							Citation: Experience MES
Now too many new terms and abbreviations are so many people do not easily
understood, MES also exists the situation. Many companies want to know MES, but
only see articles or hear people speaking, always can not find my true feelings. In fact,
MES is not a mystery, while you go shopping, you can experience the side. This
article about an alias for the Japanese to the MES, MES enables us to understand how
the same thing.
   MES (ManufacturingExecutionSystem) directly to create operating system,
commonly known as the production management system. Until 1990, it organized by
the          AMR             (American          consulting         research         firm
AdvancedManufacturingResearch-AMR) proposed and introduced.位于 U.S. MESA
Association        (ManufacturingExecutionSystemAssociationInternational)            was
established in 1992, AMR Zuzhizhihou is Ji, Wei Cujin MES Puji and Biaozhun
Hua's body, Gai associations have regular Fabu on MES Baipi Shu, along
with consumers Shi Yong's Xiao Guo Diaochabaogu after MES. They
made 11 MES main functions: (1) production of resource allocation and monitoring;
(2) planning and scheduling work; (3) process management specifications; (4) data
collection; (5) Operating staff management; ( 6) quality management; (7) process
management; (8) equipment maintenance; (9) Performance analysis; (10) production
unit scheduling; (11) product tracking. MES applications and for long been engaged
in research personnel, these definitions are easy to understand, but the initial contact
with MES are concerned, I really do not know where to start with we go.
   Japanese and Korean early as the beginning of an image of MES alias: POP
(PointofProduction), can be described as very appropriate for beginners. Carefully
observe the plant's production, will find each operator in a different
"points" on the job, these points bears a lot of production
information: plans or work orders, products, technology, personnel, quality, input and
output, equipment, efficiency and so on. So the point is that we analyze the basic
elements of production. In addition, a number of points can be strung together into
lines, many lines can also form a plane, or even multi-dimensional to
three-dimensional analysis, this name is wonderful. If it is a large group, the company
has many divisions, there are many factories in each cause of his men, then the point
here is different, and in the eyes of top management, a factory is a point, therefore,
also " point "in the eyes of the different roles are not different.
This chapter started from the production site, to discuss senior management issues
further discussion in later chapters.
   Different operating point (also known as the station), their concerns focus on the
means and access to data there are differences. In the electronics assembly industry,
some work is assembled by hand, some automation equipment (such as SMT), some
station using visual inspection, while others use equipment test, in addition 包装,
OQC inspection division of different business distinction Therefore, these station
contains very rich information.
   POP name is reminiscent of POS (PointofSales), POS terminal is supermarket sales.
If POP is a manufacturing execution system prototype, it can also supermarket sales
of POS as the implementation of the system. We have the experience of supermarket
shopping, with shopping cart or basket to the selection of goods to a cashier, the
cashier will have each item individually with a bar code scan gun, then POS system
will automatically calculate the total price, if you are a member, cashier will scan the
membership card is also the first, so that you can enjoy the points or discounts. In the
eyes of many, either POP or POS, not much magic, and will ask: "What the
supermarket and workshops with it?"
   Supermarkets have been caused by the operating mode of production model of
revolution. Well-known lean manufacturing originated in Japan, Toyota is Taiichi
Ohno. First resistance Ono Who? He is the founder of Toyota Production System and
the advocates, by the Japanese as: "the father of Japan's
revival," "production management of the Godfather,"
"wearing clothes of the saints", and Taiichi Ohno should be the
first supermarket to be grateful . Toyota was not only facing a shortage of funds, also
faces shortages of raw materials, in the face of such grim realities, Toyota made:
reduce costs, eliminate unnecessary waste. Otherwise, Japan's auto
industry will be hard to sustain! But how to do large-scale reduce costs and waste?
Supermarkets gave him inspiration.
   In the Toyota plant, because of the failure of the various processes at different times,
resulting in some parts of production processes and more, some less production of
components, not only does not lead to the production line running smoothly, and the
cycle to create inventory. In order to solve these problems, Taiichi Ohno from the
United States inspired by supermarket pickup - a matter of fact, Taiichi Ohno is
simply not seen the U.S. supermarkets, but I heard it. But this did not prevent him
from thinking and benefit from - he began a process of assuming no waste. Based on
this assumption, Taiichi Ohno created before the process after the process to pick the
process, so that push pull type production into production. Finally a pull about each
process, this production of a tight rope on the tight, driving on a process operation,
thereby eliminating the stock. (See "Chinese and foreign
management" in 2007 the second phase of the "Toyota managed
to open the black box: from the TPS to TOTALTPS", Deng Yang grid)
Taiichi Ohno was inspired from the supermarket changed the fate of Toyota. Today
Toyota is the case, though not the raw materials in short supply, but reduce the
product cost is always a business to survive.
   If Taiichi Ohno was not seen supermarket, now the supermarkets have made great
progress, and increasing scale, POS system is its revolutionary one of the weapons.
Personally think that POS system has the following advantages:
   1, using bar code technology, improve cashier efficiency and reduce emission on
the time customers
   2, improved billing accuracy
   3, in time the output list of goods so that customers can easily check accounts
   4, can be used to analyze sales data, provide the basis for the replenishment, and
can analyze customer buying preferences, and the demand for seasonal goods
   5, can record the cashier sales running account for duty to the people
   Then, bar code technology combined with the acquisition of such terminal
technology, it is similar to the same JIT production management revolution? View
from the electronic assembly industry, POP and POS have a lot of similarities.
   1, electronic assembly industry, production processes, product flows are generally
OnePieceFlow, bar code can be posted or linked to the way card identification
process;
   2, when the product flow through each site, can use the scanner to read product
information, so accurate and fast;
   3 key components can be identified using bar code, and associate products
   4, the production process of the bar code identification, customer barcode, carton
barcode can also associate
   5, the production process can be a variety of undesirable phenomena, to bar code
placed in the station to quickly scan records of workers

   7, the data collected can be shared with customers, collaborative management of
the production process, improve customer satisfaction.
   POP and POS in the data collection methods is a bit different. POS is the intention
of the single, mainly records of goods and receivables, and POP workshop station due
to the difference between the need to use different data collection equipment and
technology. POP collection methods can be divided into the following categories:
   1, a separate PC machine: mainly used for more complex work station, such as
packing station, not only approved for submission OQC generation, but also to record
the product packaging and interior, and even some customer numbers and product
packaging serial number must be strictly between the checksum algorithm to ensure
proper packing.
   2, DCT (DataCollectionTerminal): This device shows only relatively simple, low
cost, simple operation, small footprint.
   3, and test the software communications PC: always test equipment manufacturers
to provide PC computer and test equipment online, then the POP software can capture
data from product testing.
   4, PDA: suitable for a wide range of needs across more space, for example, need to
travel to the warehouse and shipping terminals, between the device more convenient.
   These devices can also be sensors, warning lights and other accessories combine
the best results.
   MES is needed is real kung fu, the martial arts is not knowledge but experience.
MES on the perpetrators has two tests: First, understand the various management
roles to view the data needs of targeted content and methods of design data presented;
second site with IE and other technical personnel allowed the data acquisition to
achieve efficient and accurate. Beginners think that these devices may be placed to the
station to allow workers to operate on it, but would like it too simple. In the pipeline
operation mode, the beat between the station Pingheng important, and computer
operators is limited, if not convenient for workers 简单 operation method, then the
MES Jiuhui turning into a drag, play the opposite effect. For example, in the office
you can easily operate a computer keyboard and mouse, but the production line in the
restricted space, no place to put the keyboard, and mouse simply can not be used in
the pipeline, especially the optical mouse, the anti-static pads on is not working,
computer failure, the technician so he had to operate the mouse on its own legs up,
such scenes are generally not easy to pay attention. In addition, there are many lines
and computer testing equipment, how to use the limited space layout of the equipment?
Some products are small, fast flow, how to ensure a coordinated data collection and
rapid production? Operator action is not correct, what is clear and easy to understand
tips for?
   As the collection equipment is cost, and therefore need to make a balance between
benefits and costs:
   1, not all work places need to do data collection, only the most needed points
before deployment;
   2, to collect data as far as possible without increasing manpower, personnel costs
increased mean;
   3 and in some cases, existing processes need to be combined with the data
collection re-optimization, if necessary, to conduct process reengineering.
   By optimizing the process, save a collection point to 5,000 yuan to calculate that if
50 production lines, then is equivalent to saving 25 million investment, will be saved
by an officer, according to the monthly cost of 1,600 yuan per person basis, even if all
about benefits into account, the year that saved the man can save 20,000. 50 provinces
and one line, a total savings of 1000,000 million. In fact, adding that would lead to
extension of the production cycle, shrinking output per unit of time, thereby reducing
the number of personnel on the contribution of the production efficiency is no small
matter.
   The world's most intelligent people are businessmen, and commercial
production as the purpose is to profit, the supermarket is the place most worth
learning. Through POP, you can help build the database production process, which
features 11 MES only become a tree. MES data provided for managers, a huge help
for lean production to enable enterprises to continuously reduce costs, improve
efficiency, access to breakthrough.
