(The network solution technology is to use a directed network graph to express the sequence of each office in a plan and the logical relationship with each other; then calculate the time parameters to find out the important routes and available maneuvering time in the plan; in accordance with certain optimization. policy, and constantly improve and optimize the plan arrangement, so that the plan can achieve overall optimization; and during the implementation process of the plan, by checking, controlling, and adjusting to ensure the implementation of the plan policy on schedule)
