This study investigates the effects of canopy fabric material and vent diameter on the deployment performance of sea anchors for fishing operations through field experiments. Three canopy configurations were tested: polyamide (PA), polyester (PES), and a PA – PES alternating combination. Vent diameters of 80 cm and 40 cm were applied to each fabric as controlled structural factors. Deployment performance was evaluated from entrance diameter computed using four evenly spaced water level loggers, and maximum towing tension was recorded with a load cell. Key findings were discovered as follows: PES and the PA – PES mix achieved deployment diameter/ratio and maximum tension comparable to the current PA standard, indicating practical substitutability. PES also exhibited superior stability, showing reduced variability even with the smaller vent (a change in standard deviation ΔSD-1.75 cm). The mixed canopy maintained performance similar to PA. As expected, vent diameter systematically affected geometry and load (80 cm: 187 – 198 kgf vs. 40 cm: 249 – 268 kgf), underscoring the need to pair material selection with appropriate vent sizing. In conclusion, PES and mixed fabrics are viable alternatives to PA, and co-optimization of fabric choice and vent diameter can enhance sea-anchor performance, durability, and operational reliability for fishing operations.

본 연구는 컨테이너 터미널의 종합적인 성과 향상 요인을 분석하기 위한 균형성과표(BSC)를 설계한 후 분석계층프로세스 모형(AHP)과 분석네트워크프로세스 모형(ANP)을 활용하여 품질기능전개도(QFD)와 결합 모형을 사용하였다. 이는 재무적 성과, 고객 만족 및 컨테이너 터미널의 비즈니스 프로세스의 질적 향상을 가져 올 수 있는 컨테이너 터미널의 종합적이고 다차원적인 성과 요인 제시 및 중요도 분석에 목적을 두고 있다. 본 연구에서 제안한 수정된 품질기능전개도는 상관종속성과 관계행렬을 표현하므로 인해, 기존의 품질기능전개도와 비해 더욱 현실적이며 정확성과 정교성이 부가된 품질기능전개도를 구축했다.
