well..im searchin 4 new technics in production planning and the ways that streamline works and create an environment with better machines lay out and other stuffs ...actually there are a lot of algorithms and solutions..but ona the most popular technics nowadays is genetic algorithm..well i thought that its a good start 4 this issue to share some kinda new information bout it..
i will be really gratefull if u have some stuffs too!!

...this is somethin but not that perfect...
tell me ur pointa view!!

In the business world the method that a particular company uses to get its
products from the factory to the consumer varies. These methods are very
sophisticated and often define the profitability, quality and ultimately
the success or failure of a particular business. One particular
logistical system that is interesting is the system that Dell uses to
deliver its computers from the factory to the customer's location.

If you have ever purchased a Dell computer you know that you are allowed
to completely customize your computer and that Dell guarantees delivery of
your computer in a certain time frame. To provide such a tremendous
service to their customers it would seem to cost Dell a tremendous amount
in unused inventory and storage costs. One would even wonder how Dell can
afford to operate like this. The truth is that Dell actually carries no
inventory and that they in fact force their suppliers to carry all the
inventory and therefore the suppliers also assume all the risks and costs
associated with this inventory.

The first step in this incredibly profitable logistical system is when the
customer enters his specifications for the computer that he or she will
purchase. When Dell receives and processes this information, they send an
order out to each individual supplier and they transport each part to a
location where the product can be assembled. Then Dell simply assembles
the item and ships it out to the customer. Dell is not responsible for
any inventory and even more incredibly does not have to pay for any unused
parts. Dell's logistical system works almost flawlessly and it would seem
to the casual observer that Dell has really designed an ingenious system
that allows them to run their business in this manner. However the
reality is that a logistics system like this has been come up with before,
but the difference is that no other company has been able to convince its
suppliers to go along with an arrangement which will cost them so much.
It is very difficult for a company to convince a supplier to guarantee
that a certain number of parts will be in stock and ready for use and to
not offer a guarantee in return that they will be paid for the parts.
From a supplier's point of view it would not be beneficial to assume all
the risk of unused inventory.

How Dell convinces its suppliers to agree to take part in a system in
which the supplier will assume all of the responsibility for the
over-forecasting of sales and unsold parts is still a mystery. One of the
only possibilities is that Dell chooses small suppliers and makes sure
that the majority of their business is done at Dell. Dell then leverages
this position and coerces them into taking part in a logistical system
that is clearly not beneficial to the supplier. In order for the supplier
to allow this to happen Dell has to keep sales high so that Dell can give
the individual suppliers enough business to stay afloat and be profitable.
This is of course easier said than done and this is the reason that Dell
is one of the only companies that can offer a customizable product that
can be assembled and delivered quickly to the consumer.

hey guys .....indeed im doin my best to gather all information bout logistic..SCM...production systems and so forth...i hope u be my best partners on this issue

Logistics has become an integral part of supply chain management. Five
years ago, the core focus of supply chain management was streamlining
material movement within the factory and ensuring that the right material
was in front of the machine at the right time. There was very little
focus on the logistical movement of material since most of the supply came
from suppliers who were located in and around the factory. This, in fact,
used to be a central premise of Just-In-Time Manufacturing that stated
that material suppliers had to be located within a few miles of the
assembly line, so they could supply material in smaller quantities and
more frequently.

Today, the entire manufacturing environment has been completely
transformed. Globalization and outsourcing has created a scenario where
critical parts and many sub-assemblies are being manufactured in different
parts of the world and then shipped into the manufacturing location. To
be competitive, manufacturers have realized that they need to get these
parts assembled in countries where the cost of labor is significantly
lower than in the United States. This trend has forced companies to
invest in their logistics to ensure that their shipped materials arrive on
time. Over time, Logistics has also branched into several unique areas of
focus including warehousing, purchasing, shipment tracking and inventory
management.

This trend has also introduced a new entity in logistics management called
the third party logistics provider or 3PLs. These firms specialized in
outsourced logistics services, where they manage the shipment pick and
delivery on behalf of the manufacturer and ensure that the consignment is
shipped through the most optimal route, taking both cost and time into
consideration. 3PLs are also able to provide economies of scale, since
they can combine multiple orders across different customers into a single
shipment. 3PLs can also decide on alternate routes for shipments in case
of delays at various receiving locations.

3PLs have also started to offer their customers various sophisticated
services including bar coding, track and trace capabilities and inventory
hubs.

Bar-coding involves the process of labeling consignments with machine
readable bars that can be scanned at the point of origin, in transit
location and final destination. This allows for easier transactions and
handling of goods.

Track and trace involves the tracking of shipments as it moves from one
logistics point to another. This information is then fed back into a web
interface that can be accessed by customers. Track and trace systems can
perform highly complex calculations like computing re-routing of shipments
in case of delays, sending alerts to various users and monitoring
real-time shipment information.

nventory hub management or 3PL managed inventory is a specialized form of
logistics management where the 3PLs store inventory on behalf of their
suppliers. This inventory is usually stored in hubs that are located near
the manufacturing facility. When parts are required of suppliers in
international locations, 3PLs pick and ship the parts into the inventory
hub. These parts are held until required by the manufacturer.

Some of the prominent 3PLs today are Ryder, Hanjin Logistics, Penske
Logistics, ZIM Logistics, BAX Global, UPS and FedEx. Between them, they
account for billions of dollars worth of material
