Disposal Domain Model

Model Diagram

The following diagram shows the aggregates of the disposal subdomain.

The Collection Point Aggregate is very important as it contains information about the dumpsters' position. Indeed, the dumpster is strictly correlated to the collection point it is contained into.

Domain Events

The Dumpster Aggregate deals with the following events:

  • Citizen Disposal Event: generated when a citizen disposes of some waste.
  • Dumpster Volume Update Event: generated when the volume sensor detects a disposal or a collection.
  • Dumpster Availability Update Event: generated when the dumpster becomes available or unavailable.
  • Opening Event: generated when the dumpster is opened.
  • Closure Event: generated when the dumpster is closed.
  • Mission Request Event: generated when the dumpster's occupied volume exceeds its threshold.

Domain Factories

  • Dumpster Static Factory: generates dumpsters defining their TypeOfDumpster.

Domain Invariants

  • TIMEOUT = 30 seconds.
  • OCCUPIED_VOLUME_THRESHOLD = 75%.
  • occupiedVolume < capacity.
  • Citizen Disposal Events are accepted iff isAvailable.
  • Opening Events are accepted iff isAvailable.
  • isAvailable = isWorking && occupiedVolumePercentage < 95%.
  • TypesOfWaste are mapped to one and one only Color, and vice versa.
