Simcad Pro Process Simulator
Discrete--Event based process simulator with extended continuous simulation capabilities
Currently includes Dynamic VNM/VSM
Will integrate with PFAST
Currently used by many companies, including
Jostens, Baxter, USAF, Bechtel SAIC, The US Department of Energy, Rumble Automation, LaSalle Department of Energy, Rumble Automation, LaSalle Bank, Florida hospital and many others
What is Lean?
Why Lean?
Benefits of lean
Improve efficiency
Decrease and control lead time
Remove waste
Increase on-time time delivery
Reduce WIP
Happier customers, better work environment, less stress, reduce production cost.
Lean Approach
Lean initiative is a constant improvement cycle
Build a value stream map and process flow
Goal is to analyze the operation
Identify waste
Prioritize improvement project (Kaizen)
Analyze improvement impact
Complete the Kaizen(s)
Prioritize the next Kaizen(s)
The Value Stream Map
Process flow
Displays flow characteristics
Process constraints and performance
Timeline - Helps identify total waste time
Help in identifying the critical path
Good documentation tool
Issues with VSM
Has a tendency to grow too large
Many value streams span multiple walls
Contains static data
How does the value stream change when the process changes
Impact on the rest of the value stream (Up stream and down stream)
Good for static environment, but can be challenging otherwise. (the Toyota model)
Simplifying the VSM
VSM can be simplified through the use of layers
Patented technology developed by CreateASoft
Allows the value stream to be viewed at varying levels of detail.
One stream can act as the supplier or consumer to one or more streams
Each layer can be represented as a single process or a collection of processes
Enhances the visibility and representation of the VSM
Forces the interaction requirement between multiple VSMs
The Value Network Map
the value stream changes based on the current production schedule
High mix/low volume
The value network map displays information per product family for each process
Provides greater visibility into the value stream
Helps identify waste areas
Prioritize Kaizen events
Ability to single out a product or a combination of products for more in-depth analysis
The Role of Dynamic VSM/VNM
Issues facing the Job shop:
Routing will vary per job
Job mix varies constantly
Resource allocation issues
Lead time control
Dynamic VSM/VNM updates the contents of the VSM/VNM based on the input constraints, without user interaction
Impact on the Big Picture
By allowing the VSM/VNM to be dynamic, flow constraints and routing changes have a direct impact on results
Lead times, VAT, waste time are automatically identified
Critical path is computed
Interactions between multiple streams is simulated, with problems dynamically identified
Faster results, better control over the operation
The Job Shop schedule
The presence of monuments increases the complexity of the schedule
Scheduling must be dynamic
Priorities, job status, impact of other equipment
Must maintain the waste reduction achieved in the Kaizen events
Optimize the monument efficiency and reduce change over time

Tools/Examples
Dynamic Simulator(s)
Constantly forecast the future of the value stream
Update schedule based on current state
Dynamic creation and tracking of the value network map
Use of RFID or Barcodes
Tie in with the simulator to provide ultimate results
Can provide a virtual camera into the operation
