The document compares different scheduling approaches: Advanced Planning and Scheduling (APS), Enterprise Resource Planning (ERP), Theory of Constraints (ToC), and Lean Manufacturing scheduling. It discusses how each approach handles resources, calendars, changeovers, material requirements planning, flexibility, and other factors. It also provides a comparison of various APS systems and their key capabilities.

About me
My name is Janusz Pieklik. He has
been dealing with management
systems for over 25 years. With my
knowledge I have supported over 300
projects in the world. I have trained
thousands of people, developed
hundreds of management concepts.
During this time I got to know in detail
all the significant ERP, APS, MES,
CMMS class systems on the market,
etc. I share some of this knowledge
free of charge in this video. Nice
watch. If you like it, give me a like.
Thank you in advance.

Resource Management Focus on all resources Focus on cells Focus on Piecemaker Focus on Constraints
Calendar Management
The calendar of each
resource is valid

Takt Time and Cycle Time
are important
The restriction calendar is

Changeover
A variety of algorithms to
optimize setup and
teardown
No optimization SMED
Focus on changeovers on
