Transportation is important because it has a big impact in:
Costs (Transportation & Inventory carring cost)
Service level (OCT & Punctuality)
It represents 4/5% of the turnover
transportation cost
Intransit stock
Safty stock
Cycle stock
Types of inventories dealt when distribution networks.
SS= K x sD,LT
Safty Stock
K: Service Level coeficient
sD,LT: sqroot(ELT x sD2 x ED2 x sLT2)
2 al cuadrado
s: standard deviation
Can you explain the graph of Reorder Point model and say what is SS for
Y axis = quantity
X axis = time
SS is a base line in quantity to face unpredictable demand.
My ROP considers the transport LT and to be covered until that day in terms of Q but what I order is day 0 needs.
In transit stock
ITS = F x LT
F:Demand flow
LT: transportation lead time
Service Level:
Oreder Cycle Time
Order processing LT
Order preparation LT
Transportation LT
Includes all the services fo phisical movement of goods from POO to POD at a required time
Diferent modes, solutions, providers, infrastructures.
