In the eighth volume of the Studies in Business Administration series from the Graduate School of Business at the University of Chicago, professors of business administration and applied mathematics present recent discoveries and research on advanced simulations within the international business planning world. Through research presented on the effectiveness of international business operations and management simulation by gaming, University of Chicago professors Hans B. Thorelli and Robert L. Graves present details on the development of The International Operations Simulation. Featuring modular design and an extraordinary degree of flexibility, the uniquely developed simulation is one of the first applications of sophisticated game design in an effort to mange problems in overseas operations and cope with international competitors in domestic markets. Serving as guideposts for the use of The International Operations Simulation, as well as acting as a source of inspiration for other management simulation designers, this presentation of in-depth research will prove to be a useful resource to everyone from game designers to educators.
