The focus is to highlight literature on Drum-Buffer-Rope (DBR) scheduling and execution and control of that schedule through Buffer Management.

Today, TOC experts believe that Buffer Management is a necessary condition for an effective Drum-Buffer-Rope system. This scheduling and control mechanism has been extended across supply chains to pull inventory to consumers.

This extension of TOC into supply chains is known as Rapid Replenishment.

The purposes of this chapter are:

  • First, the precursors to TOC scheduling are described.
  • Second, a review and critique of the literature on DBR scheduling is presented.
  • Third, special cases such as free goods (when the market is the constraint), re-entrant flows, and remanufacturing are discussed.
  • Fourth, a review and critique of the literature on Buffer Management are presented.
  • Fifth, the literature on TOC replenishment is reviewed and critiqued.
  • Sixth, some suggested problems within DBR as presented in the academic literature are discussed.
