"It is not easy to tackle the many large scale and multidimensional problems of our world. It is necessary to explicitly recognize and handle dynamic development, risk, uncertainty, and applications in the best possible way while focusing on the relevant long term objectives. In my opinion, IIASA has been the most prominent institute in the world for international cooperation in this area.
I came to IIASA in 1985 as a participant of the Young Scientists Summer Program (YSSP) in the Systems and Decision Sciences (SDS) Program. Academician Professor Alexander B. Kurzhaski was the program director then as well as the deputy director of IIASA. Prof. Kurzhanski gave a very inspiring series of lectures on mathematical systems theory, and Prof. Jitka Dupacova gave important lectures on stochasic optimization and applications. Dr. Gaivoronski contributed with new findings in the field of stochastic problems. I was very grateful for the opportunity to present my own work during the SDS seminar series during my YSSP in the summer of 1985. My two papers where then also published at IIASA:
Lohmander, P., Continuous extraction under risk, IIASA, International Institute for Applied Systems Analysis, Systems and Decisions Sciences, WP-86-16, March 1986
Lohmander, P., Pulse extraction under risk and a numerical forestry application, IIASA, International Institute for Applied Systems Analysis, Systems and Decisions Sciences, WP-87-49, June 1987
Later these papers were marginally adjusted and published as articles in a journal IIASA recommended:
Lohmander, P., Continuous extraction under risk, SYSTEMS ANALYSIS - MODELLING - SIMULATION, Vol. 5, No. 2, 131-151, 1988
Lohmander, P., Pulse extraction under risk and a numerical forestry application, SYSTEMS ANALYSIS -MODELLING - SIMULATION, Vol. 5, No. 4, 339-354, 1988
These papers were extended with more results and applications, and the latest versions of the two studies are found in my PhD thesis:
Lohmander, P., The economics of forest management under risk, Swedish University of Agricultural Sciences, Dept. of Forest Economics, Report 79, 1987 (Doctoral dissertation), 311p
Now, in 2018, our planet still faces dynamic and stochastic decision problems of many kinds. The management of our global natural resources, the energy sector, and international trade are a few examples. International cooperation is more important than ever before, in both research and in industrial development.
I hope that my suggestions in the following articles can give some inspiration and become useful tools in the management of present and future decisions.
