Logistics
The
goal of logistic work is to
manage the completion of project
life cycles, supply chains
and
resultant
efficiencies. Often Logistics is termed
as the art and science of
managing and controlling
the
flow of goods, energy, information and
other resources like products,
services, and people,
from
the
source of production to the
marketplace.
It
also refers to the movement of materials and
information within a facility and to
incoming and
outgoing
shipments of goods and materials in a
supply chain.
Logistics
is the time related positioning of
resources and is commonly
seen as a branch of
engineering
which creates "people
systems" rather than
"machine systems. It involves
the
integration
of information, transportation,
inventory, warehousing, material
handling, and
packaging.

Logistics:
Evaluating Shipping
Alternatives
A
situation that arises
frequently in some businesses in
making a choice between quicker(
expensive)
shipping alternatives such as
overnight or 2 day air and
slower but cheaper
alternatives.
The decision in such cases
often focuses on the cost
savings of alternatives
versus
the increased holding cost
that result from using
slower alternative.
Often
the supplier gets paid on
delivery of the product through
EDI the very same time
the
order
reaches its
destination.
The
Incremental Holding cost
incurred by using the slower
alternative is computed as
follows:
Incremental
Holding Cost= H (
d/365)
Where
H=Annual Holding cost for
the item.
d
= Time savings in days and
d/365 is fraction of year
saved.
Logistics
Example
Determine
the shipping alternative ( with in
Pakistan) for a Karachi based
Montessori toy
manufacturer,1
days or 5 days are best
when the holding cost of the
item is Rs. 100,000 per year
and
the
1 day shipping cost is Rs
1500. and 3 day shipping
cost is
Rs.
600

Solution
H=
Rs. 100,000 per year
Time
savings = 2 days using 1 day
alternative
Holding
cost for additional 2
days
=
100,000 X ( 2/365)
=
Rs. 547.95=548.
Or
Holding cost per day = Rs.
274
Alternative
A
Cost
savings = Rs. (1500-600)= Rs.
900, because the actual cost of savings
of Rs 900 is more than
the
holding cost of Rs. 548,
use the 3 day option.
Cost
savings = Rs. (1500-500)= Rs.
1000, because the actual cost of savings
of Rs 1000 is greater
than
the holding cost of Rs.548,
use the 3 day option.
Distribution
Requirements Planning
Distribution
requirements planning (DRP) is a system
for inventory management and
distribution
planning.
Extends the concepts of MRPII.
Uses
of DRP
Management
uses DRP to plan and
coordinate:
1.
Transportation
2.
Warehousing
3.
Workers
4.
Equipment
5.
Financial
flows
Electronic
Data Interchange
EDI
is the direct transmission of inter-organizational
transactions, computer-to-computer,
including
purchase
orders, shipping notices, and debit or
credit memos.
Electronic
Data Interchange gives an organization
the following benefits and
advantages.
1.
Increased
productivity
2.
Reduction
of paperwork
3.
Lead
time and inventory
reduction
4.
Facilitation
of just-in-time systems
5.
Electronic
transfer of funds
6.
Improved
control of operations
7.
Reduction
in clerical labor
8.
Increased
accuracy

Efficient
Consumer Response
Efficient
consumer response (ECR) is a
supply chain management
initiative specific to the
food
industry.
ECR reflects companies' efforts to achieve
quick response using EDI and
bar codes.
E-Commerce:
is the use of electronic technology to
facilitate business transactions.
Successful
Supply Chain
1.
Trust
among trading partners
2.
Effective
communications
3.
Supply
chain visibility
4.
Event-management
capability
a.
The ability to detect and
respond to unplanned
events
5.
Performance metrics
Summary
Supply
Chain Management is primarily the
flow of information which
ensures the effective flow
of
materials
throughout the value chain.
The chain extends from the
Suppliers to the organization and
from
the
organization to the customers. Operations
Managers should be able to
identify that the strength of
the
Supply Chain is the strength of its
weakest link. If an organization
fails to make use of the
customer
feed
back it not only looses its
customer base but also
weakens its supply chain and
loses its business to
its
customers. Suppliers normally
come at the upstream of the organization
and customers at the
downstream
to complete the Supply Chain. Many
Software are available to
ensure that Supply chain
is
managed
effectively by the organization. Supply
Chain Management is now
gaining popularity in
Pakistan.
