- Methods of Waste Eliminiation
- Eliminate, Combine, Simplify
- 5S
- Sort, Set in Order, Shine, Standardize, Sustain
- 4P model of Lean
- People, process, philosophy, problem solving
- Most important measure in value stream mapping
- Product Lead Time, Total Process Time
- Components of Lean Pillars
- JIT, Jidoka, Standardization, Kaizen, Quality lead time cost, (mutual trust & employeed development, robust process, supplier and products)
- first priority in problem solving
- preventing defect from getting to customer
- 2 types of process improvement
- flow kaizen point kaizen
- 2 ways to create flow if none
- supermarket buffer
- Kanban enablers
- quick changeover point of use inclusion stable process level production
- Min number of Kanban signals needed
- Demand*lead time* s.f. /parts per container
- 3 ways to prioritize improvements
- frequency effect consequences detectability
- takt time equation
- available working time/demand rate
- pitch
- takt time*batch or ship size
- Heijunk definition
- leveled demand (volume and product mix)
- 3 kinds of work
- Value Added Non-value Added Incidental (non-value added essential)
- Benefits of standard work
- everyone does the same thing, quality, documented, 1st step in problem solving,
- Def of standard work
- Best current documented method
- # operators needed
- total cell process time/takt time
- 3 types of error proofing/inspection
- human/manual warning control
- % effectiveness of manual inspection
- 70-80% = some defects go to customer
- Use of Andon
- call for help so line doesn't have to stop, team leader should respond
- Supply Chain Considerations
- Cost, quality, responsiveness, dependability
- long supply chain consequences
- up risk, up cost, up margin of error - ex. engineering changes and responsiveness effects
- Things needed for effective supply chain
- process orientation, customer focus, teamwork
- Where do you start for change implementation?
- process change, not culture change
- Role of leader (6)
- Vision, tools and resources, metrics, measure gap, policy, strategy
- Role of manager
- lead actual change, cope with comlpexity
- Why aren't processes always linked in continuous flow?
- variation machine capability facility layout batch size supplier distance
- 7 steps fot cell design
- 1). calc takt time 2). map processing steps 3). Calc machine capacity requirement 4). create work cell layout 5). determine operator balance 6). design material flow 7). design information flow
- net machine cycle time equation
- machine cyle time + load/unload time /(1-downtime)(1-scrap)
