内容简介：Traditional Divided Process
Divisions of the Complex Problem
Division by planning time horizon
long-term/strategic, medium-term/tactical, and short-term/operational
Division by different constraint concerns
material constraint / capacity constraint
manufacturing constraint / distribution constraint
Division by different detail levels
master production scheduling / detailed scheduling
strategic capacity planning / detailed resource planning
demand promising / due date quote
Deficiencies of the Traditional Process
Divisions to simplify the software
complexity is minimized by breaking up the problem
local optimums do not sum up to a global optimum
burden is shifted to human planner
Divisions lead to iteration
only part of the whole problem is considered by each planning tool
plan results and problems are propagated among tools
iteration is needed to achieve a better plan quality
Manual iteration is impractical
manual effect analyses of changes made
manual judgement to make changes
Drivers of New Planning System
Computing power has changed
hardware capability has advanced dramatically
software design has advanced significantly
friendly user graphical interfaces
Planning problem has changed
1980’s competitive drivers - TQM and JIT
1990’s competitive drivers - responsiveness and flexibility
accurate, real-time, dynamic planning capabilities required
Planning process must change
BPR/TOC
enhancing the competitiveness instead of automating the business process
Supply Chain Optimization / Foundation of eB: Advanced Planning and Scheduling (APS)
Is a redesign of the overall planning process that integrates the process across several dimensions
Addresses the whole planning problem directly, rather than dealing with small parts of the problem separately
Concurrent Planning
Integrated Planning
The Integration of APS
Integrating master and execution planning
Integrating material and capacity
Integrating manual and automated planning
Making order promising dynamic and real-time
