考虑性别偏好影响的通勤合乘匹配模型

Commuting Ride-sharing Matching Model with Gender Preference

为了增强通勤合乘的安全性,并提高合乘的匹配率,建立了考虑性别偏好影响的通勤合乘匹配模型.通过引入合乘匹配控制系数,新模型不仅可以分别处理了同性合乘、异性合乘、特别组合三种性别合乘模式,也可以分析以一种模式为主导,三种模式并存的情况.模型最优解可通过依次确定可行匹配集、计算各匹配相关特征量和利用分层法确定最佳合乘匹配来确定.数值分析表明:某种性别比例占优条件下,同性合乘模式的匹配效果较好,而异性合乘模式的匹配效果较差;当乘客均偏好与某一性别合乘时,该性别乘客如果占优,则匹配效果最好;随着性别偏好影响的逐渐减弱,通勤系统的合乘匹配效果逐渐提升.

To improve the safety of commuting ride-sharing and increase the matching rate of ride-sharing, a commuting ride-sharing matching modelconsidering the influence of gender preference was established. By introducing the matching control coefficient, the new model can not only deal with the same-sex ridesharing, the opposite-sex ridesharing and the special combination, but also analyze the coexistence of three modes dominated by one mode. The optimal solution of the new model can be obtained by determining the set of feasible matching pairs, calculating the relevant feature quantity of each matching and searching the optimal matching pairs with the hierarchy method. The numerical analysis shows that the matching effect of the same-sex ridesharing pattern is better than that of the opposite-sex ridesharing pattern under the condition that a certain sex ratio is dominant.When passengers all prefer to ride with a certain sex, the matching effect is best if the passenger of that sex is dominant. With the gradual weakening of the influence of gender preference, the ridesharing matching effect of the commuter system has gradually improved.
