network-based prism. The solution of the problem includes several critical activity
opportunities and their corresponding space-time paths. In this way, an activity
participation plan for each person can be scheduled.

7.5 Experiments

This section describes an activity scheduling scenario which states that four people
in Wuhan, China, need to meet each other within a week. They are a professor,
a postgraduate student, a government official, and a retailer. Table 7.2 gives their
detailed attributes and Table 7.3 their requirements for joint activity participation.
There are three activities in which they want to participate:

1. Persons P1 and P2 need to carry out a business survey in five business centers
among nine candidate business centers (“Qunguang Square”, “Xudong shopping
mall”, “Hanzheng Street”, “Han Street”, “Luxiang Square”, “Wangjiawan”
in Hanyang, “Central South shopping mall”, “Wuhan Tiandi”, and “Wuhan
shopping mall”), which are distributed in Wuhan, China.
2. Persons P1, P2, P3, and P4 need to have a meeting to discuss the business survey.
This activity should be scheduled after the first activity.
3. Persons P2, P3, and P4 want to enjoy a weekend entertainment together.
