DEW is an interactive tool for the construction of a wide range of experimental designs for comparative experiments useful in practical research.

Block designs for unstructured treatment sets

provides for a range of crossed and nested block designs for arbitrary unstructured treatment sets with arbitrary levels of replication.

Factorial and response surface designs with blocking

provides for blocked designs for arbitrary mixtures of categoric and numeric factors assuming a standard factorial model for the categoric factors and a polynomial model for the numeric factors and with unstructured control treatments added to blocks, if required.
