Dynamic Cost Reduction Through Process Improvement in Assembly Networks

W consider a decentralized assembly system in which a buyer purchases components from several first-tier suppliers. We examine the dynamics of suppliers’ investments in cost-reduction initiatives over the life cycle of a product under different procurement approaches. We model the suppliers’ investment decisions under cost-contingent contracts, with wholesale prices determined on the basis of t...

Process Innovation and Product Quality Improvement in a Dynamic Monopoly

We investigate the optimal R&D portfolio of a single-product monopolist investing in cost-reducing activities accompanied by efforts improving the quality of its product. There emerges that the firm’s relative incentives along the two directions are conditional upon market affluency, measured by consumers’ willingness to pay for quality, and R&D efforts are complements at equilibrium. We also p...

Building a Case for a Dynamic Requirements Process Improvement Model

Software requirements management is a volatile and dynamic process that requires continuous requirements process improvement in order to arrive at adequate requirements. However, there is interdependence amongst the processes themselves that leads to requirements managers‘ inability to achieve satisficed requirements for the intended software system. As a result, several software projects have ...

Process capability improvement of an engine connecting rod machining process

Statistical process control is an excellent quality assurance tool to improve the quality of manufacture and ultimately scores on end-customer satisfaction. SPC uses process monitoring charts to record the key quality characteristics (KQCs) of the component in manufacture. This paper elaborates on one such KQC of the manufacturing of a connecting rod of an internal combustion engine. Here th...
