Key variable in elementary inventory calculations - Q - lot size
D - annual demand
C - cost to purchase one unite
H - cost to hold on unit of inventory in one year
S - cost to place a single order
Annual cost to purchase inventory - DC
Annual Holding Cost (AHC) - (Q/2)*H
Annual Ordering Cost (AOC) - (D/Q)S
Equation for total cost - DC + AHC + AOC
Economic Order Quantity (EOQ) - the lot size that minimizes total annual inventory
holding and ordering costs, making it the optimal lot size
= SQRT (2DS/H)
if a manager is looking to minimize inventory costs and maximize total annual savings
then he would calculate optimal lot size through this formula.
Cycle time - the pace at which product must move through the assembly line in order
for the assembly line to keep pace with demand.
= Operating Time/D
Theoretical Minimum number of workstations calculations (TM) - total task time / cycle
time

get parts prepared in time for manufacturer.

completed. Example, a partially assembled shovel.
Finished Goods - items that have completed manufacturing and are ready for shipment.
Maintenance, Repair, and Operations (MRO) - Items that are not intended for the
Finished
