TWS/WebAdmin for z/OSCritical Path Simulation


TWS/WebAdmin for z/OS Simulation

• Temporarily change, insert or delete dependencies and jobs in TWS/WebAdmin’s tables

• Perform (mass) changes to the estimated durations• Save simulation scenarios for later reuse • Calculate the total duration of the critical path of all selected

jobs• Shows the jobs on the critical path

- In a list (table) - As netplan (flowchart)- As barchart

Version 2.2 of TWS/WebAdmin for z/OS provides forecast and Version 2.2 of TWS/WebAdmin for z/OS provides forecast and critical path runtime simulation. This presentation shows critical path runtime simulation. This presentation shows examples of the basic functions: examples of the basic functions:



You can start Simulation from AD Modify or Query part

Specify search criteria and click

Simulation



Enter a name and description to save

your simulation scenario (selection and modifications)



You can load and reuse your saved simulation

scenarios later



General information about the simulation

(not jet started)The selected applications

and jobs

Click Simulate to start the calculation of planned start times and the critical path



Enter a default start time and check if time dependencies

should be taken into account or not (input arrivals are

always considered to build the external dependencies)



The critical path has been

calculated (45:02 min)

Operations on the critical path

are marked



If you scroll right, you can see estimated planned start and end times,

which are calculated, based on the dependencies and estimated durations



You can define one or more change rules, e.g. add/subtract a percentage

or set a specific duration.

Here we add 10 percent to the duration of operations on

WS=WAIT of applications TCP*

Here we add 10 percent to the duration of operations on

WS=WAIT of applications TCP*



The higher durations result in a longer critical path

(49:32 min)

The new “computed simulation durations”



In the Netplan, the operations on the critical

path are marked red

Maybe some dependencies

should be changed.

You can insert, delete, modify applications and operations just for simulation



Click on Modify and you can change “everything” of an application



e.g. change or add external predecessor by using the

application/operation picker



The changed application will be stored in TWS/WebAdmin’s

internal database with state “simulation”. You can keep that simulation version as long as you want and optionally you can take it over into TWS.



The recalculated critical path is shorter now (38:32 min), even if the durations are still increased



You can see which applications has been changed for simulation

and which are unchanged (actual)



In the new netplan, the operations of changed

applications are marked green and the new critical

path is marked red (the blue one’s are identical to

the current version in TWS)



If there are time depending jobs, the calculation routine can

optionally take care about it. The critical path may get longer (here

01:41:01 now)



You can see which operations are time dependent and it’s start times



The new critical path

Double click shows the details



There is also a useful bar chart with timeline etc.

Operations on the critical path are marked red



Applications are maybe scheduled in different run cycles on different days.Enter a date and you will get only that applications,

scheduled on that day (e.g. Thursday)



Some more jobs are scheduled on that day

(e.g. Friday)



And that results in a different critical path



Simulation works also with lots of jobs and

dependencies



You can zoom in the netplan and follow the

marked critical jobs



There is also a netplan and a list of the critical

jobs only



• Calculate the critical path of selected applications, scheduled for any Calculate the critical path of selected applications, scheduled for any day in the futureday in the future

• Try “what if” scenarios likeTry “what if” scenarios like - What if some dependencies are changed - What if new operations are inserted- What if all jobs A* are running 20 percent longer- …

• Verify the critical path - In a list - In a netplan (flowchart)- In a bar chart

• Planned enhancements: Take the durations - of a past run day - from another input file - …
