Analysis of container dwell time on marine terminal throughput and rehandling productivity

Rehandling Strategies for Container Retrieval

In this work, we consider the problem of optimizing the retrieval of containers from a bay in a fixed sequence. When there are other containers on top of the container to be retrieved, there may be alternative locations for those containers to be relocated. So it is essential to develop algorithms that find “good” locations in order to minimize the total time of the retrieval. In the literature...

Security Inspection Protocols: Impact on Container Terminal Throughput Using Simulation

This paper presents a simulation model to determine the impact of various container inspection protocols on the operation of a seaport container terminal. The inspection protocols are A) no inspection, B) container sampling with unloading and inspection coupled and C) inspection after unloading or decoupling inspection from unloading. Any sampling plan using Protocol B had an impact on entity t...

the effects of time planning and task complexity on accuracy of narrative task performance

هدف اصلی این تحقیق بررسی تاثیر برنامه ریزی زمانی، هم چنین افزایش میزان پیچیدگی تکالیف در نظر گرفته شده بصورت همزمان، بر دقت و صحت و پیچیدگی عملکرد نوشتاری زبان آموزان می باشد. بدین منظور، 50 نفر از دانش آموزان دختر در رده ی سنی 16 الی 18 سال به عنوان شرکت کنندگان در این زمینه ی تحقیق در نظر گرفته شدند و به دو گروه آزمایشی و کنترل بصورت اتفاقی تقسیم شدند. اعضای گروه آزمایشی هر دو تکلیف ساده و پی...

Crane Double Cycling in Container Ports: Effect on Ship Dwell Time

Quay Crane Allocation of Container Terminal Based on Cluster Analysis

Quay crane allocation is one of the most important scheduling plans in the container terminal. A large of production data is stored in the database of the terminal. This paper utilizes the method of data mining to analyze the problem of quay crane allocation by using these data. From the mining, valuable information has been gotten from the database. The paper chooses the fuzzy cmeans cluster a...
