Items, Paths and Flows

Item Palette appearing in the Planimate sidebar

Dynamic Entities that enter, move through and exit the system by way of passing from one object to another are called Items. Planimate® organises groups of like Items into CLASSES. They are found in the Item Palette.

A Path is a sequence of steps followed by an Item defining its movement from one object to another. The sequences are defined by the modeller for each item class. Items step from object to object through the system during a simulation and this stepping is animated. Items in each Class share the same paths through the system.

The collection of paths that are defined for an Item Class is called the Flow. An item entering the system steps from object to object along a path in its flow. During a simulation run, many items can move along the flow concurrently.

A Planimate® system model can contain many Items, and Item Classes. The movement of Items is normally animated during a simulation. Path editing is undertaken in Flow Edit View.

Agents

Main article: Agent

Agents are special types of items that interact with some objects in a different way to standard items. Agents play a role as transporter of other items. An agent can pick-up one or more items at a location, and then move them to another location and drop them in the new location.

Item Table References

Main article: Item Table References

Items can carry references to table in a model so it can be referenced anywhere in the model. An item table reference only allows reading of the table.

To use an item table reference, in the Item Edit menu, create a named table reference for the class, say called "test". From now on, when editing a routine with that item flow involved and you select a table, you will now have "<item> test" available, enabling use of the item's reference to supply the table as well as the original tables and <Dynamic>.
