Table 3.1 Description of the decision making system (DMS) and the sub-units of the decision
making sequent procedure (DMSP) of Fig. 3.5
Sub-unit Description

VMD Visualization of the measurement data in the form of direct soft copy, discrete

distribution and statistical parameters

CSC Calculation of the statistical characteristics (mean, central second- and third-order

moments, asymmetry and excess coef cients, expression of the entropy, etc.)

SETDF Synthesis of the empirical and theoretical distribution functions

VP Valuation of the parameters used in the Neyman-Pearson and the sequential

procedures of the hypotheses decision

RUA Realization of the user access to all the functions of the decision-making system

VVAD Visualization of the accepted decision

DMSP-I DMSP input: α , ʲ , a,{x i }

AMLR Accumulation of measurements as the likelihood ratio

ET Evaluation of the thresholds A and B

CLRT Comparison of the likelihood ratio with the thresholds A and B

VSPS Visualization of the sequential procedure state

FTDP-
UQ

The FTDP unit query with respect to the form of f a (x) and the activation of the
appropriate knowledge base level

EV Evaluation of E m ; D m ; c

CPCSP Computation of the probability of completion of the sequential procedure

CTT Control of the task type for the choice between H 0 and H 1 taking the errors of the

first and second kind into consideration

MOI Management of the operative intervention to the functioning of the DMSP unit
