In respond to the demand of an open, fair, transparent, and efficient environment for procurement, many governments have incorporated the use of internet in their procurement systems with online procurement (e-procurement). Given the different policies and laws which have to be complied with, the practice of government e-procurement system varies from one country to another. Thus, experiences in running e-procurement will vary as well. The achievements and obstacles of one country's experience will be a constructive reference for other countries in establishing e-procurement system. In this regard, government e-procurement system practices in two Southeast Asia countries i.e., Thailand and Indonesia particularly in public works are consecutively presented and finally compared in this paper. The government of Thailand has applied Online Auctions (e-Auctions) as the national procurement practice since 2005 and performed the e-Auctions in two types: Reverse Auction and Sealed Bid Auction. Contrary to the common practice of e-procurement, the Thai government, with some rationales, runs the bid documents obtaining manually as well as qualification and technical documents submission and holding the e-Auctions at bidding office. Whereas Indonesian government runs Online Sealed Bid Bidding (e-Procurement) and most of the bidding stages are performed electronically except bid evaluation for both technical and financial. The advantages and drawbacks of these two e-procurement practices are discussed as well as improvements that have to be made for successful of e-procurement.

최근 전자상거래가 활성화되고 국가 공공조달 분야 또한 전산화하면서 국가 공공조달을 위한 조달업체 관리 및 평가 시스템에 대한 필요성이 커지고 있다. 민간 기업들은 공급망 전반적인 프로세스를 자동화하고 외부 파트너인 공급사와의 관계를 전략적으로 평가 관리하여 공급망 전체 효율을 높이고자 SRM(supplier relationship management) 시스템을 구축운영하고 있다. 최근 조달청은 국가 공공 조달의 경쟁력을 강화하고 공공조달의 공정성을 확보하고자 SRM 개념을 도입하고 있다. 이를 위해 조달업체 평가 관리와 수요기관이 투명한 조달업체 선정을 할 수 있도록 하는 구매의사결정 지원 프로세스 수립이 필요하다. 본 논문에서는 민간 기업에서 활용하고 있는 SRM 시스템을 공공조달에 적용하여, 공정하고 객관적인 공공조달을 위해 조달업체 평가에 필요한 평가지표와 평가모델을 제시하고 이를 공공조달에서 전략적으로 활용하는 방안을 제시한다.

In the EPC(Engineering Procurement and Construction) project of the plant, procurement engineering has a profound effect on the profitability of the project. It is important that the procurement specifications are well written to ensure that procurement engineering works properly. In the meantime, the procurement specifications have been created by the experience of the person in charge because there was no system for helping procurement engineering. To cope with this situation, we are developing a procurement engineering management support system (PeMSS). This paper describes how to implement a knowledge-based service in the procurement engineering management support system. First, we briefly introduce the PeMSS, the knowledge base application field, and how to apply it. The parts that requires knowledge-based service are parsing the requirements in the PDF (Portable Document Format) file and management of the document provided by the supplier of the equipment.

In the plant industry, the share of equipment accounts for 45 ~ 75%, which is very high. It is a traditional plant centered on processes and reactions like petroleum and chemical plants. Renewable energy generation plants such as wind power generation and solar power generation are equipment-centric plants. Equipment-centric plants are very important not only in the EPC phase but also in the operation and management phase. The procurement of equipment for plant operation and management can be divided into make and buy. Make is a method of producing equipment itself, and buy is a method of procuring equipment from the outside. The procurement method of the equipment directly affects the plant operation and management cost. In this study, the decision making of equipment procurement method for plant operation and management is defined as 4 phase. Each phase is selection of procurement decision-making objects, technology strategy perspective, finance perspective, and production perspective. In detail, we defined selection process of procurement decision-making objects and technology strategy perspective process. We will contribute to the enhancement of the competitiveness of the plant operation and management area by carrying out researches on the process and application examples of financial and production perspectives in the future.

The standardization of food ingredients in the procurement system is essential to maintain the quality of food services. Currently, school food services in Korea do not have such a standardized system, which results in inconsistency of the procurement procedure of food ingredients. This study examined how school foodservice nutritionists perceive the standardization of food ingredients in the procurement system. In particular, this study investigated school foodservice nutritionists' perception on the appropriateness, convenience, and necessity of newly proposed standardized procurement system consisting of a classification and attribute system. A total of 311 nutritionists from 123 elementary schools, 99 middle schools, and 84 high schools were surveyed via both online and offline from June 16-24, 2016. The major findings of the study are as follows. First, three quarters of the nutritionists perceived the newly proposed standardized procurement system to be necessary, while approximately sixty percent of the respondents reported that the newly proposed standardized procurement system is convenient. More than half of the respondents perceived the newly proposed standardized procurement system to be appropriate. The results suggest that the new standardized system directs a better way in terms of the classification and attribute systems of food ingredients. This study suggests that the standardization of food ingredients should be implemented at the operation of school food services.
