Evaluation of supply chain performance using delivery-time performance analysis chart approach
Abstract Variability reduction and business synchronization are acknowledged as keys to achieving timely deliveries in supply chain networks. The evaluation of delivery performance is a crucial component in the overall management and time control of a supply chain. This study uses lead time, delivery window and delivery performance chart (DPC) to measure the delivery performance of every stage in a serial supply chain. Lead time is an important delivery performance metric for organizations. DPC, which is integrated by the process capability indices (PCIs) and the concept of Motorola Six-Sigma, is proposed to provide several simultaneously visualized important features of delivery performance in a supply chain. We also consider the uncertainty of the estimated PCIs caused by sampling data and plot their lower confidence bounds (LCBs) in the DPC to measure the minimum delivery capability of each stage in the supply chain. Finally, a case study related to a supply chain of notebook industry is presented to d...
