|Title:||Storage Logistics Of Fruits And Vegetables: Effect Of Temperature|
|Author:||De Freitas Borghi D.|
|Abstract:||The main objective of this study is to minimize the losses of fruits and vegetables that happen during its storage, using mathematical models to optimize the products distribution in deposit and to minimize costs referring to the storage of these products. The mathematical model for optimization used a mixed integer linear programming (MILP) formulation. It was implemented in the software GAMS® and the solver used was CPLEX®. Simulations were conducted considering various temperatures of storage and the same cost of U$ 1.00 for every analyzed product, aiming to minimize the costs relating to its storage. Starting from values of keeping quality of the products and considering two storage zones (refrigerating chamber and external deposit) it was possible to proceed an analysis in relation to keeping quality of each product in function of the temperature. The results showed that the more distant the real storage temperature of a product is of its ideal temperature, the greater the costs with the loss of quality of this product. It was verified that the cost relating to the loss of quality of products has great influence on the total storage cost. It shows the importance of optimizing the storage logistics of these products, so that these costs are not still more expressive, what certainly occur without a tool for that. It was also verified the order of products priority to occupy the chamber. The results showed that it depends on the temperature, but fruits as grape and plum have larger priority in majority combinations of temperatures, followed by peach and strawberry. Papaya, bell pepper, tomato and cucumber have great variation in its priority and for smaller chamber temperatures (Tc), the products with smaller priorities were cucumber and tomato, but for larger Tc were cauliflower and celery. In that way, the proposed model comes as a tool that can help distribution centers managers in taking decisions referring to the logistics of storage of fruits and vegetables in order to minimize total costs and losses of the sector.
