The up-to-date small and medium-sized enterprises (SMEs) in Korea have tried to respond flexibly and rapidly to dynamic business environment and to establish efficient production management system based on information technologies. However, most of SMEs have faced with low applicability of the production management system resulting from high costs of introduction and maintenance. In this paper, a production planning and control system, that is S-PMS (production management system for SMEs), is proposed to solve the problem of low applicability and limited human resources. S-PMS enables production managers to efficiently collect and manage master data with the actual target production systems and explores the bottleneck process by means of simulation techniques to improve productivity. Furthermore, it implements rescheduling mechanism in terms of a variety of process routes. In essence, intuitive dispatching rules and integrated data management of S-PMS improve field applicability of production management system. Consequently, S-PMS is expected to be used as an efficient production management system of SMEs in Korea.

The CSR rule was defined by IACS as the unified rule for a commercial ship like a bulk carrier and a tanker. It have been required more strict conditions for various parts like loading conditions, the local and girder strength, fatigue strength, FEM for the ship rule. It was changed in many parts of the ship rules. In this paper, the mid-parts of 17.5K DWT bulk carrier were optimized by the CSR rule. On the other hand, the modified artificial life algorithms with multi-object functions were developed for optimizing the scantling. It is possible to find multi-global optimum solutions in the multi-object functions. And it is faster and efficient than the artificial life algorithm. First, to be optimizing the scantling and the weight by CSR rule, that is calculated by the CSR rule. The next, the result is re-calculated by the modified artificial life algorithm with multi-object functions. The optimized results which are satisfied with the CSR rule like the minimum size and the thickness of stiffener and the minimum cost have been searched by the optimizing algorithm. And the results have been compared with the non-optimizing results.

고대 그리스의 완벽한 비례로 부터 출발한 황금비율은 아름다움을 추구하려는 노력에도 불구하고 실제의 적용에 있어서 그 한계를 드러내 왔다. 그러한 증거는 고대 그리스의 파르테논 신전으로, 이 건축물은 우리가 지금까지 인식한 것처럼 완벽한 황금비율에 의해 건축되지 않았다. 또한 르네상스 시대의 레오나르도 다빈치와 미켈란젤로의 설계도 역시 명확한 근거를 제시하지 못하고 있다. 그러나 현대의 건축가인 르 코르뷔지에는 황금분할에 의해 완성되는 황금비율을 통한 스스로의 모듈을 개발하여 이를 자신의 건축에 적용시켜 왔다. 따라서 본 연구에서는 현대의 건축가인 르 코르뷔지에의 유니테 다비따시옹과 피르미니 베르에 실제로 드러난 황금분할 분석을 통한 모듈을 이해하고, 황금비율이 실제로 적용이 가능하다는 것에 대한 연구자 만의 새로운 모듈의 형식을 제시하고자 한다. 이러한 연구는 앞으로 건축설계에 있어 새로운 가능성과 함께 합리적인 디자인을 위한 하나의 방법이 될 것으로 전망된다.
