Impacto dos parâmetros de um sistema produtivo em suas medidas de performance: um estudo de simulação em uma job shop

Abstract

In the industrial eviroment there is a famous speech that says that short setups, batch(lot) size and order sequencing are fundamental to performance in the industrial context, with strategic implications. The objective of this paper is to evaluate the impact of the variation in parameters of manufacturing systems on their performance measures. These factors were investigated in an environment of computer simulation of discrete events in the Flexsim software in relation to different scenarios for a productive system composed of nine operations, collectively organized by job-shop and later analyzed in relation to assertives stated in the literature. The results indicated that there seems to be no linear relationship between the factors and that makespan is smaller when setup times are low and lots are unitary, regardless of the adopted sequencing; And larger when setup times are high and lots are great as well, as expected. to reduce the setup times before adopting small lot sizes and to invest in technology to optimize production sequencing.
