COURSE DESCRIPTION and OBJECTIVES
Stock-flow analysis of feedback systems presented for policy analysis and management. System dynamics; principles of systems employed to structure the problem solving process. Problems and case studies solved using microcomputers.Upon successful completion of this course, the student should be able to:
1. Model, both mathematically and visually, concrete and abstract dynamic structures of a system environment.REQUIRED TEXTS AND MATERIALS2. Provide a foundation for the consequences of feedback, time delay, and non-linear activity in problem analysis and synthesis.
3. Develop and test the influence of endogenous and exogenous policy change variables upon environmental performance.
4. Provide cases where stock and flow analysis has provided unique insight into major issues.

COURSE REQUIREMENTS AND GRADING
1. Examination (25%): There will be an in-class, closed book mid-term examination to test the student’s understanding of the basic concepts discussed early in the course. Format includes multiple choice questinos, causal loop diagramming, analysis and creation of stock and flow diagrams.The course grade of "B" represents the benchmark. It indicates that the student has fulfilled all course requirements and demonstrated competency in the subject matter of the course. Only those students who fully meet this standard and who demonstrate exceptional comprehension of the course subject matter, merit an "A". Students who do not meet the benchmark standard of competency will earn the course grade of "C". In those cases where there is substantial failure, the student will earn an "F". Plus and Minus grades are awarded.2. Individual Project (30%): Each student will create a system dynamics model in an area of their choosing. The model should be the student’s own work. Students may wish to refer to past International System Dynamics Conference Proceedings on the System Dynamics Society Homepage or to Prior Student Projects to get a feel for model domains.
3. Group Project (25%): Students will be assigned to a small group to create and exercise a joint model. See the following detail project description. A joint grade will be assigned to all members of the group. Additionally a peer evaluation will be utilized to measure and evaluate group cooperation. Individual grades may be adjusted accordingly.
4. Homework (10%): Two homework assignments will be completed and submitted. The assignments will be graded to insure adequate progress in absorption of the material. Students should work alone on these assignments. Homework Assignment 1 Homework Assignment 2
5. Class Participation (10%): A great deal of the graduate learning experience is gained through a discussion of shared experiences and methods for improving quality and processes. In-class exercises and discussion will therefore be evaluated. The criteria (from most important to least important) for judging a student’s contribution to the discussions are quality (well thought out, relevant to the topic), clarity, and frequency.

Individual Project Papers and Models |
The individual project consists of a unique systems study, further manifested through a dynamic model created in ithink. Students should create an accompanying 3-5 page paper which provides a description of the variables, explains the context for the model and talks to discoveries made while exercising the model. At the eighth class period each student should submit a brief one page project description of the model they plan to build. An example follows below:
Units of Analysis: Dollars, Numeric Effectiveness Factor (Interval Scale)
Sectors to be included: U.S. Congress, USAID Senior Management, USAID Technology Management
Time Period: 20 years in 1 year intervals
Example Output Variables: Ratio of Effectiveness to Prior Year Funding; Empowerment Utility
To Study the Effects of: Delays and Effectivness in increasing/decreasing budget dollars allocated to information technology.
Final Deliverables
The final project will be presented to the class in Session 14. The final ithink model and written 3-5 page paper are due at that time. The student will demonstrate and discuss the model in class and provide each instructor and each classmate with a 1 page description (diagram printout also very helpful) of the model.
Students should refer to prior student models (available from the instructor)
to get a feel for the depth and complexity that is expected. A typical student
model would have about 4 - 12 stocks and 15 - 30 converters. Real world models
typically have hundreds to thousands of stocks and converters. These prior
student projects may provide some aid in understanding appropriate modeling
topics.
Examples:
Deliverables (due on evening of presentation - hardcopy and softcopy):
a) Model - completed model with minimum 10
activities/variables and 4 loops.
b) Paper -
minimum 5 page paper providing model foundations and conclusions.
c) Presentation - 20-30 minute in-class.
d) Handout - single page for all class members on
the substance of the model.
