Soongoo Hong,Narang Kim,Seongbae Lim 한국인터넷전자상거래학회 2015 인터넷전자상거래연구 Vol.15 No.5

Many small and medium-sized manufacturing enterprises(SMMEs) have introduced and operated Production Information Systems(PISs). While previous studies evaluated performance immediately before and after system implementation, few investigated the operational performance of PIS, which focuses on the performance over a given period after system implementation. This study analyzes the differences between performance immediately after system implementation(establish and stabilization period) and the performance after a given period of time(operational phase). It also investigates factors that positively influence operational performance. The results showed that downtime decreased more in the operational phase than in the establishment and stabilization phases. In addition, the CEO’s support, user training, system improvement and maintenance, and the expertise and interest of the person in charge of a system were all identified as critical success factors influencing the operational performance of PISs.

성장 잠재력에도 불구하고 많은 B2B 시장은 참여업체 수의 부족으로 운영의 어려움을 겪고 있다. 따라서 어떠한 방법을 통해 충분한 숫자의 기업들을 시장에 참여하도록 유도할 것인가가 B2B 시장의 성공을 위한 주요 요인 중의 하나로 인식되고 있다. 본 논문은 MRO 시장을 대상으로 공급업체들을 구매자 중심의 전용시장(Private Exchanges)에 참여하게 만드는 요인들이 어떤 것인지를 규명해 보는 것을 주요 목적으로 하고 있다. 이를 위해 EDI 채택에 관한 선행연구와 실무자들과의 면접에 기초하여 실험대상 요인들을 추출하였다. 불완전한 계약 이론(Incomplete contract theory)에 기초하여 가설의 설정과 검증을 하였으며, 분석 결과 시장에 참여할 것으로 기대되는 공급업자들의 수와 시장 참여의 대가로 주어질 보상의 유무가 B2B시장의 참여에 긍정적인 영향을 주는 요인으로 나타났다. 한편 구매업자에 대한 신뢰는 유의한 요인으로 드러나지 않아 공급업자들은 기존의 구매업자와의 신뢰관계가 B2B 시장에서는 중요하지 않는 것으로 조사되었다. Many B2B electronic markets (EMs) are struggling to survive because they failed to attract enough participants. Thus reaching critical mass of participants is one of the key success factors for various types of EMs. The main purpose of this study is to investigate factors that lead MRO (maintenance, repair, and operating) suppliers to participate in private exchanges (PE), the buy-side EM. This paper introduces the characteristics of the PE according to the classification schemes introduced in previous studies about EM types. Literature is reviewed on suppliers’ adoption of inter-organizational information systems focusing on EDI adoptions issues. Data analysis based on incomplete contract theory and the social exchange theory is then presented. The results of this study show that the number of suppliers and subsidy are factors that influence suppliers' participation in PEs. Nonsignificant results relating to trust imply that suppliers who are invited to participate in a PE do not expect their off-line relationships with the buyer to be transferred to the PE.

In manufacturing operations, oil plays a crucial role in reducing friction and wear among interacting surfaces at varying velocities, loads, and temperature. Hydrocarbon oil is considered the origin of lubrication oils. However, this base oil has been limited in its use as it is a principal cause of pollution. This research focuses on identifying a biodegradable base oil lubricant that possesses a stable coefficient of friction and viscosity with temperature. Friction analysis is conducted by employing a pin on a disk tribotester with a fixed load of 10 N at varying sliding speeds ranging from 0.06 m/s to 0.34 m/s. Oil viscosity analysis is perfomed at room temperature by using a rotary viscometer. Tests are performed using canola oil and paraffin oil as lubricants. The results indicate that the viscosity of canola oil is more efficient than paraffin oil. The non-dimensional characteristic number according to the Stribeck curve reveals an elastohydrodynamic lubrication regime with canola oil lubrication. A comparison of both lubricants reveals that, the friction efficiency of canola oil and paraffin oil does not differ considerably. However, the friction in canola oil is observed to decrease more than that in paraffin oil at an elevated sliding speed. The tests confirm that canola oil is potent in minimizing the friction coefficient of SCM440 bodies interacting with one another as well as acted upon by load.
