摘要
建立物流系统功能要素间成本投入数理模型,重点研究物流效益协同产生的机理,找出物流功能要素间成本投入满足效益背反与效益协同的条件和分界线,并通过算例分析对理论模型进行了验证。研究发现,当模型最优解为内点解、物流系统功能要素间质量替代弹性足够小且产品价格质量弹性足够大时,物流系统功能要素间成本投入满足效益协同。其他情况下,则满足效益背反。对鲜切花物流系统的案例研究表明,其功能要素间成本投入存在效益协同,与理论预测一致,并依此提出了完善其物流系统的相关建议。
This paper builds a theoretical model to clarify the relationship among costs input to functional elements of logistics system,studies the mechanism of collaboration relationship,finds out the condition of and boundary between trade off and collaboration effects,and verifies the theory by conducting a numerical example.The results show that it is of collaboration relationship among costs input tofunctional elements in logistics system when,firstly,the optimal solution of the model is the internal point solution,secondly,the qualitysubstitution elasticity of the functional elements of the logistics system is small enough,and thirdly,the price of the product is sufficient-ly elastic to quality.Otherwise,it is of trade-off relationship.The case study on cut flower logistics system shows that there is a collabora-tive relationship among costs input to functional elements,which is consistent with the theoretical predictions.At the end,some sugges-tions are given for improving cut flower logistics system.
