Estimating efficiency of search operationsThis article deals with the search operations. A set of numerical evaluation criteria of the effectiveness
of search operations is introduced. The purpose of studies is to suggest efficiency criteria of
search operations and develop a measurement method. This article is about special the search system.
The search system includes the block of object indexing, the block of recommendatory list processing,
the block of searching, the block of searching array realized, the block of recognition, the
block of archive of objects. Four properties were detected. The average number of similar objects
in the list of recommendation is an important indicator. Estimates of the effectiveness of search operations
were obtained. Two effectiveness indicators presented this estimate: probability of the correct
response to the search inquiry, average length of the recommendatory list, which is given by the
search block for the human operator making the final decision. In this paper, the particular attention
is given to indicators: probability of the correct response to the search inquiry and average length
of a recommendatory list. The algorithms were applied. Algorithm is characterized by two probabilities:
probability of missing a target and false alarm probability. Study of these estimates was done
and the experimental results were obtained. These results are used for some information systems
for making decisions in criminalistics. It is offered to use a special factographic information retrieval.
The results were successfully protected by various patents. Further, it is planned to get and explore
in details one remaining evaluation of the effectiveness. Namely, the average number of comparison
operations that are implemented by the search block.

Sequential analysis for testing of the human operatorThis article deals with the sequential analysis for testing of the human operator. A set of important
criteria (indicators) of the effectiveness of the human operator is introduced. The purpose of studies
to obtain an estimate efficiency of the human operator. This article is about special the information
system. The information system includes: the block of object indexing, the block of recommendatory
list processing, the block of searching, the block of searching array realized, the block of recognition,
the block of archive of objects and the human operator too. The search of this indicator is done. The
average number of errors for the human operator is important. Estimates of the effectiveness of the
human operator were obtained. Sequential analysis for testing of the human operator was used. The
experimental results were obtained too. The obtained results are used for some information systems
for making decisions in criminalistics. It is offered to use a special factographic system. The results
were successfully protected by various patents. Further, it is planned to get and explore in details
another method for testing of the human operator.
