Embodiment 1
[0028] Example 1: Data collection and analysis
[0029] Within the scope of Yunnan Power Grid Corporation, the statistics of the province and its subsidiaries in the past two to three years, the number of various materials that meet the existing national standards, and follow the following process to analyze the data:
[0030] 1. Sort the quantity of materials received from high to low;
[0031] 2. Use the calculation formula: the quantity used for this material type / the quantity received for all material models under this category and *100%, to calculate the proportion of each material used in the product type and the cumulative quantity;
[0032] 3. Mark the materials with a cumulative quantity of 1-80% in green, the materials with a cumulative quantity of 80%-90% in yellow, and the materials with a cumulative quantity of more than 90% in red.
[0033] Initial optimization
[0034] According to the results of data analysis, preliminary optimization is carried out. The step...
Embodiment 2
[0053] Example 2: The following combination figure 1 , figure 2 , image 3 The present invention is described further:
[0054] Introduce the "two-eighth principle" into category optimization, analyze different types of materials in each category from the dimensions of the amount and quantity used, analyze the reasons for this situation from the appearance of the data, and finally determine the material Whether to keep.
[0055] Such as figure 1 As shown, a distribution network material category optimization method includes the following steps:
[0056] A. Automatically obtain the historical data of distribution network reserve materials entering and leaving the warehouse;
[0057] B. Establish a distribution network reserve material category optimization calculation model;
[0058] C. Build an audit module that combines automatic ranking recommendations with expert experience;
[0059] D. Generation of intelligent category replacement relationship and category optimiz...

Abstract
The invention discloses a power distribution network material category optimization method, which comprises the following steps of: obtaining distribution network reserve material in-out warehouse historical data, establishing a distribution network reserve material category optimization calculation model, constructing automatic sorting for recommendation, and performing fine tuning optimization by using expert experience, wherein the fine-tuning optimization is that an auditing module is constructed according to information in the aspects of technical development characteristics and geographical environment particularity requirements, fine-tuning optimization is performed through the auditing module, and an intelligent category replacement relationship and a category optimization result are generated. A solution thought is provided for power distribution network material category optimization, a category optimization model is established in a computer, historical data are fully acquired by adopting the computer, traditional manual analysis is replaced by high-speed calculation, errors caused by manual calculation are reduced, the calculation accuracy is improved, and the reliability of a category optimization result is improved. A category optimization method is continually advanced, material use is standardized, and material waste is reduced.
Description
technical field [0001] The invention relates to the technical field of electric power calculation and analysis methods. Specifically, it is a distribution network material category optimization method. Background technique [0002] Category refers to a group of special goods or services that consumers think are related and can be substituted for each other. According to the definition of FBI Best Practices Definition, category management (Category Management, CM) is "the process of cooperation between distributors and suppliers, and the process of treating categories as strategic business units to create better value by creating consumer value in commodities. business performance". Category management is a series of related activities that divide the commodities that are operated into different categories and manage each category of commodities as the basic activity unit of the business strategy of the enterprise. It improves the operating results of enterprises by emphas...
