Abstract

The aim of this study was to compare the volume yields and contribution margins in the production of clear finger-jointed boards using lower quality raw materials from four suppliers. The study is based on production statistics from 2005 to 2007 and has been carried out in cooperation with a company which manufactures clear finger-jointed boards for mouldings. The raw material was side-boards of Scots pine (Pinus sylvestris L.) with dimensions of 32 by 175 mm2. The four raw material suppliers are geographically distributed in different places in Central Sweden. Parallel with the study, a tool for production follow-up has been developed, to make it possible for the company to continuously follow-up its raw material suppliers.

The results of the study show that the cheapest raw material gives the highest clear wood volume yield and the highest contribution margin.

Zusammenfassung

Ziel dieser Studie war es, die Volumenausbeuten und die Bruttogewinne bei der Herstellung astfreier keilgezinkter Bretter aus Brettern geringerer Qualität von vier Lieferanten zu vergleichen. Die Studie wurde auf Grundlage von Produktionsstatistiken der Jahre 2005 bis 2007 in Zusammenarbeit mit einer Firma durchgeführt, die astfreie keilgezinkte Bretter für Schreinerarbeiten herstellt. Als Rohstoff dienten Seitenbretter aus Kiefernholz (Pinus sylvestris L.) mit den Abmessungen 32 × 175 mm2. Die vier Rohstofflieferanten stammten aus unterschiedlichen Gegenden in Zentralschweden. Parallel zu dieser Untersuchung wurde ein Programm zur Produktionsverfolgung entwickelt, das der Firma eine kontinuierliche Rückverfolgung der Herkunft der verwendeten Bretter ermöglicht.

Die Untersuchung ergab, dass das billigste Ausgangsmaterial die höchste Volumenausbeute und den höchsten Bruttogewinn ergab.
