Embodiment Construction

[0021] The technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0022] A method for determining the optimum storage capacity of grain provided by the invention, the steps of the method are:

[0023] Step 1: Statistical relevant data, and calculate the grain storage rate r based on the statistical data.

[0024] Step 2: Establish the optimal grain storage capacity s according to the grain storage ratio r.

[0025] The detailed process of the above steps is introduced as follows:

[0026] Step 1: Statistical relevant data, and calculate the grain storage rate r based on the statistical data. Such as figure 1 The flow chart shown, the specific calculation process is as follows:

[0027] Food supply consists of domestic food supply and food imports, therefore, total food supply = domestic food supply + food imports. The ratio of domestic grain supply to total grain supply is R g (0g j (0j g +R j =1. ...

Abstract

The invention relates to an optimal grain reserves determination method and device. The method comprises steps that firstly, statistics of related data is carried out, a grain storage rate r is calculated on the basis of the statistics data, the r satisfies a formula described as specifications, the a refers to unit economic loss during grain shortage, the c refers to unit cost of grain storage, the Pg refers to grain supply interruption occurrence probability, the Pj refers to grain import interruption occurrence probability, and the Rj refers to a ratio of import grain amount to main grain supply amount; an optimal grain reserves s is established according to the grain storage rate r, s=r*H, and the H refers to a grain yield. The method is advantaged in that an optimal grain reserves model is established on the condition that whether a country has grain storage systems or not is considered, scientific and objective calculation can be realized on the basis of the model, bases are provided for reasonably determining grain reserves of our country, effective national grain supply capacity prediction can be guaranteed, and national grain safety is guaranteed.

Description

technical field [0001] The invention relates to a method and a device for determining the optimal storage amount of grain. Especially in the case of comprehensively considering whether there is grain storage or no grain storage, to determine the optimal grain storage amount belongs to the technical field of grain security. Background technique [0002] Establishing and maintaining an appropriate scale of grain storage is an important means to achieve food security, and changes in the level of grain storage are an important indicator for measuring and evaluating food security. Once there is a serious shortage of supply in the grain market, it will cause huge fluctuations in grain prices, which will have a huge negative impact on the development of society and even the security of the entire country. Grain storage can not only ensure that people get the food they need, maintain social stability, but also play a role in regulating market supply and demand and maintaining food ...
