Modelling and Analysis of Bargaining Process for E-Procurement of Large Enterprise Group

To solve the bargaining problems of centralized procurement in the environment of e-commerce, we propose a visible tool named as Bargaining Process Chart to support bargaining process. By mapping any bargaining process into a curve from the point with coordinates (0,1) to the halving line of the first quadrant in Cartesian coordinates, Bargaining Process Chart makes the current and historical bargaining processes become visible. Thus, the negotiators can obtain efficient support from the useful information in their price bargaining. The bargaining process chart had been applied to the e-procurement centre of a big enterprise group in China. The application results are satisfactory.
