摘要：RF-POLCA has been proposed as an alternative to POLCA. This is a production control mechanism simpler to implement that uses authorization dates only at the first cell in the POLCA chain. Although POLCA has been extensively studied, the performance of RF-POLCA largely remains unknown. RF-POLCA is here studied and compared with POLCA, considering: POLCA chains dimension, processing times variability, and shop configuration. The study is carried out using discrete event simulation. Results for the divergent and convergent shops show that RF-POLCA performs better than POLCA for shorter chains, while performing worser for longer chains. In the flow shop, where there are few intersections between POLCA loops, RF-POLCA performs better than POLCA for both, short and longer chains.
