L-Fuzzy Set Model of the Optimal Therapy When Diagnosis is Known

In this paper we try to resolve the problem of decision of the optimal therapy when the diagnosis is known. In papers [2], [3], [4], [9],[10], [11] the mentioned problem was treated by methods of fuzzy sets theory. Fuzzy sets were considered there as mappings from a set to [0,1] real interval. Here this problem has been considered using fuzzy sets from a more general point of view, as mappings whose co-domain is a special lattice valued monoid. The model developed in this paper is an improvement of the one given in [5]. In the same time it is an anticipatory model since it predicts efficiency of all possible drugs to the disease in question and it suggests the optimal therapy for every patient.
