Hello everyone, I am working on a project for class and am having difficulties assigning workers to specific servers depending on what day it is within the simulation. I have 18 workers and 16 servers. Each worker has their own 25 day schedule. On a given day, there is between 5 and 8 workers on shift and each worker needs to be assigned to 2 specific servers and no other worker should go to those servers on that day. However, due to the different schedules, a given worker will not always be assigned the same rooms they were assigned the previous day. Is it possible to assign each worker a specific server by day? Or is there another way that this might be possible? Thanks in advance for any suggestions! -
Hi I've got a model where the situation is like this: 1. 3 Worker: W1 W2 W3 2. 3 Server: S1 S2 S3 On Monday (work schedule), W1 will work in S1 in the morning and work in S2 in the afternoon. W2 will work on S2 in the morning and S1 in the afternoon. But on Tuesday, W1 will work in S2 in the morning and S3 in the afternoon. W2 will work in S3 in the morning and S2 in the afternoon. The server properties in the secondary resource are "select from the node list." But since the node list for S1 and S2 contain both W1 and W2, and they both have the same hour of working (4+4), when the S1 server seized the resource on Tuesday morning, instead of W1, W2 got allocated instead( W2 should be in S3). I have tried: 1. Using server selection goal to " smallest distance," but it didn't work since the worker will keep swapping the room every day 2. Giving each worker a new initial value and setting the selection goal to "smallest value," but they still have the issue. 3. Try setting idle action for the worker to stay at the node, but sometimes the worker will go to the wrong destination from the first entity, hence no one working in the other room. (2 worker stay together) Is there any method to realize this idea? Thanks in advance

Hi Guys, I have a source producing the entities, which is processed by the server with a worker. server and worker are assigned to work schedule (7Hrs) (12am-7am) arrival model of the server is set to time varying arrival rate. to control the source on holidays. But with current scenario the source is producing the entities on off-shift time. Please help out with a logic, so that source is produces the entities matching to the timings of work schedule. Note: Simulation run is for a period of 1 year. Regards, Alen -
Server Capacity Depends on # of Seized Resources
Liz Millar replied to nObeso23's topic in SI General Discussions
Hi Nicolas, I would investigate the Server property called Initial Capacity. This sets how many units of capacity are going to be available for the Server. You could also change this during the run by Assigning the Server's CurrentCapacity State Variable. I suggest checking out the SimBit titled "Worker Uses Work Schedule". You can access the SimBits in the Support ribbon in Simio. In this SimBit, I recommend changing the Initial Capacity for the Servers. You could set them to '6' or any value. When you run, you will see that the entities only move into the Process Station when they have successfully Seized the Secondary Resource. So even though there is 6 units available only 1 will be use when the Worker is able to process the entity. You can also experiment with giving the Worker a different Initial Number In System value so there can be more Workers. You will still see the same behavior; the number of entities that move into the Server for processing will be the number of Workers that were available to be seized. Happy Modeling! Liz -
greetings everyone, Currently I am working on a simulation for my research and I am considering different staff schedules I would like to be able to have overlapping schedules for my workers and would like to be able to change the number of workers working in different time periods. for example, I would like to add 2 extra workers in busy period. is there a built in Simio feature that can help. Thank you very much

Hi all, I am modeling a restaurant, where orders are placed until 22:00. The preparation of these orders takes approximately 20 minutes (it can be more or less due to the probability distributions involved). I have some workers whose schedules are from 10:00 to 22:30 and they prepare these orders. The problem is the following. Suppose that it's 22:30 and there are still some orders in the queue. Since the worker's schedule ends now, those orders can't be processed and will remain for the next day. This obviously does not happen in a real-life restaurant. So if at the end of the worker schedule (22:30) there are some orders in queue, I would like to extend the schedule until all orders are met. How can this be done? Thank you in advance, Marcel Favereau

[EDIT] Hi all, I am modeling a restaurant, where orders are placed until 22:00.

So if at the end of the worker schedule (22:30) there are some orders in queue, I would like to extend the schedule until all orders are met. The problem is I don't know how long it will take the workers to prepare the missing orders, so I can't suppose a certain time needed to complete the orders. I have to wait that the last order is prepared to set the end of the working day. How can this be done? Thank you in advance, Marcel Favereau

I have multiple workers for different tasks and I want the workers to work according to different work schedules. When I use the work schedule option, all workers of one process use the same work schedule. In the examples they use different workers for each shift, but since workers come and go at different time during the day this would require a lot of different workers for each process.. For a server the capacity of the server can be changed during the simulation, is there a way to do the same for the amount of workers in the system? Or let each worker work according to their own custom work schedule imported from a table?

I got a file where each worker has a unique ID for every time they work, and a start and end time of their shift. I also converted to to time intervals and the amount of workers that are working at that particular time interval. I tried using the table based schedule for both tables, but this does not seem to work since all workers get the same start and end time.. Your method requires many different workers for the same process, each with their specific work schedule which looks like a lot of work for something that looks quite simple... Is there no easier way to do this ? Thanks for the quick reply!

I'm trying to model airport ground operations using workers for the different processes, servers for the gates, entities for arriving airplanes and TransferNodes to control the flow of entities and workers. My research is focused on the control of these ground processes, but I can't get my process logic correct.. I attached a simple model to help answering the question. I want the workers to move to the right server before the entity arrives there and can immediately start processing the entities. One method is to use a global queue from which workers decide which entity to process next based on some criteria and dynamic rule selection. In the attached model I use two entities which go to Gate1 and Gate2. Gate 1 needs workers move to the node before it can start processing, Gate 2 does not. Using an add-on process, I move the worker to the gate before it is requested and wait for the entity to arrive. But for some reason it does not start processing immediately when the entity arrives and I can't figure out how to model this correctly.. It's the first time I'm using Simio, so I some help would be appreciated on how to set up the logic for my processes.. I'm kinda stuck now on how to get some basics thing in my model right or if I'm using the right processes steps.. Thanks in advance! TestModelWorkers.spfx

A worker may be assigned a work schedule similar to that of a server or vehicle. I would just leverage the default logic by throwing the worker into an Off shift State. There are numerous options as to how assign a work schedule. From your problem description, a Table Based Schedule may be more optimally suited.

I've got multiple workers going to single server. As the title implies, I'd like these workers to mimic the real-life behaviour of randomly going on leave for a random amount of time. Ideally I'm looking for something that's shown in vehicles or servers, but for workers. Does anyone here know an easy workaround for this? I did think about adding in a add-on process after the worker releases an entity with a counter, and after a certain count the worker is seized for a random amount of time. I just thought there would be a better way. Another alternative would be creating a work schedule for each worker, but there's over 60, so that might take a while.

How I can define a state variable only for the workers. For example if I want to check whether the worker had his lunch break or not. I am creating a dummy entity as lunch and it will call workers based on some schedule. I want to make sure the entity calls some worker which did not have lunch yet. How can I do that? The lunch entity will seize a worker from a list, however there should be a condition that makes sure the worker did not had lunch before. Note that I do not want to model this my setting the lunch hour in the off-shift period. The worker should be on shift and a lunch entity will seize the worker for one hour. There are 5 workers. 3 of them will have lunch from 12 to 1 and 2 of them from 1 to 2. I am creating 3 entities at 12 and 2 at 1. They should seize the workers and make sure they did not have not been seized for lunch before.

Share a Resource based on Time Schedule
rthiesing replied to bragadesh's topic in SI General Discussions
This might not meet your needs exactly but hopefully it can provide some ideas that can help you move forward. You can use the Work Schedules in Simio and the Value column in these schedules, to dictate which Server the worker should go to during that hour. This example also uses the Evaluate Seize Attempt process on the Worker so that the Worker rejects all of the jobs that are not at the appropriate Server. If you wanted to Subclass the Server, you could add a Property to it and then check to see if the current Schedule Value matches the property on the Server, instead of using the Server names, like this example does.

Worker can only be on or off shift, so no. But for very similar behavior, you can have one Worker of population 4 that follows the indicated schedule and a second Worker of population 4 that works from 8-1. I expect you could handle this with some tricky process logic - perhaps someone with more time can help you with that.

Hi All, I have a question regarding a maintenance workshop that consist of 11 workers who are used as resources for 4 servers. The worker keeps on working while he is off shift. I tried the simbits; Worker Uses Work Schedule Interrupt Working Off Shift and Resource States When Off Shift. These work with one worker. However, i get the following error when I try to add more workers. Entity: Defaultentity.94 A runtime error was detected at time 11,0 hours at the following process step: Object: Model Process: Resourceoffshift1 Token: Mytoken1.46 Step: [Release] Release1 Property: ResourceReleases.NumberOfObjects Error releasing resources of type specific 'Worker1[1]' owned by object 'Defaultentity.94'. Unable to release '1' object(s) of the resource type because the number of individual resources owned and satisfying the specified release criteria is only '0'. Does anyone know how I can get my workers to stop working while they are of shift? I've added my model to this post. Thanks!! Roeland van Rijssel modelmaintworkshop.spfx -
More resource, server capacity should double
dsturrock replied to FOUADELALBI's topic in SI General Discussions
In server 1 you have indicated that you have 2 workers available and you need both of them available for the 2 minute processing time. In server 2 you have indicated that you have 1 worker available and you want it available for the 2 minute processing time. You would expect statistically identical throughput. Perhaps what you meant is that when you have two workers available that work would proceed in half the time. If so, the processing time should be indicated as 1. Or perhaps you don't even need the workers -- if you just change the server capacity via a schedule you will see the throughput automatically change accordingly.
