Studies on Spatio-temporal Collaboration Model for Location Analysis of Vegetable and Fruit Logistics

Time and space are two of the most essential elements of fresh agro-food logistics such as vegetable and fruit, in order to achieve the spatio-temporal collaboration in its logistics location analysis, this paper has analyzed the interior mechanism of vegetable & fruit logistics from the point of view of two dimensions, i.e. time and space, a traditional p-median model is revised by adding time dimension on distance-based spatial dimension and applied in analyzing the site selection of vegetable & fruit distribution center in Beijing. It is shown that the revised p-median model can effectively resolve the problems of site selection for perishable agro-food, which could make for the decision-making to ensure vegetable & fruit agro-food to enter Beijing market expediently and efficiently, and could also reduce the wastage and logistics costs.
