Deseasonalization Vs Seasonal Index
Techniques
Quantitative
Methematics
Intrinsic(Time series)
Alpha(α) smoothing constant (0~1, usually 0~0.3)
New forecast = (α*最新需求)+（1-α）*过往的需求
Tracking
Deviation(Algebraic) Vs Error (Abs)
Mean Absolute Deviation(MAD)
F: Master planning
Priority planning
S & OP (Product family level)1-3 years
Master Scheduling(End-item level) 3-18months
MRP(Component level) 3-18months
MRP:Material requirement planning
Input,output and purpost of S&OP plan /master scheduling & MPS
MPS:Master Production Schedule
MS - realistic & Achievable
Valid Inventory or backlog
Valid number of changeovers
Heijunka for Lean production

Overview
Measurement System
Unit- standard time
Average worker
Lead time

Contract buying
MRP planned order release to supplier
J:Aggregate inventory management
Cost
Components of carrying cost
Components of ordering cost
FC statements & Inventory
Balance sheet
Assets = Liabilities + Owner's Equity
Cash Flows
Average Inventory and Inventory turnover
Inven. T = Annual COGS/ Average Inv.
FIFO,LIFO and Average Cost
Standard Cost Accounting Vs Lean Acc.
Policies & Control
Policies
Traceability and lot control
Safety Stock
SD = 1.2 MAD (Mean Absolute Deviation)
SS= SD * SD safety factor or MAD * MAD safety factor
Adjusting Lead Time
New SS = Old SS * SQRT(New lead time / Old lead time)
K:Item Inventory management
Control
A/B/C - by Value (B 30% by Qty)
Order Qty
Lot for lot
A items, expensive components
Large or bulky items (Material handing)
Fixed Order Quantity (FOQ)
Fixed lot size or multiples thereof
Basis(efficient production batch , etc)
Economic order quantity (EOQ)
Annual ordering cost = A * S / Q
Annual Carrying cost = (Q * c * i)/2
Total Inventory cost = Ordering cost + Carrying cost
Independent Demand ordering system
auditing Inventory records
L:Execution and Controal
Continuous improvement
Throughput Accounting
Net profit = Throughput -Operating Expense
Throughput = Rev. - True Variable Costs
Production Activity Control(PAC)
Scheduling and implementation
Scheduling
Final Assembly schedule (FAS)
M:Physical Distribution
Physical Distribution Overview
Physical Supply & Distribution Channels
Physical Distribution Vs Transaction Channels
Physical distribution stakeholders
Cost = Transportation + Carrying+packaging
Distribution Inventory
Distribution requirements planning
Warehousing
Location system
Fixed loation
50% of time half of location empty
