Decision Overview

Compare parking zones using availability, walking distance, customer priority, occupancy pressure, and operational fit.

Compare eligible zones for the same visitor. Keep customer priority consistent for that visitor. Confirm accessibility, permit, vehicle-size, and availability requirements before ranking; this demo does not reserve a space.

Catalog decision: AUTO-PARK-002. Sector: Parking Lot Management. Samples are fictional, not operational advice or production observations.

5-Minute Quick Path

1. Review the three candidates in the interactive showcase.
2. Start with the first working Business Data request, or send Prepared Criteria when values are already calculated.
3. Inspect the ranking and rerun with changed inputs or AHP priorities.

Criteria and Scales

Use raw values in the published units. The engine normalizes them. AHP changes importance, not the direction or scale of an input.

Data Preparation Guide

Business records → input schema → mapping profile → canonical criteria → ranking.

Use mapping profile parking-lot-manageme-recommend-parking-zone-auto-park-002 version 1.0.0. These records contain business assessments as well as measurements; this profile renames and reshapes them, but does not infer scores from free text. Govern rating and scoring rubrics before production use.

The showcase collects Prepared Criteria directly. Its sample values match both downloadable request modes below.

Understanding the Result

Verified local computation, not a hosted API response. The repository TOPSIS engine ranked these exact samples in-process. TOPSIS scores are relative closeness coefficients, not probabilities or confidence percentages.

Winner: ZONE-B. Download computation and AHP verification.

Check candidate eligibility and input evidence before acting. Adding or removing candidates can change normalization and the ranking. The showcase displays the actual service response, which may differ when the deployed catalog or configuration differs.

AHP Weights and Sensitivity

Open the paired showcase, choose “Help me generate weights (AHP)”, complete every comparison, and generate consistent weights before running. Option scores describe performance; weights express importance. Read the explanation.

Change one judgment or one measured input at a time, regenerate weights if needed, and compare the winner and score gap. A single unchanged winner is not a formal stability guarantee.

Profiles and Scenarios

The baseline uses balanced and scenarioId: null. Retrieve the deployed decision definition before selecting another profile or named scenario; never assume that “standard” exists. AHP does not override eligibility or safety requirements.

Run the Request

Use either JSON download with your existing authenticated API client. Endpoint and authentication details are in the API Guide. This browser-origin example calls the portal proxy, whose service connection must be configured:

const request = await fetch('/examples/auto-park-002/business-data-request.json').then(r => r.json());
const response = await fetch('/decisioq-decision-api-proxy.ashx?operation=execute', {
  method: 'POST', headers: {'Content-Type': 'application/json'},
  body: JSON.stringify(request)
});
const result = await response.json();
if (!response.ok) throw new Error(JSON.stringify(result));
console.log(result);

For validation errors, check canonical IDs, required values, units, and current catalog ranges. A transport error is not a decision rejection.
