两级物流服务供应链任务分配模型

在不确定需求的情况下,研究了物流服务集成商(LSI)面对多个功能物流服务提供商(FLSP)时如何进行订单任务分配的问题.结合物流服务供应链(LSSC)订单任务分配的特点,给出了基于多种物流能力的任务分配模型,考虑了LSI成本最小化、FLSP满意度最大化和惩罚强度最小化、不同能力之间尽可能匹配等条件,并给出了模型的求解方法.利用LINGO8.0软件对任务分配模型进行算例分析,探讨了不确定程度和关系成本系数对任务分配结果的影响.研究结果表明:随着不确定程度的增大,LSI的总成本将增大,FLSP的总体满意度将降低,而总体的惩罚强度将增大;LSI关系成本系数对FLSP总体满意度和惩罚强度有紧密的关系,关系成本系数越大,FLSP的总体满意度越大,惩罚强度则越小.

An Order Allocation Model in Two-Echelon Logistics Service Supply Chain

How to execute the order allocation when logistics service integrator(LSI) faces to many functional logistics service providers(FLSP) under indeterminate customer demand environment was discussed.Based on the characteristics of order allocation in logistics service supply chain,the order allocation model with multiform logistics capacity was given.This model considers four goals including to minimize the cost of LSI,to maximize the satisfactory of FLSP,to minimize the penalty intensity from FLSP and to match different logistics capacity possibly.The model solution method was also proposed.A practical example was given by software LINGO 8.0 and the effects of demand uncertainty and relationship cost coefficient on order allocation were discussed.The results show that with the augment of uncertainty,the general cost of LSI is increasing,the total satisfactory of all FLSPs is decreasing while the general penalty intensity of all FLSPs is increasing.Meanwhile,the relationship coefficient is closely correlative with the satisfactory and general penalty intensity of FLSPs.The greater the relationship cost coefficientis,the more satisfactory and the less penalty intensity of FLSPs.
