Abstract: This work was carried out with the objective to implement a computational model for simulating the dynamics of an industrial slaughtering for swine. Modeled real system belongs the Frimesa enterprise, located in Medianeira city, Paraná State, Brazil. Implemented model was classified as: dynamic, discrete and stochastic, and simulates thirty-four unity operations. For model implementation it was employed the simulation language EXTEND™. Model validation was carried out comparing data related to five operational shifts, when it was slaughtered 1,346, 1,630, 1,360, 1,585 and 1,550 pigs, respectively. As contrasting parameters between data gotten from real system and generated by model, it was selected the following variables: (i) spent operational time; (ii) spent time from stunning area to scrap machine, (iii) spent time from stunning area to cold storage chamber; (iv) number of re-inspected carcasses; and (v) final number of edible slaughtered swine. At model validation was evidenced that for spent operational time averages, according to Tukey's test, at the significance level of 1%, it was not detected statistical differences between real system and generated simulation model data. According to this and other analyses, lead to the conclusion that model and system outcomes were in good agreement. Furthering, two sensitivity were carried out. In the first it was modified the number of swine to be slaughtered from 1,000 to 2,000. It was observed that spent operational time increase from 6.20 to 10.20 h. At the second, it was simulated the slaughter of 1,340 pigs, and was varied processing rates from 300 to 600 pigs per hour, at this situation operational times decreased from 8.10 to 7.40 h, respectively. © 2006 SBCTA.
