Embodiment 1

[0056] Embodiment 1 The method for splitting accurately in proportion comprises:

[0057] 1. Multiply the total amount and the ratio to get the ideal value of the item (with decimals)

[0058] 2. Split the ideal value into an integer part and a decimal part.

[0059] 3. Execute the loop to determine whether the sum of the current fractional parts is greater than 0.5. If the sum is greater than 0.5, the largest number in the current fractional part is -1, and the corresponding integer part is +1.

[0060] 4. When the sum of the decimal parts is less than 0.5, that is, after the loop ends, the integer part is the actual value we want to calculate.

[0061] For example: there are currently 9783 coins that need to be distributed to three people, and the proportions that these three people need to hold are 25.3%, 38.2%, and 36.5% respectively.

[0062] First, according to the first step, calculate the number of coins each person gets: 2475.099, 3737.106, 3570.795.

Embodiment 2

[0069] Embodiment 2 The method of multi-dimensional accurate splitting in proportion

[0070] Multi-dimensionality refers to splitting a value according to the characteristics of multiple angles, for example: splitting X glass balls according to color, size, and price. Among them, "color", "size" and "price" refer to dimensions, and specifically "red", "black", "big" and "expensive" refer to nodes under the dimension.

[0071] Multi-dimensional operations basically follow the following principles: first determine the specific value of one or more dimensions, and then calculate another dimension (for example, the calculation method for the balance of three dimensions is to calculate one of the dimensions first, and then use the value of one of the dimensions Each node is used as the total to calculate the amount of another dimension; after the calculation is completed, the nodes of the first two dimensions are used as the total to calculate the value of the third dimension).

Abstract

The invention discloses a production scheduling method based on an equilibrium principle and capacity limitation, which comprises the following steps: S1, defining constraints of each level and maintaining a hierarchical structure through a constraint definition module so as to define a splitting object of a product / period; s2, splitting calculation is carried out through a scattering calculation module, and the scattering calculation module comprises the following steps: determining a splitting dimension; splitting according to a proportion; deducting an overrun part; distributing the deducted part to other nodes in proportion; judging whether distribution can be carried out or not, and if not, prompting and ending the process; and when allocation is available, the process is directly ended. According to the method and the device, a proportional distribution result can be more accurate by using a proportional disassembly mode, and multi-dimensional proportional disassembly can be met; the layer-by-layer splitting mode can ensure that the error of production scheduling is local and the overall situation is not influenced.

Description

technical field [0001] The invention relates to the technical field of production scheduling in industrial production, in particular to a production scheduling method based on the principle of equilibrium and capacity limitation. Background technique [0002] In the production scheduling process of industrial production, in order to make full use of production capacity, it tends to balance products and work cycles. In order to meet the balanced scenario, the production quantity needs to be allocated according to a certain ratio (working hours in the cycle, the total amount of different types of products). [0003] The traditional method of production scheduling is directly in place in one step. For example, if you need to arrange a production plan for a month, you will directly arrange how many units per day. Such an approach will lead to large adjustments to the later plan if there are production scheduling errors in the early stage. [0004] In addition, in the tradition...
