- 研究成果概要
- One of the main challenges for the manufacturing industry is to ensure the appropriate allocation of
benefits to all subsidiaries to achieve the ideal pattern of rapid and shared
growth. Transfer price, which is the internal price among subsidiaries of a
global manufacturing firm, is an important financial and business issue.
However, most previous studies simply assume transfer prices. Our study reveals
that transfer pricing can lead to different total profits of global supply chains
and different profit allocation effects on subsidiaries. Furthermore, the exchange
rate is also considered with production planning since it is treated as an
important global factor that can cause the profits of all subsidiaries to
fluctuate. We add exchange constraints on both manufacturing and sales
subsidiaries to reduce the inappropriate allocation of profits among
subsidiaries. A profit allocation approach is proposed that considers transfer
pricing and exchange rate simultaneously with production planning. The model is
formulated using nonlinear programming with a nonconvex objective function and
nonlinear constraints. However, we overcome modeling challenges using piecewise
linear modeling and are able to obtain mixed-integer linear programming (MILP)
model, which can be solved using a linear programming solver. The result of this study was presented in 25th International Conference on Production Research (ICPR).
