Modeling a supply chain

A system for modeling a supply chain, the system comprising:

• a host system with a processing circuit responsive to executable instructions which, when executed by the processing circuit facilitates:
• modeling a storage element in the supply chain as a place node;
• modeling an activity in the supply chain as a transition node, the transition node comprising at least one of:
• an immediate transition node;
• a timed transition node;
• and
• a substitution transition node;
• modeling an item moved through the supply chain as a token, the token comprising multiple attributes associated with the item;
• linking the place node to the transition node with a directed arc, the directed arc indicating the direction of token movement between the place node and the transition node;
• organizing the linked place and transition nodes as a supply chain model representing the flow of items through the supply chain;
• and
• defining performance metrics for the supply chain model;
• and
• a storage device for storing the supply chain model.

A computer program product for modeling a supply chain, the computer program product comprising:

• a storage medium readable by a processing circuit and storing instructions for execution by the processing circuit for performing a method comprising:
• modeling a storage element in the supply chain as a place node;
• modeling an activity in the supply chain as a transition node, the transition node comprising at least one of:
• an immediate transition node;
• a timed transition node;
• and
• a substitution transition node;
• modeling an item moved through the supply chain as a token, the token comprising multiple attributes associated with the item;
• linking the place node to the transition node with a directed arc, the directed arc indicating the direction of token movement between the place node and the transition node;
• organizing the linked place and transition nodes as a supply chain model representing the flow of items through the supply chain;
• and
• defining performance metrics for the supply chain model.
