Statistical analysis of models for punching resistance ensuring

Kalická Jana, Minárová Mária, Halvoník Jaroslav, Majtánová Lucia

Journal of Automation Mobile Robotics and Intelligent Systems

2019

Vol. 13, No. 3

49--55

In this paper the statistical assessment of the models that ensure the safety of the reinforced concrete slabs is fo cused. The investigation results in choosing the best mo del as the one that can aspire to become normative for European Union after 2020. Authors dispose with a suffi cient number of data yielded from experimental tests. Ha ving input geometrical and physical parameters of each experiment at hand, the corresponding theoretical value is computed by using three formulas provided by three models involving the same inputs. Case by case, the ratio between measured and theoretical value reveals the safety immediately. This ratio stands as the one parametric dimensionless statistical variable which is analysed after wards. Due to statistical parameters evaluation and in accordance with engineers a new model was suggested, statistically verified and nominated as the normative one.

Problem obiektów nietypowych w badaniach taksonomicznych

The article is related with the problem of the influence of untypical objects on classification results in taxonomic research. It is proposed to construct patterns on the basis of first and third quartiles. In a consequence the influence of untypical objects on a synthetic measure value for other objects can be reduced.

Group decision making with multi-objective optimization

Brauers W. K.

Foundations of Computing and Decision Sciences

2008

Vol. 33, No. 2

167-179

"Group Decision Making with Multi-Objective Optimization and with multiple stakeholders" forms the core of the problem to be discussed. Stakeholders mean everybody interested in an issue. In a stakeholder society the decision-maker is not replaced by different decision-makers but by a complete set of stakeholders. Of course, a problem exists with convergence of their opinions. For daily operations a delegate will obtain delegation for decision making. For principal judgments such as for strategic decisions the convergence of opinions of the stakeholders is essential. This convergence is not reached with face to face meetings, but with nominal methods, in which face to face conflicts are left out. Delphi and Nominal Group Technique are recommendable nominal methods to be discussed. As an illustration two case studies are developed.
