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.

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.

In a make-to-order manufacturing environment, the manufacturer's quotation information is important information used as basic information for bidding, receiving orders, and producing products in response to various customer demands. This quotation information is changed according to various factors such as customer demands, changes in product production environment, changes in drawing information of technical partners, and technological improvement of products. Due to this change, various changes occur in the quotation information that the manufacturer is preparing to reflect the customer's requirements. The change of quotation information according to these various change factors puts a lot of burden on the quotation management work from the standpoint of a make-to-order manufacturing company. In particular, the change of quotation information due to the change factors of quotation is inevitable and frequently occurs due to the requirements of the customer in the customer-oriented make-to-order production environment. In this paper, we propose a quotation change process based on the quotation creation process and propose a consistent and efficient quotation change processing method. To this end, the factors causing the change of quotation were defined, and the types of changes for each factor were defined. And it shows the procedure of applying the quotation change process to the quotation management system through the cases of each cause of the quotation change. In addition, in order to show the usefulness of the quotation change factors, the type of quotation change, the quotation change process, and the quotation system management, the proposed quotation change process and function was applied in the integrated quotation management system for the ship engine division of a typical make-to-order manufacturing company 'H'. As a result, it was confirmed that the proposed quotation change process and management system according to the quotation change factors were efficiently performed.

The accurate quotation of Available-To-Promise (ATP) plays a very important role in enhancing customer satisfaction and fill rate maximization. However, the complexity of Supply Chain structure, which includes all the linkages among procurement, production, and distribution, makes the accurate quotation of ATP be a quite difficult job. This paper presents a computerized ATP quotation system in global SCM environments where the worldwide headquarter, distribution centers, and manufacturing facilities are globally networked. We modeled the ATP quotation processes with the definition of required data flow and a comprehensive ATP-algorithm was newly developed. The illustrative example shows the efficiency of the proposed system is largely affected by the selection of alternative rules used in ATP-algorithm.

After free trade, it is increasing to import crops, aquatic products, and livestock which are produce in a foreign land. But it is affect negatively to trust relationships and markets of Jeju's foods because of breaking it out that foreign productions exchange domestic. Therefore, this paper designed and implemented the Genuine Quotation system of Black pigs using UHF RFID. This system is developed for distinguishing spuriousness, then searching information of the product through EPC ONS in EPCIS to print within a screen. Moreover, this intuitional and efficient system is constructed by connecting various sensors and lights. It can be contributed income increase thorough the security for the quality authority of the agricultural & stockbreeding products with FCS, FCG Certificate and the genuine certificate of the black pig which is the one of most typical agricultural & stockbreeding products in the pure Green Province, Jeju.

At the point of changing from the capacity qualification of temporary equipments for building to safety certification system, the meaning of qualification and the present state of main products are evaluated for Capacity qualification system and compare with related system in developed country. These suggest classification of temporary equipments for building construction in safety certification. Now, present state of the capacity qualification system is estimated; according to the reforming system from restating law in 2003, there are a lot of changing of application in every 3 years because of that. The ability of Making business is improved by checking again but, there are limitation to constantly keep the safety as the system to approve form about sent imitation products. Changing from the capacity qualification system to safely certification system make to include the structure of the qualification system and make a plan standard. It make least panic in the building market and set up some standards for capacity by changing building circumstance. The classification of temporary equipment for building construction in safety certification from the module of quotation form classify each duty quotation item, self-regulation safely verification item and option quotation item, these will more improve the system form and quality of temporary equipment for building than before.

Today's competitive global market makes most enterprise endeavor to specialize their business areas, and co-operate with trading partners in supply chain by the forms of collaboration, information and business process sharing. However, even the supply chain plan generated by co-operation often fails to be executed successfully, because it was generated without capacities of suppliers and more over nested suppliers. To overcome this limitation, the supply chain plan of an enterprise should be generated truly integrated way. In this paper, we classify business patterns based on scenarios about quotation processing and supply chain planning in self-integrated environment. And we present business process models about four business patterns and describe them, which are classified by whether request for quotation includes information about price, required time periods, and quantity for each required time period and whether it is received from customer or sent to supplier. In addition, we describe the types of supply chain planning problem.
