The effect of base temperature variation on the heat transfer from unsteady state annular heat sink of cooling microelectronic device. Three types of the base temperature variation equations are taken in the present study. The Sine wave variation, Cosine wave variation & exponential variation of the base temperature. The finite element technique based on Galerkin method with axisymmetric rectan...

Failure mode and effects analysis (FMEA) is an analysis tool for identifying and preventing flaws or defects in products during the design and process planning stage, preventing the repeated occurrence of problems, reducing the effects of these problems, enhancing product quality and reliability, saving costs, and improving competitiveness. However, FMEA can only analyze one influence factor ac...

The fuzzy analytic hierarchy process (fuzzy AHP) and fuzzy decision making trial and evaluation laboratory (fuzzy DEMATEL) have been used to obtain weights for criteria and relationships among dimensions and criteria respectively. The twomethods could be integrated since it serves different purposes. Previous research suggested that the weights of criteria and the relationships among dimensions...

This study demonstrates how a decision-making trial and evaluation laboratory (DEMATEL) threshold value can be quickly and reasonably determined in the process of combining DEMATEL and decomposed theory of planned behavior (DTPB) models. Models are combined to identify the key factors of a complex problem. This paper presents a case study of a food and beverage information system as an example....

Financial supervision means that monetary authorities have the power to supervise and manage financial institutions according to laws. Monetary authorities have this power because of the requirements of improving financial services, protecting the rights of depositors, adapting to industrial development, ensuring financial fair trade, and maintaining stable financial order. To establish evaluat...

Supplier selection is considered as one of the most critical issues encountered by operations and purchasing managers to sharpen the company’s competitive advantage. In this paper, a novel fuzzy multi-criteria group decision making approach integrating quality function deployment (QFD) and decision making trial and evaluation laboratory (DEMATEL) method is proposed for supplier selection. The p...

The study proposed a maintenance rating program (MRP) in Taiwan which combines the methods of DEcision MAking Trial and Evaluation Laboratory (DEMATEL) and Analytic Network Process (ANP) to evaluate maintenance activities accurately. In the view of the provincial and county roads in Taiwan, DEMATEL was employed to compute the effects between criteria through experts’ interviews and questionnair...
