What are the common application scenarios of tree classification diagrams?

1. Cross-classification can quickly obtain information about things in different classification dimensions, which is convenient for finding and analyzing. Applicable scenarios Tree classification is suitable for classification problems with clear hierarchical relationships and common attributes.

2. Usage scenarios: Tree diagrams are widely used in many fields, such as organizational charts, file systems, biological classifications, etc. For example, in the organizational chart, the tree chart can clearly show the hierarchical structure of the company, the relationship between departments and the subordinate relationship of the position.

3. Application in chemistry In chemistry, there are often some types of questions that classify substances, among which tree classification and cross-classification are mainly applied. Generally speaking, tree classification is a sub-concept and a parent concept of the relationship contained between matter within a certain range.

4. Tree structures can be used to represent hierarchical structures, such as organizational structure, file system, HTML documents, etc. In the algorithm, tree structure is also used to realize search, sorting, storage and other functions. Common tree structures include binary trees, balanced trees, B trees, etc.

5. The star type is used in the computer room of Internet bars or colleges. The bus type is mainly used in the trunk network segment, such as the external transmission part of the bank head office and the head office. The tree type is mainly used in the branch network segment, such as the branch network.

Enterprise Planning and Decision-Requirements and Methods of Scientific Decision-making

Decision-making must be based on the established goals, use scientific means, evaluate the possible implementation results of various schemes, and select the optimal scheme. Decision-making always chooses several plans under certain conditions. Selection includes two aspects: one is goal selection, that is, finding optimization goals; the other is method selection, that is, finding the best way to achieve the goal.

Multiple Thinking Model 4: Decision Tree - How to Make Decisions in the Face of Uncertainty.

1. Bayes' analysis method is to constantly add new information to the process of reasoning and decision-making, which is the "decision tree" to be talked about in this article. The decision tree is a thinking tool that helps us make higher probability of correct decisions in the context of incomplete information.

2. The core of the pluralistic thinking model includes: (1) essential thinking: try to analyze the essential problems behind specific problems; (2) interdisciplinary thinking: use the principles and solutions of other fast-growing fields to solve specific problems in the field and achieve a downsizing blow to specific problems.

3. The decision tree method can simply and clearly help the decision-making level of enterprises analyze the business risks and business direction of enterprises.
