An Empirical Study of the Machine Assembly Efficiency Improvement Based on Lean Six Sigma Technique
Effectively controlling inventory is one of the key factors for small and medium-sized enterprises to make profit. Most small and medium-sized enterprises solve their problems through experience or trial and error, but they are often unable to achieve the desired enterprise performance under limited...

Effectively controlling inventory is one of the key factors for small and medium-sized enterprises to make profit.
