    Shop floor management systems in case of increasing process variation
    ( 2018)
    Schliephack, Wolf
    Most of the German production companies use shop floor management systems, which are built on holistic production systems. The basic assumption for shop floor management in cyber physical production systems (CPPS) is that companies want to use the special capabilities and knowledge of their employees for improvements in their production. This chapter analyses the state‐of‐the‐art of industrial solutions on digital performance boards and to inspect their ability to promote these methods and services or to define differences. At the same time the specific need of these services should be investigated in industrial environment. Regarding this the actual process variation and the benefit of the respective use of single services should be tested and evaluated. Referring to the basic role of workers in the digital factory, the chapter describes two fundamental scenarios: the ""specification scenario"", and the ""automation scenario"".

    Test of industrial Internet of Things. Opening the black box

    The smart factory paradigm follows a self-control philosophy and carries an ecosystem of cyber physical systems and internet of things services. They are interacting dynamically. CPSs can enter the ecosystem and leave it after they are no more required or obsolete. In fact, the behaviour and potential risk related to one IoT component can be a blackbox for the user but it has direct influence in the stability of the manufacturing. Interoperability issues can just stop the production process and creates high economic losses. It becomes much more critical if the CPSs are part of a wider network. From industrial experiences, such risks are underestimated. It is necessary to provide technologies on top of the existing protocol compliance tests to provide a transparent view to decision makers. The paper provides an initial concept on potential approaches derived from a German national project for IoT test solutions and labs (IoT-T).

    Customers demand for individualized products leads to a large variety of different products in small series and single-unit production. A high flexibility pressure in product creation is one result of this trend. In order to counteract the pressure, the information steadily increasing by Industry 4.0 must be made available at the workplace. Additionally, a better exchange of information between product development, production planning and production is necessary. The improvement of individual systems, like CAD, PDM, ERP and MES, can only achieve this to a limited extent. Since they mostly use systems from different manufacturers, the necessary deeper integration of information is only feasible for SMEs to a limited extend. The presented control desk helps to ensure a more flexible product creation as well as information exchange. It captures information from different IT systems in the production process and presents them integrated, task-oriented and oriented to the user's mental model, e.g. information of the production combined with the 3D model of product parts, or information about product development on the 3D model of the production. The solution is a digital 3D model of the manufacturing environment, which is enriched by billboards for a quick information overview and web service windows to access detailed MES and PDM information. By this, the level of abstraction can be reduced and reacts to changed requirements in the short term, making informed decisions. The interaction with the control stands utilizes the touch skills of mobile and fixed systems such as smartphones, tablets and multitouch tables.
