Product Name: WITNESS VISIO Simulation Solution
Product Description
The WITNESS VISIO Simulation Solution is the perfect way to
test the performance of a process before implementation. It adds the power of
simulation on top of traditional process mapping. The simulation model is taken
from the process diagram and 'runs' the process virtually. It takes account of
the variability of the process and reports accurately on how this variation
affects key performance indicators in a way that spreadsheet analysis can never
do. With accurate results like these it is possible to make much better informed
decisions on the structure and the implementation for the process.
Because the WITNESS VISIO Simulation Solution is based on
drawing diagrams in VISIO it is easy to pick up and use. Even if you have never
used simulation before it is a simple process to create your own process
diagrams and then add the data behind each process box to drive the simulation.
The WITNESS VISIO Simulation Solution provides ready made
stencils to use inside VISIO. These reflect the latest in standards for creating
process diagrams - there is a choice of IDEF3, Process Chart and BPMN (Business
Process Modeling Notation). These standards ensure some rigor in the modelling
process and offer a flexible way to store and use the data for any process. One
further stencil provides the option to define extra items for a simulation such
as shift patterns - enabling extra data to be defined and used.

Processing Model data can include some or all of the following:
|
|
- Entity arrival profiles or distributions
- Entity Attribute definition and use
- Activity timings and timing distributions
- Entity Revenue and initial costs
- Activity costing by time / operation
- Activity input and output queue constraints
- Activity Concurrent Process Limit option
- Choice of process type - single, batch, split and join
- Resource allocation to activities including AND/OR rules
- Shift definition with hierarchy for easy definition
- Resource shift allocation
|
- Shift overrun allowances and penalties by process
- Resource costing by time/operation
- Hierarchy using different VISIO sheets/pages
- Results allowing goal definitions and designation as
significant/non-significant
- Delay queues with distributional delays - either minimum or
maximum or both possible
- Delay queue capacities
- Flexible routing with easy choice options - probability, entity
type, time in model, attribute based, percentage - one or more
ways.
- Matching join together junctions to match previously split
documents/other
- Icon Choice in model
- Iterated activities
- And More....
|
Within Minutes a new process diagram can be revealing its true performance.
Using the special WITNESS Viewer the model is opened and run. The visual
nature of the simulation display shows process flows - this helps to detect
any major omissions in the flows defined. Results build up in tables and
charts and show statistics indicating key capabilities - throughputs,
utilizations, service times, etc.
|
Results include:
|
|
- Entity Throughputs
- Entity Times in System
- Work in Progress averages
- Throughput by time unit
- Output Count at all exits
- Average Queue Sizes
- Maximum Queue Sizes
- Average Delays in Queues
- Resource Utilizations
- Resource times on each task
- Resource number of tasks
|
- Resource Average Job Times
- Service levels against goals
- Six Sigma Scores for process times
- Profitability Analysis
- Cost Category Analysis
- And many more....
|
All results can be output to Excel for further analysis. An additional
option is the Optimization of the process using WITNESS optimizer.
