The effect of the major losses during a start up
Launching Costs = Category “A” + Category “B”
Launching Costs: Operating Losses-Category “A”
Components of Category “A”:
- Costs per shift
- Depreciation cost per shift;
- Labor cost per shift;
- Utility cost per shift;
- Maintenance cost per shift.
Calculation of Category “A” Losses
- Cs=Costs per shift
- Pr=Cases produced
- Pl=Cases planned
- Sh=Number of shifts in production
Launching Costs: Production Losses-Category “B”
Production Quantity Losses:
- PQL=Production Quality Losses
- Cs=Cases Supplied
- Pr=Cases Produced
- Pl=Cases Planned
PQL=(Cs-Pr)Cost per unit
Yield%=Pr/Pl
Production Losses Example
Production Losses
Production Loss Quantity
Quantity Loss=(Cases Supplied/Cases Produced) X Cost Per Unit
100 oz. Cases Produced 185824
100 oz. COB’s Supplied 196833
Yield 94.41%
Total Production Quantity Losses $24,404.03
Quality Losses
- Warehousing Costs includes cost of storage and handling charges while awaiting hold determination.
- Repack Costs include scrapping costs per case and pallet handling charges.
- Packing Material Losses include cost of packing material and cost of disposal.
- Formulation Losses include cost of raw materials and cost of disposal.
- If product is sold to a off quality customer, the cost under normal cost is a loss

Changeover Losses
Changeover losses occur when there is a size change or a product change.
$COTL=Changeover Time Loss
COTL= Time to complete changeover-Time expected
(If COT<0 do not continue
(If COT>0 then
$COTL=(COTL)(Operating Costs per hour)
$COPL=Changeover Production Loss
COP%=Cases Produced/Cases Planned
(If COP%<=1 for one hour do not continue)
(If COP%> 1then
$COPL=(#of hours of COP% <1)(1-COP%))(Operating Cost per hour)
$COL=$COTL + $COPL
Changeover Loss Example
A change over takes 5 1/2 hours. It is planned for 4 hours. When the line starts up, it is expected to run 1000 cases per hour. It runs 400 the first hour and 800 the second hour and 1000 the third hour. What are the Changeover losses?
$COTL=(COT)(Operating Costs per hour)
$COTL= (5.5-4)($162/hr)=$243
$COPL=(#of hours of COP% <1)(1-COP%))(Operating Cost per hour)
$COPL=2(1-(1200/2000)($162)=$129
$COL=$COTL + $COPL=$369
Customer Service Losses
If there is a loss of business due to missed shipment, this cost is a customer service loss. If the product is sold at a cost less than is customary, the difference between customary and cost recovered is a loss.
