Global logistics and outsourcing have become an irreversible industrial development trend in today's technology industry. Previous studies differ on supplier selection, supplier development, and supply-chain performance assessment evaluation methods. Research suggests that outsourcing is not only a program of options, but also results in different operating performances based on varying company supply-chain strategies. To build a competitive supply chain, companies must conduct a comprehensive assessment and develop a clear and explicit supply-chain development strategy. This research derives a composite method for assessing supply-chain strategy. A decision-making trial and evaluation laboratory method first clarify six major areas of supply-chain strategy assessment, and then draw a network impact-relationship map based on the direction of influence and extent of the impact in each area. An analytic network process then captures the interdependence between the evaluating factors, and identifies the relative weight of these criteria for each major factor in the supply-chain development strategy. Finally, the study develops an effective supply-chain strategy decision-making assessment model to help companies select an optimal strategy. Examining the world's top 4 TFT-LCD factories validates the results of this study.

The purpose of this study was to collect key success factors (KSFs) that determine information security management in cloud computing. Through contemporary literature reviews, we emphasized four major aspects: the external dimension, the internal dimension, the technology dimension, and the execution dimension. We used these dimensions to develop a questionnaire for collecting the responses from experts, and then used the fuzzy analytic hierarchy process (Fuzzy AHP) to categorize and analyze these responses. The investigations concluded the six major KFSs: authentication, disclosure prevention, encryption, service model, interface, and customer. Different from previous perceptions, information security management in cloud computing emphasizes factors that are more market-oriented. In addition, we explored several important KSFs, such as service model, interface, and customer criteria. These KSFs differed from the factors commonly regarded in the internet age.

The first single-loop current sensorless control (SLCSC) for single-phase boost-type switching-mode-rectifier (SMR) had been proposed in the prior paper. SLCSC with sinusoidal input voltage possesses good performance, but its performance with distorted input voltage should be improved. In this paper, a modified SLCSC is proposed and implemented in a field-programmable gate array (FPGA)-based system to obtain better performance than SLCSC. Instead of the phase-shift signal in SLCSC, the inductor voltage amplitude signal becomes the output of proportional-plus-integral (PI)-type voltage controller in the modified SLCSC. The provided simulation and experiment results demonstrate the modified SLCSC.
