Missions
Revised : 5 Aug 2020
Missions are outdoor expeditions undertaken by settlers.
Normally, the settlement prioritizes what missions to conduct at a given time based on its needs.
While Missions are generated automatically by mars-sim, user may also create any particular missions manually via the Mission Tool.
Also, all ongoing missions are tabulated at the Mission tab in the Monitor Tool.
The 12 types of Missions are as follows :
| Type of Missions |
|---|
| Areology Study Field Mission |
| Biology Study Field Mission |
| Building Construction Mission |
| Building Salvage Mission |
| Collect Ice |
| Collect Regolith |
| Emergency Supply Mission |
| Exploration |
| Mining |
| Rescue Salvage Vehicle |
| Trade |
| Travel To Settlement |
See the on-going project #12 in https://github.com/mars-sim/mars-sim/projects with regard to modeling the Mission Planning aspect of the simulation.
A typical mission comprises a few phases as follows :
| Type of Phases |
|---|
| Organizing |
| Approving the Mission Plan |
| Embarking |
| Travelling to Next Nav Point |
| (Various Stages depending on the Mission) |
| Disembarking |
At the beginning, if the starting member cannot find mission capable personnel or adequate resources, he/she may fail to successfully organize the excursion.
Also, during the Approval phase, a senior leader such as a commander, sub-commander, or a chief will review the mission plan and provide a composite score that is made up of the following 10 areas :
| Type of Scores | Description |
|---|---|
| (1) Rating | mission lead's cumulative job rating |
| (2) Relationship | mission lead's relationship score with the reviewer |
| (3) Qualifications | mission lead's mission qualification |
| (4) Objective | does this mission fit into the settlement's overall objective |
| (5) Emergency | is this a rescue or resupply mission ? |
| (6) Site Value | how accessible or how good are the collection rates are the sites to be visited |
| (7) Distance | how many km is the proposed distance traveled |
| (8) Leadership | how good is the mission lead's ability to lead |
| (9) Reviewer Role | the weight of the role of the reviewer. (e.g. The commander as the reviewer has the highest weight) |
| (10) Luck | add a little bit of randomness |
The Mission Plan must be reviewed and scored a few times separately (hopefully by up to 5 different senior leaders).
It will combine these scores and compute an average score.
If the average score passes a certain threshold value (also known as the passing score), then the Mission is approved.
Note that during each review process, the passing score is being recomputed and is therefore different each time.
We design it this way so that a sliding scale will increase or decrease the passing score dynamically, based on the trending from previous mission planning scores.
