岗位存在占有申请者条件下人岗双边匹配模型

Model for applicants/positions two-sided matching with occupied-applicants in positions

针对企业招聘中部分岗位存在占有申请者的人员与岗位双边匹配问题进行研究.首先,针对岗位存在占有申请者的人岗一对多双边匹配问题进行描述;然后,分别给出岗位存在占有申请者的人岗双边匹配方案、岗位存在占有申请者的个体理性匹配方案、占有申请者与岗位阻塞对、外部申请者与岗位阻塞对和岗位存在占有申请者的稳定匹配方案的定义,进一步依据企业招聘过程中申请者与岗位提供的对对方的评价信息,分别计算人员与岗位的满意度,在稳定性约束的基础上,构建以人员与岗位的满意度最大、占有申请者回到原岗位的人数最少为目标的多目标优化模型,通过改进的和声搜索算法求解模型,获得稳定匹配结果;最后,通过算例表明所提出方法的可行性和有效性.

The problem of applicants/positions two-sided matching with occupied-applicants in positions is studied.Firstly,we describe the problem of the applicants/positions two-sided matching scheme with occupied-applicants in positions.Then,we give the definitions of the applicants/positions two-sided matching scheme with occupied-applicants in positions,the individual rationality matching scheme with occupied-applicants in positions,blocking pair of occupiedapplicant and post,blocking pair of external-applicant and post,and the stable matching scheme with occupied-applicants in positions,respectively.Furthermore,the satisfaction degrees of applicants and positions are calculated based on the supply and demand information provided by applicants and positions,respectively.Based on constraint of stability,a multi-objective optimization model for maximizing applicants’and positions’satisfaction degrees and minimizing the matching numbers between occupied-applicants and their initial occupied-positions is constructed.By solving the constructed model,an improved Harmony search algorithm is designed,and a corresponding stable matching alternative is determined.Finally,a numerical example is given to illustrate the feasibility and effectiveness of the proposed method.
