Question

Goldratt suggests that a production system should be controlled using these three mechanisms.

Short answer

According to Goldratt, a production system should be regulated by the following three mechanisms. They are as follows:

1. Drum

2. Buffer

3. Rope

Step-by-step solution

Introduction

Goods are manufactured in the production system in response to consumer demands. These items are manufactured on a modest scale. The flow of output is irregular. In other words, the production flows are not constant. A wide range of items is manufactured in this sort of manufacturing system.

Analyze

Goldratt has suggested that a system of production must be regulated by drum, buffer, and rope.

Drum-Buffer-Rope (DBR) is a production planning application of the theory of constraints. DBR enhances the flow of processes with internal constraints or capacity-restrained resources, making them more efficient.

DBR specifies a work schedule for the constraint (Drum) and buffers it, so it is never starved (Buffer). It establishes a release mechanism (Rope) to guarantee that work is released into the system at the appropriate moment.
