Entity Attributes and Entity Priorities

Entity data for run-time control, specify entity priorities

You can attach data to an entity using one or more attributes of the entity. Each attribute has a name and a numeric value. Read or change the values of attributes during the simulation. Use the attributes to route or match the entities, and to set the resource amount that the entities acquire.

You can also specify entity priorities to prioritize events.

Serve High-Priority Customers by Sorting Entities Based on Priority

Minimize the time required to serve high-priority customers by using a priority queue and Entity Input Switch and Entity Output Switch blocks. Customers are served based on their service priorities. In this example, two types of customers enter a queuing system. One type represents high-priority customers with high urgency. The second type of customers are lower priority and are served with less urgency. The priority queue places high-priority customers ahead of low-priority customers.
