摘要： 研究了电子中介在旧车交易市场中多个买家和多个卖家各交易一辆旧车的双边匹配问题·设成交价格为买方出价和卖方定价的中间值,以总成交额和交易总剩余分别最大为目标,建立了多目标模型,并用加权方法求解·用仿真试验比较了单独考虑总成交额目标及两个目标同时考虑时的中介收益与交易方剩余变化情况,得出了同时考虑两个目标比单独考虑总成交额一个目标更为合理的结论·计算表明:与单独考虑总成交额最大相比,该多目标模型及求解方法减少总成交额约12%,但提高交易剩余约88%;如果保持中介收益不变,则中介费用可从2%提高到2 27%·

Abstract: A bipartite matching problem of electronic brokerage is discussed in case each and every one of several buyers/sellers wants to buy/sell a second-hand vehicle. A multi-objective apportion model is therefore developed, of which the two objectives are to maximize the gross volume of trade and total trade surplus, supposing that the clearing price is just the mid-value of bid price and offering price. This multi-objective model is solved through weighted method. A simulation is made to compare broker's commission and change in trade surplus from two aspects: taking account of both the objectives simultaneously and one of them only, i.e., to maximize the gross volume of trade. A conclusion is reached through computation that taking account of the former is more gainful, i. e., the gross volume of trade will decrease by about 12%, while the total trade surplus will increase by about 88%. Moreover the brokerage rate will increase to 2.27% from 2% if broker's commission remains unchanged.
