Ever wonder why this activity isn't scheduled where I think it should be? What exactly did PSO do to schedule it to a particular resource or not to the other one? It's a common challenge. You have this great software PSO, that's supposed to make complicated plans, but sometimes, SCHEDULING feels like a mystery. Totally. But what if I told you there's this feature that can actually explain those decisions? Oh, that's where the Explanations functionality comes in. Okay. So instead of just seeing the schedule and being confused, I can actually ask why did you do that? Exactly. The explanations page in PSO Workbench is your go-to for understanding not just what was decided, but why. So, it's all about transparency, helping users trust the system. Absolutely. You can see why an activity isn't scheduled or why it ends up being scheduled to a specific resource. Makes sense. But how does it actually work? Is it like some huge log file that's impossible to read? Yeah. No. Oh, not at all. The system shows all the places it tried to put an activity nicely grouped by resource and then by shift. So, if I'm scheduling a maintenance activity, I could see if it tried to put it on different resources or during different shifts. Exactly. And for each attempt, you can see if it worked or not and the reason why. Like, was the resource busy, or was there a shift conflict? Exactly. Maybe the vehicle wasn't right for the job, or Something else is already scheduled, but you can go even deeper. Deeper? And don't forget about the trust. When people see the logic behind the decisions, they trust the system more and use it better. Explanations is super helpful for troubleshooting. I'm starting to see how useful this could be to understand how & why activities are scheduled the way they are. It's all about making things clear. Well, imagine you see that certain activities are always hard to schedule. By understanding the DSSE's logic, you can figure out why. So, it's not just fixing single problems, but figuring out patterns and maybe bottlenecks. Exactly. Explanations screen is used to assist in understanding why the activity has not been scheduled or why it has been chosen to be scheduled to a particular resource.​ It provides insights into the underlying reasons why certain scheduling decisions were made. For instance, if an activity was assigned to a particular resource, the Explanations screen can detail why that choice was optimal, citing factors such as the resource's availability, proximity, or specific skills that match the activity's requirements. Alternatively, if an activity remains unscheduled, this screen can highlight the obstacles, such as conflicting schedules, lack of qualified resources in the vicinity, or other constraints that prevented a viable scheduling.
