오늘날의 기업은 상품을 판매하는 것 뿐만 아니라 기업의 신용과 이미지를 위해 그 상품에 대한 사후처리(After Service) 업무에 많은 투자를 하고 있다. 이러한 양질의 사후서비스를 고객에게 공급하기 위해서는 많은 인력을 합리적으로 관리해야 하며 요청되는 고장수리 서비스 업무의 신속한 해결을 위해 업무를 인력에게 합리적으로 배정을 해야 한다. 그러므로, 회사의 비용을 최소화하면서 정해진 시간에 요청된 작업을 처리하기 위해서는 인력들에게 작업을 배정하고 스케줄링하는 문제가 발생된다. 본 논문에서는 이러한 문제를 해결하기 위해서 화학계기의 A/S작업을 인력에게 합리적으로 배정 하는 스케줄링 시스템에 관한 연구이다. 먼저 스케줄링 모델을 HP사의 화학분석 및 시스템을 판매, 유지보수 해주는 Y사의 작업 스케줄을 분석하여 필요한 도메인과 고객서비스전략과 인력관리전략에서 제약조건을 추출하였고 여기에 스케줄링 문제를 해결하기 위한 방법으로 제약만족문제(CSP) 해결기법인 도메인 여과기법을 적용하였다. 도메인 여과기법은 제약조건에 의해 변수가 갖는 도메인의 불필요한 부분을 여과하는 것으로 제약조건과 관련되어 있는 변수의 도매인 크기가 축소되는 것이다. 또한, 스케줄링을 하는데에 있어서 비용적인 측면에서의 스케줄링방법과 고객만족도에서의 스케줄링 방법을 비교하여 가장 이상적인 해를 찾는데 트래이드오프(Trade-off)를 이용하여 최적의 해를 구했으며 실험을 통해 인력에게 더욱 효율적으로 작업들을 배정 할 수 있었고 또한, 정해진 시간에 많은 작업을 처리 할 수 있었으며 작업을 처리하는데 있어 소요되는 비용을 감소하는 결과를 얻을 수 있었다.

The ROK's military is attempting to change to advanced information science force through 'the Defense Reform 2020', which essentially creates the requirements of new military force. Therefore, the importance of defense industry and defense budget have been emphasized in order to successfully promote military build-up. However, the ROK defence industry has been going serious difficulties in the present day, and what is worse, unreliable rationality stability of Defense Capability Improvement Cost put the industry in the harder situation. In this circumstances, the improvement measures of the rationality stability of Defense Capability Improvement Cost should be immediately studied to satisfy the requirements of ROK military force in a suitable time and the development of ROK defense industry. The purpose of this study was to propose reinforcement measures to improve the arrangement system of yearly allocation for Mid-term Defense Plan of defense capability improvement programs and connect Mid-term Defense Plan to National Fiscal Management Plan to raise the rationality stability of ROK Defense Capability Improvement Cost.

This research proposes a methodology to evaluate the rationality of passengers' route choice who make trips within Seoul metropolitan subway based on smart card data. The rationality of user route choice is divided into the degree of determinacy and similarity concepts as basic principle. Determinacy is the degree to which the route selected by the passenger is identical to the system optimal path. Similarity indicates the degree to which the route is similar to the system optimal path. The K-path search method is used for path enumeration, which allows for measurement of determinacy. To assess determinacy within similarity, transfer tag data of private operators is used. Consequently, the concept of similarity applied to the model is such that the passenger's path choice is identical to the path taken using the tag reader. Results show that the determinacy of appearance of the shortest path (K=1) is 90.4%, while the similarity of appearance as K=(2-10) is 7.9%, summing to 98.3%. This indicates that trips on the metropolitan subway network are being rationally explained. 1.7% of irrational trips are attributed to the unexplainable error term that occurs due to the diversity of passengers.

This paper deals with two methods regarding fact and value. One is the method of H. Putnam, which is to break the boundary between fact and value and to make a world where the two have an inherent connection. The other is the method of J. Habermas, which regards fact and value as the product of an intersubjective agreement based on argumentation. Putnam, through his position of internal realism, moves from realism to pragmatism, especially by combining the rationalist tradition of Kant and Dewey's pragmatic views. Habermas also stands in the tradition of rationalism and universalism in Kant, at the same time emphasizing the practicability of truth in Hegel's tradition of historical reason. The significance of the strategy of Putnam and Habermas is that they have attempted to revive the realm of value against the strict dichotomy of facts and values and the subsequent devaluation of rationality in the realm of value. The starting point of this attempt is that the practical foundation of rationality is laid on life and practice. This could provide the room for escaping from rationality, which prioritizes only truths that reveal facts, that is, instrument-reduced rationality, the room for the revival of practical rationality through reflection on what is the purpose of life, and, in turn, the room for resisting to pass the realm of values and norms to the logic of habitual routines or customs. However, despite such common goal, there are clear limitations to Putnam's approach due to the differences in the strategies taken on facts and values. Putnam's method can demolish the whole universal framework that is the foundation where pragmatic pluralism will be fostered, eliminating the difference between the specificity of values and the universality of norms and shaking up the status of universal ethics. Therefore, Habermas' ethical theory is proposed as an alternative to establish a basis for universal ethics by relying on communication rationality and to secure the coercion of norms and blossom cultural pluralism as a diverse lifestyle based on this coercion.
