Compares the bullwhip properties of a vendor managed inventory (VMI) supply chain with those of a traditional “serially-linked” supply chain. The emphasis of this investigation is the comparative impact the two structures have on the “bullwhip effect” generated. Particular attention is paid to the manufacturer’s production ordering activities as demonstrated using a simulation model b…
This paper aims to provide an answer to the important question of how can accurate assessment of supply chain practice and performance be conducted? By conducting audits across a sample of value streams it is thereby possible to identify the components of “good practice” via evidencebased procedures.
The aim of this article is to provide a concise methodology for the design of a widely used class of decision supply systems (DSS) which will enable precise control of bullwhip variance and inventory variance induced within a supply chain echelon. Design/methodology/approach – The study exploits recent research that derived analytical formulae for calculating these performance metrics germane…
The Law of Industrial Dynamics ensures that if a production control system can amplify then it will surely find a way of doing so despite the best efforts of production schedulers to take corrective action. In fact, practical studies show that such human intervention frequently aggravates the situation with both stock levels and order rates fluctuating alarmingly. The solution is to design an e…
Real world supply chains differ not only in their current standard of performance, but also in the most effective actions required to move each towards world class supply. A generic approach for the identification of the appropriate re‐engineering programmes based on the uncertainty circle principle is presented. A total of 20 European automotive supply chains have been analysed via a “quic…
Speed of response to customer demand has long been recognized as a key attribute to business success since customer loyalty can be won or lost on product availability. With everyone implementing lean manufacturing philosophies, companies additionally need to become smart chain managers and ensure continuous improvement to stay competitive. Exploits further the concept of the “seamless supply …
