Construction of an optimal design

Description

Construction of an optimal design balanced for first order of carry-over effect.

Usage

optimaldesign(nbPanelist, nbProd, nbProdByPanelist, nbPanelistMin = nbPanelist,  ordre = TRUE, weight = 0.5, graine = Sys.time(), nbDesignProd = 10, nbDesignOrdre = 50, matEssImp = NA )

Arguments

nbPanelist Maximum number of panelists
nbProd Number of products
nbProdByPanelist Number of products that each panelist will evaluate
nbPanelistMin Minimum number of panelists who will evaluate the products
ordre Boolean, if TRUE the order of presentation of the product to the panelist is given
weight Importance of the rank and of the carry-over effect. From 0 to 1, if 0 the design will only take into account the carry-over effect (and not the rank effect).
graine initialization of the algorithm
nbDesignProd Number of iteration of the algorithm to affect the products to the panelists
nbDesignOrdre Number of iteration of the algorithm for the rank of presentation
matEssImp Matrix of the imposed experiments

Value

List with

design Design with the products evaluated by each panelist
rank Design with the products evaluated by each panelist and with the rank
