Problem

In the KEP project, which has been carried out by the company Alius d. o. o. for several consecutive years, errors have been systematically occurring, which they wanted to limit by introducing additional control measures. Limiting these errors is important from several perspectives. The most important is certainly the economic perspective, through which the justification of the project over the years is even possible. ** Throughout the assignment, it was shown that the economic justification of the project can be further increased.** The second perspective, due to which multi-year collaboration on such a project is important and due to which there was a need to limit the errors that occurred on the project, is the ** sustainability perspective**.

This represents for the company Alius in the first phase continuous collaboration with its business partner, the company Brüggen, and consequently in the second phase this also brings Alius additional trust from its partner and new orders. For demonstrating the ability to achieve the quality requirements that are set in the KEP project by the client is extremely important for the strength of collaboration between both companies. The company Alius, by raising product quality, gains the trust of its customer, who consequently gains references with their customers due to the high-quality products they offer in their markets.

Of course, with such an extensive project, it is not possible to completely eliminate errors, as they are influenced by several factors over which the project contractor has no influence or can only influence them indirectly. Thus, the input material, which is the responsibility of the client, has a very important influence. The input material itself plays a key role in the quality of the final product. Both participants in the project, both the company Brüggen and the company Alius, are very well aware of this, and therefore the company Brüggen is increasing emphasis on input material control from year to year.

This is consequently also reflected in the part of the project carried out by Alius. The second extremely important factor that has a great influence on the course of the project itself is the logistics of material to the production line itself.

Solution and Method

For the course of the project, material logistics is extremely important, as timely delivered material can also shorten the time required for product manufacture. The project contractor Alius d. o. o. can only influence both of the above-mentioned factors indirectly. Its area of influence is concentrated on the production part of the project.

By pointing out errors in the input material and by pointing out delays in installation components to the production line, it can contribute to a faster course of production itself and to reducing errors due to installed poor or damaged material that appear during final product inspection. However, Alius could and also did influence and limit errors at workstations during the production process itself, which was also the purpose of this diploma thesis.

Results

**In the introductory part of the diploma thesis, three basic theses were established, which were also confirmed throughout the assignment. ** 1. With a properly selected quality control method, the number of products in the desired quality can be raised to the required level or even above it. o With the Pareto diagram, they correctly determined the location and cause of error occurrence and thus could also eliminate them, which consequently led to raising the production process to the required level. 2. With proper, continuous and timely training of workers, we can reduce or prevent the occurrence of errors. o Through employee training, they achieved both a reduction in existing errors and the occurrence of new ones.

3. By reducing the number of errors in production, productivity is improved and the number of hours for eliminating unforeseen errors is reduced, and thus the costs of non-quality are also reduced. o When they managed to eliminate the causes of error occurrence, they thereby reduced the number of errors on the product itself. Consequently, the number of hours for eliminating these errors was reduced, and thus the costs arising from non-quality were also lowered. The methods used were transferred to the project, where they proved to be successful. Unfortunately, the duration of the project is limited and it will conclude at the end of the year.

If next year the company Alius is entrusted again, it will be necessary to reassemble the team for automobile manufacture. As for several consecutive years, at least 40% of the team will most likely be completely new, workers will need to be retrained and errors that were addressed in this work will need to be eliminated again. Therefore, it is all the more important that when the project is restarted, the measures that are described are introduced immediately, as this can limit the number of errors on the product from the very beginning.
