TESTE DEIN WISSEN

What is a methodological approach of Lean Production?

Lösung anzeigen
TESTE DEIN WISSEN

- Only bottlenecks show us

a) the potential 

b) their priority 

- you have to allow bottlenecks, but make them visible and measurable and identify permanently (push bottleneck-visibility, possibly artificial) 

- Get active: Focus on the bottlenecks, with priority, and focus the problem solving energy on the point. Make sure, they get eliminated at once (lasting)

- permanently means: repetitive/ "infinity" repeated

Which technical factors are influencing assembly? 
Lösung anzeigen
TESTE DEIN WISSEN
- Product dimensions
- number of components
- product structure
- product variants 
- material properties, mass
- assembly processes with difficulty

TESTE DEIN WISSEN

Under which circumstances which assembly version is better suitable?

Lösung anzeigen
TESTE DEIN WISSEN

If costs have to reduced or/ and a middle to high quantitiy has to be reached, then task-by-task assembly can be used.


If a low quantity has to be made and skilled employees are available then piecewise assembly can be used.

What are the ergonomic requierements on assembly systems?

Lösung anzeigen
TESTE DEIN WISSEN

- Avoid bending over / strained postures 

- Assembly systems must be adapted to the human body size

What is the description of flow-line assembly?

Lösung anzeigen
TESTE DEIN WISSEN

- Workplaces (here) arranged in a star shape

- Employees work at a dedicated workplaces 

- Seated/ standing workplaces 

- Less/ little buffer between the workplaces -> "Flow-line assembly" 

- rare as hybrid systems

TESTE DEIN WISSEN

What is the differnences of local/box and flow- line assembly and where do they have impact on?

Lösung anzeigen
TESTE DEIN WISSEN

Local/box assembly 

 (construction site assembly): 

- lots of material and information flow

- high requierements on synchronisation

+ very high flexibility in assembly 


Flow- line assembly: 

- (once) preplanning extensive, higher requierements on punctuality

+ short and straight material and information channels; good transparency and feasibility

+ standardisation, planning certainty 

+ productivity 


Impact on logistics!
