Quantitative Assessment Framework for Product Value and Change Risk Analysis in Early Design Process
Bibliographic record
Abstract
The ever changing trends in current markets along with customers’ rising demands for quality require many companies to make frequent changes in their products. In this paper, a framework for a comprehensive Decision Support System (DSS) is described and illustrated with a simple example of a thermo-flask. The DSS aims to obtain an optimal balance between customer and enterprise satisfaction by taking into account different design decision attributes: customer requirements, cost and design risk. The system allows the recalculation of cost, value, effort and risk when engineering change occurs during the creation of new design solutions. The proposed DSS integrates House of Quality (HOQ), Functional Analysis System Technique (FAST), risk assessment and change propagation analysis to provide a view of the design process from product attributes and design risk to cost and effort. The goal is to increase product knowledge in the early stages of design, to calculate the effects of engineering change, and to support design engineers in decision making.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
