Item
Models a stock-keeping unit (SKU) within an inventory system. An ItemType is associated with a unit cost, a weight, a cube (length × width × height), and optionally a leadTime distribution used when this item type is stocked at a location with non-zero replenishment lead time.
The caller is responsible for stream-number assignment when constructing the leadTime source; ItemType does not draw values from it directly.
Parameters
the parent model element
an optional name; defaults to a generated unique name
the weight per unit, must be > 0; defaults to 1.0
the cube per unit, must be >= 0; defaults to 1.0
an optional replenishment lead-time source; may be null See sc.inventorylayer.ItemType
Constructors
Properties
Cube per unit; must be >= 0. Re-seeded from initialCube at each replication start.
The initial cube per unit (>= 0), applied to cube at the start of each replication. A control. Cannot be changed during a replication.
The initial weight per unit, applied to weight at the start of each replication so replications begin under identical settings. A control. Weight must be strictly positive: the control-set path stores a clamped (>= 0) value without throwing, and a value of 0 is rejected when the initial value is applied at replication start. Cannot be changed during a replication (initial values are replication initial conditions); the live weight remains internally managed.
Optional replenishment lead-time source.
Unit cost; must be >= 0. Defaults to 1.0.
Weight per unit; must be > 0. Re-seeded from initialWeight at each replication start.
Functions
This method should be overridden by subclasses that need actions performed prior to each replication. It is called prior to each replication and can be used to initialize the model element. It is called before initialize() is called.
This method should be overridden by subclasses that need actions performed when a model element is removed from a model
