Application of Fuzzy Theory to the Evaluation Model of Product Assembly Design and Usability Operation Complexity

In order to make people’s lives more convenient and enhance living standards, the composition of a product usually includes more than one component. However, a product is created by the joint endeavor of people from various territories and therefore one of the important considerations is making a product merge into consumers’ daily lives rather than simply fulfilling its functions. There might be conflicts with people’s existing life patterns or existing values, which should be taken into consideration during the manufacturing process. This study is an investigation of the process of assembly by considering the assembly operations and the assembly operating time. By determining the relationship between components, the assembly concept of most components was analyzed. A fuzzy comprehensive evaluation was carried out during the evaluation of the degree of complexity of user operations. Depending on the ranking of membership, the most appropriate assembly was determined and this serves as a reference for designers to select the optimal product assembly. By recording the consumer usage models, the optimal assembly and usage model of product design were also proposed. The goal of this study is to find the balance between assembly evaluation and user usage model by the process in order to allow designers to determine the new assembly concepts that meet consumer usage models. A case study of four bedside stereos was carried out by implementing the proposed approach in order to determine the evaluation principle of assembly. The purpose of this is to enhance the balance between assembly design and user operation complexity for making efficient decisions. A product design can comply with the spirit of concurrent engineering and the quality of a product design can be enhanced.

KOMPARASI MODEL PENGARUH KUALITAS LAYANAN TERHADAP KEPUASAN DAN LOYALITAS DEBITUR KUPEDES BRI BANGSALSARI BERDASARKAN SUKU

This study compares the usage models of Kupedes credit of Bank Rakyat Indonesia (BRI) Bangsalsari Jember, between the Javanese and Madurese debtors by analyzing the effect of service quality on satisfaction and loyalty of the debtors. The population is all Kupedes debtors of Javanese and Madurese in BRI Bangsalsari Jember. The sample consists of 120 Javanese debtors and 120 Madurese debtors taken by cluster sampling, purposive sampling, and quota sampling methods. The compared models were analyzed by Structural Equation Modeling (SEM) and comparative test of the two models. The results show that for the Javanese debtors, service quality has no effect on satisfaction, service quality significantly affects loyalty, and satisfaction significantly affects loyalty. For the Madurese debtors, service quality has no effect on satisfaction, service quality has no effect on loyalty, and satisfaction significantly affects loyalty. Keywords: Service Quality, Debtor Satisfaction, Debtor Loyalty

A Study of Bluetooth Wireless Technology Using Recent Attacks

Bluetooth is a wireless technology that is used for the exchange of information over a network for short separations. It is a low controlled, short range application. It utilizes Bluetooth to convey to other Bluetooth-empowered gadgets because it is a communication protocol. Bluetooth resembles some other correspondence convention that you utilize each day, for example, HTTP, FTP, SMTP, or IMAP. Bluetooth is designed to connect with monitor and mouse without any connection with CPU. Different kinds of Bluetooth gadgets are headsets, Bluetooth prepared printer, in-auto Bluetooth framework, Bluetooth gps framework, Bluetooth console, Bluetooth prepared webcam and so on. Bluetooth advancement tends to an open entryway for the business to pass on remote arrangements that are unavoidable over an expansive scope of gadgets. The constraints and properties of Bluetooth scatter presents remarkable troubles in framing a system in which all devices communicate with each other directly. In this paper, detailed description of Bluetooth along with its working is given. Description also includes connection protocols of the Bluetooth, usage models, advantages and dis-advantages. Further, various applications of the Bluetooth wireless technology are portrayed.
