Optimization of the Production Planning in the Supply Chain (Market-Sawmill-Harvest) using a Game Theory Approach

This paper presents the study of one optimization of the production planning model in the supply chain wood Industry: market, sawmill and harvest, multiperiod and a planning horizon of two years, which means of maximizing the profitability of a mix of wood products, incorporating an approach of game theory. This approach would incorporate the decisions of corporate governance the trade-off of the value chain of products. To develop the integrated model, is studying the behavior of prices for timber products in the market place. It chooses a mix of products, whose market prices are simulated, incorporating location data of customers, purchase orders and quantities and qualities of products required. The mix of wood products chosen, must be assigned to different sawmills to be produced using a distribution model, based on the principles of game theory. Sawmills are characterized by production capacity, facilities location, technologies, cost, storage capacity, patterns and cutting, diameter and geographic location log. Once given the mix of products to sawmills, will develop a simulation model that allows generate patterns cuts for mix products. This model delivers the demand for logs for the forestry companies. The demand logs will be assigned to different sites harvest, which Proceedings of the 51st International Convention of Society of Wood Science and Technology November 10-12, 2008 Concepción, CHILE Paper WS-13 2 of 8 are characterized by quantity resource, price, availability and allocation forest, using a model with approach of game theory. It hopes to develop a model that considered the overall objectives of the business unit and not the individual players in the supply chain. Using principles of game theory, allow incorporated into the model, situations where players make choices in a context of interaction and a pre-defined framework, which allows comply with the strategic decisions of enterprises.
