Description |
2.1 |
QtsCommon.xla |
Fixed worksheet protection error when
running in Excel XP |
Mva.xls |
Fixed computational error in calculating
Lq for each node |
|
M_Ek_1.xls |
For k>25, removed old Wq(t) plot data
from PlotData worksheet |
|
M_M_1_balk.xls |
Corrected error in calculating pmf and CDF
for number of customers and removed an erroneous balking function definition. |
|
G_M_1.xls |
Added version of H/M/1 model with general mixed exponentials for inter-arrival time. |
|
G_M_c.xls |
Added version of H/M/c model with general
mixed exponentials for inter-arrival time. |
|
G_G_c_bounds.xls |
Corrected computational error in
calculating Wq lower bound. |
|
2.0 |
SingleNodeSim.xls |
New simulation model added to the package. |
Jackson.xls |
Changed default value in routing matrix
from "?" to 0. |
|
Buzen.xls |
Changed default value in routing matrix
from "?" to 0. |
|
Jackson_2Classes.xls |
Changed default value in routing matrix
from "?" to 0. |
|
Mva.xls |
Changed default value in routing matrix
from "?" to 0. |
|
QtsPlus.xls |
Modified index build to eliminate
duplicate entries; this allows same model to appear in multiple sections. |
|
G_G_1Sim.xls |
Changed default behaviour from
"Enter" key to "Tab" key when specifying inter-arrival or
service time distributions. |
|
G_G_cSim.xls |
Changed default behaviour from
"Enter" key to "Tab" key when specifying inter-arrival or
service time distributions. |
|
1.0d |
M_M_cSeries.xls |
Fixed numeric overflow error when c >
170 |
M_M_c.xls |
Fixed numeric overflow error when c >
170 |
|
1.0c |
M_Ek_1.xls |
Eliminated restriction on k<=25 for
M/E(k)/1 model. Wq(t) chart not
produced if k>25. |
G_M_1.xls |
Added computations for arrival-time
steady-state probabilities and arrival-time L and Lq, converted to iterative
root finding algorithm (no longer dependent on Excel Solver) |
|
G_M_c.xls |
Fixed error in computing Wq(t), added
computations for arrival-time steady-state probabilities and arrival time L
and Lq, converted to iterative root finding (no longer dependent on Excel
Solver); added check to ensure K>=c to prevent out of range subscript
error |
|
QtsCommon.xla |
Added iterative root finding procedure in
support of the changes in the G/M/1 and G/M/c models |
|
1.0b |
M_M_c.xls |
Fixed: M/M/c not displaying updated size
probabilities when parameter 'c' is changed. |
1.0a |
Buzen.xls |
Fixed:
Buzen not reporting performance measures for Node 4 of queueing
networks of 4 or more nodes. |
1.0 |
