This paper studies the simultaneous reshuffle and yard crane scheduling problem in the yard of container terminals, which is one of the key logistics problems affecting the operation efficiency in container terminals. Although the reshuffle scheduling problem has received many research attention due to its importance, the problem without considering yard crane is not very practical, which is be...

This study compared the environmental impacts of composting yard wastes in windrows with using them in place of soil as alternative daily cover (ADC) in landfills. The Life Cycle Assessment was made using the SimaPro LCA software and showed that the ADC scenario is more beneficial for the environment than windrow composting. ADC use is also a less costly means of disposal of yard wastes. This f...

Total or partial condemnation of carcasses in the slaughter houses has always been a major concern for the poultry industry as it represents huge economical losses for companies. In the United States of America, losses due to cellulitis, an inflammation of the subcutaneous tissue of broilers (usually contaminated with Escherichia coli), exceed 35 million USD per year. Combined with other losses...

The aim of this paper is to explore the possibility of using rhythm metrics on the traditional units of speech rhythm (the syllable and the foot), instead of applying them to consonantal and vocalic intervals. Despite [14] had already proven that the standard deviation of syllables and feet did not provide a satisfactory representation of the traditional rhythm classes, some recent studies obta...

For phase transitions in disordered systems, an exact theorem provides a bound on the finite size correlation length exponent: nFS $ 2yd. It is believed that the intrinsic n satisfies the same bound. We argue that the standard averaging introduces a noise and a new diverging length scale. For n # 2yd self-averaging breaks down, disconnecting n from nFS, and the bound applies only for the latter...

This paper is concerned with yard management in transshipment hubs, where a consignment strategy is often used to reduce reshuffling and vessel turnaround time. This strategy groups unloaded containers according to their destination vessels. In this strategy, yard template determines the assignment of the spaces (subblocks) in the yard to the vessels. This paper studies how to make a robust yar...

Since the premium prices of yard trucks and significantly daily volatility of containers serving demand, it is an uneconomic method to keep a full team of fleet to cover the entire service. Some of the transportation services are outsourced to other external companies. The strategy of outsourcing yard trucks is a decision making problem that container terminals are currently facing. Yard truck ...

This paper proposes an ant colony optimization algorithm to assist railroad yard operational planning staff in their daily tasks. The proposed algorithm tries to minimize a multi-objective function that considers both fixed and variable transportation costs involved in moving railroad cars within the railroad yard area. This is accomplished by searching the best switch engine schedule for a giv...

The efficiency of container handling has got great improvement with the usage of the 40ft quay crane and the twin 40 ft yard crane. Reasonable bay planning strategies is necessary to reach the high handing efficiency by the twin 40 ft yard crane. This paper studies both bay planning and row planning for yard bay allocation. The models of bay planning and row planning are created, and the discre...
