Quantum XL Monte Carlo Features¶
Build a model of a measurement or a product, describe each input by a distribution rather than a single number, run the simulation, and read what the spread of the inputs does to the outputs.
The commands are on the QXL Monte Carlo ribbon tab, in three groups: Design for building and marking the model, Monte Carlo for running and analysing it, and Additional Tools for the worksheet tools that sit beside it.
Model Building¶
QXL Monte Carlo > Design. Marking the cells, then building or importing the design sheet.
- Model Building Overview - Every page in this group
- Mark Input - Give a cell a distribution so the simulation samples it
- Mark Output - Mark a cell as a result, so every trial's value is collected
- Correlations - Say which marked inputs move together, and by which copula family
- Unmark - Take the marking off a cell
- Custom Distributions - Build a distribution of your own shape and pick it when marking an input
- Create Empirical - Use a column of your own sample data as an input distribution
- Create Monte Carlo Design Sheet - Write the sheet that holds the model
- Modify Monte Carlo Design Sheet - Change a design sheet already written
- Import Model from Quantum XL DOE - Build the sheet from a DOE regression model
- Validate Model - Check whether the model runs in the fast engine, and if not, why
- Copy and Paste Markings - Move markings between cells, sheets and workbooks
- Supported Distributions - Every distribution a marked input may use
- Supported Excel Functions - Every Excel function the fast engine can parse
Analyzing the Model¶
QXL Monte Carlo > Monte Carlo. Running the simulation and reading the result.
- Analyzing the Model Overview - Every page in this group
- Run Model - Run the simulation, at a chosen count, in either engine
- Optimize - Search for the input settings that give the best result
- Percent Contribution - How much of each output's spread comes from each input
- Latitude Plot - Chart where each pair of inputs keeps the outputs in specification
- Surface and Contour Plot - Plot an output over two inputs swept across their range
- Tolerance Allocation - Sweep each input's spread and report what it does to the outputs
Additional Tools¶
QXL Monte Carlo > Additional Tools, and the worksheet tools that go with them.
- Additional Tools Overview - Every page in this group
- Sampling Matrices - Write a worksheet of sampled factor settings, one column per factor and one row per run
- Scorecard - Create a scorecard, and chart the one you have
- Linear Tolerancing - The three linear tolerance stack-up worksheet templates
Latitude Plots, the tutorial¶
- Latitude Plots Tutorial: a worked example, from a two-part tolerance stack to a plot you can read, with the arithmetic to check the simulation against. Separate from the Latitude Plot tool page above, which covers every control.
