Abstract [en]

This paper focuses on the later part of the wood processing chain in wood industry: the wood product manufacturing. Wood product manufacturers are facing many challenges e.g. due to the high variability of the raw material. Waste and rework are prevalent, resulting in high manufacturing costs. Each processing step in the manufacturing affects material utilization and cost efficiency. The proportion of the material cost and waste in most wood products are high. The challenge for wood product manufacturers is to make profit and remain competitive when on one side they need to execute the processes at the lowest cost and within shortest time and on the other side deal with a highly variable raw material. Therefore, wood product manufacturers need to consider their manufacturing process with emphasizes on the raw material consumed. The purpose of this paper is to examine the direct –and indirect influences of the material on the wood product manufacturing process in terms of productivity and efficiency. The direct influences aims at examining the impact of consuming raw material with different properties on the manufacturing process, while the indirect influences examine process-related aspects affecting the material’s influence on the manufacturing process. This paper is based on a case study at a Swedish interior wood product manufacturer. The first phase of the study compares between two wooden panels with different material properties. Results show that solid, knotty raw material with higher moisture content results in lower efficiency than finger-jointed, knot free material with lower moisture content. The second phase of the study examines the indirect influences and shows that material handling is one of the key process-related aspects that need to be considered.

Abstract [en]

The wood products industry is important to Sweden's prosperity, and is currently facing several challenges by increased global competition. To avoid the gradual decline of the industry’s contribution to the country’s revenues and employment opportunities, the Swedish wood products industry needs to increase the proportion of the raw material that is refined. New and efficient manufacturing technologies are essential to support this development. The implementation of automation in manufacturing needs to be supported by conscious and well-defined strategies. However, currently, there is a lack of knowledge regarding automation decisions in this industry. Therefore, the purpose of this thesis is to increase knowledge regarding which aspects should be taken into account when automation decisions are considered in the wood products industry. Three research questions are addressed: (1) What is the current state of manufacturing operations in the wood products industry? (2) What are the potential opportunities for automation in the wood products industry? And (3) What challenges can arise from automation in the wood products industry?

The results presented in this thesis are based on four research papers. The first paper provides an overview of the current state of manufacturing operations in the wood products industry. The second paper examined the impact of the raw material on manufacturing operations in the wood products industry. The third paper assessed how the levels of automation in manufacturing impact operational performance. The fourth paper examined automation opportunities and challenges to gain a better understanding of the reasoning behind automation decisions in the industry.

In general, it is concluded that automation decisions in the wood products industry tend to be based on “gut feeling” and previous experience with automation rather than well-defined decisions and strategies. This is due to inadequate knowledge and familiarity with automation technologies in manufacturing. Furthermore, the findings showed that different aspects of manufacturing interact and impact each other. For this reason, it is essential to take into account other aspects of manufacturing when considering automation decisions.
