This paper attempts to develop a dynamic alignment approach to leverage design of system dynamics models. The approach developed in this research is a flow-based design, different from traditional macro designs of aggregated system structures or loop analysis. It is grounded on some major concepts in Synchronous management at plants and uses the Drum-Buffer-Rope (DBR) system to align the various operations of rate decisions. This paper takes two famous system dynamics models as examples to examine the performance of the proposed leverage design method. One is the customer-producer-employment model, and the other is the market growth model. Both of the models are developed by Forrester(1961; 1968). By applying the dynamic alignment approach, the redesigned customer-producer-employment system shows that the original oscillation behavior can be fully eliminated, and the redesigned market growth model can sustain its growth pattern instead of stagnation or collapse. By comparison with previous high leverage design methods, the dynamic alignment approach developed in this paper is proved to be more efficient and robust for system redesign in different scenario.
