Abstract [en]

Introduction:

The project took place at Metsä Tissue AB Pauliström Mill in Småland to study and understand the company’s production system with focus on identifying existing bottlenecks and improving the efficiency of converting line-1 with the advent of the Toyota Production System, organizations and industries have continuously adapted several systematic methods, related to lean production to achieve a more efficient, waste free and cost effective production. One of such methods is the value stream mapping. This project, attempts to comprehend and analyze the bottlenecks experienced on a particular production line at Metsä Tissue AB Pauliström Mill, the converting line-1, for the Lambi 6 pack product family.

Purpose:

The project aims at studying the current state, and existing practices of Metsä Tissue’s production system, with focus on improving the efficiency and performance of converting line-1, by doing a comparison with converting line-2, using value stream mapping, and making suggestions for improvement by creating a futuristic state of converting line-1, using the principles of lean production.

Method:

To study Metsä Tissue AB Pauliström Mill’s production system, practical work in form empirical data was collected, by means of statistical analysis, calculations, observations and time measurements such as: cycle time, change overtime, transport time, available work time and takt time. Other data collected includes, production forecast, production schedule, delivery time, frequencies, number of available workers etc. The data collected was then analyzed against existing theory. The theoretical framework was constructed with regard to the main subject areas which are lean production and value stream mapping. The methodology used was a case study with a qualitative method and quantitative data gathering, with an interview conducted. The planned case study methodology coalesces both theoretical and empirical approach. Data collected during interviews with the production manager and shop floor workers, and observations of the converting lines, constituted the data needed to actualize the value stream mapping method. The value stream mapping method has been applied to construct the current state map of the converting line-1, and identify the wastes.

Conclusion:

The most critical areas of waste identified on the converting line-1 from achieving the current state map are the waiting time and the transportation time. From the current state map, it is identified that the speed on converting line-1 is less than that of converting line-2 because of the variance in the waiting time and transport time, one of the courses being that the logsaw on converting line-1 is older than that of converting line-2, hence a need for replacement. Also, for the company to maintain its lean statues, sustain its competitive advantage, and stay in tune with the dynamic technological advancements, Metsä Tissue AB Pauliström Mill should adopt an electronic visual display, pay more attention to the use of kaizen to improve the QDB (Quality Data Base), update its 5S practices, and constantly use value stream mapping to evaluate their performance.
