|Abstract:||Bioenergy plants are expected to play an important role in green energy production from forestry biomass. To incorporate bioenergy plant in the forest supply chain, the industry requires new investments as well as new value chain design and management. On the other side, the uncertainties associated with demand and price of new products in the market may add risks to such large investment in current forest supply chain. Hence, the main objective of this thesis is to analyze and to propose new design of the forest bioenergy network in both a deterministic and a stochastic context. The first part of the thesis has proposed four optimization models for strategic, tactical and operational planning levels of the supply chain. The models have included several collaborative actions between all involved stakeholders of the supply chain. They have been integrated in a new educational tool called hierarchical transportation game. In the second part of the thesis, we have integrated the developed optimization models to propose an integrated value chain design and value chain management optimization model. This model has been used to analyze a forest bioenergy network in Newfoundland. Newfoundland forest supply chain comprising four major stakeholders was considered as our case study. The profitability of adding a new bioenergy plant as well as new terminals in several potential locations have been evaluated. Finally, in a third part of the thesis we have proposed the bioenergy network taking into account uncertainty on demand and price of all final products of a new value chain. Several potential bioprocesses with different technologies have been evaluated for our case study. To provide a risk-averse solution, we have proposed two risk management models. The results from the three parts of the thesis have demonstrated the impact of integrated planning, bioenergy plants and collaboration on improvement of forest value chain. In general, the work in this thesis can support an efficient transformation of the forest supply chain considering investment risks. The optimization models and approaches proposed in this thesis are novel and practical for the forest bioenergy network design problem.|
