Lean Flashcards
What are some principles of a lean operating system
Eliminate waste (activities that does not add value), Increase speed and response time and improve quality to reduce cost
Name 6 lean tools
5Ss, Visual controls, SMED single minute exchange of Dies, Small batch and single piece flow, quality and continous improvement, total productive maintanence TPM
Explain the five S prnciple
- sort, 2. set in (logical) order, 3. shine (clean & tidy), 4. standardize and 5. sustain (keep the process going through training and culture)
What are visual controls
Visual signs in the workplace that makes the employees understand it. The signs are called andons

What are pull systems

Pull
How do you calculate how many kanban cards you need
average daily production rate times (waiting time as fraction of day plus lead time) times 1 plus a policy cariable divided by the capacity of a standard container
