Method and system for determining optimal ordering time of drug purchasing

Abstract

The invention relates to the field of medicine, and discloses a method and system for determining the optimal ordering time of medicine purchasing. The method comprises the following steps: calculating the saleable days of each drug according to historical sales data and current inventory; subtracting a preset purchasing period Tc and purchasing distribution time from the saleable days of each medicine to obtain a safe saleable day Ts of each medicine; taking various medicines of which Ts is less than Tc as a first kind of medicines, and taking the latest ordering time point as the optimal ordering time; taking various drugs with Tc < = Ts < 2Tc as a second class of drugs, and calculating the daily proportion of the purchase amount of each drug in the second class of drugs; summing the Tmday with the maximum daily proportion and the daily proportions of the previous days, and if the sum value is greater than a preset threshold, taking the latest ordering time point as the optimal ordering time of various medicines of which Ts is less than or equal to Tm in the second type of medicines.
