بهينهسازي حمل و نقل مواد غله بر اساس يك مدل شبيه سازي در بندر شهيدرجايي

Optimization of Cereal Transportation System at Shahid Rajaee Container Port based on a simulation optimization model

با در نظرگيري افزايش روز افزون تقاضا براي فعاليتهاي عملياتي در بنادر، مديران بنادر با چالش استفاده بهينه از تجهيزات و تسهيلات بندري رو به رو ميباشند. يكي از اين چالشها جلوگيري از ماندگاري زياد كشتيها در بنادر م باشد. بدين منظور در اين مطالعه به بررسي ايجاد انبار موقت در بندر خدماتي شهيد رجايي براي بارگيري غلات به كشتي با استفاده از يك مدل شبيه سازي بر پايه تيوري صف خواهيم پرداخت. در اين راستا، برخي از معيارهاي مهم نظير زمان سيستم كشتي ها، تعداد كشتيها ي بارگيري شده و نرم بارگيري در نظر گرفته شده است. نتايج نشان ميدهد كه بهينه سازي حمل و نقل غلاتها بين انبار موقت و اسكله ظرفيت حمل و نقل و بارگيري را به ميزان 1555 درصد افزايش خواهد داد

Considering the increasing demand for operational activities in ports, ports managers are facing the challenge of optimal usage of port facilities and equipment. (In the last two decades, maritime transportation systems have been experienced an increasing development. Now the rate of development in this section has been reached 8 percent per year. Nowadays, the port managers are faced with the challenge of optimal use of equipment and facilities). One of these challenges is to reduce the waiting times of ships at the ports.so that in this study, placing the buffer area for loading and unloading cereals has been investigated using a simulation optimization model based on queuing theory at SHAHID RAJAEE port. Three important criteria of the port performance have been considered including the ship turn-around time, number of loaded ships and loading norm. The results indicate that optimization of cereal transportation between the buffer area and the port can increase the capacity of transportation and loading- unloading capacity up to (The results show that the proposed model can increase the capacity of loading and unloading of the system up to %15.5 between the port and buffer area
