Abstract

Chen, W.; Yang, Z., and Pan, W., 2015. Port strategic alliance partner selection using grey target model based on error propagation and vertical projection distance.

The port strategic alliance partner selection is a decision problem, this article introduces an approach to partner selection with grey target model. Currently, researches concerning with interval number grey target multi-attribute group decision making (MAGDM) still have low precision of attribute weight interval, unscientific determination of expert weight and unreasonable optimality sorting of decision targets. Focusing on above problems, a grey target MAGDM analysis method based on error propagation and vertical projection distance is proposed. In this method, we determine the attribute weight interval by using the error propagation model proceeding from the error angle of view of the interval number attribute value. Subsequently, we collect the decision making information provided by all group decision makers according to the off-target deviation degree theory. Moreover, we establish an optimization model of decision maker weight at the purposes of minimizing the vertical projection distance, and simultaneously provide the optimality sorting by calculating the vertical projection distance between each scheme and the ideal scheme. Finally an example of selecting port strategic alliance partner is used to verify the feasibility and validity of the method.
