WITNESS Scenario Manager

WITNESS | Overview | Optimizer | Scenario Manager | VR

A module included as standard with both the manufacturing performance edition and the service and process performance edition of WITNESS.

It offers a highly flexible framework for experimentation and analysis including:

Choice of Model, run length, number of replications
Specification of model parameters for experimentation
- Ranges - with step value
- Sets of values
Parameter Groups for linked input values
Full factorial simulation runs with progress indicators
Comprehensive statistics generated automatically for each model run
- Separate tables for each WITNESS element type
- Tables can be sorted, filtered and grouped with multi level hierarchy
- Summary statistics can be added - including confidence intervals
- Optional output of statistics to Excel
- Optional definition of key performance indicators - auto tables and graphs of these.
Flexible charting
- Select the data and chart it!!
- Full component menus to set fonts, colors, lines, legends, etc
- 20 different chart types
Wizards to help
- Charting Wizard
- Parameter Group Wizard
- Scenario Setup Wizard from WITNESS menu
Professional SQL Server database repository
- Stores details of all experiments
- Stores model name, parameter settings, run lengths
- Stores all charts created including custom formatting
- Provided with an easy backup/restore utility
- Stand-alone or shared database across network
Option to add non simulation parameters such as investment level
Compare different experiments on different models with aliasing to align statistics for comparison and charting.

The WITNESS Scenario Manager is packed with novel and exciting options all helping to obtain and make sense of your simulation results. Getting information out is easy too with many options including full WYSIWYG charts into Word or Powerpoint, etc.

Scenario Manager Screenshots and Viewlet Gallery

A typical customized chart showing a key statistic from 4 different simulation runs - each with clear scenario labels, adjusted colors and title.

A typical radar chart showing the variance of different replications of the same experiment with legend.

A view of the investigation browser and scenario definition screen. The browser shows the hierarchical structure of investigations and scenarios. The scenario definition screen shows the setting of experimental options and the selection of key performance indicators.

Parameters are easily selected from the model browser view and dragged into the table where values can be set.

A section of a results table showing a table where different groupings have been applied in order to generate confidence interval statistic for scenario 1.

An activity status chart for 40 different simulation runs for the selected activity.

A screenshot showing a whole scenario manager screen with an assortment of customized charts.

A variance chart for 20 replications.

An automatically created line chart showing key performance indicator results across ten scenarios. Each graph shows the optional toolbar display giving access to formatting options.

Reduces risk in Decision Making

Accurately predicting how proposed changes to a facility or process will work.

Supports Investment Decisions

Provides evidence to identify profitable ideas and avoid costly mistakes.

Eliminates Waste and Error

Showing which control methods and which resource profiles are most efficient.

Communicates the optimal solution to decision makers

Enables scenarios to be compared and the best option for the business to be graphically reported.

Easy to use

One training course will provide you with the skills needed to build simulation models and get results - quickly!

Simulation is a decision making tool. If you have a process in your organisation that you would like to optimize or improve, simulation can provide a cost effective means of finding the right solution, without relying on gut instincts or hindsight.
