报告题目：Minimal-point Design for Order of Addition Experiment
In Fisher (1971), a lady was able totell whether the tea or the milk was first added by tasting. This is probablythe first popular order of addition experiment. In general, there are mrequired components and we hope to determine the optimal sequence for addingthese m components one after another. Knowing the optimal order ofaddition among components related in production is crucial. Order of addition,as an important factor affecting practical life, is involved in many areasincluding medical, food and film industry. However, references on this subjectare rather primitive. In this talk, we provide some properties of the pair-wiseordering designs to study the orders of addition. A construction method for theminimal-point order of addition designs is proposed. It is shown thatminimal-point order of addition designs can save significant amount of costwith higher relative D-efficiencies. Simulative studies are included toillustrate the ability of the minimal-point order of addition designs todistinguish the optimal orders of addition among components.
