Many research papers on transportation studies have focused on the Vehicle Routing Problem (VRP) and Vehicle Scheduling Problem (VSP). However in the real world, it is known that it takes long time to build vehicle scheduling in the process of transporting the amount of orders from the logistics center to the vendors due to the realistic constraints. This paper presents a framework design for each process enabling delivery planning automatically using heuristic algorithm. In addition, an interactive automatic delivery planning system is implemented utilizing the proposed algorithm.

Globalization of Economic activities have increased Company's interests about International Logistics Management. Expansion of International trade depends on International Logistics which can overcome distance and time. In In-cheon, There are many small scale and minor Freight Forwarders take advantage of being linked with a port, an airport but their inefficient paper works cause raising of Logistics costs and losing of competitive power. In this study, we design a web based ocean forwarder information system for freight forwarder to solve these problems. So, this system will provide decreasing operation time, human resources, and accessing easily because of web based system, and finally decrease logistics cost and improve national competitive power.

Co Evolutionary Structural Design(CESD) Framework is presented, which can deal with the load design and structural topology design simultaneously. The load design here is the exploration algorithm that finds the critical load patterns of the given structure. In general, the load pattern is a crucial factor in determining the structural topology and being selected from the experts어 intuition and experience. However, if any of the critical load patterns would be excluded during the process of problem formation, the solution structure might show inadequate performance under the load pattern. Otherwise if some reinforcement method such as safety factor method would be utilized, the solution structure could result in inefficient conservativeness. On the other hand, the CESD has the ability of automatically finding the most critical load patterns and can help the structural solution evolve into the robust design. The CESD is made up of a load design discipline and a structural topology design discipline both of which have the fully coupled relation each other. This coupling is resolved iteratively until the resultant solution can resist against all the possible load patterns and both disciplines evolve into the solution structure with the mutual help or competition. To verify the usefulness of this approach, the 10 bar truss and the jacket type offshore structure are presented. SORA(Sequential Optimization & Reliability Assessment) is adopted in CESD as a probabilistic optimization methodology, and its usefulness in decreasing the computational cost is verified also.

이상의 연구 성과를 정리하면 다음과 같다. 1) 장비의 설치 및 취급이 간편하고, 해양생물의 순간적인 상세한 행동을 비교적 쉽게 추적할 수 있는 새로운 바이오텔레메터리 방식을 개발하였다. 바이오텔레메터리 방식에서 핑거에 수온, 압력센서 등의 추가는 핑거를 부착하는 어류에 많은 부담이 되기 때문에 수신계를 고도화함으로써 행동추적을 행하는 방법으로 하였다. 이 방식은 거리-방위의 측정원리를 이용한다. 즉, 거리를 계측하기 위해서 핑거동기 방식을 이용하고, 방위를 계측하기 위해서 SSBL방식을 채용하여, 거리와 방위를 조합(SPB 방식)함으로서 대상어의 수파기에 대한 상대위치를 구한다. 최대감도방식은 어류의 상세한 위치를 특정하기가 어렵고, 음원측위방식은 항주하는 선박에 의해 넓은 범위의 추적이 곤란하며, 또한 장비의 설치나 취급이 간편하지 못하였으나, SPB 방식에 의해 이들 결점을 대폭 해결할 수 있었다. 2) 새로운 방식으로서 개발한 SPB 방식의 시스템을 설계하였으며, 시작시스템을 제작하였다. 설계에서는 SSBL 방식과 핑거동기 방식의 기술을 조합함과 동시에 각각의 기술을 고도화하여 SPB 방식에 의해 고정도 또는 광범위 검지가 가능하도록 하였다. 따라서, 수파기는 1개로 하여 어레이의 구성의 변환에 의해 검지범위 또는 방위측정정도를 선택할 수 있도록 2개의 빔 모드로 구성 하였다. 주파수는 70kHz로 하였으며, 음원음압 136dB에서 최대검지거리 258m와 457m, 검지빔폭 76˚와 29˚ 를 실현할 수 있었다. 전체적인 시작시스템은 핑거, 2개의 빔모드로 구성된 수파기, 2개의 빔 모드용에 각 2개의 채널로 구성된 수신기, 디지털오실로스코프, 퍼스널컴퓨터로 구축하였다. 핑거동기 방식의 이용에 따른 측정거리오차는 수온변화에 의한 송신주기의 변화를 측정하여 최소화하도록 하였다. 핑거 부근의 수온을 알 수 있다면 핑거 송신주기의 수온특성을 보정하여 74%정도 측정거리오차를 줄일 수 있지만, 장기간에 걸쳐 추적을 하기 위해서는 다른 보정방법의 개발이 필요함을 알 수 있었다.
