Abstract: | The beer game has been used to emphasize, investigate, and analyze supply chain inefficiencies as well as the effect of decision makers’ biases. This paper investigates the short- and long-run performance in the beer distribution game by analyzing Sterman’s (Manag Sci 35(3): 321–339, 1989) model that simulates decision-making. In this model, the system may have chaotic behavior depending on the heuristics used by decision makers. We investigate how quickly the system reaches a steady state (if at all). It is known that ignoring supply line (outstanding orders) leads to the bullwhip effect in experimental research. Among other results, we show that the short-term performance of a supply chain is not a predictor of the long-term performance even when decision makers fully recognize outstanding orders. Results of the simulation and practical implications are discussed. |
