Supply Chain Optimization in Pulp Distribution using a Rolling Horizon Solution Approach
(Discussion paper2006:17, Working paper, 2006)
In this paper we consider a combined supply chain and ship routing problem for a large pulp producer in Scandinavia. The problem concerns the distribution of pulp to customers, with route scheduling of ships as a central ...
Continuous harvesting costs in sole-owner fisheries with increasing marginal returns
(Discussion paper2009:6, Working paper, 2009-09)
We develop a bioeconomic model to analyze a sole-owner fishery with fixed costs as well as a continuous cost function for the generalized Cobb-Douglas production function with increasing marginal returns to effort level. ...

Global warming and international fishery management : does anticipation of the temperature change matter?
(Discussion paper2010:19, Working paper, 2010-12)
This paper investigates the effects of climate-induced rising of ocean temperature on the optimal fishing policies in a two players’ non-cooperative game setting. We compare reactive management, under which the manager ...
Approximating closed form solutions to a class of feedback policies
(Discussion paper2009:8, Working paper, 2009-09)
Dynamic optimization problems cover a large class of problems in theoretical and applied economics. A simple iterative algorithm with fast convergence is proposed. It is demonstrated that the algorithm in a few steps ...
Optimal fishing policy for two species in a three-species predator-prey model: The case of capelin, cod and juvenile herring in the Barents Sea
(Discussion paper2007:29, Working paper, 2007-12)
This paper presents a management model for the Barents Sea capelin and cod fisheries including juvenile herring in the biological model as the young herring influences the cod-capelin system. The objective of the study is ...
RuttOpt : a decision support system for routing of logging trucks
(Discussion paper2007:16, Working paper, 2007)
We describe the decision support system RuttOpt, which is developed for scheduling logging trucks in the Swedish forest industry. The system is made up of a number of modules. One module is the Swedish road database NVDB ...
Supply chain planning of harvest operations and transportation after the storm Gudrun
(Discussion paper2006:16, Working paper, 2006)
The storm Gudrun hit southern Sweden in January 2005 and approximately 70 million cubic meters of forest was wind felled. The existing logistic planning at forest companies in the damaged area had to be changed over night. ...
Cost allocation in collaborative forest transportation
(Discussion paper2006:15, Working paper, 2006)
Transportation planning is an important part of the wood flow chain in forestry. There are often several forest companies operating in the same region and co-ordination between two or more companies is rare. However, there ...
