Activity Based Classification

ABC classification analysis method called Pareto or Barreto analysis, Platon analysis, for primary and secondary analysis method, ABC analysis method, classification management method, key management method, ABC management, ABC management, Barrett analysis, we usually called "80 to 20" rules. It is based on things in the technical or economic aspects of the main characteristics of the classification queue, distinguish between the focus and general, so as to identify a different way of management analysis. Because it divides the analysis object into A, B, C three kinds, so also called ABC analysis method.

ABC classification was pioneered by Italy economist Vilfredo Pareto. In 1879, Pareto in the personal income distribution research, found that minority income accounted for the majority of all income, and most people's income is only a small part of this relationship, he will use the diagram, is the famous Pareto map. The core idea of the method is in many factors that determine a thing in setting priorities and identify key factors but few effect on the things and most of things but less secondary factors. Later, Pareto's law was constantly applied to all aspects of management. 1951, management scientist Deckard (H.F.Dickie) will be applied to inventory management, named ABC method. From 1951 to 1956, Joseph Juran introduced the ABC method into quality management, which was used to analyze the quality problem. In 1963, Peter Drucker (P.F.Drucker) will promote this method to all social phenomena, so that the ABC method to improve the effectiveness of enterprises to achieve universal application of management methods.

This rule by sorting the same kind of problem or project, to identify a few controversial. Pareto through long-term observation found that: 80% of the United States only mastered the property of the people, while the other 20% of the people have mastered the country's property of 80%, and many things are in line with the law of the. So he applied this law to production. His main point is that you will get better results by allocating time and power to a small number of a class a total. Of course, ignoring B and C classes is also dangerous, in the Pareto rules, they get relatively little attention to class A.

Specific steps of ABC classification

Edit this paragraph]

1, collect data

Collect data according to analysis object and analysis content. For example, to analyze the cost of the product should collect product cost factors, composition of product cost data; to analysis for a system to engage in value engineering, it should be in the local collection system function, the local cost data.

2, processing data

To collect the data collected, according to the requirements of calculation and summary.

3, ABC analysis table

ABC analysis table columns are as follows: the first item name; the second column total number of species, namely each kind of goods are a number of species, number of species is the cumulative actual number; the third column is the cumulative percentage of total number of species, number of species on the percentage of the total number of species; the fourth column fifth column average inventory goods price; the sixth column is fourth; the average stock price multiplied by the fifth column column, the average amount of funds used for a variety of items; the seventh column is the average amount of funds used cumulative amount; the cumulative percentage of average occupancy of eighth bar funds; Ninth column classification results. Tabulation according to the following steps: the second step has been calculated to calculate the average amount of funds to large queue mode, from high to low fill in the table in the column sixth. This column shall prevail, will be the name of the article filled in the first column, items into fourth columns, the average inventory filled with fifth columns, in the second column by the 1, 2, 3,...... number, the cumulative product. Since then, calculate the number of species, the cumulative percentage of fill in the third column; calculate the average amount of funds used in the seventh column; the cumulative amount of funds used to calculate the average cumulative percentage, fill in the eighth column.

4, according to ABC analysis table classification

According to the ABC analysis table, the cumulative percentage of species were observed in the third bar and eighth bar average cumulative percentage of the amount of funds used, the cumulative percentage of species was 5 15% and the average amount of funds used for a cumulative percentage of about 60 80% of the first few items identified as class A; cumulative number of 20 items per cent to 30%. While the average amount of funds used for a cumulative percentage of 20 30% items, identified as B; the rest of class C, class C and class A is on the contrary, the cumulative percentage of species was 60 and 80%, the amount of the cumulative percentage of the average occupancy of funds was only 5 - 15%.

5, drawing ABC analysis

The cumulative percentage of species as the abscissa, the cumulative percentage of the amount of funds used for vertical coordinate analysis are provided in tables third and eighth columns of the data according to the ABC, take the points in the coordinates graph, and the connection point is plotted curve, ABC curve.

According to ABC analysis curve corresponding data, according to ABC analysis table to determine A, B, C three categories of methods, in the figure marked A, B, C three categories, then made ABC analysis chart
