The simplest type of UBMSS systems are those that analyse single ratios characteris-
ing a company. The most important of them include systems which analyse the NPV.
This type of systems is the simplest type of a UBMSS system, and an example of its
operation is presented below.
The formal grammar presented below has been proposed for the suggested
UBMSS system conducting an analysis based on the NPV:

where:

NO_ACCEPT, A, B, C

- the set of terminal symbols,

This publication is an attempt at defining a UBMSS system for the cognitive
analysis of investments on the basis of key financial indicator, which include NPV -
net present value (symbol: W1) (Fig. 8).

The analysis of economic ratios conducted in UBMSS systems allows the semantic
contents of the analysed data to be used to determine the nature of that data, its impact
on the current situation of the company and the extent of changes they cause to the
company and its environment taking into account the information currently possessed.
Such an analysis is possible due to semantic information contained in the analysed
data. Semantic information may relate to:
