Starting from the overall process of the extraterrestrial surface exploration mission, we gradually expand the process details, refine and define the sub-processes layer by layer, assign each activity to the executor, and identify the exchange items between the executors in the activities. In the Op-Pr view of the operation process, the various operation activities of the extraterrestrial surface exploration mission system at different levels identified by the activity process modeling are sorted and classified to form an operation activity list; For each executor in the runtime architecture, based on the results of the runtime architecture activity design, all activities that each executor needs to perform are summarized and organized, and summarized according to the logic of the execution activities. In the runtime state Op-St view, the behavior of each executor is comprehensively described by establishing a runtime state machine model of the executor. The executor state machine is run according to each scenario in the activity design to verify whether the activity design scheme of each scenario can be reproduced, thereby verifying the logical consistency and completeness of the behavioral design of the running architecture scheme.

Strategic phase planning, the expected planning of various resources, and the design of various start and end times in the roadmap design are all necessary input information for project management design.
