   Sammanfattning : As a result of the increase in accessibility of computational resources and the increase in the power of the computers during the last two decades, designers are able to create computer models to simulate the behavior of a complex products. To address global competitiveness, companies are forced to optimize their designs and products. LÄS MER

5. 24. Application of operations research in operative planning in the forest industry

   Författare :Patrik Flisberg; Mikael Rönnqvist; Jens Clausen; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; operative planning; routing; forestry; modelling; Decision Support System; optimization; OR in practice; Optimization; systems theory; Optimeringslära; systemteori;

   Sammanfattning : The focus of this thesis is the use of Operations Research for pplications in the forest industry. Optimization models and methods have been developed for problems in the forest supply chain and they have been integrated in decision support systems. The problems considered in this thesis are operative with a planning horizon of less than a month. LÄS MER
