Abstract: This research evaluates the impact of some dispatching rules (DR) on the performance of make-to-availability (MTA) under the simplified drum-buffer-rope (S-DBR) system. S-DBR/MTA seeks to ensure the availability of finished products to meet demand, so production needs to replenish inventory quickly. The DR has an important influence on the replenishment speed, which dictates the performance of such systems. We evaluate four rules found in the literature (FIFO, AT, SPT, and SRPT), two of the S-DBR/MTA (PSP and PSP1), and six rules combining the two groups (PSP-AT, PSP-SPT, PSP - PSP1-AT, PSP1-SPT, and PSP1-SRPT) using a computational experiment. We use the following measures to evaluate the performance of such rules: service level, average inventory in the system, mean flow time, and stock rate per service level percentage. The PSP1-SPT rule gets better results than others, increasing the S-DBR/MTA performance. [Received: 17 August 2022; Accepted: 4 June 2023]
