Internal supply chain management in the Chilean sawmill industry

Purpose – The existing business paradigm in the sawmill industry is that improvements are achieved by enhancements at each individual sawmilling plant. The authors investigate a collaborative approach, and propose a model for optimizing production and inventory planning decisions within a system of plants. Design/methodology/approach – The methodology models the sawmill production process in terms of two transformation stages and two inventory stages. The authors then extend the model to account for supply chain decisions consisting of timber transfers among plants. They apply the model at 11 Chilean sawmills to evaluate whether they can benefit from operating in a more integrated manner. Findings – The authors find an opportunity to increase profits by more than 15 percent through a higher utilization of the capacity and a better assignment of production orders.
