README

AHPd is a 100% objective, multi-criteria decision-making system, representing a modern, data-driven evolution of the classic Analytic Hierarchy Process (AHP) method.

Unlike traditional AHP, AHPd eliminates subjective judgment. It uses real, measurable data to generate business decisions that are consistently auditable, mathematical, and justifiable.

🎯 Strategic Advantage: Bias-Free Decisions

In complex and highly regulated environments, subjectivity is the biggest risk. AHPd was built to eliminate this risk.

The AHPd system provides a quantitative framework for comparing alternatives—be it products, projects, suppliers, or strategies—based on their quantitative attributes (price, performance, quality, resource consumption, etc.).

🧠 How AHPd Works: Simple Process, Auditable Result

AHPd automatically transforms raw data into strategic insights without the need for data pre-processing or normalization.

1. Define Preferences (Minimum Input): Specify the criteria and indicate whether you want to maximize or minimize each one (e.g., "Maximize Quality," "Minimize Price").
2. Provide Raw Data: Input the quantitative data for all options being compared. Data can be passed exactly as it exists in your system.
3. AHPd Automatic Calculation:
   • The system analyzes the statistical spread of values across all options.
   • Automatically assigns the weight of importance to each criterion based on this spread.
   • Determines the relative performance (priority) of each alternative.
4. Final Ranking: The output is a clear, auditable percentage ranking, showing which alternative is best and why.

📊 Intuitive Example

Consider a device purchase decision. The user only needs to indicate whether a lower "price" is better or a larger "battery" is better.

➡️ AHPd Ranking Result:

• Phone D — 33.6% (Winner)
• Phone B — 25.38%
• Phone C — 26.1%
• Phone A — 14.93%

The screenshot below intuitively shows the results, allowing you to see precisely how much each feature (criterion) contributed to the final ranking score. This visually validates the weights calculated by AHPd.

💡 Explanation: Phone D (33.6% final score) won because it was the lowest-priced alternative. AHPd calculated that the 'price US$' criterion had the greatest statistical disparity among all candidates, assigning it a massive weight of 46.0% in the decision model. This resulted in Price having a 33.3% contribution to Phone D's total score, outweighing the contribution of any other single criterion for all other alternatives.
