Production logistics:
The term is used for describing logistic
processes within an industry. The
purpose of production logistics is to
ensure that each machine and
workstation is being fed with the right
product in the right quantity and
quality at the right point in time.
Logistic regression:
logistic regression is a model used for prediction
of the probability of occurrence of an event. It
makes use of several predictor variables that may
be either numerical or categories. Logistic
regression is used extensively in the medical and
social sciences as well as marketing applications
such as prediction of a customer's propensity to
purchase a product or cease a subscription.
For example, the probability that a person has a heart attack within a specified time period might be predicted from knowledge of the person's age, sex and body mass index.
Extensions:
Extensions of the model cope with multi-category
dependent variables and ordinal dependent variables,
such as polynomial regression. Multi-class
classification by logistic regression is known as
multinomial logit modeling. An extension of the logistic
model to sets of interdependent variables is the
conditional random field.
Logistics map:
The logistic map is a polynomial mapping, often cited
as an archetypal example of how complex, chaotic
behavior can arise from very simple non-linear
dynamical equations. The map was popularized in a
seminal 1976 paper by the biologist Robert May, in
part as a discrete-time demographic model analogous
to the logistic equation first created by Pierre Francois
Verhulst. Mathematically, the logistic map is written
xn is a number between zero and one, and represents the
population at year
n, and hence
x0 represents the initial
population (at year 0)
r is a positive number, and represents a combined rate for
reproduction and starvation.

Supply Chain Management Problems:
Supply chain management (SCM) is the
process of planning, implementing, and
controlling the operations of the supply
chain as efficiently as possible. Supply
Chain Management spans all movement
and storage of raw materials, work-inprocess
inventory, and finished goods from
point-of-origin to point-of-consumption.
Distribution Network Configuration:
Number and
location of suppliers, production facilities,
distribution centers, warehouses and customers.
Distribution Strategy:
Information:
Integration of systems and processes
through the supply chain to share valuable
information, including demand signals, forecasts,
inventory and transportation.
Inventory Management:
Cash-Flow:
Arranging the payment terms and the
methodologies for exchanging funds across entities
within the supply chain.
Military logistics:
In military logistics, logistics officers manage how and when to move resources to the places they are needed. In military science, maintaining one's supply lines while disrupting those of the enemy is a crucial—some would say the most crucial —element of military stratagy, since an armed force without resources and transportation is defenselessMedical logistics:
Medical logistics is the logistics of pharmaceuticals, medical and surgical supplies, medical devices and equipment, and other products needed to support doctors, nurses, and other health and dental care providers.
Business logistics:
Basic logistics
What is logistics ?
Logistics is the art work of managing the
supply chain and science of dealing with
and controlling the go with the flow of products,
information and different resources like
strength and people among the factor of
foundation and the point of consumption in
order to satisfy customers' requirements.
It includes the mixing of records,
transportation, stock, warehousing,
material managing, and packaging.
Origins and definition:
The word of logistics originates from
the historical Greek trademarks (λόγος), which
approach “ratio, word, calculation,
cause, speech, oration”
The branch of technology having to do
with buying, retaining and
transporting material, employees and
centers.
