java.lang.Object
org.maxicp.cp.examples.utils.SMICInstance
public class SMICInstance extends Object
A Single Machine with Inventory Constraints (SMIC) instance.

A SMIC problem consists of scheduling a set J of n jobs split into two:

  • the loading jobs J+ (type = 1, inventory delta > 0)
  • the unloading jobs J- (type = 0, inventory delta < 0)
Each job has a release date, a processing time and an inventory modification delta. An initial inventory and the capacity of the inventory storage are given.

Two file formats are supported:

  • txt — whitespace-separated, one job per line: type processing weight release inventory
  • dzn — MiniZinc data format with named keys
