dc.description.abstractINTRODUCTION: WHEN SAWING LOGS WITHOUT DIAMETER SORTING, THE CUTTING PROGRAM GENERATES DECISIONS AND ROUTES DEPENDING ON THE LOG?S APPEARANCE AND MACHINE LOAD. OBJECTIVE: TO OPTIMIZE THE PRODUCTION FLOW OF A CUSTOM-CUT PINUS RADIATA D. DON SAWMILL, THROUGH DETECTION AND ANALYSIS OF CRITICAL MACHINES, USING DISCRETE EVENT SIMULATION AND EXPERIMENTAL DESIGN. MATERIALS AND METHODS: TWO SIMULATION MODELS WERE DEVELOPED FOR SAWING LOGS WITH LENGTHS OF 2.5 AND 5.0 M, AND DIAMETERS BETWEEN 34 AND 44 CM TO PRODUCE SAWNWOOD WITH A THICKNESS OF 5/4? WITH VARIABLE WIDTH. THE NUMBER OF LOGS PROCESSED PER SHIFT WAS THE RESPONSE VARIABLE OF THE MODEL. HEAVILY-USED MACHINES AND TRANSPORTS WITH LONG QUEUES WERE CANDIDATES FOR CRITICAL MACHINES. THE IMPACT ON PRODUCTION WAS DETERMINED BY MEANS OF EXPERIMENTAL DESIGN, WHERE THE FACTORS ASSESSED WERE: (A) DELIVERY FROM BANDSAW CARRIAGE 1 TO BAND SAW 3, (B) INCREASED DEBARKER CAPACITY, (C) FAILURES ELIMINATED FROM BANDSAW 1 AND 2, AND (D) DIRECT DELIVERY FROM BANDSAW 2 TO EDGER 2. RESULTS AND DISCUSSION: MODIFICATIONS TO THE PRODUCTION FLOW WERE PROPOSED BECAUSE FACTORS B, C AND D SIGNIFICANTLY INCREASED (P = 0.1) THE PRODUCTION LEVEL (LOGS PER SHIFT); THE INCREASES OVER THE SAWMILL?S INITIAL CONDITION WERE 13 AND 18 % FOR LENGTHS OF 2.5 AND 5.0 M, RESPECTIVELY. CONCLUSION: SIMULATION AND EXPERIMENTAL DESIGN CAN BE APPLIED IN SMALL AND MEDIUM-SIZED SAWMILLS TO IMPROVE PRODUCTION WHEN PROCESSING LOGS WITHOUT DIAMETER SORTING.
