Abstract
Abstract The aim of the paper was to improve service processes carried out by Knorr-Bremse Systemy Kolejowe Polska sp. z o.o. Particularly, emphasise unnecessary movements and physical efforts of employees. The indirect goal was to find a solution in the simplest possible way using the Muda ideology. In order to improve the service process at the beginning was executed the process mapping for the devices to be repaired, ie. brake callipers, electro-hydraulic units and auxiliary release units. The processes were assessed and shown as Pareto-Lorenz analysis. In order to determine the most time consuming process. Based on the obtained results use of a column crane with articulated arm was proposed to facilitate the transfer of heavy components between areas. The final step was to assess the effectiveness of the proposed solution in terms of time saving. From the company perspective results of the analysis are important. The proposed solution not only reduces total service time but also contributes to crew’s work comfort.
Highlights
In order to increase manufacturing and service efficiency, companies strive to optimise all processes related to their activities
In order to reduce the probability of service interruptions implementation of a column crane with the articulated arm was considered
The column crane with articulated arm would allow to operating throughout the hydraulic area due to the large operating zone of the arm
Summary
In order to increase manufacturing and service efficiency, companies strive to optimise all processes related to their activities. The article presents the results of the improvement of service processes in Knorr-Bremse The autors present their method, which include seven steps. To improve service processes in Knorr-Bremse the Muda ideology was used to reduce waste of motion and waiting and transportation. Knorr-Bremse manufactures, sells and maintains the electro-hydraulic brake system components "Clean" operations are related to assembly interfere are undesirable and should be separated in the future of further development of the Local Service Center should be separated Both zones contain new parts to be exchanged, machined parts for reuse, equipment to analyse, repaired devices ready for transfer to the warehouse
