Abstract:Quay crane drivers are the main parts of stevedoring workforce in the container terminal. For various berthing time periods of ships, uncertain numbers of loaded and unloaded containers, and work burden limitations of drivers, their task assignment is different than the workforce's in the general business companies. The studied company exploits a cyclic assignment principle to dispatch quay crane drivers by manual operations. No matter the time expenditure of execution or the flexibility of planning, it has always a little bit of rigidity. This paper designs a computer program according to this principle for accelerating the implementing process of driver scheduling. Meanwhile, we use mathematical programming technique to formulate a scheduling model for driver manpower. The test results of the studied company case show that this model is suitable for the practical arrangement of driver scheduling in this company and reveal that the current manpower can reduce a little more. In the basis of the formulated model, it can be considered more flexible planning of driver workforce in the future.
