Abstract

Currently, companies are trying to optimize production, even more so as the economic situation is gradually deteriorating in many countries around the world, which is currently caused mainly by the COVID 19 pandemic. A specific type of production is that on production lines, which are individual workplaces where various production and assembly operations take place. The aim of the article is to analyze the impact of the choice of the control method for the production process on the optimization of costs and the process. The subject of the research is the production of fire-fighting throttles on a production line that has three workplaces. The problem of waste on the production line was identified by direct measurements of time consumption at the individual workplaces and by using images of the working day schedule. The article compares three approaches to production line management and waste reduction. The first approach was based on counting the number of finished products on the production line. The second approach analyzed in detail the duration of the individual operations into which the workplaces were divided. In the third approach, a method of balancing workplaces was used, which brought time and cost savings. The achieved results, using different methods of production management, are analyzed in detail, and the conclusions evaluated. The article contributes a comparison of the achieved results of cost optimization through the course of production of fire dampers. The research results were applied in practice. The research used methods of industrial engineering in the field of ergonomics, technical and economic analysis, and production management. Visualization of hourly performances, downtimes and failures, execution of work procedures, Shop Floor Management and many others, are recommended as ways to implement waste elimination when using the methods of industrial engineering.

Introduction published maps and institutional affilThe theory and practice of industrial production have been dealing with the issues of loss elimination and labor productivity growth for several decades
It is possible to consider losses only in relation to each other. This is the basic knowledge of the loss analysis. It is conditioned by the very dynamics of the production process, which is often similar to sociological phenomena [2]
Based on 30 counts of the number of products produced per hour, the average initial hourly output on the production line was calculated to be 19 pieces of products per hour (Figure 4)

Summary

Introduction

The theory and practice of industrial production have been dealing with the issues of loss elimination and labor productivity growth for several decades. Wasted time has proven to be the biggest cause of losses, losses seem to arise differently. No loss is caused by a single reason. It is possible to consider losses only in relation to each other. This is the basic knowledge of the loss analysis. It is conditioned by the very dynamics of the production process, which is often similar to sociological phenomena [2]. Losses are divided into only a few main groups, such as production, administrative, financial, business losses, and those caused by external iations
