In manufacturing systems, generally employee timetabling and job shop scheduling is considered to be too hard and complex. To achieve an integrated manufacturing environment, the integration of employee timetabling and job shop scheduling is essential. It is a process of assigning employees into work slots in a pattern according to the hierarchy level of the employee, job allotment, individual ...

The paper presents using Differential Evolution (DE) and Shuffled Frog Leaping Algorithm (SFLA) to optimally tune parameters of a fuzzy logic controller stabilizing a rotary inverted pendulum system at its upright equilibrium position. Both the DE and SFLA are meta-heuristic search methods. DE belongs to the class of evolutionary algorithms while SFLA is inspired from the memetic evolution of a...

Several benefits can be gained from implementation of Distributed Energy Resources (DERs) in distributed systems. This paper proposes the application of Shuffled Frog Leaping Algorithm to optimally determination the location and size of multiple DERs considering a multi-objective benchmark. Several objectives including loss minimization, reduction in power purchased from the network and upgrade...

Service-oriented architecture provides the ability to combine several web services in order fulfil a user-specific requirement. In dynamic environments, appearance of unforeseen events can destabilize composite service (CWS) and affect its quality. To deal with these issues, must be dynamically reconfigured. Dynamic reconfiguration may enhanced by avoiding invocation degraded predicting QoS for...

In order to achieve the sensing, communication and processing tasks of Wireless Sensor Networks, an energy-efficient routing protocol is required to manage the dissipated energy of the network and to minimalize the traffic and the overhead during the data transmission stages. Clustering is the most common technique to balance energy consumption amongst all sensor nodes throughout the network. I...

Activity-based costing (ABC) system more precisely allocates the overhead costs to cost objects (products, services or customers) than traditional costing systems. In ABC, resources are consumed by the activities, and multiple cost drivers are used to allocate the costs of activities to the products. The selection of activity and cost drivers is then highly significant. Using too few cost drive...

In energy-limited WSNs, coverage and connectivity are two of the most fundamental QoS issues, which have a great impact on the performance of WSNs for minimizing the node energy consumption and maximizing the network coverage lifetime. Due to the node distribution, the energy consumption among nodes is more imbalanced in cluster-based WSNs. Based on this problem, this paper proposes Sink Mobili...
