Novotný, Jiří The category of Pawlak machines. (English) Zbl 0574.68047 Czech. Math. J. 32(107), 640-647 (1982). The paper is concerned with the study of the category whose objects are Pawlak machines and where morphisms are simulations. Two problems are investigated: 1) necessay and sufficient conditions for the existence of simulations for given two machines; 2) the description of the studied category.
