  2. Hi LizMB, I have a few specific recommendations for you below, but generally I suggest looking into the SimBit models provided on Simio's Support Ribbon. A PDF opens with each model that contains a detailed description, so they are a great tool for learning specific approaches and techniques. A few that I believe are related to your particular problem are "Moveable Operator", "Interruptible Operator","Keeping Worker Reserved", and "Entity Follows Sequence". Worker1 carries both entities to their respective nodes and leaves them in their respective stations after worker(A/B) "checks them" (I used a delay to simulate this check) and then Worker1 moves on. For this objective, I suggest setting up your drop off stations A and B as a Servers. Use the Processing Time property to represent the "check" while seizing both workers needed (see the Operator related SimBit for more information). Make sure all entities are assigned a sequence, so Worker 1 knows where to drop them off. The worker(A/B) only picks up the entity if needed. So if the worker was with another entity in process (like Srv(A/B)), he would go check the new entity so that worker1 can move on, but would return to finish out the first entity to the end. Assign entities that enter the pick up stations a higher priority, and interrupt the Workers at SrvA and Srvb if a pick up task arrives (See Interruptible Operator for more information). Ensure that the Workers have the needed paths to travel to all of the destinations required in all directions. Currently, WorkerA and WorkerB cannot travel to the Outputs of the Servers. Other suggestions: Look into using a Timer Element that could trigger the entity creations at SrcA and SrcB. That should remove the need for Source1 and Sink1. If the Worker's travel doesn't need to be defined by a path, I suggest setting the Initial Travel Mode to 'Free Space Only'. The error message you are receiving is related to the Add-on Processes on the A and B nodes. Whenever Worker 1 enters either of those nodes the process is triggered and tries to complete the process with relation to the Worker. Restructuring the model with Servers in this area should help you get around this issue. Thanks, Ryan
  3. Hi M_A, Just setting the Sequence property to 'Sequence1' should be enough since you set up relational tables. Because you have Maximum Arrivals set to '1', it is going to produce 1 entity type. I would switch your Maximum Arrivals to '35' and number of entities per arrival to '1'. You will also need to set your interarrival time to '0', so all 35 show up at the same time. It might be best to use a second Source object to create your second shift. I would increase the length of the Ride Station Queue in order to see all 6 passengers boarding the Vehicle. I think the network is fine, but hard to debug. Be sure all travel destinations for the Vehicle are possible. Thanks, Ryan
  4. Hi M_A, The sequences in your table are never assigned to the entities before or as they are created. Assigned the sequences by selecting the entity instances in the Facility view, and set the Initial Sequence property under Routing Logic to 'Sequence1'. Also, the Entity Destination Type property on all of your Transfer Nodes, including the outputs nodes of all Servers, must be set to 'By Sequence' in order for the entities to follow the sequence appropriately. Here are a few other things I noticed while looking over the model: All of your Servers only have the capacity to process 1 entity at a time, so for your case only one employee can work in that area at one time. As soon as each employee is done working they will request a pick up 1 at a time. May not be what you are looking for here. The processing times at the Servers aren't linked to the table. You can link them by setting them to 'Sequence1.ProcessingTime'. Be sure to set the appropriate units in the column properties of ProcessTimes. It is hard to see the network that is available for the Vehicle, so one more thing to check is that the Vehicle has all of the needed paths to pick up and drop off the entities. Thanks, Ryan
  5. Hi M_A, It is difficult to determine what could be causing this without seeing the model. Here are a few things I suggest investigating: Ensure that your model run time is set run long enough for all of your entities to flow through your system. To test this, I would set your model run time to Infinity, and create 1 set of 35 employees. Then see how long it take for the model to cycle through all entities. You may be able to use some Animation at this step to see where the entities are getting stuck. Along with #1, I suggest turning on the Model Trace and reviewing the steps taken for each of your employees and the bus. If you are using an unbounded random distribution (for example a normal distribution) for any of your processing times, then the result of that distribution could be something very large. You should be able to see if that is the case within your Model Trace review as well. Lastly, make sure all of your Transfer Nodes are set to route By Sequence and require the bus for transport. Hope this helps. Thanks, Ryan
  6. Hi M_A, 1. This is one is a bit difficult to provide direction on without seeing how the rest of the model is structured. If all your processing times are deterministic and you are using a sequence table to route your entities, then you should be able to add the lunch break into the sequence. Similarly, make sure the sink is included at the end of all your entity sequences. Also, make sure the model run time is long enough to process all employees. That may be why they aren't showing up at the sink. 2. Change your interarrival time to 12 hours, and set your Maximum arrivals to 2. Thanks, Ryan
