Editing Decide Modules

Decide modules can be added to the flowchart view via dragging and dropping (see Editing Create Modules for a demonstration) and edited by double clicking on the module. There are 4 types of Decide modules.

2-way by Chance

This type of decide module will route entities one of two ways according to a given percentage. The percentage is specifed by the user and relates to the proprotion of entities that are routed to the True exit point.

2-way by Condition

This type of decide module will route entities one of two ways depending on the condition. There are multiple types of conditions.

Variable

Arena evaluates a variable-based expression and routes to the True exit point if the expression is true or the False exit point otherwise.

Attribute

Arena evaluates an attribute-based expression and routes to the True exit point if the expression is true or the False exit point otherwise.

Consider the example of simulating queuing at a supermarket. If the entity attribute QueueNumber is equal to 2 then that entity will be routed to the True exit point which leads to processing at Counter 2.

Entity Type

Arena will route all of entites of the specifed entity type to the True exit point and all other entity types to the False exit point.

Consider the example of simluation an egg sorting factory. Suppose an egg can be a size 6 egg or a size 7 egg depending on its weight. If an egg has the Entity Type 'size 6 egg' then that entity will be routed to the True exit point which leads to the C ollection of Size 6 Eggs while all other eggs are routed to the False exit point which leads to the Collection of Size 7 Eggs.

Expression

Arena evaluates the expression and routes to the True exit point if the expression is true or the False exit point otherwise.

N-way by Chance

N-way by Condition
