I am new to Drools planner. I have one issue and wanted to understand how to resolve it best. I am trying to use planner to optimize the scheduling of work orders to resources. I have certain resources that need to be assigned to a work order in a way that maximizes the utilization of the resource. But I have a condition where once a resource is scheduled for a workorder, he/she shouldn't be scheduled for any other work order again during the same day. How do we manage this condition? do we add it as a constraint in the drools rule file so that scoring can handle it or do we write a custom solver phase to check if a solution has this resource assigned to a WO, then skip the resource and proceed with further solution. Please help.
