This paper includes the answer of professor Pentti Hakkila for professor Mikko Kantola who in this issue of Silva Fennica gives some critical points on professor Hakkila’s earlier article (Silva Fennica vol. 9, no. 4 in 1975) on the status and future prospects of forest work science in the Finnish Forest Research Institute. He emphasises that the worry about the forest work reseach presented in his earlier article was not directed towards the research work but towards the financing of forest work science in Finland.

This article is a comment on a previous article in Silva Fennica (vol. 9, no.4) published in 1975, written by professor Pentti Hakkila, titled ‘The status and future prospects of forest work science at the Finnish Forest Research Institute’. It aims at giving some further aspects on the choice of research fields and subjects, and the concepts of result, opinion and research work.

The article reviews the position of the Department of Forest Technology in Finnish Forest Research Institute, among Finnish establishments in research on forest work. In addition, it describes the current research programmes of the departments both in wood harvesting studies and studies on silvicultural work. The equitable aims of the former are to increase productivity, lower the cost level, ease the work and improve job satisfaction, as well as to improve the utilization of wood raw material. The latter aims at e.g. improvement of the biological results.

Future prospects are surveyed from the point of view of the goals imposed by the State on the research and, on other hand, the appropriations earmarked for forest work science. A regrettable conflict has arisen between them.

The PDF includes a summary in English.

This article is a review of Finnish forest research in the field of forest technology in the previous 50 years. The field of research is relatively new among the forest sciences. In the beginning and still during the last century forest technology as an individual field of science was directed entirely towards the anatomical properties of wood and their uses, and to the chemical composition of wood. Later the attention was given to the actual forest work, mainly felling, logging and transportation of timber. The invention of production of wood pulp and cellulose opened new fields of work within the processing and use of wood.

The review indicates that the forest technological research is finally going ahead at full speed. It has proved right that logging technics have received attention in research. The technical questions are by nature such that they require a rapid solution in order that the production machinery would not stop.

The article is published in Finnish in separate PDF Acta Forestalia Fennica vol 70 no 7.

The article gives a summary of the range of the wood-technological research, and suggests that the research in the subject in Finland should be divided in two parts: research on problems of wood-technology in the strict sense of the word, and those concerning wood refinement and the problems of wood technology, related to the latter. The wood-technology research would be addressed to the Forest Research Institute, and the research on wood refinement to the organization to be founded by the wood manufacturing industry. Finally, main subjects to be studied are listed.

The volume 34 of Acta Forestalia Fennica is a jubileum publication of professor Aimo Kaarlo Cajander. The PDF includes a summary in English.

The article is a review of forest research carried out in Finland. The article includes a short review of the origins of forest research in the country and the research institutions in the country. It describes the main studies in different fields of forest research, divided on biological and silvicultural research, forest mensuration and forest policy research, and research on forest utilization.  English translation of the article was published at the same time with an Finnish article. A need for an English summary of the forest research was realized, because the publications have mainly been written in Finnish or German.

Technological development gives forest companies opportunities to maintain competitiveness in the highly cost-sensitive market for forest products. However, no previous studies have examined the technological development decisions made by forest companies or the support tools used when making them. We therefore aimed to describe and analyze 1) the processes used when making such decisions, 2) the associated decision situations, and 3) the use of and need for decision support tools in these processes, with a harwarder concept as case. Semi-structured interviews were conducted with respondents from six forestry organizations. Two theoretical frameworks were used to analyze the interviews, one for unstructured decision processes and one for decision situations. The respondents’ descriptions of their decision processes were consistent with those observed in other industries, and it was shown that decision-making could potentially be improved by investing more resources into diagnosing the problem at hand. The main objective in decision-making was to maximize economic criteria while satisfying threshold requirements relating to criteria such as operator well-being, soil rutting, and wood value. When facing large uncertainties, interviewees preferred to gather data through operational trials and/or scientific studies. If confronted with large uncertainties that could not be reduced, they proceeded with development only if the potential gains exceeded the estimated uncertainties, and implemented innovations in a stepwise manner. These results indicate a need for greater use of existing decision-support tools such as problem-structuring methods to enable more precise diagnoses, simulations to better understand new innovations, and optimization to better evaluate their theoretical large-scale potential.
