In this paper we propose a simulation framework that allows for the analysis of power and performance trade-offs for data centres that save energy via power management. The models are cooperating discrete-event and agent-based models, which enable a variety of data centre configurations, including various infrastructural choices, workload models, (heterogeneous) servers and power management str...

This study investigates the impacts of resource sharing on the supply chain efficiency. Due to the increased emphasis on efficiency, modern supply chain processes are no longer labour-intensive. Supply chain management should particularly consider resource sharing. The queuing and AnyLogic approaches are developed in this paper to model and simulate complex supply chain operations. First, based...

One of the main issues on task planning of the enterprises with several production sites is how they can reassign tasks when a part of the supply chain is stopped. In this case, a good re-schedule, involving parts from supply chains from other sites, could imply to reduce overall costs. In this paper, we propose a cooperative system to re-schedule a network chain. The algorithm proposed is desc...

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...
