# Integrated Multilevel Production Planning Solution According to Industry 5.0 Principles
## 4 Results--IMPS (Integrated Multilevel Planning Solution)
### Operational Planning Activity/Workplace Level  
Operational planning is the lowest level among all levels and consists of a detailed scheduling of production activities to follow the schedule defined earlier. For the scheduling of production activities to work, it is necessary to receive information from production in real time. This information should include parameters such as the percentage of scrap, the percentage of the completed norm, the number of parts completed, the productivity per workplace, etc. The company used a tool called Smart Digital Assistance (SDA) to bring information and services into production. SDA (Figure 6) is a very simple setup for real-time communication with production. For the implementation of the SDA integral system, it is necessary to ensure the necessary prerequisites in production as well. It is necessary to install computers in workplaces and connect them appropriately to the network. These prerequisites can have significant costs. In the future, with a 5G network, the connection itself could potentially be much simpler, but currently it relies on a LAN or Wi-Fi signal. The first step is to check the availability of the signal in production to determine the exact positions for the workstations. Next, it is necessary to clearly define the requirements for computers. It is necessary to consider the conditions at the workplace itself, starting with how much space there is, whether there is a possibility of damage to the computer/screen (if there are moving objects in the environment), and what kinds of data are displayed on the screen. In our case, it was concluded that it was necessary to ensure that the screens were protected by an armor because in all places there was a possibility of falling objects or damage from the transfer of materials and the like. It was necessary to analyze the place where the screens and computers (portals) would be located--fixed places (tables), brackets attached to the wall, carts, lickers at workplaces, and so on. The company tested fixed and trolley portals. Carts were found to be challenging because it was necessary to define how and when it would be possible to provide time to charge the battery. It is important to consider whether the workers need to visualize the drawings and, if so, what kind of drawings they are. Drawings showing elongated components where it is necessary to see

Workers who worked with simpler drawings where it is enough to show one detail, which can be achieved by zooming in on the region, can use smaller 27\" or 42\" screens. During the test period, the workers were satisfied with the sizes initially selected. It was initially estimated that it would be ideal to use touch screens. When working with 2D drawings and documentation, this solution turned out to be very good. However, for workplaces where it is necessary to use 3D models and make additional measurements (elevations) on them, a mouse is needed. When it was not necessary to make additional elevations, the workers were satisfied with using only the touch screen and the hybrid keyboard on the screen. The basic functionality was to replace paper plans with plans on portals. Saving on paper is not the main motivation but rather the availability of the latest approved version of the documentation (from the PLM or DMS system) and the availability of additional drafts or information in all shifts (even when the archive or office workers are not available). From experience with other similar locations, the approaches were very different. Considering the goals, it is logical that the system on such screens must be adapted in such a way that workers automatically receive the necessary and adapted information for their workplace and that they can easily access other data.
