MODELO DE UN SISTEMA MULTI-AGENTE PARA LA OPTIMIZACIÓN DE LA CADENA DE SUMINISTROS EN LA INDUSTRIA DE LA MADERA DE CONÍFERAS MUTI-AGENT SYSTEM MODEL FOR THE OPTIMIZATION OF SOFTWOOD INDUSTRY SUPPLY CHAIN

The lumber industry sector forms a productive chain that be summarized in the three processes: sawing, drying and remanufacturing. Where satisfying the requested volume and meet the planned delivery dates is important to both, the client and each production chain. The non-integration presents coherence issues in the production plans. Hence, an integrated model in lumber sector, that uses the working advantages of multi-agents systems, works to improve coherence and the system’s global productivity. The integration model presented in this paper minimizes global tardiness of the lumber transformation chain, at the moment of delivering production orders. Within the system, the communication between agents is done by using the Contract Net Protocol. The results show the sawmill, as a first step in the system, is where the biggest tardiness and bottle neck in the fulfilling of the production orders is produced. In average, the results showed a tardiness between 2 to 4 days in the compliance of chain production orders. The maximum delay is of 20 days.
