Business Rules

Use this page to define the business rules for your zones. Rules define the circumstances that trigger alerts.

Note: You need to define a zone before you can define a rule for it.

When you define a rule, you can check for future events, but not for events that have already happened. For example, if a person is already in Zone A and you then define a rule that items defined in the Person class cannot enter Zone A, the result is no alert. No alert occurs because rule checking is triggered by zone entry and exits events, which did not occur in this situation. The logic is similar with a rule for duration of stay. If a person has already been in Zone A for 30 minutes, and you define a rule that the person cannot stay in Zone A for longer than 10 minutes, no alert occurs.

Click the type of business rule you want to work with. Business rule types include:

A list of rules displays that are of the business type you selected. Click Add to define a new rule. Click Delete to delete an existing rule or click Edit to edit details for an existing rule.

The following fields are available for all business rules except for Visitor Escorting:

Zone Exit Restriction

This rule type allows you to specify the times when specific classes or groups of persons or items must not leave specific zones.

This rule type allows you to specify the maximum number of persons or items satisfying the specified criteria that can be in a specific zone at one time.

Visitor Escorting

This rule type allows you to specify rules that enforce the escorting of visitors and that govern how visitors will be escorted at the location. This rule type has less configuration options than the others, and its activity cannot be temporarily restricted.

Complete the following fields to create a new rule:

Items Association

This rule type allows creating associations between items. An association is created when two items fulfilling the specified filtering criteria are close to each other for a configurable period of time. Even though the rule can be applied to classes and group of items, associations are always created between two individuals.

Complete the following fields to create a new rule:

Tips for using this rule:
  • Both the container tag and the associated tag must move into the target zone after the zone-related rule has been defined.
  • The associated tag must be "inside" the edge length of the container tag longer than the minimum time without interruption.
  • The base item must be the last item moving because the association rule is evaluated when the container items move.
