This paper mainly studies the distribution center location of FMCG agricultural products. It assumes that the decayed rate of perishable products is linearly changing, and builds FMCG agricultural products distribution center location model of the lowest total cost. Filter the optimal distribution center using the combination of qualitative and quantitative analysis, with approximation algorith...

obtaining temperature distribution data of slabs under rolling is essential as the mechanical and metallurgical properties of the metal under this process vary with temperature. using the control volume method, a mathematical model is employed in this study to predict slab temperature in the hot roll process at mobarakeh steel company. the effects of different parameters including the heat resu...
