Information flows logistics
Information logistics is part of a comprehensive
business logistics, which encompasses logistics of
goods and services as well as financial logistics,
Logistics is the flow
of goods,
but also of information.
The information flow refers
to the planning, steering and controlling of all
information for the fulfilment of the customer inquiry
across all business steps, from booking until invoicing.
Information flows
Feed-forward information
ahead of delivery – enables speedier delivery,
enhanced distribution, and earlier adoption by the
customer,
Information flows
Feed-back information
from the point-of-sale supports adoption of
distribution, inventory, production planning and
information and statistics
Information flows
Preliminary information:
Delivery schedules by the sender, or orders and reservations for
initialising this process.
Information flows
In advance information:
Will be sent to the other business contractor before the
transport process itself will start.
Following process can be started earlier and process lead times
can be reduced.
Information flows
Accompanying information:
Kind of a status report and enable plan versus real comparisons.
Besides, they contain also information about the correct
handling of the goods for the transport process.
Information flows
Concluding information:
Follow after the transport flow and constitute a confirmation of
the receipt of the goods in terms of for example invoices.
eFreight and IT-trends
Freight Transport Logistics focuses on the planning,
organisation, management, control and execution of
freight transport operations in the supply chain.
It is one of the drivers of European competitiveness.
Production and distribution networks depend on
high-quality, efficient logistics chains to organise the
transport of raw materials and finished goods across
the EU and beyond.
Estimates put the share of the logistics industry in
Europe at close to 14% of Gross Domestic Product
(GDP).
European integration, liberalisation and the relatively
low cost of freight transport
eFreight and IT-trends
Intelligent Transport Systems (ITS)
apply information and communication technologies to
transport.
eFreight and IT-trends
Today: “Internet for people”.
Tomorrow: “Internet for cargo” (eFreight concept)
Trend: ITS information for T&L

RFID - Introduction
Radio frequency identification (RFID) technology
is one of the most promising auto-identification
and data capture (AIDC) technologies.
It uses electromagnetic waves to transmit realtime
data to identify specific objects.
An RFID system consists of three basic
components:
Tag: identifies the item to which it is affixed and
communicates with the reader via radio signals.
Reader : converts the radio signals into data that can be
passed onto the
middleware : to trigger further actions, based on the identifying information.
RFID – Identification
RFID tags are not a new technology,
The purpose of an RFID system is to enable data to
be transmitted by a portable device (tag) which is
read by an RFID reader and processed,
RFID can be used to identify, track, sort or detect a
wide variety of objects (e.g. pallets, cases,
containers).
What is reader collision?
The signal from one reader can interfere with the signal
from another where coverage overlaps.
One way to avoid the problem is that the readers are
instructed to read at different times, rather than both
trying to read at the same time.
What is tag collision?
Another problem readers have is reading a lot of chips
in the same field. Tag collision occurs when more than
one chip reflects back a signal at the same time,
confusing the reader.
