Integrated solutions for product delivery planning and scheduling in distribution centres are proposed and built on a cluster analysis and simulation optimisation methodology. A cluster analysis of product demand data of stores is used to identify typical dynamic demand patterns and product delivery tactical plans. Further, simulation optimisation techniques are applied to find optimal paramete...

According to the operation of automotive supply chain and the features of various simulation methods, we create and simulate a automotive supply chain network model with the core enterprise of two vehicle manufacturers, consisting of several parts suppliers, vehicle distributors and logistics service providers. On this basis of a conceptual model including the establishment of enterprise layer,...

Both free and low-priced mobile wireless networks are expanding and its users are more numerous every day. This success is particularly due to the mobility offered to users. These networks have promoted and widespread the success and availability of mobile devices and their access technologies such as Wi-Fi, WiMAX and Bluetooth. Nevertheless, despite of their wide success, the problem is that t...

The novelty of this paper is a hybrid approach for modeling and implementing a real-time control strategy of a dc Servomotor angular speed by using a sliding mode control module. The sliding mode controller is embedded in an open-loop control system structure with a dc Buck converter to stabilize and regulate the converter output voltage, despite the load current changes and unregulated power s...

This study provides data on the optimal staff, materials, space, and time resources required to operate a regional hub reception center, a “short-term facility with the goal to process and transport displaced survivors (evacuees) to temporary or permanent shelters following a catastrophic incident” (Regional Catastrophic Planning Team, 2012). The facility will process approximately 20,000 evacu...
