“…Islam [11] developed certain techniques to extract the underlying weights from different types of pairwise comparison matrices in the framework of analytic hierarchy process. Ramanathan and Ganesh [19] proposed a simple and appealing eigenvector-based method to intrinsically determine the weightages for group members using their own subjective opinions and also its superiority over other methods. Prabhu and VizayaKumar [18] illustrated the use of fuzzy hierarchical decisionmaking (FHDM) for steel-making technology considering the Indian conditions.…”

The present study illustrates the application of analytical hierarchy process (AHP) to a decision-making problem. AHP is a popular and powerful method for solving multiple criteria decision-making (MCDM) problems. An attempt is made here to initialize the use of multicriteria decision-making methods for ranking alternatives that curb student absenteeism. Through the expert opinions, the criteria that cause student absenteeism are identified and the criteria hierarchy was developed. The relative importance of those criteria for Indian environment is obtained through the opinion survey. Alternatives that curb student absenteeism in engineering colleges like counseling, infrastructure, making lecture more attractive, and so forth were collected from literature, journals' surveys and experts' opinions. Alternatives are evaluated based on the criteria, and the preferential weights and ranks are obtained. The experts' opinions are validated by Saaty's inconsistency test method. "Involvement of parents" is the best alternative given by the group of experts. Parents have to know their ward's day-to-day progress in college. The second best alternative is "counseling," as many criteria that cause student absenteeism are reduced by counseling.

“…The weights that are assigned to the arithmetic mean represent the relative significance of the SMEs and/or methods. The SMEs could either assign a weight to each other (Ramanathan and Ganesh 1994), or SMEs with lower matrix inconsistency ratios could be assigned higher weights (Cho and Cho 2008), or one SME could act as a supra decision maker and assign weights to others based on their merits. However, as these conditions were not applicable for this research, equal weights were assigned to all SMEs and methods.…”

This research paper aims at developing a triplex multi-criteria decision model to achieve an optimum allocation of resources to a portfolio of oilfields based on a number of criteria that pertain to the oilfields' technical and contextual characteristics. It also offers an approach for validating the prioritization results generated by the methods used through a two-dimensional test that compares the internal and external prioritization stability of three multi-criteria decision making (MCDM) methods against a conventional Intuitive approach. The MCDM methods used include Analytic Hierarchy Process (AHP), Preference Ranking Organization METHod for Enriched Evaluation (PROMETHEE), and Technique of Order Preference Similarity to the Ideal Solution (TOPSIS). The internal and external consistency testing results are outlined in nine possible scenarios through which a conclusion is derived confirming the competitive advantage of MCDM methods.

The globalization of suppliers and personalization of customers require new manufacturing strategy for environmental issues, region's special regulation and energy besides manufacturing factors from manufacturers. In this study, green factory is defined as a manufacturing floor that reduces waste elements such as extra work, energy, time and cost through quickly responding to external uncontrollable changes like a regulation, due date and supply. Therefore, the green factory should respond by establishing and implementing strategies for controlling their production volumes, changing their dispatch rules, adjusting their work schedules, increasing and decreasing the number of their machines and workers based on their own internal data and capacities, and other measures. To achieve such objective, manufacturing companies should realize a manufacturing intelligence that can visualize their shop-floor data, and detect and solve problems at the business planning level. In this study, an agile operations management (AOM) system that can quickly respond to field problems was developed for manufacturing intelligence. The AOM system refers to a system that collects internal data, monitors such data in real time, immediately detects problems, if any, and provides solutions to the detected issues within the shortest time.
