Summary

This video is a lecture from MIT’s course on building serious system dynamics models. The session focuses on managing drug development pipeline. The instructor begins by reviewing the predator-prey model, highlighting its limitations due to lack of saturation effects. He then discusses the challenges in modeling the drug pipeline, including failure rates, growth, and stock adjustment. The core of the session is a review of student models, particularly Alban’s model, which uses a cascade method to calculate desired stocks backwards from desired revenue. The discussion covers the importance of incorporating success rates and equilibrium conditions. Alternative modeling approaches are also presented, such as Hassam’s multiple-trial model. The instructor emphasizes the need for proper stock adjustment and the use of first-order delays. The video provides practical insights into model formulation and critique.
