Q

What is PoD – Pro­duc­tion-ori­ent­ed De­sign?

A

Pro­duc­tion-ori­ent­ed De­sign (PoD) ad­justs prod­uct concepts and re­al­iza­tion of their de­sign to the re­quirements of pro­duc­tion - in­clud­ing vari­ance and va­ri­ety.

It defines the basis for a cost-efficient Production

Q

What is the definition of PoD – Pro­duc­tion-ori­ent­ed De­sign?

A

PoD is a con­tin­u­ous process for com­pre­hen­sive prod­uct de­sign im­prove­ment with re­gard to safe­ty, qual­i­ty, pro­duc­tiv­i­ty and costs.

Q

What are PoD findings based on?

A

Pro­duc­tion-ori­ent­ed De­sign (PoD) ad­justs prod­uct con­cepts and re­al­iza­tion of their de­sign to the re­quire­ments of pro­duc­tion - in­clud­ing vari­ance and va­ri­ety.

  • Smooth, synchronized production in a string of pearls over the whole process chain
  • Delivery of purchased parts and sub-assemblies in a synchronized sequence
  • Pull production with demand oriented, high-frequency material supply in small quantities
  • No buffer inside the Plant, direct connection of sub-processes to the main line in one-piece flow
  • Continual product flow without buffer and maximum flexibility
  • Production in customer takt in all production steps
  • Minimized order lead time, shorter than customer expectation
  • Material flow routes are short and do not cross

Q

In reality the design of Plant layouts is always a compromise between what?

A

between TOS requirements and real general conditions

69
Q

What are TOS requirements for Plant layouts?

A
  • Integration of all relevant TOS methods
  • Lean and stable processes with minimum stock levels
  • Synchronized value stream in customer takt
  • High machine availability (OEE) with min change over times
  • Logistics in continual flow
  • Smooth volume flows
  • Max flexibility
  • Min variability
  • Waste-free processes
  • built quality instead of proved quality
70
Q

What are factors to consider for Plant design?

A
  • Op­ti­mum com­pro­mise be­tween ex­ist­ing gen­er­al con­di­tions and the TOS re­quire­ments.
  • The lay­out de­sign not only takes ex­ter­nal fac­tors into ac­count e.g. mar­ket re­quire­ments), but also in­ter­nal ones (e.g. or­ga­ni­za­tion)

• Complicated material supply
• Traffic jams on transport routes

inflexibility
• No extendible area
