The capacity of the 3 lines gains over 100,000 tons of product/year and is ISO 9001:
2000 qualified.
B. PART II: DESIGN OPERATIONS
III. MANAGEMENT QUALITY
There are many tasks to perform managing quality such as process strategy, location
strategies, layout strategies, human resources, supply- chain management, scheduling, and
maintenance. Each strategy as we mention above will be more detail in other specific part in
this report.
In this part of the case we mention about quality in East Asia company; we just focus on
International Quality Standard. As we know, there are tow ISO 9000 and 14000, in East Asia
company, they just apply ISO 9000.
Now how we can understand what ISO 9000 is and how East Asia can apply it.
What is ISO 9000?
A set of quality standards developed by the international standards Organization (ISO) such
as Quality management system, Management responsibility, Resource management,
Product realization, Measurement, analysis and improvement.
In East Asia how they can apply ISO 9000
It is very hard to go detail in this part, we just mention some main idea about ISO in Ton
Dong A.
Operations Management Report
Page 3
Quality management system
East Asia established and maintained a quality manual that includes the control of document
and control of record.
Management responsibility includes management commitment, customer focus, quality
policy, quality objectives, quality management system planning, management
representative, internal communication. For example, in management commitment, the top
management of East Asia company provide evidence of its commitment to the development
and implementation of the quality management system, or in internal communication, the
top management of this company ensured that that appropriate communication processes are
established within the organization and that communication takes place regarding the effectiveness
of the quality management system.
Resource management includes provision of resources, human resources infrastructure,
work environment.
For example, in work environment part, East Asia determined and managed the work
environment needed to be achieve conformity to product requirements
Product realization includes planning of product realization, determination of requirements
related to the product, Design and development planning Purchasing Production and service
provision
For example, in purchasing part, the company ensured that purchased product conforms to
specified purchase requirements. East Asia can supply all of requirement about product
from specific customer, that’s why they become to be stronger over time.
Measurement, analysis and improvement include monitoring and measurement Control of
nonconforming product, analysis of data and improvement. For example, in analysis of data
part, East Asia determined, collected and analyzed appropriate data to demonstrate the
suitability and effectiveness of the quality management system and to evaluate where
continual improvement of the effectiveness of the quality management system can be made.
Here all contents to answer the question how East Asia company can apply ISO 9000, but
there another way to us to understand easily by and answer some question when we look at
their operation as follow:
Effective operation
The rule set to make company better
Following the fixed rules in this company
What is their innovation?
Operations Management Report
Page 4
At the end, the manger of East Asia said that their innovation is ISO14000 in the near future.
IV. PROCESS STRATEGY
1. GENERAL
The production line is WETLUX technology. The factory has prepared to build a new
production line with NOF technology. Productivity: 5000-6000 ton/month (the ratio is 80%
Zinc plated Steel plate, 50% Color plated steel plate. Recently, the ratio is changed to 50%
plated Steel plate and 50% Color plated steel plate. And last month, the ratio of production
is that the percentage of color plated steel plate is more that one of zinc plated steel plate. )
Effective output is 30% or 40% of design capacity. Instruction includes 4 independent
production lines. Maybe the product of this production line becomes raw material for
another one (internal traffic)
2. DETAIL
A) GALVANIZED IRON
There are 8 sections in Zinc plated Steel plate production line
Step 1: Checking input Materials:
From production schedule, checking the specification of materials and define quantity.
Weighing the Black Sheet bundle, writing and recording the data such as: standard weight,
actual weight, suttle, specification and mode into the quality logbook of Black Sheet.
Checking the quality:
Round check: specification, place of origin
Unpacking the bag, checking inside materials. To some bundles which are not enough
equality such as : distorted, exothermic, iron-mould ….they will be carried out without
producing.
In the production process, workers often monitor the quality of Black Sheet (level of fertile,
exothermic, rupture…) then record in the quality logbook of Black Sheet.
Operations Management Report

Checking input Materials
Direct feed material continuously
Remove lubricant or rust
Deoiling and Pickling
Heating the sheet
Plating ZINC
Cooling
Passivation surface
Package and storage
Step 2: Direct feed material continuously:
If the materials are enough quality to produce, they are inflow exhaust
system and hood up with the first bundle to provide continuously for
production line
Step 3: Deoiling and Pickling:
Before Steel plates was entering to plate, they had had to through the
deoling and pickling section, this section has 4 parts :
Using chemicals to deoil :
First, the Sheet band must go through the cistern concentration from 23
to 40, the temperature is 600C – 800C here with steam, then next to two
flushing chambers. Those flushing chambers is including : pump high –
pressure team system and small detergent from the cistern. It atomizes
two faces of black sheet bundle; use the crane to cleanse deoiling parts.
It continues going through the hot water flushing chamber (600C – 800C)
to reclean some dirty elements on Sheet.
After that, sheets are gone into HCl bath with 10% - 20% strength. This is
checked twice per turn ad record in the quality logbook
The last part is a water bath to make HCl out, and Sheets go through the
hot water flushing chamber again. Then they are dried by a couple of
rubber crane before come to next section.
Step 4: Heating the sheet before coming Pan:
This process makes the temperature of black sheet bundles go to 2000C.
Operations Management Report
Page 6
Step 5: The process of plating ZINC:
With the temperature of 1800C – 2000C, sheets is entered soldering
flux chamber (Ammonium Chloride, antimony, aluminum) to flush,
increase the brightness and mechanical behavior of materials…
Then, sheets are gone through zinc chamber, second to radiator
grouping to finish this process.
Step 6: The process of Cooling:
The air duct system and booster perform this process. But after
cooling sheets with air duct system, the temperature of sheets still
are high. So they is bathed with a water chamber, here the
temperature is slow down 600C-800C. And the water chamber
makes sheets clear more.
Step 7: Surface Passivation:
Here, sheets are dipped in chromium chamber with the 3 – 7
strength and the temperature is 550C-600C. Sheets are overlapped
by a protective coating chromium against to pickling. Then they are
dried by a couple of rubber crane before come to next section.
Step 8: Packaging and Inventory:
Steel plates are categorized with the level of A, B, C of management
department. After making steel plates become bundles, they are
weighed, labeled and move to inventory. Some bundles which are
not quality enough, are taken out and recorded in the document.

B) PRE-PAINTED GALVANIZED IRON
Color plated steel plate product process divided into 4 areas by its function
Step 1: Input area
Raw sheets feed consecutive into manufacturing process, choose good material to
manufacture the best quality product
Black sheet bundle or zinc plated sheet plate which was be warm up and checked
carefully, will be choose to be material for Color plated steel plate product.
Material feed into input area by a couple of rubber crane and carry on carriage
To prepare for feeding raw sheets tin into manufacturing , material bring in drum to
decompress raw sheets by carriage
After bringing in drum to decompress raw sheets, hydraulic system decompress tang
, brace the core of raw sheets and move them into the center of route. Some devices
is such as junctors, sheets reserves place by Korea technology to ensure route will be
consecutive from input to output
Step 2: Cleanse area

Cleaning oil, dust on sheets to make higher adhesive strength of
coat on tin interface.
Cleanse area includes one clear oil bath with an injection blow
molding system; inject hot Alkali solution into both 2 surface of
tin. Then sheets were reamed by crane system ( imported from
Korea) to clean oil and dust which adhere on tin interface ( Notes:
if tin material still have oil or dust on its surface, so coat will be
appear easy….) oil in the clear oil bath will be recycle and check
carefully before exhaust outside. After clear oil bath are 2 hot and
cold flushing water bath, injection system, squeeze crane. To clear
chemical drains from clear oil bath and squeeze tin conveyor
careful when it exit from clear baths
Step 3: Coating ,baking, cooling
Coating, baking and cooling area or center area are some main
parts of tin plate route in order to output products
Center area include 3 lacquering machine (imported from Korea)
after lacquering machines are drying ovens which laboratory heat
could be more than 600oC
a. Lacquering machine: 2 coat axis technology, coating 2
surfaces in parallel. The axes are driven by AC vector motor
which purpose is to cover coat interface by a chromate
solution cover. This solution is a good protection from
corrosion and it is also play a role like a bonding layer to
adhesive other coats
b. After lacquering machines are baking ovens; baking oven
with the firing system import from German, using LGP to
bake the chemical surface and help it adhere on base metal

c. After baking oven is air-blast system with high capacity to
cool tin surface before feed into other lacquering
machines
d. Rough lacquering machine: 2 coat axis technology,
coating 2 surfaces in parallel. The axes are driven by AC
vector to adjust the thickness of lacquer film by driving
engine, infinitely variable control and modern load cell
system. Lacquer using here is lacquer base chromate,
import from well know trade mark like Becker, KCC,
Duracoat - help to protect from corrosion it is also play a
role like a bonding layer to adhere between tin surface
and lacquer coat
e. After coating a rough lacquer, tin bring in baking process
by using baking ovens in order to the lacquer cell stick
together and produce a strong adhesive lacquer. High
temperature baking oven system use LPG fuel with the
burner from German , Italia, help to avoid produce carbon
black which will affect the quality of product.
f. After baking, sheets will be cooled by high capacity air-
blast system and water spray system.
g. Fine lacquering machine: lacquer used here is lacquer
base Polyester - import from well know trade mart like
Becker, KCC, and Duracoat…. Using three - axial
lacquering in order to produce a glossy surface,
uniformity on whole surface (using to high quality
domestic product such as washing machine' shell,
refrigerator’s shell….), coat 2 surface in parallel which The
axis are driven by AC vector motor which purpose to
adjust lacquer film density until 25mm easily by driving

engine, infinitely variable control and modern load cell system. Lacquer film cover
uniformly on whole surface, help tin increase color fastness from severe weather
condition in our country and protect from Corrosion, commit to coastal area and
industry zone…
h. After coating the last lacquer film, sheets will bring in the baking process by using
baking ovens in order to the lacquer cell stick together and produce a strong
adhesive lacquer. High temperature baking oven system use LPG fuel with the burner
from German, Italia, help to avoid produce exhaust fume into natural. Heating
system from German, Italia burned almost fuel in order to avoid produce carbon
black.
i. After baking, sheets will be cooled by high capacity air-blast system and water spray
system.
j. After exit from the last water spray system, sheets cooled by high-pressure fan
system and became final product.
Step 4: Output area
a) Main function test product quality, divide raw sheets into parts like customer's order
form.
b) After sheets type exit from center area, it is driven by AC vector motor into looper in
order to the central part run stably and consecutively in scroll product process.
c) After testing by eye on both 2 surface, sheets is printed meter number and logo like
customer requirement and scroll by ripe.
d) After testing enough meter quantity sheets is cut, carry on carriage, packaged and
moved to finished products store.

V. LOCATION
POSITION
East Asia Co., Ltd was established in late of 1998 and officially went into operation in the
beginning of 1999. The main factory is located at Street 5, Song Than Industrial Park – Binh
Duong province with an area of over 30,000m2 that is one of the biggest industrial Zone in
Vietnam.
Song Than Industrial Zone
Lying in the heart of the Southern key economic zone (i.e, Ho Chi Minh City, Binh Duong,
Dong Nai, Ba Ria – Vung Tau, Tay Ninh, Long An, and Binh Phuoc) Situated near the main
route of the National Highway No. 13 with a system of the complete infrastructure
connected to the significantly principal routes of the national highway and the nationwide
commercial and economic centers.
The very advantageous geographical location:

o Although this location have a lot of competitor such as Hoa Sen Group but
market stills attract and potential in long time for them.
VI. LAYOUT STRATEGY
Today, the East Asia used product-oriented layout for production because characteristics of
each products. Factory has six departments in which have two Galvanized Iron worksation
and one Pre-painted Galvanized Iron workstation. Next year, Factory will have more one
Galvalume (Zacs) workstation.
There are six departments of factory
1. Operation Management Centre
2. Supply material
3. Workstation 1 produces Galvanized Iron
4. Workstation 2 produces Galvanized Iron
5. Workstation 3: Pre-painted Galvanized Iron
6. Inventory
Product-oriented layout had been used because factory makes focus only two kinds of
product that they need production is stable and high efficiency.
Operations Management Report
Page 14
Advantages and disadvantages of this layout
The product manager said that factory faced with area problem and they can’t expand area
of factory. Supply material area and inventory is often in minimizing stable that mean
company expense more money. Area problem is also reason that the distance between
departments is still so far and movement components still not convenient. For instance in
case, in workstation 1, finished product must bypassed new-come to inventory.
Although factory has many difficult but East Asia intend to make innovation of layout
so that production is more efficiently and reduce cost.
VII. HUMAN RESOURCE AND JOB DESIGN
The Human Resource strategy of East Asia based on the Annual Strategy of the company –
when the company defines its main strategy for the year – they will define the number they
want to have in their human resource based on all of the related sides: Marketing,
productivity …. After that, a process is opened up, they will search to the application pool in
some public places like job fair, the job centre…, then they will get the application, after
screening the application, the second round is the interview round. The interview round will
also be the last round of the selection process of East Asia. All of their process about Human
Resource, not only selection, but also others like training, incentive program … followed the
government process.
Product-oriented Layout
Advantages
•Low variable cost per unit
•Low material handling costs
•Reduced work-in-process inventories
•Easier training and supervision
•Rapid throughput
DisadvantagesHigher capital investment
•Special equipment
•Any work stoppage stops whole process
•Lack of flexibility
•Volume
•Product
Operations Management Report
Page 15
For training, they have 2 levels, the first one for low-level employees; mainly they will do
training on the job, and the former train to their new members, or their successors. This
kind of training is suitable for East Asia as the low level because it can save the cost, also
reduce the training time. Mainly the low-level employees of East Asia have low educational
level, with not high salary, and do simple processes work in the machine. With high level
employees, mainly high-level educational level, from business field or technical, East Asia
have programs for them to educate them more about knowledge and train more skills
needed. Sometimes, they send some of their technical employees to near country like
Singapore and Malaysia to learn more about the modern techniques in this country.
East Asia follow the Employment-stability process, that keep their employees constant with
time, and expand their employees by around 10-20% per year. Their Standard work
schedule is 3 periods (8 hours per one period) per day (24 hours per 24 hours), with this
working time, they can produce with all of natural providing time and take advantage of the
running of machine to keep the work all the time. The working rules of East Asia are clarify
and put in the information board of each machine – then the employees can follow their
period and do needed things with respect the rules to make the process run well time by
time. They have 3 types of machine, produce differently, around 7 to 10 to 20 employees
per machine, depended on the complex level of the work.
The work in East Asia, as watched, can be clarified to 2 types, high-level and low-level. In
Low level, they do the work with very high specialization – the low-level employees work in
process together with the machine, their works require very accurately and somehow
simple, that why their employees don’t need to have average education level. With high
level, they work as administrative works and high level techniques and business, still with
specialization but more autonomy than low-level, their education and training are also
better.
The psychology components of job design for low-level employees are rather clear. Skills
variety is not so much because the job is specialization. The job identify is clear, also
trained carefully on the job. Job significance is also clear, each employee has his
Operations Management Report
Page 16
responsible, and stated clearly in the information board, working rules, and process
identification. Job autonomy and feedback on the job is not much, due to the job
characteristics.
Motivation system of East Asia is based on productivity and some gain sharing and profit
sharing of the company. The ergonomics and work method in East Asia is also rather good.
Their process is semi-autonomic, the employees just special in their works beside the
machine. Work environment in East Asia is somehow rather good, with wide and high
factory. But the noise in the machine is so high, very head-ache sound. The dust from the
machine is not so much due to the good technology of East Asia, it’s a plus signal for work
environment.
C. PART III: MANAGEMENT OPERATIONS
VIII. INVENTORY MANAGEMENT AND SUPPLY CHAIN MANAGEMENT
Inventory is a very important part of any company and so does East Asia Company. It helps
the company flexible to keep pace with customers’ needs and perform production process
effectively. In this part, East Asia Company’s inventory is discovered in main terms below.
The method used to compute the inventory level that the company apply is base on
production volume, sale volume and inventory capacity. After all factors are balanced, the
backward calculation is done to find out the amount to keep in inventory.
The goals are to minimize the cost and satisfy the demand such as reduce holding cost – the
cost of carrying inventory over time. The company tries to get stock safety and avoid stock
outs. The company invests a lot in equipment and management tools. The setup cost is
high. Once a year, each chain of production equipment is repaired and maintained for one
month according to ISO 9001-2000 quality management standard.
Record and cycle account: Each roll of material or product is verified carefully and pasted a
certification sheet of characteristics and codes to manage. The manager goes around
checking and recording them. Management the inventory is done by software. The company
has invested in Lac Viet software company 300 million vnđ for operation management
software.
Reorder: the company order in two sources: domestic suppliers (30% raw material demand)
and foreign suppliers (70% raw material demand). Domestic company is Phu My steel
company. This company uses Italian technology, so that their products have high quality,
Operations Management Report
Page 17
short lead time but low quantity outputs. And the price is published daily. The commercial
department has authority and responsibility to make decision on order (which companies
are suppliers for each period for reorder point and order detail)
IX. MATERIAL REQUIREMENT PLANNING AND ERP
At the present time, East Asian doesn’t have MRP or ERP computer system. In short term,
East Asia will use MRP software of Lac Viet Co., Ltd for management system
X. SHORT-TERM SCHEDULING
As we know the important role of scheduling in an organization as the competitive
advantage of this institution from faster movement of goods through a facility, faster
deliveries, and reliable deliveries.
In East Asia Company, scheduling also play an important role like that. For the fixed
scheduling with auto-machines, scheduling is assigned correspondingly from each worker
group to each task with a specific machine in continuous production. Basing on the demand
or requirement form the market, the manger can give out the requirement of output for
each period, so that, for each period the scheduling should be changed, and worker is
ranged in the most suitable position of time and task. It is very effective because it does not
make worker bored, they are more willing to work in different tasks and different time.
XI. FORECASTING
Base on the development of Vietnamese economic (GDP, population), the department of
marketing will forecast the future plan on October and November for the next year.
As the development of the company, East Asia co., Ltd will invest on new equipment,
maintenance-process … with high quality, and update the management program
continuously
D. CONCLUSION
East Asia co., Ltd is one of the 500 largest private companies in Viet Nam, qualified as ISO
9001:2000 about product.
The current volume of products has not met the large demand for steel in Viet Nam. So, with
the proud of customer satisfaction about its high quality products, East Asia Co., Ltd will
enlarge production as well as the size of company more and more in the future.
