It is very important to forecast demand and determine the optimal procurement quantities of spare parts. The Army has been forecasting demand not with actual usage of spare parts but with request quantities. However, the Army could not purchase all of forecasted demand quantities due to budget limit. Thus, the procurement quantities depend on the item managers' intuition and their meetings. The system currently used contains many problems. This study suggests a new determination procedure; 1) forecasting demand method based on actual usage, 2) determining procurement method through LP model with budge and other constraints. The newly determined quantities of spare parts is verified in the simulation model, that represents the real operational and maintenance situation to measure the operational availability. The result shows that the new forecasting method with actual usage improves the operational availability. Also, the procurement determination with LP improves the operational availability as well.

This study evaluated the importance of automobile procurement logistics using AHP. Although automobile procurement and logistics is represented by JIT, internal and external risk factors for the automobile and logistics industries are increasing, so it is necessary to re-evaluate them and establish countermeasures. Therefore, this study conducted AHP analysis targeting 30 automobile procurement and logistics experts. Through previous studies and interviews, 4 factors for Tier 1 and 12 factors for Tier 2 were derived. As a result of AHP, the logistics factor was analyzed as the most important and the cost factor was less important than the other factors. This means that supply chain operation is more important than cost, and it is analyzed that stopping all supply chain participants is more damaging than logistics or inventory costs. Such research can provide implications not only for the automotive supply chain but also other industries with similar characteristics, and it is considered to be a meaningful study at the present time when the global supply chain is being reorganized.

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.

This article analyzes the effects of regulation that restrict the conglomerate firms to participate in the public procurement of software. The regulation was implemented in 2013, and this article analyzes five years of firm performance before and after 2013 through DID (difference-in-difference method). In particular, this article analyzes how restrictions on conglomerate firms' participation in public software procurement affect middle and small firms performance. As a result, small-size firms achieve relatively positive results in private sector revenues compared to mid-size firms. However, there was no significant difference between the mid-size and small-size firms in profit margin. This study implies that the new policy is needed to improve the small and medium-size firms revenues on the private market by leveraging the public procurement market which restricted the conglomerate firms to participate. This can be done by complementing the regulation in line with servitization paradigm.

The G2B system is one of the important information systems in the e-government implementation. It is difficult to measure the cost reduction effect of the system introduction because there are many participants in the complex procurement processes. Previous approaches of the performance evaluation of such processes have been based on conducting some surveys and interviews with statistical methods. Therefore there have been some limitations in the verification of feasibility. Therefore this study tries to suggest a case of performance evaluation about the cost reduction in using of the G2B system by analyzing operational DB data from the G2B system. This study analyzed the procurement processes of G2B system according to 'goods' and 'facilities/services' and classified the procurement processes into 12 sub-processes. By developing an evaluation model for the cost reduction of e-procurement, we derived the whole cost reduction effect was 8,000 billon Won for the use of Korea KONEPS G2B system in 2008. Specially the cost reduction in the private sector was 6,600 billion Won. It was mainly due to the decrease of the offline visits to the related organizations to participate a bidding process. Moreover, the cost reduction of using shopping mall was 1,000 billion Won among the total 1,400 billion Won in the whole public sector. The main contribution of this paper is to show the more objective evaluation result of the use of e-procurement, which verifies the necessity of G2B system.
