Abstract
The Pareto diagram is a powerful tool for identifying the significant factors influencing objects, processes, services, etc. In the production sphere, it is very suitable for analysis of defects and their impact. In this work are summarized the types of defects that occur in the production of headrest covers for car seats. Analysis was made of both the frequency of occurrence of defects and the financial losses from them. The research is done on the whole production range (all projects) proceeded in a given month, on product families and on specific products. The three defects with the highest frequency of occurrence were identified. For them, additional study was conducted to determine the impact of the type of used material on internal scrap calculated as an expense in euros.Based on the obtained results, recommendations are made for improving the work and its results.
Highlights
The Pareto principle states that for many events roughly 80% of the effects come from 20% of the causes
Used is the Pareto diagram, which is a cumulative curve giving the relationship between the cumulative frequency and the individual factors ranked according to the frequency of their occurrence or degree of influence
This article presents the results of a study, which aims to analyse the defects that occur in the production of headrest covers by using the Pareto diagram
Summary
The Pareto principle states that for many events roughly 80% of the effects come from 20% of the causes. This article presents the results of a study, which aims to analyse the defects that occur in the production of headrest covers by using the Pareto diagram (chart). The research was not focused on the amount of scrap as a number of defective products, but on the projects that generate the largest financial losses.
