Postningsoptimering vid sönderdelning av fura vid Säters Ångsåg

Abstract: The aim of this project is to optimise the sawing patterns used for sawing Scots pine at Säters Ångsåg AB. The thesis has a theoretical approach and does not claim to be fully applicable in a practical point of view. The input used in this project is last year's sales volumes and prices of sawn products. The input of the timber is collected from the database "VIOL". The results show that there is a great potential in optimising the sawing patterns compared to the sawing patterns used today. By increasing the volume of high value sideboards and decreasing the volume of low value centreboards the contribution margin can be increased. The results show that the conclusion of increasing the volume of sideboards and decreasing the volume of centreboards not is price sensitive. The price of sideboards can fall up to 20 % without any changes in optimal volume. Hence; the quality of the sideboards can decrease without changing the optimal volumes of sawn products. The result of this project show that a SEK 10 million increases in total contribution margin can be obtained from optimising sawing patterns.
