TheGameOfRules

We are looking for a decision model capable to decide if a ship can enter a Dutch port on a certain date. The rules for this challenge are inspired by the international Ship and Port Facility Security Code. They were originally developed for The Game Of Rules, a publication of the Business Rules Platform Netherlands. The authors: Silvie Spreeuwenberg, LibRT; Charlotte Bouvy, Oelan; Martijn Zoet, Zuyd University of Applied Sciences. The rule set is not intended to be complete for all possible cases.

Here are the rules:

  1. The hold of a ship must be considered clean if the hold does not contain remainders of cargo.
  2. An unloaded ship may only enter a Dutch port if the ship complies with the requirements of the Inspection for unloaded ships.
  3. A ship must comply with the requirements of the Inspection for unloaded ships if the ship complies with all of the following: a) the ship meets the safety requirements for unloaded ships; b) the ship has a certificate of registry that is valid.
  4. A ship must be categorized as large if the total length of the ship is at least 80 meters.
  5. A ship’s hold contains remainders of cargo if the residual cargo measurement is higher than 0.5 mg dry weight per cm².
  6. A ship only meets the safety requirements for unloaded ships if the ship complies with at least one of the following: a) the ship meets the safety requirements for small unloaded ships; b) the ship meets the safety requirements for large unloaded ships.
  7. A ship only meets the safety requirements for large unloaded ships if the ship complies with all of the following: a) the ship is categorized as large; b) the hold of the ship is clean; c) the hold of the ship is double hulled.
  8. A ship only meets the safety requirements for small unloaded ships if the ship complies with all of the following: a) the ship is categorized as small; b) the hold of the ship is clean.
  9. A ship must be categorized as small if the total length of the ship is less than 80 meters.
  10. A ship’s certificate of registry must be considered valid if the date up to which the registration is valid of the certificate of registry is after the current date.
