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

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
