內(nèi)容簡(jiǎn)介:
Theoretical studies of bullwhip effect (BWE) in supply chains have focused on models of a single firm making its ordering decisions based on its own demand history. On the other hand, in an industry that has several firms, a firm’s demand in a period may be influenced not only by its own demand history but also by that of the industry and empirical data suggest that. This paper examines BWE when a firm’s demand in a period is correlated with its own demand (auto correlation) and with the industry demand in the previous period (cross correlation). Our analysis shows that the sign and magnitude of the cross correlation affect BWE at both firm and industry levels. Furthermore, cross correlation may have opposite effects on BWE at these two levels, which may partly explain the mixed observations of BWE at firm and industry levels. Results from an extensive empirical study generally support the theoretical predictions of our model.
