run()

Description:

Try to run the AHP analysis process. The result information will be returned.

Parameters:

nil

Return Object properties:

Property	Type	Description
error	ContextError	The Context Error object if found, or null otherwise.
rankingMatrix	number[][]	The processed ranking matrix. The row entry represent each item's scores. Each entry in the row represent that item's score on a certain criteria.
itemRankMetaMap	object	The metadata(e.g: CI, RI, CR) for each criteria perspective item ranking matrix.
criteriaRankMetaMap	object	The metadata(e.g: CI, RI, CR) for criteria ranking matrix.
rankedScoreMap	object	The overall computed ranking score for each item

Example:

......
let analyticContext = ahpContext.run();
for(let key in analyticContext){
    console.log(`${key}: `, analyticContext[key], '\n');
}

Console output
