For some projects that are ready to go online or have just been launched, there are not enough logs in the system for us to analyze. At this time, the original data analysis method we mentioned earlier is no longer applicable. For such cases, our more common method is to find a system similar to the project and evaluate the possible usage model of the project through this kind of simulation.

Analogical simulation

For some projects that are ready to go online or have just been launched, there are not enough logs in the system to provide us with analysis. for this kind of situation, our more common method is to find a system similar to the project. this simulation is used to evaluate the possible usage model of the project.

Because there are various variables in the user's mode of using the system, whether the modeling result of this kind of simulation is accurate depends on whether the project to be modeled is close enough to the analogous project we find.

The more general method can choose to use distance discriminant method, that is, select some factors that can describe the state of the system and use changes, by comparing the similarity of these factors between different projects, give the difference between the target project and each project participating in the comparison, the smallest difference value is the smallest distance, that is, the most similar project.

Some of the key factors are as follows:

1. Initial data: mainly refers to the system parameters, such as the number of basic data, the number of entries, such as the number of documents or reports, the number and complexity of formulas, etc.

two。 Usage scale: mainly the number of users and business data, such as the total number of users, the number of users in different roles, and the monthly increase in business data.

3. Life cycle: mainly refers to business similarity and user habits, such as whether the expected peak period of the business is consistent, whether the user's operating habits are consistent, etc.

4. Peripheral interface: is there a peripheral interface?

5. .

When determining the difference value, we give each key factor a weight, then grade the difference degree of each factor, and calculate the total difference value according to the score and weight of each factor. select the project with the smallest difference value is the project with the highest degree of analogy, we can take the use of the project as a sample for simulation modeling.
