The optimization method is to arrange experiments reasonably under the guidance of mathematical principles, so as to find the best scheme in production and scientific experiments as soon as possible with as few experiments as possible. Namely the optimization method.

Master planning method, also known as network planning method. Overall planning method is a mathematical method of production organization and management. It takes the time required for the working procedure as a parameter, reflects the whole picture of the studied system with network diagram and simple calculation method, and finds out the key route and the working procedure on the key route that has influence on the overall situation, so as to make practical arrangements for all the working procedures of the project.

The basic idea of master planning method is:

First of all, starting from the overall progress of the tasks to be managed, taking the duration of each task as the time factor, the overall plan is made according to the sequence and relationship of tasks, so as to reflect the whole picture of tasks and realize the modeling of management process. Then calculate the time parameters, find out the key work and key lines in the plan, and reasonably arrange the people, money and materials needed for each task by perfecting the network plan, so as to get a reasonable plan and put it into practice.

In addition, we can also make quantitative analysis of various assessment indicators, and effectively supervise and control the implementation of the plan to ensure high quality assurance to complete the task.
