The Theory of Constraints (TOC) body of knowledge has created solutions for many different business scenarios from manufacturing, to project management, to supply chain, to retail, to even new product design. The oldest tool was the Drum-Buffer-Rope (DBR). A simplified version of this was proposed By Eli Schragenheim which assumed the market to be the constraint and used only one buffer. This method is striking for its simplicity of application. One key point missing in the TOC literature is the size of the buffer and its impact on the throughput of the system. Also missing is the impact of the moderating impact of the splitting of the orders received on the relationship between the buffer size and the throughput. This paper proposes two hypotheses that connect buffer size and order split to the throughput.

摘要

The Theory of Constraints (TOC) body of knowledge has created solutions for many different business scenarios from manufacturing, to project management, to supply chain, to retail, to even new product design. The oldest tool was the Drum-Buffer-Rope (DBR). A simplified version of this was proposed By Eli Schragenheim which assumed the market to be the constraint and used only one buffer. This method is striking for its simplicity of application. One key point missing in the TOC literature is the size of the buffer and its impact on the throughput of the system. Also missing is the impact of the moderating impact of the splitting of the orders received on the relationship between the buffer size and the throughput. This paper proposes two hypotheses that connect buffer size and order split to the throughput.
