Abstract:The problem of deciding the optimal sequence of diagnostic tests can be structured in decision trees, but unmanageable bushy decision trees result when the sequence of two or more tests is investigated. Most modelling techniques include tests on the basis of gain in certainty. The aim of this study was to explore a model for optimizing the sequence of diagnostic tests based on efficiency criteria. The probability modifying plot shows, when in a specific test sequence further testing is redundant and which costs are involved. In this way different sequences can be compared. The model is illustrated with data on urinary tract infection. The sequence of diagnostic tests was optimized on the basis of efficiency, which was either defined as the test sequence with the least number of tests or the least total cost for testing. Further research on the model is needed to handle current limitations.

Generalize Information

Given the trends in the modern world, as well as the rapid growth of digitalization, it is safe to say that it will inevitably affect almost all areas of human life and activities. Dmitriev’s English dictionary defines the word readiness: «It is a state where everything is done to start doing something.» Accordingly, an assessment of the company’s readiness to integrate modern digital technologies will identify opportunities, risks and threats, strengths and weaknesses of the enterprise, as well as to formulate a list of initial measures that need to be implemented. Thus, there is an urgent need to find an answer to the following questions: «How (by, what criteria and indicators) to measure readiness?», «What are the approaches to readiness assessment?» The purpose of this article is to develop a model and algorithm to assess the company’s readiness to integrate modern digital technologies. Modelling techniques were used to achieve this goal, as well as to analyze and generalize information. As a result of the research, a model for assessing the company’s readiness to integrate modern digital technologies has been developed and tested, based on the quality management model presented in the ISO 9000 series standards. A particular example shows how to use it and what it ultimately allows you to see and evaluate.

Near Future

We consider the paper by Brugnot and Pochat (1981), which describes a one-dimensional model applied to a snow avalanche. The main advance made here is the introduction of the second dimension in the runout zone. Indeed, in the channelled course, we still use the one-dimensional model, but, when the avalanche spreads before stopping, we apply a (x, y) grid on the ground and six equations have to be solved: (1) for the avalanche body, one equation for continuity and two equations for momentum conservation, and (2) at the front, one equation for continuity and two equations for momentum conservation. We suppose the front to be a mobile jump, with longitudinal velocity varying more rapidly than transverse velocity.We solve these equations by a finite difference method. This involves many topological problems, due to the actual position of the front, which is defined by its intersection with the reference grid (SI, YJ). In the near future our two directions of research will be testing the code on actual avalanches and improving it by trying to make it cheaper without impairing its accuracy.
