Generating threat and movement map

Hello,

i am trying to create an AI for a strategy, which input will be a generated "map". This map will contain all the information necessary to make a decision, but to make things easy, i wanted to generate this map using specialized sub-maps. These sub-maps could be for example:

• if the terrain is walkable (basically a simple nav mesh).
• if there is danger present on map (which should be generated based on position of enemies in scene)
• if there are friendly units, to which the unit is trying to stick close by
• if there is a objective a unit is trying to get to (path player move order for example, possibly way point generated by path finding. This type of map can be specific for a single unit for example, but to keep things compatible i want to use the same approach here also)
• etc, possibly many more as needed

Some of those maps will be static, some of them are supposed to be dynamically generated every update.
By using all relevant maps for a unit, evaluation of surrounding will be created, and used for movement / planning.
Then, when a unit will be trying to move around the map, it will move (steer) based on this map, and will move in direction of best value.

I wish to proceed in this way because i want to

a] separate AI in distinct chunks so it is more manageable, and every AI chunk only solves single issue,
b] the result of those AI will be available for all units, so the "thinking" will be done the least amount of times needed​

I tried google this topic, but nothing came up (to be exact, a lot non related things came up, but none were very useful).
Can anyone help, or point me in the right direction please?

Thank you

PS: this is not supposed to be a flow field attempt

 

This is late so I'm not sure if its still helpful or not, but the approach you're looking for is called "influence maps".

There's a bunch of good intros to the subject:

This is a very common approach to AI, and it's quite solid if well designed.
