production capacity more precisely. This can mean, for example, controlling production volumes so that they avoid overproduction at certain times of the year. A research consortium led by Wolfgang Maaß, Professor of Business Informatics at Saarland University, is showing how smart data can be used by food producers to yield reliable business forecasts.

    ‘Food production generates vast amounts of data, much of which has so far gone unused. That data represents unemployed capital. Using our data platform we can identify and establish relationships between production data sets. Once these data sets have been linked, analysed and evaluated, they can provide concrete recommendations for action whenever key production decisions need to be made,’ explains Wolfgang Maaß. While the individual data sets are essentially just columns of numbers and of little predictive value, when taken together this vast database can offer valuable operational insights. ‘The point of the exercise is not to disclose legitimately confidential industrial secrets or the operational know-how that makes a product unique. The data we use is anonymized operational data of the sort that accrues during production, such as sensor data, statistical information or data on quantities or volumes,’ says Maaß.

    He sees huge potential in this data, not least how it can be used to combat overproduction and to help achieve climate goals. ‘Food production generates almost one third of global greenhouse gas emissions. At the same time, millions of tons of food are destroyed every year. That damages the climate and results in higher costs. Data-driven predictive production planning offers producers the opportunity not only to invest in their public image, save costs and generate revenue through data production, but also to protect the climate,’ explains Professor Maaß.

    By establishing a data marketplace, Maaß and his research team want to use this new level of data transparency to create additional revenue streams for producers and manufacturers. ‘Companies retain ownership and control of all of their data, but they can use the Evarest platform to offer some of their data for sale to third parties. With daily transactions totalling billions of dollars on the international goods and commodities markets, the value of these data products is correspondingly high,’ says Maaß. Electronic contracts provide legal security in terms of precisely what and how data can be used, so that the data owned by each producer is safeguarded from misuse and from being used or transmitted inadvertently.

    ‘We want to help food data acquire its own intrinsic value and to make it into a tradable commodity,’ explains Professor Maaß. Companies that make their data available to the Evarest platform can not only transform production data into an additional source of revenue, they can also help build a system that benefits all stakeholders. ‘The more data we have available, the more effective we can make production and transport processes, we can also explore and analyse market potential and can uncover early on any market constraints or barriers that may be operating,’ says Maaß.

    The data platform that the research team has developed enables food producers to retrieve information that is fact-based and sector-specific. The synopsis and the recommendations generated by the system provide users with an array of parameters that can be adjusted to optimize their production processes. When a producer is interested in a specific question, the platform draws on a broad range of data from a diverse array of relevant sources, including, for example, sensor data from the producer’s own manufacturing and transport operations, general data such as weather forecasts or price indices, and plant or equipment data from other companies. Using artificial intelligence, machine learning algorithms and digital technology the data is automatically processed and linked, which involves analysing the production data from a particular company, comparing it with data from other producers and then combining the results with the outcomes from other analyses.

    The ‘Evarest’ research project has received €2.3 million in funding through the ‘Smart Data Economy’ technology programme sponsored by the German Federal Ministry of Economics and Energy. The research consortium involved in the project includes the German Research Center for Artificial Intelligence DFKI, Saarland University, the enterprise software company Software AG, the Institute for Industrial Management (FIR) at RWTH Aachen University, the agricultural market information consultancy Agrarmarkt Informations-Gesellschaft AMI and the chocolate manufacturer Lindt & Sprüngli AG. Associated partners are the German Institute of Food Technologies (DIL) and the Federation of German Food and Drink Industries (BE).
