Multi-agent Game Simulation Research In Light Rare-earth Market

Rare-earth resource is an important strategic material, plays a role in aerospace military field.In order to improve the rare earth plants’ the level of profit, in resent years, scholars raise the modelof product mix have solved the questions of the difficulty in jointing cost of production, the modelof appropriate backlog have analysis the balance the opportunity cost of best-selling joint productsorder with the holding costs of lost with slow-moving joint product, the purity model haveconsiderate economic purity and resource utilization effect. But because the characteristics of jointrare-earth production product nested, the joint products’ price, yield, demand, influenced each other;the three models above required market information can’t get. Aiming at the light production rareearth market in Baotou area, we research between plants’ game and every plant’s internal operationoptimization to improve the precision of decision-making.The research of test in multi-agent with Game theory increasingly, the application of multi-agent research in the electricity market, steel market and the system simulation of operationalproduction has a prominent effect. These documents have established a swarm situational platformto simulate test, which achieved gratifying successes. This text learns for this method, applying toresearch of multi-agent simulation in the Rare-earth market.This text make use java language to program swarm and design simulation model of multi-agent competition in light Rare-earth. In view of the characteristic of joint production,4types ofRare-earth products for each other are affected, mutual suppression. This text has discussed severalof situations, considering the matching degree of demand share and material point (using Ginicoefficient measured), trade capacity surplus coefficient, cost level difference amplitude within eachenterprise and each product’s configuration mode between the business enterprises. The textanalyzes the different circumstances, what kind of measures to improve the profit of enterprise,provides the basis for decision-making of an enterprise.This text discusses a question that make “outsourced” to be an important factor in consideringtalking out the profits contrast, which there is a situation or not. It analyses the result of two cases. Incase there is work outsourced, plants can leverage the management of outsourced, which outsourceinferior products to other plants to increase profits, reduce the risk at decision, achieve maximumprofit.
