Abstract

Purpose

This paper aims at exploring the challenges of introducing a model integrating the Cost of Quality (COQ) into the modeling of a supply chain network.

Design/methodology/approach

This paper introduces a comprehensive supply chain model that minimizes a series of costs, in which COQ is integrated.

Findings

The scenario of incorporating COQ in supply chain network design will ensure the lowest overall cost, because it reduces the probability of defects and hence the probability of additional cost which might be due to corrective action.

Practical implications

With many industries today on the quest of improving their quality systems, finding ways to reduce nonconformities and failure of products is crucial. In industries such as the aerospace industry, the variable production cost is high; hence producing extra parts to compensate for defectives would be a costly option.

Originality/value

While COQ is a very good indicator of how much poor quality is costing a company, no work has been published in regard to integrating COQ into supply chain modeling.
