Towards the Generation of Setup Matrices from Route Sheets and Feedback Data with Data Analytics
(2018)
The function or department of production control in manufacturing companies deals with short-term scheduling of orders and the management of deviations during order execution. Depending on the equipment and characteristics of orders, sequence dependent setup times might occur. In these cases for companies that focus on high utilization of their assets due to long phases of ramp up and high energy costs, it might be optimal to choose sequences with minimal setup time times between orders. Identifying such sequences requires detailed and correct information regarding the specific setup times. With increasing product variety and shorter lot sizes, it becomes more difficult and rather time intense to determine these values manually. One approach is to analyse the relevant features of the orders described in the route sheets or recipes to find similarities in materials and required tools. This paper presents a methodology, which supports setup optimized sequencing for sequence dependent setup times through constructing the setup matrix from such route sheets with the use of data analytics.
In today´s turbulent market, the way data are used in production is one of the key aspects to maintain or increase a manufacturing company´s ability to compete. Even though most companies are aware of the advantages of collecting, analyzing and using data, the majority of them do not exploit these fully. Thus, IT systems and sensors are integrated into the shop floor in order to deal with the current challenges, leading to an overwhelming amount of data without contributing to an improvement of production control. Because of developments like digitization and Industry 4.0, there is an innumerable amount of existing research focusing on data analytics, artificial intelligence and pattern recognition. However, research on collaborative platforms in traditional production control still needs improvement. Therefore, the main goal of this paper is to present a platform based closed loop production control and to discuss the relevant data. The collaborative platform represents the basis for a future analysis of high-resolution data using cognitive systems in order for companies to maximize the automation of their production. A use case at the end of the paper shows the potential implementation of the findings in practice.
Im vorliegenden Positionspapier wird das Konzept einer Produktionsregelung beschrieben. Zunächst wird der Begriff der Produktionsregelung erläutert. Durch die kontinuierliche Erfassung und Überwachung des Ist-Zustands und den Abgleich mit den Soll-Werten werden Anpassungen am Produktionssystem möglich.
Zur erfolgreichen Einführung dieses Konzepts sind zwei Dimensionen in folgenden vier Handlungsfeldern zu entwickeln:
• Hochauflösende Auftragsüberwachung,
• datengestützte Produktionssteuerung,
• Production-Analytics,
• Produktionsregelung.
Für produzierende Unternehmen ergeben sich hieraus folgende Vorteile:
• Höhere Transparenz über betriebliche Abläufe
auf dem Shopfloor,
• Erhöhung der Reaktionsfähigkeit (geringe Reaktionszeit, bessere Lösungsqualität) der Fertigungssteuerung,
• Steigerung der Stamm- und Plandatenqualität durch kontinuierlichen Abgleich,
• Steigerung der logistischen Leistungsfähigkeit des Produktionssystems.
