Hello, I am trying to model a situation when a truck which comes for unloading and requires a worker or combination for worker to do the task. Basically I want to know how can I engage secondary resource (Worker or forklift) for loading, unloading or even for transit ( transit I require for cranes ). I am a novice in Simio and will be thankful for any kind of help.

Hello - At the moment, my university group and I, are having troubles on simulating a basic telephone queue in SIMIO 10. We're in doubt on how to adjust each object, so that they can run on specific data we have received from a given source. And more likely on how to set this up? In the uploaded picture below, our basic model is shown. So please, if you have any advice on how to adjust this specific model to run as a basic telephone queue write a comment. All help is appreciated Best regards.

I was inspired by the VehicleX3 (vehicle with operator) that was shared on this forum. I would like to use this type of VehicleX3 with an operator who is a worker to simulate a process where the operator is required to take breaks after certain periods of activity. To implement this logic, I think it would be helpful to have Reliability Logic for the worker object in Simio. This doesn't seem to be part of the standard library so I tried to create my own subclass version of Worker with the Reliability Logic "copied" from the Resource object. My attempt to implement this custom object seems to work as long as the custom worker object doesn't "move". If the custom worker object moves, I get the Runtime error "Possible infinite loop detected in process logic". Any assistance in getting the logic working properly, or pointing me to an existing custom worker object that has Reliability Logic incorporated would be greatly appreciated. I'm attaching my small example model to illustrate the error when the worker (P1) is required to move to the Dest1 server as a required secondary resource for processing.

I have a source, called forklift source, that has a varying interarrival time based on the time of day. To do this, I created a time indexed table with the different interarrival times in different rows and the interval period set to one hour. This source also depends on the interarrival time of another source called Newtrucksource, but not on an hourly basis. I am trying to conduct an experiment where the interarrival time of newtrucksource changes with different experiments and a different time indexed interarrival table for source 1 is used for each of these different interarrival times. To do this, I created a real property for newtrucksource's interarrival time and a table property for forkliftsource's time indexed interarrival table. However, I can't get this to work because in the model, the interarrival time property for the forkliftsource must be a "number" and I am referencing a table which comes up as using "string". Trying to find a way to make this work.

People often want to model two or more vehicles or entities moving together. There are a few components to this: 1) Seizing the resource appropriately - can be done in processes, but often best done within the vehicle object to make the modeling easier. Here, a vehicle has 4 properties added to support use of an operator. 2) Animating them moving together - the picture below shows use of a second queue animated on the custom vehicle. 3) In some cases, you also need the "driver" to be shown moving. The Attached Animation Speed illustrated below, accomplishes that. I have attached a model that uses a custom vehicle object to model a wheelchair which is "driven" (pushed) by a person to pick up a patient. *********** FOR VERSION 190 AND EARLIER ************************************* VehicleWithDriver.spfx You could use the same approch, possibly with just animation changes, to model something like a truck or forklift that requires a driver. In fact, I just added a second model to that same project that illustrates use in manufacturing (e.g. a lift truck and driver).VehicleWithDriver.spfx VehicleWithDriver.spfx *********************************************************************************** ************** FOR VERSION 191 AND LATER *********************************** VehicleX3.spfx VehicleWithDriver_VehicleX3_Examples.spfx For more information on the update, see the post below. ***********************************************************************************

Hi, currently I am doing my internship at a logistics company. I am simulating the warehouse process, but due to the limitation in the number of symbols I have split the process in an inbound model and an outbound model. Now I came across a problem. There is a X number of employees which both work in the inbound and outbound model. Is there a way that both models can make use of one workers list? Or another way to solve this problem. Kind regards

Hi Everyone, I have 100s of different products in a warehouse and I want to get statistics for all of them such as distance travelled, number entered and exited. So I created the entity instances for each product automatically through data table. The entity.totaldistancetraveled function doesnt increase since the entity doesnt moveby itself but moved by forklift instead. So I have created a state variable called "distanceonforklift" and increased by the difference between the forklift total distance travelled value when entity exits and enters to forklift. I have also created a function called "distancefunction" on the entity and equated it to "distanceonforklift" state variable of the entity. For the return type of function I have chosen "number" and set the unit to "length". I validated that both distance state variable and function is calculated correctly in the facility window. However I cannot output the result of this state variable on the model results screen. I used the following expression under model outputstatistic but it didnt work. "ProductA.DistanceFunction". That expression gives me 0 value although there are some entities of this product which enters and exits the system. How can I see the average total distance travelled on forklift for the whole population of Product A?

Hello everyone, I have a simple production line of 15 servers, some combiners, nothing too complicated. I need to somehow setup the input buffer at each server to have 1 entity at the start of the simulation and then run it. Or having filled servers with 1 entity at each server. Could anyone please help me and show me how to set it up? I need to start counting the stats once all the workstations are filled, but warmup period does not seem to work for that case, because it destroys the enitities at the servers and starts over. The filled-input-buffer-way looked to me like the easiest solution. But if there is another way, please let me know. Thank you!

Hi, I have a bottleneck at the end of my assembly line. I cannot dupplicate that station as my total number of workers is already high. Before hiring, I would like to try and reallocate and have satellite employees. I want to allocate my workers to that station when the input buffer has exceeded one entity. Every worker has to finish the entity they are presently working on at the other stations and the first workers that are done need to go the bottleneck station. The rest of the time, the workers can be allocated based on the smallest distance to the work stations. The bottleneck station usually requests 4 workers. That information is already set up in a table. When there is two entities in queue in that buffer, I want workers to be able to go finish the work and hence increase the processing time by X. I have tried a lot of different things, and all my data is stored in relational tables. Thanks!

Hi, Zan! Many thanks for this. Just tried it and it seems to work just fine. I just have to work out what you did to set it up - but that's for me to do now. Steep learning curve, especially when we have short deadlines!

Hello, a similar question from 2015 was not answered http://www.simio.com/forums/viewtopic.php?f=6&t=1936&p=6252&hilit=selection+condition#p6252. I have the same problem. I want to use a rather complex selection condition, but they don't work. For example: ((Server1.AttributeA == 1) == (Server2.AttributeB == 2)) or Math.If((Candidate.Node.AssociatedObject.Is.TypeA),something) I checked my conditions extensively and they should work, but they dont. It seems only "simple" selection onditions work. Does anyone know something about that?

I am trying to run an experiment for 7 days (with 2 day warm-up) and I was hoping to find out what impact Work Schedules have on this. So I have 8 hour shifts scheduled with various resources scheduled to go off shift at times specified in the work schedule. When running an experiment for 7 days, does SIMIO run during the off-shift period as well because my experiments seem to be extremely slow i.e. if my day shift is 9 am - 5 pm, does the experiment carry on working from 5 pm even though there is no activity at night and start again at 9 am on the Tuesday and so on till the end of the seven days? I now this may be a trivial question and would appreciate any help with this.

Leaving it as is should work for your purposes?

Dear Forum, I am trying to build reality into my model. I have 3 shifts (1st, 2nd, 3rd). 1st Shift works form 7AM-3PM, 2nd Shift works from 3PM to 11PM, then 3rd shift works from 11PM to 7AM of the following day. So, I tried to put in Day Patterns in my schedules and on my 3rd shift, it resulted in an error "Duration must not result in a Work Period that spans multiple days." Is there a way to model these 3 shifts as they actually exist in the factory or do I need to change the time frames to "dummy" time frames so that do not span over a 24 hour period? Thanks, Bill Industrial Enginer

I am making a model that simulates trucks coming in with a certain amount of pallets. These pallets are transported with the use of forklifts to a sink. The truck arrives at a seperator where the pallets and trucks are seperated. The idea is that multiple forklifts work on one truck when there is only one. But when a second truck arrives one forklift should switch to the new truck. In the current model they work on the same trucks and react when a new truck comes in they unload it but then continue transporting the pallets of the first truck instead of staying with the new truck. So as soon as a forklift unloads a truck I also want it to transport the pallets within it. I think this has to do with the reservation of the vehicle. I already tried a lot of different options but nothing seemed to be working. I uploaded my model as well and I really hope someone could help me with this issue. Thanks in advance! Model1.spfx

I am trying to model forklifts moving around that require a worker to operate. I found this example under SI Shared items and have tried to recreate as best I can. However, my model is complex in that I have multiple workers and forklifts. I want the forklift to choose an available worker. I can get it to work with 1 specific worker, but when I choose from list of operators I get this error: I have tried all the different Travel Mode options. Any ideas on how to correct this?

Hello, a Server block has a property named "Off Shift Rule" This is normally set to "Suspend Processing", i.e. the server signs off at the end of the shift and abandons all the waiting work. If you want to finish the waiting work, choose the other option, "Finish Work Already Started" I suppose that's what you want.

Hi! I have been using SIMIO for quite some time now, but I have barely come across this need. I need to record the time spent per entity at any given path/server in the simulation, rather than obtaining the average time for all entities at the end of the simulation. Take the image below as an example. I need to record the time spent in the link (TimeOnLink) per entity generated. The path corresponds to that connecting the source to servers 2-7. Then, I need to record the time spent per entity on servers 2-7 (TimeInStation). I can display the unique ID number for each entity by Entity.ID, now I need to match the statistics. I figure the best way to model is trough ExcelWrite, but I can't manage to make it work. Any hints? The plan is to get the following information per entity, rather than a summary of all entities.
