Overview

• Definition of Advanced Planning and Scheduling
  (APS)
• Explanation of what APS does
• Explanation of how it works
• Practice with APS technologies
• Example of APS working for a real company
• Brainstorming on how it could work for you
• Implementing APS in your own firm

Introduction
As the manufacturing world pushes toward new
business standards, demand is increasing for an
integrated system that can support shifting
decisions in supply chain management. Luckily,
APS could be the answer.
4
What is APS?

• Advanced Planning and Scheduling (APS) is a
  software system that uses intelligent analytical
  tools to perform finite scheduling and produce
  realistic plans.

5
Nuts and Bolts of APS

• APS uses Finite Scheduling
• Finite scheduling is a process that assumes a
  fixed maximum capacity and sequences jobs
  according to actual company constraints.
• It creates more realistic forecasts than
  infinite scheduling methods

6
Nuts and Bolts of APS

• APS does Advanced Scheduling
• Advanced scheduling
• Considers plant capacity
• Considers business limitations

7
Nuts and Bolts of APS

• APS does Advanced Planning
• Advanced planning
• Considers the organization of machines and work
  cells
• Considers business objectives

8
Nuts and Bolts of APS

• Together, Advanced Scheduling and Advanced
  Planning
• Comprise the APS system
• Use finite planning and scheduling tactics
• Improve the accuracy of the production process
• Perform multiple data passes to optimize plans
  and schedules

9
What can APS do?

• Compare supply chain performance to increase
  accuracy
• Operate in real-time
• Reduce inventories
• Improve customer delivery times
• Increase utilization of resources
• Enhance efficiency of asset deployment

10
What about the old systems?

• APS was designed to
• Resolve problems with ERP systems
• Improve on MRP processes
• Employ more advanced technologies

11
How does APS work?

• APS systems
• Follow a four part model
• Utilize company specific constraints
• Employ advanced mathematical technologies

A little APS Review

• APS Systems
• Support decision making in the supply chain
• Use finite scheduling to consider actual company
  constraints and create accurate real-time plans
  and schedules
• Employ advanced mathematical technologies to
  develop efficient and effective results

The BIG Question
Has APS been successful?
20
Rohm Haas Example

• Rohm and Haas
• A specialty chemical company
• Manufactures over 200,000 SKUs
• Has 60 plants on 6 continents
• Objective
• Provide 100 customer satisfaction, while
  reducing inventory to minimal levels.

21
Rohm and Hass (continued)

• Decision
• To implement Manugistics netWORKS APS
  solution
•  Outcome
• Reduced inventories by 300-400 million
• Enhanced customer satisfaction
•  

22
Brainstorming

• How could Advanced Planning and Scheduling be
  used to improve your firm?

23
Implementing APS in your Firm

• How should you decide on an APS system for your
  organization?
• Define your goals and objectives
• Develop a reason for purchasing the system
• Select software that matches the needs of your
  company

24
Implementing APS (continued)

• How should your organization implement APS?
• Comprise an implementation team
• Executive sponsor
• Project manager
• Steering committee
• Knowledge experts
• Project team members

25
Conclusion

• This presentation has provided you with
  information on APS, its inner workings, the
  benefits it provides, and the ways it can be
  implemented into your own organization.
• Perhaps this system can be the future of supply
  chain support in your firm.
