Using GIS Technology to Evaluate Transportation of Ornamental Crops in Georgia

Journal of Agricultural Science and Technology(B) 2011年第1期1卷 8-19页

作者： J. Mantilla P. Thomas F. Stegelin J. Houston M. Chappel Department of Horticulture University of Georgia Athens GA 30602 USA Department of Agricultural and Applied Economics University of Georgia Athens GA 30602 USA

In the agricultural industry, the importance of transportation costs increases considerably as fuel and labor costs climb. Logistic cooperation is an important strategic alternative to reduce transportation costs and increase efficiencies. Georgia＇s ornamental industry is characterized by producers that share clients, routes and origins; however, each producer has an independent transportation system. This paper analyses a case study to determine if a transportation alliance, through a horizontal cooperation and routing junction among ornamental producers in Georgia, would reduce shipping costs, increase distribution efficiencies and reduce carbon dioxide emissions. Routing and cost analysis were conducted followed by a sensitivity analysis for each constraint. Results showed that with the use of the GIS ArcLogistics 9.3 software, transportation alliances in the ornamental industry are profitable in terms of transport efficiencies and internal and external costs. Total cost savings per shipping cycle ranged from 1.0% to 13.2%, miles driven savings ranged from 1.1% to 13.6%, total number of trucks required savings ranged from 2.5% to 10% and driving hours savings ranged from 1.0% to 18.4%. CO2 emission reductions were also achieved ranging from 1.2% to 8.4% per shipping cycle.

关键词： Transportation alliance horizontal cooperation routing junction ornamental shipping costs.

This paper addresses the multi-type products collaborative vehicle routing problem with time windows by ways of transshipment（CoVRPTWT）.This problem is mainly to solve the cooperation between small and medium-sized logistics *** the basis of meeting the requirements of customer service time and request,the logistics enterprises cooperate through transshipment to reduce the total cost.A mixed integer linear programming model with constraints of time and request is established to minimize the total *** is used to solve the ***,the computational results indicate that transshipment can efficiently reduce cost and the addition of time windows will increase the cost.

供应链突发事件风险不同于普通运营风险，属于低概率—高后果(LP-HC)型风险。根据供应链风险发生的来源，突发事件风险可以划分为三种类型：供应中断、运营中断和需求突变。文章讨论了企业间纵向协调和横向协作两种应急协作机制，并在三种不同类型的突发事件情况下，分别探讨了企业应急策略问题。通过对独立应急模式和企业间协作应急机制的对比和分析，提出了一种合理的供应链突发事件应急策略选择框架：对于供应或运营中断风险，企业横向协作应急策略更加有效；对于需求突变风险，企业纵向协调应急策略更加有效。

关键词：供应链风险突发事件协作应急横向协作纵向协调 supply chain risks supply chain disruptions emergency cooperation vertical cooperation horizontal cooperation
