세계 10대 도시이며 Metro City인 서울특별시는 인쇄, 봉제, 기계금속 등 전통적인 도심제조업이 분포되어있다. 이들 제조업은 세부 업종 및 공정에 따라 소상공인 집적지를 형성해 서로 상부상조 하는 형태로 발전해왔다. 집적지의 특성상 집적지 내 각 공정별 업체 간 물류는 신속히 이루어지고 있으나 상대적으로 영세한 소상공인이 최종 단계의 완제품 수요자에 대한 주문처리 서비스를 준비하기에는 어려운 현실이다. 따라서 원활한 수주, 배송처리를 위해 집적지 상공인을 위한 통합수주 Fulfillment Service Platform 도입이 시급하다. 본 논문에서는 전통 도심산업 중 인쇄업 소상공인의 기존 Fulfillment Service data를 수집, 분석하고 CRNN, k-NN, ID3 Decision Tree algorithm을 적용한 인공지능 Fulfillment Service Platform 시스템을 설계한다. 본 연구를 통하여 집적지 소상공인 누구나 활용할 수 있는 개별 수주, 배송 맞춤서비스 사용이 가능하게 함으로써 소상공인 매출 증대 및 역량 향상에 크게 기여할 것으로 기대한다.

본 연구에서는 스무딩된 주문정책이 리드타임, 만족율, 재고비용에 미치는 영향을 연구한다. 이를 위해 스무딩된 order up to 주문정책을 사용하는 하류업체와 make to order 방식을 사용하는 상류업체로 구성된 공급사슬을 사용한다. 스무딩을 하면 리드타임이 예상하는 바와 같이 감소된다. 그러나 스무딩에 의해 하류업체에서의 만족율이 감소하며 재고비용이 증가된다. 한편 상류업체 제조시간의 분산이 평균 제조시간보다 만족율 및 재고비용에 미치는 영향이 더 크므로, 상류업체 제조시간의 변동성을 최소화해야 한다.

In the rapidly propagating Internet based electronic transaction environment. the importance of real time order confirmation has been more emphasized, In this paper, using data mining techniques, we develop intelligent operations decision model to allow real time order confirmation at the time the customer places an order with required delivery terms. Among various operation plannings used for order fulfillment. mill routing is the first interface decision point to link the order receiving at the marketing with the production planning for order fulfillment. Though linear programming based mathematical optimization techniques are mostly used for mill routing problems, some early orders should wait until sufficient orders are gathered for optimization. And that could effect longer order fulfillment lead-time, and prevent instant order confirmation of delivery terms. To cope with this problem, we provide the intelligent decision model to allow instant order based mill routing decisions. Data mining techniques of decision trees and neural networks. which are more popular in marketing and financial applications, are used to develop the model. Through diverse computational trials with the industrial data from the steel company. we have reported that the performance of the proposed approach is effective compared to the present heuristic only mill routing results. Various issues of data mining techniques application to the mill routing problems having linear programming characteristics are also discussed.

This study proposes a collaboration system framework on the web service in a supply chain to implement an efficient virtual supply chain and improve an ability to fulfill received orders over a supply chain. The system based on the framework proposed in this paper plays an important role for automatic order negotiation and placing/receiving an order noticed in web service by the main system. Furthermore, it can evaluate the fulfillment of received orders over a supply chain by using the transaction results from hierarchically related vendors and establish efficient manufacturing plans. In a word, this system is the automated system for creating manufacturing plans, placing and receiving orders. A little more important main function of this system is that it has a dynamic evaluation capability about fulfillment with received orders over a supply chain, and improves the evaluation method of fulfillment ability with received orders with related to direct dealing vendors, which is a main problem in existing system. As a result, this system is able to reduce the work load of the sales and purchasing materials, production control division, to manage accurate inventory promptly, to maintain the optimal inventory level by analyzing the information of fulfillment ability with received orders, and to enhance the level of service for customers.

In the current global business environment, it is very important how to allocate products from the producer to buyers (or distributors). Sometimes some buyers can order more than pertinent demand due to inappropriate forecasting customers' orders. This is the big obstacle to the efficient allocation of products. If the producer can become aware of buyers' pertinent demand, it is possible to realize the high-level order fulfillment through the effective allocation of products. In this study, a new allocation policy is proposed considering buyers' demands. The backpropagation algorithm, one of algorithms in neural network theory, is used to find pertinent demands from the distributors' orders. In the experiment, an allocation policy considering buyers' demands outperforms previous allocation policies.

The purpose of this research was to find out plans to promote the fulfillment of the breast self-examination and breast cancer screening, which is preventive health behavior about women's having breast cancer exam in some part of our country with searching for the primary causes which have an effect on their fulfillment. The subjects of the study were 540 literate volunteers who were of age from 20 to 69 and who visited 8 health centers in Taegu. The survey research was made through questionares in the 8 health centers in Taegu from the 15th to the 30th of September, 1998. Based on Becker's health belief model asking medical staff's opinions with bibliographies, the major findings from the survey was as follow. The fulfillment rate of the breast self-examination and the breast cancer screening was 37.8％(204 subjects), 27.6％ (149 subjects) each. Getting breast self-exam varied significantly depending on subject's age, income of family, religion, occupation and the number of children. As far as the breast cancer screening was concerned, there was remarkably significant difference in accordance with their age, marital status, religion, occupation, income of family, the number of children, ways of nursing and parturition age of the first baby. The subjects in their forties accounted for the highest rate. Based on the fulfillment of the breast self-examination and the breast cancer screening, the average points of all the variables presented from the health belief as well as the points of the susceptibility, seriousness, benefits, knowledge and level of health concern of interest in health were significantly higher than the points of non-fulfillment of them in the statistical analysis whereas the barriers was lower than them. In consequence of the multiple-logistic regression analysis putting the breast self-examination and the breast cancer screening in dependent variables, occupation, knowledge, seriousness, benefits, barriers and cues to action had significant effects on breast self-examination against breast cancer. Looking more attainments, thinking diseases more seriously, feeling more usefulness and there being any patient around with breast cancer led to the higher rate of the breast self-examination against it. On the other hand, feeling more impedition as well as housewives caused the lower rate of it. The breast cancer screening was significantly affected by age, sensitivity, usefulness, impedition and behavior momentum as well. The cases who are older, feeling more sensitivity against breast cancer, more usefulness of the examination and where any patient around, the fulfillment rate was higher. Contrarily the more impedition they felt, the lower the fulfillment rate was. Accordingly, the study of the causes, which have significant effects on the fulfillment of the self-examination and the breast cancer screening in order to find it in an early stage, and the development of health education programs as well as proper education for public health through carrying on campaigns and stepping up public relations must be indispensable.
