Calculation of GMPH oriented optimum storage capacity incontainer ports

The increase in the world trade volume in terms of value and quantity and the increasing importance of the concept of economic globalization have increased the importance of the effective use of logistics modes. Since the ports are the transit point of the logistics modes, their performance, capacity and service quality are very important for the economies of the country and the region. For this reason, capacity and performance studies in ports have always attracted the attention of academics In the study, definitions of capacity types and performance measurement types for container terminals were made and calculation methods were formulated. The definition of optimum storage capacity as a type of capacity was made, and the relationship between performance targets and service quality and storage capacity has been mentioned. The motivation of the study is to calculate the optimum storage capacity in which the ports can use the yard equipment and operations most effectively at the focal point of the hourly performance (GMPH) which they aim to produce in vessel operations. Regression and Correlation analyzes were made using the data of a certain time period that belongs to a port operator operating in Turkey and the optimum storage capacity was calculated for the targeted hourly vessel operation performance.
