[ 1 ] - On the Bullwhip Effect Measure in Supply Chains with VAR (1) Demand Process
In this paper, a two-echelon supply chain, which includes two products based on the following considerations, has been studied and the bullwhip effect is quantified. Providing a measure for bullwhip effect that enables us to analyze and reduce this phenomenon in supply chains with two products is the basic purpose of this paper. Demand of products is presented by the first order vector autoregr...
[ 2 ] - بررسی تاثیر فرسایش ابزار بر روی نمودار کنترل نسبت اقلام معیوب
Statistical process control charts are generally designed assuming that when the process is in control the observations are independent and identically distributed (i.i.d.) over time. However, the assumption of independence is easily violated when a process inherently generates auto correlated observations. When traditional control charts are applied to such processes then the false alarm rate...
