Hello Admin Thanks for your suggestion. I tried to build my model according to your suggestion. But I failed to authenticate whether I am going right way to not. If you have time, could you please see the attached model and do some comment relating to my modelling problem. Thanks Have a look at the ...

Thanks for your explanation. Do you have any idea, how we can get the information of subscript value? say, one firm is medium but doing good business, another is also medium but not doing good business. how can we differentiate them to put the value? Moreover, what could be the maximum value of a mu...

please!


thanks

Hi Tom We have purchased 5.11 first then updated in to 6.0. Yesterday, I have successfully updated into 6.0A. I am very much sure that my version has this option of subscript. The version number doesn't distinguish the type of Vensim you're using. There's a PLE 6.0a, DSS 6.0a, etc. The functionality...

Thanks for your reply. I want to use data for two of the following reason and data is in excel format. I can convert other format if it is easy! 1. I want to use data for creating look up which will be input of a variable or output of a variable. such as last 52 weeks production, sales, demand, supp...

Dear Admin As you referred me to read a link regarding data using in vensim was not understandable to me. Is it possible to get some link where "step by step" process has been written regarding get data from other sources in Vensim? Secondly, I have purchased vensim professional. I am wond...

Hi! Could anyone suggest me appropriate formula? What I am trying to do is, will buy 100 cows from market and grown them up till getting milk (say, 50 weeks). then do milking for another 50 weeks. in between this process I will buy another 50 cow which will give me milk after 50 weeks. then first ba...

Hi Tom Thanks. In this case, do you mean that 1=week? is it right? as you suggest me to practice data variable. could you please refer a simple data variable model where you called data from excel or some other places to run a model? please define how to use or locate input/output or X/Y variable if...

thanks. I understand your attached model but I have few questions in my mind. I have seen some model that they did not use any time variable. is it possible to continue the same purpose without giving input of time variable? My second question, if I use "time to adjust" variable unit as &q...

Hi! I need further understanding of time lookup and other variable related look up. I have attached a model where I have tried to use time look up. Could you please confirm and assure me whether this kind of lookup can be used in modelling? My second question is that how can I develop a lookup where...

Thanks and it will help me to understand few important things. Qs: 1. why do not you use rate variable or bulb as you used auxiliary? Is there any particular reason behind it? I was trying to do this quickly. Q2. How can I add capacity and target variable? I want to set a target production which mig...

Thanks for your time to revised the model. I am really sorry to have so many question in my mind as a learner. I have three question in my mind which I have asked in the attached model. These questions are related to "using rate variable instead of auxiliary", "capacity and target var...

Farm in rate measure how many chicks enter into ultimate broiler farmer as chicks and these chicks will grown up as chicken later.

Administrator wrote:ok, start with "FARM IN RATE". What is this, and what is it measured in?

Thanks. I have gone through your documents which I have already read it but confusion is still same, why don't we use different time step in same model? by the way, here I am sending revised model having problem with conversion. As par your guidance, I did solve some of my problems but when three di...

Dear Tom Hi! Thanks for your last explanation of unit conversion. Now I have little confusion about timestep. Say, I need 21 days to hatch a egg that means if I use time step 1, it will require 3 time step, isn't it? You have sent me a model before where you put TIMESTEP between two Levels. My quest...

Thanks so much. Now I understand where was my problem? thanks again A few notes, Remember that stocks are "usually" measured in "eggs", "chicks", "widgets" etc. The rates that flow in/out should be "eggs/week", "chicks/week", "widgets/...

Dear Sir I have tried to convert the unit chicks into eggs but failed to do so. Here, I have attached a small model where I wanted to convert chicks to eggs but its giving me RHS errors. Would you mind to show the correct code in my model? appreciate your help. thanks To convert from egg to chick, c...

Dear Concern I am really apprentice in Vensim and trying to cope up with it having minimum mathematical knowledge. I am trying to do a process model on poultry industry to reflect real life things. In addition, I am trying to add inventory, demand, supply and capacity issues as well. I have attached...

Is it logical to put two valve rate in one pipe? how it works?

I tried to put multiple valve rate in one pipe but I can not able to stick second one on the pipe? what is the command for doing this?

will be thankful if anyone answer me.

Thanks. I will try accordingly.

Could you please help me to find out "BEER GAME MODEl" in Vensim version? Where can I find it?

There should have a suggestive window after simulation run relating to wrong usage of unit name. If there will be some suggestive comment relating to model, it would be helpful for the modeller to fix their model

Dear Concern Thanks for your link. Still I have doubt and I failed to apply in my model. I am working on poultry supply chain modelling. Briefly, initially "eggs" enter the system then convert it to "chicks" then convert into "chicken". after that chicken produces wasta...

Dear Concern Hi! I am totally apprentice of this software. Can anybody describe with example that how unit can be convert to other name? such as "kg" to "tonnes", "chicken" to "KG". What is the precondition to convert units based on certain variable. waiting f...
