Set up Price Rules

Price Rules are intended to update Task price automatically, for example, every day. This function helps promote slow Tasks by gradually increasing the Task price.

Add Price Rule

To add a Price Rule for a specific Task:

  1. Go to Run Task > Advanced Options > Adjudication.

  2. Select a Price Strategy in the appropriate dropdown.

  3. Set all the Price Strategy parameters:

    • Max Price
    • Increment price time
    • Increment price value
    • Max price
    • Min price

  4. Click the Save button and save the Task.

You can also edit main rule parameters by clicking the Switch to Advanced View link.

 when
  $ctx: PriceRuleContext(initialized == false);
 then 
  # insert processed facts into memory
  
$ctx.getProperties().put('minAmount', new Double(0.1));

$ctx.getProperties().put('delta', new Double(0.1));
$ctx.getProperties().put('factor', new Long((new Date().getTime() - $ctx.getRun().getStartDate().getTime())/(60000)));
  $ctx.getProperties().put('newAmount', 
                           (Double)$ctx.getProperties().get('minAmount') + (Double)$ctx.getProperties().get('delta') * (Long)$ctx.getProperties().get('factor'));
  $ctx.updateWorkingMemory();
  # move to business rules
  kcontext.getKnowledgeRuntime().getAgenda().getAgendaGroup("calculation").setFocus();
end
rule "1. Set new price" 
agenda-group "calculation"
dialect "mvel" 
salience 100
 when
  $ctx: PriceRuleContext(initialized == true);
  eval($ctx.getProperties().get('newAmount') < $ctx.getProperties().get('maxAmount'));
 then 
  $ctx.setNewReward(Math.round((Double)$ctx.getProperties().get('newAmount') * 100)/100.00);
  $ctx.logExecutedRule(kcontext.getRule().getName());
end
rule "2. Set max price" 
agenda-group "calculation"
dialect "mvel" 
salience 90
 when
  $ctx: PriceRuleContext(initialized == true);
  eval($ctx.getProperties().get('newAmount') >= $ctx.getProperties().get('maxAmount'));
 then 
  $ctx.setNewReward(Math.round((Double)$ctx.getProperties().get('maxAmount') * 100)/100.00);
  $ctx.logExecutedRule(kcontext.getRule().getName());
end
rule "3. Logging data" 
agenda-group "calculation"
dialect "mvel" 
salience 10
 when
  $ctx: PriceRuleContext(initialized == true);
 then 
  $ctx.logData();
end
