The goal of my project was the creation of an automatic PCB (Printed Circuit Board) ordering concept in the MSE2 unit of the Bosch plant in Hatvan. The creation of this concept was only possible with the in-depth knowledge of the current system.

I started my project with doing research into the development of the material replenishment system of the MSE2 unit, and created process maps to visualize the different concepts. This was important because it made me understand why the system is implemented in its current form. I examined the differences between the northern and southern subsystems of the unit and discussed the possibility and the advantages of a standardized system in the MSE2 unit. This was important, because I had to understand the peculiarities of the subsystems in order to create the automatic PCB ordering concepts for both subsystems. I introduced the automatic component ordering system of the Bosch plant in Salzgitter, called Smart Replenishment Service (SRS), and discussed the expected effects of the implementation of SRS in the MSE2 unit.

I created the process map of the PCB handling within the plant, which had two purposes. First, it helped me find the problems in the current PCB handling process. I found seven greater or lesser problems in the process, and made suggestions for the improvement. The second purpose was to visualize the connections between my automatic PCB ordering concept and the different sections of the plant that are relevant to the PCB handling process. I created automatic PCB ordering concepts for both the northern and southern subsystems of the unit. I created flowchart diagrams to make them easier to understand. I also created a LabVIEW simulation for both concepts, which had two reasons. First, it is easy to create a user interface for my program in LabVIEW, which makes the presentation of my ideas to the MSE2 management easier. The other reason was that the simulations can be used as a software specification and can be shown to the professional software developers who are going to create the automatic PCB ordering software, which can be implemented in the MSE2 unit.

At the end of my project I discussed the possibility of the expansion of SRS to the whole unit and the necessary changes in the current system before the SRS can be implemented efficiently.
