چکیده

هدف از این مطالعه بررسی تأثیر سیستم کنترل و هدایت خودکار کشتی جهت پهلودهی و جداسازی از اسکله و به طور خاص در بندر امام خمینی (ره) می‌باشد. این پژوهش از نظر ماهیت کاربردی و از نظر روش تحقیق، توصیفی و علی است. براساس مدل طراحی شده بر پایه مبانی نظری پژوهش، پرسشنامه‌ای به منظور جمع‌آوری داده‌ها طراحی گردید که روایی، ابعاد و گویه‌های پرسشنامه توسط اساتید راهنما مورد تأیید و همچنین پایایی، با استفاده از آزمون کرونباخ مورد تأیید قرار گرفتند. در این مطالعه 217 نفر از کارکنان سازمان بنادر و دریانوردی بندر امام خمینی (ره) مورد بررسی قرار گرفتند. به منظور تجزیه و تحلیل داده‌ها از دو نرم افزار SPSS نسخه 22 و LISREL از نسخه 8.51 بهره گرفته شده است. نتایج بدست آمده از آزمون‌های معادلات ساختاری نشان داد که تمام فرضیه‌ها مورد تأیید است. بررسی تأثیر بکارگیری سیستم هدایت خودکار کشتی بر کاهش خطای عوامل فنی و فیزیکی، کاهش خطای ناوبری در شرایط محیطی نامناسب و عوامل فیزیکی و فنی که منجرب به خطا می‌شود، تاثیر مثبت و معناداری دارد. همچنین باتوجه به مقدار ضریب مسیر فرضیه‌های اصلی پژوهش، کاهش خطای ناوبری در شرایط محیطی نامناسب با مقدار ضریب مسیر 1.96 بیشترین تأثیر را نسبت به ایجاد سیستم هدایت خودکار در کشتی دارد.

چکیده [English]

The purpose of this study was to investigate the effect of the automatic control and guidance system of the ship for flooding and separation from the berth and in particular in Imam Khomeini port. This research is descriptive and causal in terms of applied and research method. Based on the designed model based on theoretical foundations of the research, a questionnaire was designed for data collection. Validity, dimensions and items of the questionnaire were confirmed by supervised professors as well as reliability, using Cronbach's test. In this study, 217 employees of Port and Shipping Organization of Bandar Imam Khomeini (RA) were surveyed. Data were analyzed using SPSS version 22 and LISREL software version 8.51. The results obtained from structural equation tests showed that all hypotheses were confirmed. Effect of using the ship's automatic guidance system on the reduction of technical and physical errors, reducing the navigational error in inappropriate environmental conditions and the physical and technical factors that are due to error has a positive and significant impact. Also, considering the amount of path coefficient of the main hypotheses of the research, reducing the navigation error in inappropriate environmental conditions with the path coefficient of 1.96 has the greatest effect on the creation of an automatic guidance system on the ship.
