The designed HDD template is a high flexibility and good performance at an internal supply chain level and self-development and improves the system performance significantly. It is developed the intelligent based dynamic machine knowledge, which can capture dynamic based activities with fuzzy system. The study shows how modeling and simulation tools can be used and integrated to implement highly automated systems for industrial processes and deal with flexible products. In such context we designed and developed a prototype for the final assembly of hard disk drive with dynamic and static behavior.

At the same time, web-enabled platforms are required to perform remote monitoring with efficiently and effectively. Recent progresses on e-manufacturing applications address the needs for better integration between factory floor and enterprise systems. This paper presents a web-enabled platform which focuses on web-enabled intelligence to enable products and systems to achieve near-zerodowntime performance through device-to-business (D2B) platform. The proposed web-enabled platform can effectively minimize the massive information bottleneck that exists between plant floor and information systems. Case studies are presented to determine how effectively web-enabled industrial system can be used in factory floor as well as business decision-making. Manufacturers and users will benefit from the increased equipment and process performance with the effective implementation of the developed web-enable platform.

The industrial low voltage distribution network may be utilized as a communication channel to data transfer required by the on-line condition monitoring of electric motors. The advantage of using power-line data transfer is that it does not require the installing of new cables. In this paper, a pilot distribution network is formed and analyzed. The transfer function of the power line channel is calculated and the signal attenuation in communication channels in the pilot environment is analyzed by varying the parameter that affects the signal attenuation.
