PRODUCTION 
In the production control there are a few
methods
to
let the material flow go as smooth as possible through the section production.
Sometimes they are based on Japanese methods, sometimes on American industrial
experience. A fact is that you can't blame the Japanese production technology
for the recession in the Japanese economy, but the financial management
is to blame. This development makes it necessary to integrate the best
of both methods to create an own structure for an own identity in a good
management. In this way an "European" production control can grow in a
healthy economic climate. The philosophy behind the next methods shall
be ignored in the contemplation.
JUST IN TIME (JIT) is a method based on the rule that the (half)materials
must be delivered at the place of production just before the moment
that they are really necessary. The suppliers of these materials can be
other sections inside the company as well as external suppliers. In this
way an enormous discount in supply costs and transport costs can be realisated.
In the Japanese industrial situation, where this method is developed, there
are some suppliers who build complete factories close to their customers
who are manufacturing the final product. This method asks a high level
of information interchange in-between the sections or external suppliers.
OPTIMALIZATION PRODUCTION TECHNIQUES (OPT) is a method developed
in Israel. This method is based on a 'massage' of the flows in the production
line, the removing of bottlenecks in the manufacturing. For this method
it is necessary to research the flow in the production line before the
'massage'.
As mentioned before, there are several methods of
production control
in traditional style;
-
PROGRAMCONTROLED- On certain regulated impulses (ordertiming) the production
starts. (factories for canned vegetables, flower
farming, confection manufacturing, media as the daily paper)
-
SUPPLYCONTROLED- Production starts if a certain storage limit is passed.
(conserved
products, hotels and pubs, supermarkets and car industry)
-
ORDERCONTROLED- Specific products are manufactured for specific customers.
(building
for medical- and other special instruments, house building, shipbuilding)
These factors are only significant for the level of supply and don't effects
the routing or amount of information. With a
supplycontroled production
system the supply of material is called PUSH transport. If production runs
under order control, then the moving of supply material is called PULL
transport. Documentation(1) for the
supply of half material must be treated by the section production
because of the fact that these materials have been processed by the same
section (most of the time). By counting the total amount of material(2)
the section Productionorder will be able to get a secure overview of the
storage of these half materials, and it is possible in this way to calculate
the capacities(3)for every product.
The productionTRANSITtime(4)is reported
at the productionORDERsection, and contents facts like personal capacity,
machine capacity, amounts of material and the final amount of products.
These products are delivered to the magazine FINAL PRODUCTS, who is also
reporting
this amount of products(5) at the section
production orders. In this way there are 3 different registrations in this
section, namely supply of materials, supply of half materials and amount
of final products. This results in a total overview of the supplies on
the floor as well as a transit time of production.
