Purpose: The purpose of this paper is to develop an optimization model to better allocate cost of quality (COQ) in the supply chain (SC). In addition, the paper provides a roadmap based on COQ that allocates limited given budget among the SC entities. Design/methodology/approach: This paper...

Purpose: The purpose of this paper is to explore the impact of the cost of quality (COQ) expenditure allocations on a capacitated supply chain (SC) network. Design/methodology/approach: This paper proposes a non-linear optimization model which integrates the opportunity cost (OC) (i.e. customer...
