| dc.description.abstract | Procurement is one of the most important roles in the supply chain. It impacts a lot in
the successful of company. Moreover, one of the criteria which will decide the success
of the beginning of the chain is selecting suppliers. To select suppliers, especially
sustainable suppliers, it will take a lot of time and effort. Because, to choose the correct
sustainable supplier, it depends on many crucial criteria. In this thesis, the study will be
focused initially on ranking and summarizing to find the best suppliers from the
collected data, then comparing two methods to find out the different from the results and
their own advantages and disadvantages. There are 100 people from many fields (80%
in steel industry, 20% in different majors) conduct the survey so that the data of the
importance criterion is collected. Then, the ranking of three suppliers in mainframe
fabrication is implemented by BOD, Supervisor Purchasing, and Quality Control Leader
in Universal Vietnam Steel Buildings. In this ranking, the data should be collected from
the experts who have worked with these suppliers and it is the private data as well. One
of the methods that be used in common to select supplier is Multiple Criteria Decision
Making. The Analytical Hierarchy Process (AHP), Best Worst Method (BWM), and
Technique for Order Preference by Similarity to an Ideal Solution (TOPSIS) will be
applied to choose the supplier. In this study, there are three main criteria, included:
Economic, Social, and Environment. There will be three key point for picking supplier.
Besides that, in each main criterion will have some sub criteria which is separated
carefully into many perspectives of selecting suppliers. More specifically, “Economic”
will include Cost, Quality, Payment Term, Flexibility, and Time. “Social” has Location,
Customer Satisfaction, Safety Systems & Occupational Health, and Transparency in Accounting and Business. “Environment” will have Pollution Control, and Waste
Treatment. In this study, each criterion will be compared together in order to ranking the
importance of each criterion when selecting supplier by survey of 100 people from
different fields. The survey performs the different view of criteria on selecting suppliers.
After that, the average score of each column of the survey data will be calculated to
choose the final score of each criterion. The private data of each supplier will be
collected from Universal Steel Buildings will use to ranking the supplier to check the
accuracy of MCDM and the real choice. Combining three methods which are listed
above to implement the AHP-TOPSIS, and BW-TOPSIS. So that, the view of selecting
suppliers will be larger. From that, the comparison between them will be made in order
to choose the best way to select supplier. The result of two methods is the same, but
AHP-TOPSIS, and BW-TOPSIS Methods have their own advantages and
disadvantages. | en_US |
