Supply Chain Dynamics Workshop

EDP: Supply Chain Dynamics

Supply Chain Dynamics Workshop

30-31 January 2015 – Vietnam
Facilitators: MISI Dr. Albert Tan & MISI Dr David Gligor
Organiser: CEL Consulting

Learning Outcome

  • Learn to map the feedback structure of a system using causal loop diagrams.
  • Learn to identify stocks and flows and understand the basic dynamics of stock.
  • Learn to formulate and specify system dynamics models using Vensim software.
  • Learn to perform supply chain simulation analysis and interpret results.

Objectives and Scope
This course introduces you to system dynamics modeling for the analysis of supply chain policy and strategy. You will learn to visualize a supply chain in terms of the structures and policies that create dynamics and regulate performance. System dynamics draws on feedback theory and techniques of mathematical modeling and computer simulation to elucidate the relationships between structure in systems and the patterns of dynamic behavior they exhibit over time. A common theme that runs through the course is the search for connections between the behavior of people (and groups) in organizations and the organizational trajectories they generate. How do interactions among physical, cognitive, social, and informational factors in various organizational settings lead to dynamic behavior over time?
System dynamics allows us to create models and management flight simulators where space and time can be compressed, slowed, and stopped so we can experience the long-term side effects of decisions, systematically explore new strategies, and develop our understanding of complex systems. We use role playing games, simulation models, case studies, and management flight simulators to develop principles of policy design for successful management of complex strategies. We will consider the use of systems thinking to promote effective supply chain decision making.
The principal purpose of modeling is to improve our understanding of the ways in which an organization’s performance is related to its internal structure and operating policies as well as their supply chain. During the course you will use several simulation models to explore such strategic issues as fluctuating sales, production and earnings; market growth and stagnation; the diffusion of new technologies; the use and reliability of forecasts; and the rationality of business decision making.
