Computes (via Monte Carlo) the fraction defective in table
manufacturing. |

|
| μ, σ |
(cm) |
Mean and st-dev of leg (item) lengths. |
| a, b |
(a ≥ b ⇒ no trunc.)
|
Truncation a (min) and b (max). • |
| δ |
|
Max. inter-difference. • |
| N, .seed |
|
No. of items ("lot size"), random no. gener. seed. • |
| tolG, klass, ymax |
['0' (¬ '.0'): auto.] |
Tolerance, no. of histo. classes,
max. y for graph. • |
| Show values |
|
Shows the coordinates of the graph. • |
Simulates,
via Monte Carlo, the lengths of (four) table legs, which follow a (common)
truncated Gaussian distribution —or non-truncated
iff ¬(a < b). A defective set corresponds
to an "inter-difference" greater than δ ('tol diff' in the
results) between opposite legs.
Plots pdf and cdf of table behaviour.
(The parameter 'tolG' is for the inversion of the
Gaussian distribution.) The computing time for 500 000 items is
about 8 s. Above ~30 s, execution may be halted (on the Internet). |
