Abstract

Buffer clustering policy for sequential production lines with deterministic processing times

Highlights

  • A sequential production line is defined as a set of sequential operations within a factory or distribution center whereby entities undergo one or more processes to produce a final product

  • The authors proposed transitioning the grouped buffers in the center of the work cell to a single buffer cluster shown in Fig. 3 which enables increased buffer utilization and reduces the size of the grouped buffers, reducing the buffer storage space

  • The manufacturing center desired to leverage the cluster for work cells to minimize the buffer storage space

Summary

Introduction

A sequential production line is defined as a set of sequential operations within a factory or distribution center whereby entities undergo one or more processes to produce a final product. A case study of a manufacturing facility (details found in section 4) desired to transition from a serial line configuration (Fig. 1) to a In this scenario, because the buffers were sized separately (i.e. dedicated buffers) with respect to the serial line and grouped in the center of the work cell, the grouped buffers were not leveraging available space in the neighboring buffers during the production shift. The authors proposed transitioning the grouped buffers in the center of the work cell to a single buffer cluster shown in Fig. 3 which enables increased buffer utilization and reduces the size of the grouped buffers, reducing the buffer storage space This allows the facility to benefit from efficiencies (e.g., increased throughput, work in progress reduction) by use of alternate configurations.
