In contrast to the classical discrete choice experiment, the respondent in a rank-order discrete choice experiment, is asked to rank a number of alternatives instead of the preferred one. In this paper, we study the information matrix of a rank order nested multinomial logit model (RO.NMNL) and introduce local D-optimality criterion, then we obtain Locally D-optimal design for RO.NMNL models in...

The development of 3D printable cement-based materials is a complex process with variety competing objectives. compositions formed are far more than in conventional concrete, increasing the difficulty designing mixtures for concrete printing. As number mix design increases, workload increases exponentially during process. In this study, D-optimal experimental method employed to reduce experimen...
