Abstract

Supply chain management is an innovative integrated management method for the supply chain with flows of objectives such as materials, information and cash. Among these flows, the information could be modified, distorted and delayed while being transacted in the supply chain. The modified, distorted, and delayed information increases variability of ordering amount of products or materials. Bullwhip effect is one of the phenomena showing increased variability in the supply chain. In this paper we develop a bullwhip effect measurement which could be applied to the inner company transactions under make-to-order manufacturing environment and to measuring the variability in the ratio of materials or finished goods delivered on time. The inventory impact caused by the modified, distorted and delayed information is also demonstrated using the proposed bullwhip effect measurement.
