Logistics

Logistics in Moons of Ardan is more relaxed than most city builders. It consists of two parts: storage and resource transportation.

## Storage

### Stockpile

Each production building has its own local output stockpile for temporarily holding produced resources. This stockpile typically holds 5 resources, but some buildings have a different sized stockpile. Each building's stockpile size is listed on the building's wiki page in the building infobox. Within the game, the current number of resources in the stockpile can be seen by clicking on the building to open its building info panel and looking at the number displayed on the storage icon. Mousing over the storage icon will reveal a tooltip with additional details including the total stockpile size.

When a building's stockpile is full, the info panel icon will turn red and the building will stop producing resources until space in the stockpile is made available. Additionally, a floating storage icon will appear over the building. A red floating icon indicates that global storage has room for the resource, but no transporter has come to pick the finished resources up. A cluster of red floating icons is a clear indicator that more transporters are needed in the area.

A yellow floating icon indicates that both the local and global storage is full for the given resource. Yellow icons don't necessarily mean there is a problem; they simply indicate full storage for that resource. If more global storage is desired, additional city centers and warehouses can be constructed/upgraded. Alternatively, the production buildings can be paused to free up additional workers until more resource production is once again needed.

### Input Storage

Each building that requires input resources also has an input storage and this storage is typically enough for two days of supplies. For example, the clothes factory requires 2 Fabric/day. Its input storage is able to hold 4 Fabric. Buildings with multiple inputs have a separate input storage for each resource. A well supplied building will have one batch in production, and resources in storage for two more batches.

### Global Storage

Warehouses (all versions) and city centers both increase the total moon global storage capacity. For asteroids, the asteroid hub and asteroid warehouse similarly increase the global storage capacity of the asteroid. These buildings also function as access points to the global storage and resources dropped off at one of these buildings are instantaneously available to pick-up at any of them. There is no travel time needed for the resources to travel between them, only for transporters to move resources from the access point to a production building and back.

## Resource Transportation

### Local Transporters

Each production building has its own worker that will attempt to fetch the input resources needed by the building from a nearby (75m) production building that produces the input resource and has some in its building stockpile, or from a global storage access building. The closest source for the resource will be selected. Minimizing transport round-trip time will speed up your production chains.

### Global Transporters

Each warehouse (all versions) and city center employ workers to transport goods on a moon and every worker is a global transporter. For asteroids, the asteroid hub and asteroid warehouse similarly supply transporters for asteroids. Global transporters gather finished resources from production buildings within their service radius and return them to the global supply. They do not supply resources to production buildings.
