I'm looking for some pointers or example models for an Energy Usage model. I have a client (mining company) that specifically want to model and plan their...
Hi got a question regarding CB Predictor and confidence intervals. Can somebody tell me what the computation (formulae) behind it ? Regards Rado Lavrih...
Rado, Information about the algorithm used to compute the confidence interval in CB Predictor 1.6 (which is a part of Crystal Ball 7.0, 7.0.1, 7.1, and 7.1.1)...
I am working on a project dealing with a distalation process where the feed rate and composition changes to the tower. The feed rate is changed by operations...
Robert, Sounds to me like the key would be to get an understanding of what the expected rate of change, and the uncertainty in it. Historical data may be a ...

Hi All, I have a bit of a dilemma. I recently inherited a rather large (12mb) and complex model. It currently takes 9hrs to run. I have been asked to...
I would like to completely remove Real Options Analysis Toolkit V 1.0 from my system, including all registry entries. Does anyone know of a way to accomplish...
Tyler, Yes, there are many things you can do to speed up models. Many times you will find that the original model has had many bells and whistles added to it...
Hi, ... I am working with a complex, time consuming simulation model, too. One thing you should do in order to improve the simulation speed, is to check...
Thanks everyone. Taking much of your advice I have modified my model and now enjoy a 4X increase in speed even with a substantial increase in the number of...
I am a system administrator for some users who are just starting using Crystal Ball 7.0. We are attempting to save the results of simulations, but we are ...
Jeremy, The Product Development team at Decisioneering is aware of this issue and we are working on an ability to save results more efficiently in a future ...
Not sure if this will be relevant but - -I ran into similar problems that were cleared up by switching to winXP/Office XP; Turns out that regardless of how...
Hello, I have a model with about 600 forecasts. I want to extract a subset of the forecasts for analysis on separate tabs. It became very tedious to extract...
Julie, First of all, I would like to find out from you which version of Crystal Ball you are using. I will assume that you are using either version 7.1 or ...
Thanks, David. I already had that command at the start of my code, and it didn't seem to matter. Just as an FYI, I ended up creating VB code that loops through...
Hi All, I have read manuals of Crystal Ball and OptQuest for two weeks. You can see I am new here. I would like to receive your help. I have two decision...
I have a financial model that i constructed with CB v5 that ran simulations from a macro that i have built. I have since upgraded to CB v7 and my code no...
I got CB recently and am still learning what it can do, and was wondering if more experienced users can help me with the following optQuest modeling: I am...
Macros are handled differently in CB 7 than they were in CB 5. There is no longer a Macros tab in CB 7. Instead, user defined macro must be defined in the...
