Decision Making: Traditional Method

Decision Making: Traditional Method

The process of hypothesis testing based on the traditional method includes calculating the critical value, testing the value of the test statistic using the sample data, and interpreting these values.
First, a specific claim about the population parameter is decided based on the research question and is stated in a simple form. Further, an opposing statement to this claim is also stated. These statements can act as null and alternative hypotheses, out of which a null hypothesis would be a...

Decision Making

Decision Making

Decision-making is a fundamental cognitive process that involves evaluating alternatives and selecting among them. This process can range from simple choices, such as deciding what to wear, to complex decisions, like choosing a major in college or a career path. The complexity of the decision often dictates the approach we use, which can be broadly categorized into two types: automatic and controlled decision-making.
Automatic decision-making is fast, intuitive, and relies on gut feelings...

Stereotype Content Model

Stereotype Content Model

The Stereotype Content Model (SCM) was first proposed by Susan Fiske and her colleagues (Fiske, Cuddy, Glick & Xu, 2002; see also Fiske, 2012 and Fiske, 2017). The SCM specifies that when someone encounters a new group, they will stereotype them based on two metrics: warmth—or that group’s perceived intent, and how likely they are to provide help or inflict harm—and competence—or their ability to carry out that objective. Depending on the warmth-competence categorization, a person will feel...

Decision Making: P-value Method

Decision Making: P-value Method

The process of hypothesis testing based on the P-value method includes calculating the P- value using the sample data and interpreting it.
First, a specific claim about the population parameter is proposed. The claim is based on the research question and is stated in a simple form. Further, an opposing statement to the claim is also stated. These statements can act as null and alternative hypotheses: a null hypothesis would be a neutral statement while the alternative hypothesis can have a...

Area of Science:

Data Science
Artificial Intelligence
Operations Research

Background:

Traditional product evaluation systems lack adaptability due to fixed indicators and subjective weighting.
Dynamic market demands require more sophisticated and data-driven evaluation methods.
Existing frameworks struggle to integrate qualitative user feedback with quantitative product data effectively.

Purpose of the Study:

To propose a novel data-driven product evaluation framework.
To enhance product evaluation systems by integrating user-centered demand characteristics.
To provide a robust foundation for product design optimization and differentiated strategy formulation.

Main Methods:

Latent Dirichlet Allocation (LDA) for extracting latent themes from user reviews to build a multi-dimensional indicator system.
Fuzzy Analytic Hierarchy Process (FAHP) for quantifying qualitative indicators and forming an initial judgment matrix.
Particle Swarm Optimization (PSO) for global optimization and bias reduction in expert judgments.

Main Results:

A data-driven framework was developed and empirically validated using smartwatch data.
The framework successfully integrated user-centered demand characteristics into product evaluation.
Comprehensive and adaptable product evaluation results were achieved, demonstrating feasibility and effectiveness.

Conclusions:

The proposed framework offers a significant improvement over traditional product evaluation systems.
It effectively combines demand insights with market adaptability for better product development.
Provides a robust theoretical and methodological foundation for optimizing product design and strategy.
