Class SupplierModel

java.lang.Object
  SupplierModel

public class SupplierModel
extends java.lang.Object

Keeps track of a single supplier and component. There will be two objects per supplier (e.g., pintel will have one both CPU types). Reputation is tracked, predictions can be made about prices the supplier will offer in response to RFQs, and deliveries can be predicted. The ComponentInfo object will update this object at the start of each day with information about offers made and components delivered, and at the end of each day with the offers accepted.
