recommendation aur lia de larrard
Recommendation (Aurélia de Larrard)
  • We recommend building a major warehouse in Los Angeles
  • Building a major warehouse will allow:
    • Reduced use of air shipment on the west coast
    • Lower inventory in regional (west) CMSCs
    • Lower utilization rate of current warehouses W34-W87
    • Reduce the fluctuation of the whole supply chain
    • Increase Service Level
pros and cons of the other options aur lia
Pros and Cons of the other options (Aurélia)
  • Build a new CMSC (option 1)
    • Pros
    • Increase responsiveness
    • Reduce regional logistics costs
    • Cons
    • increase overall inventory
    • No reduction of air shipment
    • no improvement of warehouse capacity/high utilization rate
  • Extend plant storage of CMSC (option 3)
    • Pros
    • Lower investment cost
    • Improve local performance of close CMSCs
    • Cons
    • Limited capacity to reduce air shipment
    • Limited capacity to improve total inventory level
reducing air shipment cost yuji sakakibara
Reducing Air shipment Cost (Yuji Sakakibara)
  • 2 modes of transportation
    • Truck: majority of the shipment
    • Air: emergency shipment
  • If EATON can achieve 100% Service Level, they do not have to use air shipment
  • Service Level (SL)=1 – (Air shipment / Total shipment)
analyzing current inventory yuji sakakibara
Analyzing Current Inventory(Yuji Sakakibara)


EX) Los Angeles-SAT


Air: 16% of total shipment

SS = Inventory + (COGS/10cycle/2)


σ=SS/Z(Standard Deviation/Month)

Standard DeviationofDemand in each city

Pooling Inventory (BayuDaryanto)

Current System

Pooling System

Std. dev. demand at W = √N * σ

Std. dev. demand at 1 location =σ

Safety stock at W = z * √N∗ σ

Safety stock at each CMSC = z * σ

Total safety stock at N RDCs = N z σ
