Abstract: A systematic design construction method is proposed for cost-efficient order-of-addition (OofA) experiments and its corresponding statistical models for analyzing experimental results. Specifically, these designs consider the effects of two successive treatments. Each pair of level settings from two different factors in our design matrix appears exactly once to achieve cost-efficiency. Compared to designs in recent studies of OofA experiments, this design can conduct experiments of one or more factors, so practitioners can insert a placebo or choose different doses as level settings when this design is used as their experimental plans. An experimental analysis based on this design performs better than those based on the minimal-point design and Bayesian D-optimal design with pairwise-order modelling in identifying the optimal order.
