  • We examine berth allocation problems in tidal bulk ports with an objective of minimizing the demurrage and dispatch associated berthing cost. In the proposed optimization model inventory (or stock) level constraints are considered so as to satisfy the service level requirements in bulk terminals. It is shown that the mathematical programming formulation of this research provides improved schedule resolution and solution accuracy. We also show that the conventional big-M method of standard resource allocation models can be exempted in tidal bulk ports, and thus the computational efficiency can be significantly improved.

  • 관성 에너지 저장 장치인 HESS (Hoop Energy Storage System)의 안정적인 운용을 위해 가장 중요한 자기 반발력하에서의 안정화 조건을 dipole approximation을 이용하여 계산하였다. 또한 고주파 입출력을 고려하여 공심코일을 이용한 자기유도 실험을 통하여 HESS에 있어서 가능한 출력을 예측하여 보았다.
