This paper presents a generic simulation model to determine the equipment mix (quay, yard and intra-terminal transfer) for Container Terminal Logistics Operations System (CTLOS). The CTLOS, typical type of discrete event dynamic system (DEDS), consists three sub-models: ship queue, loading-unloading operations yard-gate operations. is empirically applied phase 1 Yangshan Deep Water Port in Shan...

The mechanical properties of demineralized bovine cortical femur bone were investigated by cyclic loading-unloading compression in three anatomical directions (longitudinal, radial, transverse) within the physiological strain range. The loading responses in the radial and transverse directions were nearly linear up to 2% strain, while the response in longitudinal direction was strongly non-line...

One of the most critical activities in a refinery is the scheduling of loading and unloading of crude oil. Better analysis of this activity gives rise to better use of a system's resources, as well as control of the entire supply chain. It is important that the crude oil is loaded and unloaded contiguously, primarily for security reasons (e.g. possibility of system failures) but also to reduce ...

This paper considers the parcel hub scheduling problem (PHSP) with unequal batch size inbound trailers, which is a combinatorial optimization problem commonly found in a parcel consolidation terminal in the parcel delivery industry (PDI). The problem consists of processing a large number of inbound trailers at a much smaller number of unload docks. The parcels in the inbound trailers must be un...

knowledge of the aerodynamic properties of agricultural materials is needed in equip-ment design for operations such as pneumatic conveying in loading/unloading operations of corn silage into/from silos. while considerable information is available on seed grains, little is known about the aerodynamic behavior of corn (zea mays l.) silage. in this re-search, the weighed mean terminal velocity of...

Technical operation of lifting and transport equipment is one the key problems ports terminals. The functions technical include maintenance repair equipment. imperfection system leads to downtime equipment, which affects cost loading unloading operations. main requirements for are ensure quality speed operations with minimal operating costs. One indicators assessing coefficient readiness, shows...

We present a framework for modeling and heuristic solving of large-scale real-world vehicle routing and scheduling problems (VRPSs). Real-world problems have in common that their size is usually large or very large (including thousands of requests) and that they include a number of side constraints that are not present in the abstract standard models that are usually considered in the Operation...

Early tendon healing can be stimulated by mechanical loading and inhibited by cyclooxygenase (COX) inhibitors (nonsteroidal anti-inflammatory drugs). Therefore, we investigated if impairment of tendon healing by a COX-2 inhibitor (parecoxib) is related to loading. Because loading might infer microdamage, which also stimulates healing, we also investigated if this effect is inhibited by parecoxi...

As a strain rate-dependent material, bone has a different mechanical response to various loads. Our aim was to evaluate the effect of water and different loading/unloading rates on the nanomechanical properties of canine femur cortical bone. Six cross-sections were cut from the diaphysis of six dog femurs and were nanoindented in their cortical area. Both dry and wet conditions were taken into ...

The tremendous increase of containerized trade over the last several years, the resulting congestion in container terminals worldwide, the remarkable increase in containership size and capacity, the increased operating cost of container vessels and the adoption by liner shipping companies of yield management techniques strain the relationships between ocean carriers and container terminal opera...
