Full textThe main objective of this thesis is to investigate the production planning problem in the context of uncertain demand, variable service level, and uncontrollable supply in a wood remanufacturing mill. Production planning and control activities are complex and represent difficult tasks for wood remanufacturers. The complexity comes from inherent characteristics of the industry such as divergent co-production, alternative processes, make-to-order, short customer lead times, variable setup time, and uncontrollable supply. The first part of this thesis proposes an optimization/simulation platform to make decisions about the selection of a production planning policy to deal swiftly with uncertain demands, under the complex characteristics of the wood remanufacturing industry. For this purpose, a periodic re-planning strategy based on a rolling horizon was used and validated through a simulation model using real data from an industrial partner. The computational results highlighted the significance of using the re-planning model as a practical tool for production planning under unstable demands. In the second part, a dynamic safety stock method was proposed to better manage service level, which was threatened by issues related to limited production capacity and the complexity of setup time. We developed a two-phase periodic re-planning approach whereby idle capacities were allocated to produce more important products thus increasing the realization of safety stock level. Numerical results indicated that the solution of the two-phase method was superior to the initial method in terms of backorder level as well as inventory level. Finally, we studied the impact of uncontrollable supply on demand-driven wood remanufacturing production planning through an optimization and simulation framework. Different supply scenarios were used to identify the safety threshold of supply changes. The proposed framework provided managers with a novel advanced planning approach that allowed understanding the impact of supply policies to deal with uncertainties. In general, the wood products industry offers a rich environment for dealing with uncertainties for which the literature fails to provide efficient solutions. Regarding the results that were obtained through the case studies, we believe that approaches proposed in this thesis can be considered as novel and practical tools for wood remanufacturing production planning.

Full textIn recent years, the lack of wood supply predictability has been identified as a factor hindering the competitiveness of the forest sector. While several entities believe that the change in Quebec's forest regime in 2013 is one of the factors that led to this, it seems that the growing presence of a supplier-client relationship in wood procurement is also partially responsible. The problem of the lack of predictability is composed of two elements. First, no recognized definition of wood supply predictability has been proposed by the scientific community. Second, in practice, stakeholders do not seem to share a common understanding of what is wood supply predictability. In the absence of knowledge of the real causes of lack of predictability, it is difficult to come up with recommendations. To date, no study have addressed the issue of the lack of predictability of forest supplies. This work aims to fill this gap. A series of 20 interviews involving stakeholders of the forest supply chain was conducted. In addition, a case study of a Quebec pulp and paper mill examined wood supply predictability as part of procurement practices at the operational level. An evaluation methodology based on the data collection process in place, the contract allocation policy and the buyer forecasting methods have been applied. Based on our results, we define wood supply predictability as the ability to anticipate wood supply over time, within a certain degree of precision. 37 causes and 17 sources of the lack of wood supply predictability were identified through the interviews and the case study. These elements have been grouped into five categories. Finally, five causes specific to the management of suppliers and the monitoring of contractual agreements form the basis of recommendations aimed at improving predictability in the context of wood procurement. Four of the proposed recommendations favor contract allocation based on past performance of suppliers. A recommendation regarding quality monitoring of forecasts is also proposed.

Full textSupply planning is a significant challenge for the forest industry, particularly in natural forests characterized by great heterogeneity. Such forests produce raw material suitable for different final products. Thus, developing plans to match supply with demand becomes a complex problem for forest planners. The automatization of the planning approach using an optimization tool allows many important factors to be taken into consideration during planning. In the literature, several theoretical models have been proposed, but it appears that very few of these are currently used by companies. It is assumed that the complexity of the problem, the ever changing nature of the planning environment, and the expertise required to use these models limit their application in industrial context. Nevertheless, the implementation of such tools could bring significant improvements in profits for the forest companies. The aims of the study are threefold : (i) to evaluate the potential for the implementation of mathematical optimization in companies, in particular by identifying the additional resources needed to adopt such an approach, (ii) to estimate the potential gains associated with utilization of optimization model in formulating wood procurement planning in an industrial case, and (iii) to analyze the effect of variation in the information used could have on the plans. An optimization software (LogiLab) developed by the FORAC research consortium was used. The tool allows to maximize the profit generated on the entire supply chain through optimal allocation of raw materials to mills in the network. The model simultaneously considers both harvesting and transportation cost, the heterogeneity of the forest and mill performances. The planning done now in companies visually focuses on lower transportation distance. We adapted LogiLab to a case study involving a Canadian forest products company, to analyze the generated profits, and assess its potential for implementation. To realize the second objective, we studied the planning method of our Partner Company and compared it to the optimization approach that we used for generating the optimal plan. Finally, we adjusted the baseline inventory data using actual data from the measurement to test the effect of the variability of the information used in developing the plans. A higher net profit was generated when using our planning approach in comparison to the plan prepared by the company. This difference is due, in part, to a more efficient allocation of raw materials to the mills. With regards to the second objective, we found several advantages such as a reduction in the time needed to produce a plan. Moreover, even if the cost of implementation is high they are recovered in less than two years by savings in planning time. The gains generated following the optimized plans exceed by several orders of magnitude the initial costs of the system to be set up.
