摘要

Biorefining is now recognized as a promising solution to transform the struggling forestry industry and to generate value-added pathways. The implementation of new products and processes will help companies to diversify revenues, but implies several strategic changes in the business model. Companies will face the dilemma of exiting or not traditional pulp and paper operations, while selecting their biorefinery product and process portfolio. As well, they will have to enter new markets and manage production to minimize the risk of market volatility.;Over the past decades, both industry and academia paid a lot of attention to supply-chain management in order to increase the cost effectiveness of overall operations. The application of supply-chain management concepts could therefore greatly help the transforming North American forestry industry to compete globally.;The objective of this Ph.D. project was to propose and illustrate an integrated supply-chain planning framework for the management and the evaluation of forest biorefinery strategies. This framework, named margins-based , integrates principles from revenue management, activity-based cost accounting, and manufacturing flexibility in a tactical planning model that maximizes profit of a company.;The structure of the mathematical model and its associated cost model aims to represent as closely as possible the activities of a company, from procurement to sales. It enables the modeling of different process configurations leading to manufacturing flexibility. The model can thus be used as a platform for evaluating various operating strategies of a company, at both production and supply-chain levels.;A case study of a newsprint mill implementing a parallel biomass fractionation line producing several bioproducts was used to illustrate this margins-based approach. Various strategic and tactical analyses were conducted to show the relevance of the approach as a decision-making tool for management problems related to the forest biorefinery.;The model was used to evaluate the profitability of a company during its transformation to the biorefinery, by considering the gradual divestment in pulp and paper activities, while implementing a new biorefinery process. Results show that the tool can enhance decision-making activities by providing a better visualization and better comprehension of supply-chain and cost-related dynamics under different scenarios. Coupled with a scenario analysis, it offers the opportunity to develop a phased implementation strategy that would stabilize profitability during the transformation to the biorefinery.;The planning tool was also used to study the management of a product portfolio to mitigate the risk of market volatility. One analysis focused on the exploitation of thermomechanical and deinked pulping flexibility in order to minimize the cost of raw material procurement in different to market conditions. Another analysis examined the impact of feedstock and production flexibility of a fractionation process on sales and profitability.;Results show that the procurement and production needed to manufacture the product mix that provides the optimum margins vary significantly. Biorefinery processes can have complex interrelations that make dynamics and trade-offs between manufacturing options not easy to identify and understand. Results thus highlight the relevance of using such planning tools to identify the best opportunities. In a context where sales can be varied to a certain level, results also show that it may be beneficial to pay more for certain types of biomass if they offer a product portfolio mix with higher revenues.
