Wedm Process

The surface measures of machined titanium alloys as dental materials can be enhanced by adopting a decision-making algorithm in the machining process. The surface quality is normally characterized by more than one quality parameter. Hence, it is very important to establish multi-criteria decision making to compute the optimal process factors. In the present study, Taguchi–Grey analysis-based criteria decision making has been applied to the input process factors in the wire EDM (electric discharge machining) process. The recast layer thickness, wire wear ratio and micro hardness have been chosen to evaluate the quality measures. It was found that the wire electrode selection was the most influential factor on the quality measures in the WEDM process, due to its significance in creating spark energy. The optimal arrangement of the input process parameters has been found using the proposed approach as gap voltage (70 V), discharge current (15 A) and duty factor (0.6). It was proved that the proposed method can enhance the efficacy of the process. Utilizing the computed combination of optimal process parameters in surface quality analysis has significantly contributed to improving the quality of machining surface.

Decision making is an individual activity that is directly involved in obtaining and using the goods offered. Promotion is one of the variables in a marketing mix that is very important to be implemented by a company in marketing its products or services, thus influencing consumers to make purchasing decisions. The quality of the product can also affect consumers in making purchasing decisions. This study aims to analyze the effect of product quality and promotion on purchasing decision of Melon fruit. Population and sample of research is purchasing or buyer from consumer of PT. Syafina Niaga as many as 30 companies and sampling methods using saturated sampling techniques as well as analysis used with regression analysis. The results showed that there is a significant influence between product quality and promotion of purchasing decisions.

Responsible Tourism

While sustainable tourism and responsible tourism share commonalities of guiding principles, responsible tourism places more emphasis on the behaviors of individual actors. However, little is known about how responsible tourists' behaviors are reconciled by their attitude toward tourism products' economic, cultural, and environmental contribution to a destination. This study explores the role of the tourists' attitude toward mariculture and perception of its benefits within the context of their travel decision-making process. Framed with the theory of planned behavior, this research examines tourists' perception of shellfish mariculture in relationship to their subjective knowledge about mariculture, attitude toward product quality of mariculture, and intention to be involved in marine tourism. This study suggests that the perception of benefits of the product are important considerations when tourists decide their travel activities in coastal destinations.

Best Worst Method

Choosing the best schools from a group of schools is a multi-criteria decision-making (MCDM) problem. In this paper, we have represented a method that uses the fusion of two multi-criteria decision-making methods, Best–Worst Method (BWM) and Analytic Hierarchy Process (AHP), to rank some of the user preferred alternatives. The system considers the choice of the user and the quality of the alternatives to rank them. User preferences on the criteria are taken as inputs in the form of best–worst comparison vectors to measure the choice of the user. These values are applied to calculate the numeric weights of each of the criteria. These weights reflect the preference of the user. A dataset of secondary schools in Bangladesh has been compiled and used for automatic quantitative pairwise comparison on the alternatives to calculate the score of each alternative in every criterion, which reflects its quality in that criterion. These scores are calculated using AHP. The weights of the criteria as well as the scores of these alternatives in those criteria are then used to calculate the final score of the alternatives and to rank them accordingly. An extensive experimental analysis and comparative study is reported at the end of this paper.

The Impact

Purpose The purpose of this paper is to use multi-criteria decision-making methods to assess environmental quality of the Organization for Economic Co-operation and Development (OECD) countries. Design/methodology/approach Weights of criteria are determined by means of entropy weight method. VIKOR method is used to rank different OECD countries based on their environmental quality. Findings The results show the best and the worst environmental quality of different OECD countries. The top five countries of environmental quality are Spain, Israel, Belgium, Japan and the USA. These countries have the best quality of environment. By contrast, the worst five countries of environmental quality are Iceland, Australia, New Zealand, Canada and Chile. Originality/value The findings have implications regarding environmental quality. The results suggest that governments should engage in policy-making that improves their environmental quality. Specifically, those having poor quality of environment should protect the environment and reduce the negative impact on environment. For example, reduce emission of CO2 to lessen the impact of climate change, improve the quality of air and water, reduce waste generation, increase biodiversity and enhance forest resources. Improvement of environmental quality will improve our social and economic life as well as health conditions.
