When the personnel management module 2 predicts the employee's job entering and leaving conditions, the external environment will affect the employee's job entering and leaving conditions, so that the rule needs to be summarized first, and then the total net job leaving number, the job in progress staff wage structure and project prediction period are predicted more accurately, so that the personnel management module 2 includes: the project period acquisition module 21 is used for acquiring months contained in a project scheduled period of an enterprise and marked as project months, and predicting and counting wage distribution conditions of total net-away staff in the productivity statistics module 24 through a big data model, and counting wage structure conditions of staff; a month influence module 22 for predicting, based on the basic data, the number of net departure persons for which the month of each item is influenced by the month factor, where the item remaining time refers to a time when a part of the item is not yet performed as compared with the current time, for example, a time when an enterprise item needs to be from 3 months to 9 months, and if the current time is the last day of 5 months, the item remaining time refers to a time after the beginning of 1 day of 6 months, typically a time of 6 months to 9 months; the pressure influence module 23 is used for predicting the number of net job departure people, which are influenced by project pressure, of each project month in the project residual time according to the basic data and the project pressure of the project period prediction module 25, and the working pressure can influence the job departure probability of enterprise workers in the working process of the workers; a productivity statistics module 24 for counting total net departure persons according to the net departure persons of each month output in the month influence module 22 and the pressure influence module 23, and predicting productivity of the incumbent person at any time in the enterprise engineering according to the total net departure persons, the initial persons and the project pressure, wherein the productivity represents workload of the incumbent person in a certain period of time, such as workload of one day, one week or one month, at any time; the project period estimating module 25 is configured to calculate the estimated period of each project month of the project in the project remaining time according to the total net job departure number of the productivity statistical module 24, and calculate the project pressure of each project month in the project remaining time according to the estimated period and the initial predetermined period of the enterprise, where the estimated period is longer than the predetermined period, the larger the project pressure is indicated, and at this time, in order to ensure that the project is completed in the predetermined period, the manager needs to increase the labor intensity by overtime or other modes, i.e. the larger the project pressure is, and the easier the job departure probability of the worker is.
The weather varies from month to month in a year, for example, the outdoor temperature is high in summer, and outdoor projects are easy to raise the off-duty probability of personnel of the projects, so in order to accurately evaluate the influence of months on the personnel flow condition, the month influence module 22 includes:

In evaluating the influence of the project pressure and the staff flow condition of different project months in the project through the basic data, it is necessary to select month data equal to the project pressure of different project months from the basic data, so as to estimate the net departure staff number according to the data, and the pressure influence module 23 includes: a pressure correspondence module 231 for acquiring project pressure data corresponding to each project month in the project remaining time from the project period estimation module 25, and acquiring the number of outliers in the month which is the same as the project pressure value and the number of staff entering in the month from the basic data; a third net job leaving number module 232 for calculating net job leaving numbers of the months of the item affected by the item pressure in the remaining time of the item according to the job leaving number and job entering number data acquired by the pressure correspondence module 231; the calculation formula of the number of net departure persons of each project month influenced by project pressure in the project residual time is as follows:

Since the number of incumbents for different project months is different, when a project is performed, there is a difference in the amount of the project that can be completed in a fixed period of time, that is, there is a difference in productivity, in order to accurately calculate the productivity of each project month in the remaining time of the project by the productivity statistics module 24, the module includes: a total net off-staff number module 241 for calculating the total net off-staff number of each item month in the item remaining time according to the net off-staff number influenced by the month outputted by the month influencing module 22 and the net off-staff number influenced by the item pressure outputted by the pressure influencing module 23; the calculation formula of the total net departure number is as follows:
