Ratio Statistics
Statistics related to this group provide detailed information
on the utilization of various supply chain elements during
the Simulation-based
experiments, as well as
quality of provided delivery services (based on the analysis of
the received (Fulfillment
Received (Orders On-time), Fulfillment Received
(Products On-time), Fulfillment
(Late Orders), Fulfillment
(Late Products)), sent (Demand
Placed (Orders) by Site
) or initially dropped (Demand Placed
(Dropped Products) by Customer, Demand Placed (Dropped
Orders) by Customer) orders/ordered products).
Bullwhip
Effect by Product
Shows statistics on product
demand variability amplification during the supply chain
simulation: from the point of actual (final) product items demand to
the
point of origin (DC, factory).
- BWE > 1 means that outgoing variability prevails
over the incoming
- 0 =< BWE < 1 means that incoming variability
prevails over the outgoing
- BWE = 1 means there is NO bullwhip effect
- BWE = -1 means that incoming variability is 0
The bullwhip effect is defined as:
Where:
- variance in demand
- expected value
- replenishment
history
-
incoming history
The data is:
- Updated each model run day.
- Collected per:
- Type - the type of object the data is
collected on (Customer, DC, Factory, Supplier).
- Object - the name of the
object (Customer, DC, Factory, Supplier) the data is
collected on.

on.
ELT Service
Level by Orders
Shows the service level based on the ratio of on time
orders to the overall number of outgoing orders.

calculated in the same way, the difference lies in the data extracted
from the calculation:
- ELT service Level by Products
- shows ratio of products delivered on time to the
overall number of products shipped. The data on
products is taken from the processed orders.
- ELT service Level by Revenue
- shows the ratio of on time orders to the overall number of outgoing
orders in terms of money received.

statistics shows service level calculated based on the
expected lead time.
The value is defined as:
Where:

number of
on time orders

of outgoing orders - the sum
of on time and delayed orders. The value does not
include placed orders
that are not yet shipped, delayed
or dropped (such orders can still be delivered within the Expected lead time specified in the Demand
table). Note
that for ELT-based service level, dropped orders are excluded from outgoing
orders if backorder policy for the selected
customer is set to Not
Allowed (backorder policy is defined in the Demand
table).
