Today's manufacturers must respond quickly to customer needs. In particular, make-to-order companies are constantly striving to satisfy customer demand for products in order to secure more favorable conditions in the future through bidding. In this bidding process, quotations play a very important role in providing favorable conditions. And the most important content that companies strive to satisfy their customers is the product's performance. Therefore, a company can attract customers and secure economic profits through good quotations, but it can be said that the first priority is to match the performance of the products requested by the customers. That is, when a company creates a quotation, it is important to structure the quotation according to the performance of the product. Thus, this paper intends to present a quotation management framework and a quotation BOM information model for constructing quotations efficiently in make-to-order manufacturing. And, in order to prove the usefulness of the proposed quotation management framework, we presents an case of the construction of an quotation management system based on the JAVA platform. As a result, the integrated quotation management system based on the proposed quotation management framework and quotation BOM has been successfully operated in a make-to-order company that manufactures marine engines.

In this paper, we conducted a study to understand the impacts of safety behavior, safety and health delivery and communication, which should be managed for the establishments' safety and health control on occupational safety and health policy satisfaction to utilize that as a material for preparing policy support and preventive measures. For this purpose, we conducted a statistic analysis with 2,970 establishments, utilizing the material, "2015 Occupational Safety and Health Company Survey". As a result, in the manufacturing industry, it turned out in the establishments with more than 300 workers, safety behavior, safety and health delivery and communication of the cooperative firm of the prime contractor were high. In addition, it turned out that safety behaviors had the biggest impact on occupational safety and health policy satisfaction in the manufacturing industry and safety and health delivery and communication had the biggest impact on occupational safety and health policy satisfaction in the construction industry and other industries. As for the relationship between companies, it turned out that safety behaviors had the biggest impact on that between the parent company and a cooperative firm of a prime contractor while safety and health delivery and communication on that between the prime contractor and the subcontractor. Through the results of this study, it is necessary to build up safety and health behavior and safety and health delivery and communication systems for the characteristics of the company, and it is expected that the effect of the safety and health control will increase when policy support is made accordingly.

Cyclonite is a white powder and is very explosive. It can cause seizures (a problem of the nervous system) in human and animals when large amounts are inhaled or eaten. Research papers for workers exposure assesment of the cyclonite are very a few in the world. A field study was conducted at explosive compounds and bomb manufacturing companies to evaluate workers exposure to cyclonite. The airborne average concentration of cyclonite in explosive compounds manufacturing company was $4.10{\mu}g/m^3$(range: ND - $59.92{\mu}g/m^3$), and that of cyclonite in bomb manufacturing company was $31.49{\mu}g/m^3$(range: ND - $291.41{\mu}g/m^3$). Package process and assembly process in both companies were considered the high potential of exposure to cyclonite. Even though all airborne concentrations of cyclonite were lower than occupational exposure standard (MOEL: $500{\mu}g/m^3$), exposure to cyclonite can also occur through dermal contact during manufacture, handling, and clean-up of cyclonite. So control measures for protecting skin absorption of cyclonite were needed for preventing adverse health effect by cyclonite exposure.

In accordance with the trend for cooperation of related company, BOM (Bill of Materials) has become an important factor in the manufacturing of production. BOM manages a various basic information of design, production, and process and so on. Especially, automobile industries are related to many company, they build a cooperative system from the communication of information. In this study, we have analyzed a BOM structure of a well-used automobile part industry and proposed a structure of engineering BOM, manufacturing BOM, process BOM for cooperative environment. A proposed various BOM structure are flexible in responding to the situation of structure alternations for automobile part. And also they include in environment factors. It is expected that these BOM structure will be used to basic template in automobile part industry which could be loaded with cooperative hub-system.

Nowadays, customer-oriented manufacturing enterprises such as airplane, ship, ship engine, etc are knowledge-intensive and higher added value industries. In these companies, to quickly respond customer's order, a quotation management is a very important task. But, this task is very complex, time-consuming, resource- consuming, and difficult process because it is related with many departments within a company. In this paper, for the effective and efficient quotation management, the concept of product specification framework is introduced because a quotation BOM (bills of material) can be created from product specification. Also, this paper presents the product specification framework based quotation management process and implements the quotation management system for the ship engine division of 'H' company, one of customer-oriented manufacturing enterprises. As a result, the proposed quotation management concept reduced a lead time of drawing out quotations from $3{\sim}10$ days to 1 hour. And, the constructed quotation management system achieved a rapidity, accuracy, quality, and workload reduction of the quotation management process.

자동차산업은 높은 수준의 전문화, 많은 생산량과 같은 특징을 가진 진입장벽이 높은 산업중 하나이다. 자동차 제조기업의 물류아웃소싱은 여러 회사에 아웃소싱을 주기보다는 특정 물류 서비스에 대해 독점 제공업자와 장기계약을 체결하거나, 한 개 이상의 물류서비스제공업자에게 물류의 특정영역 혹은 전부를 맡기는 계약을 체결하기도 한다. 본 연구의 목적은 서로 다른 물류아웃소싱 전략을 활용하고 있는 자동차 제조기업의 특성에 대한 분석을 통해 자동차 제조기업의 물류아웃소싱 유형별 특징을 도출하고, 장 단점을 비교하여 시사점을 제시하는 데 있다. 특히 우리나라 현대-기아차의 물류를 담당하고 있는 현대글로비스 사례를 중심으로 물류혁신과 효율적인 물류서비스 제공이 글로벌 공급사슬통합에 어떠한 효과를 미치는지에 대해 분석하였다.

In this study, we developed an allocation optimization system for supply chain management in the shipbuilding and offshore construction industry. Supply chain operation is a way of operating manufacturing company responsible for the procurement of outfitting parts. The method about how to allocate the manufacturing volume to each partner company includes important decisions. According to the allocation method, the stability of the material supplied to the final installation process is guaranteed. We improved the allocation method that was previously decided by the person in charge. Based on the optimization engine, a system is developed that can automatically allocate the production volume. For optimization model configuration, factors affecting the volume allocation were analyzed and modeled as constraint factors. A target function is defined to minimize the difference in the load variance of each partner company. In order to use the same type of volume allocation engine for various outfitting products, the amount of work done by the partner company was standardized. We developed an engine that can allocate the same production load of each production partner. Using this engine, the operating system was developed and applied to the actual offshore project. It has been confirmed that the work load variance of suppliers can be maintained uniformly using the optimization engine rather than manual method. By this system, we stabilize the manufacturing process of partner suppliers.

In an environment where manufacturing conditions such as product lines keep changing, manufacturing control systems need to be continually maintained and upgraded according to the change. This requires an effective system implementation methodology. In this paper, a methodology based on the multi-criteria similarity comparison of manufacturing processes is proposed. A newly introduced process is compared with existing ones based on the multi-criteria similarity, and candidates for software reuse are selected from stored modules according to the overall process characteristics. The proposed methodology has been tested for an electronics manufacturing company's manufacturing control system, and the result has been satisfactory in that it can save time and efforts for system implementation.
