Abstract:

Supply-demand matching which is to find a suitable supply and demand cooperation scheme is the key to optimize resource utilization and form long-term partnership. With respect to the problem of supply-demand matching dominated of multiple commodities by the broker, the suppliers’ satisfaction about transaction price, the demanders’ satisfaction about transaction price and preference ordinal, and the importance of enterprises in both two sides from the broker perspective are simultaneously considered. A multi-objective optimization model is established, in which the satisfaction degree of weighted supply and demand is taken as object function and the specific restrictions in transaction as constrains. According to the characteristics of the research problem, an improved adaptive genetic algorithm is designed to solve the matching model. By a numerical example of mines, coal demanders and sea port, the matching results can be obtained and the feasibility and practicality of the proposed method can be demonstrated. It provides the reference and guidance for customer relation management of the broker.
