Content available Preliminary approach to modelling eutrophication - anthropopressure impact on sea water quality
Bogalecka Magdalena
Safety and Reliability of Systems and Processes
|
2023
|
Summer Safety and Reliability Seminar 2023
19--31
EN
The chapter is devoted to the problem of eutrophication. Methods and parameters for its assessment are described. Furthermore, the eutrophication of the Baltic Sea is discussed in detailed. Finally, the semi-Markov model of the eutrophication process is proposed, and its characteristics are determined.

Content available Multi-state approach to food packaging material quality and consumption safety analysis
Bogalecka Magdalena, Morawska Magda
Safety and Reliability of Systems and Processes
|
2022
|
Summer Safety and Reliability Seminar 2022
35--50
EN
The food packaging material and its quality assessment based on permeability, tensile strength, swelling, transmittance, and biofilm formation are discussed in this chapter. The semi-Markov model of food packaging material quality change process is introduced and its characteristics are determined. Next, the safety and resilience indicators are proposed for multi-state analysis, identification, prediction and optimization of packaged food product consumption safety.

Content available Modelling process of municipal wastewater quality - backgrounds and preliminary application
Bogalecka Magdalena, Dereszewska Alina
Safety and Reliability of Systems and Processes
|
2022
|
Summer Safety and Reliability Seminar 2022
17--34
EN
The probabilistic model of municipal wastewater quality process is proposed in the chapter. The methods of its characteristics and parameters statistical identification and prediction are presented. Next the proposed model is practically applied to examine and characterized the quality of the municipal wastewater collected in the exemplary sewage treatment plant.

Content available Semi-markovian approach to modelling air pollution
Bogalecka Magdalena
Safety and Reliability of Systems and Processes
|
2021
|
Summer Safety and Reliability Seminar 2021
31--44
EN
The air pollution assessment based on concentration’s changes of sulphur dioxide, carbon monoxide, nitrogen dioxide, ozone, benzene, and particulate matter is discussed in the chapter. The semi-Markov model of the environmental pollution process is introduced and its characteristics are determined. Next the proposed model is practically applied to examine and characterized air pollution in Gdańsk (Poland) as the exemplary industrial agglomeration. The main parameters and characteristics of the air pollution process are determined, such as concentration states of particular kinds of air pollutants, the limit values of transient probabilities and the mean total sojourn times staying at the air pollutants’ concentration states, for the fixed time interval.

Summer Safety and Reliability Seminar 2021
181--206
EN
The safety and resilience indicators are proposed as crucial tools for analysis, identification, prediction and optimization of COVID-19 pandemic human safety and for minimization and mitigation of pandemic consequences.

Content available Modelling maritime critical infrastructure accident consequences with semi-Markov chain method
Bogalecka Magdalena
Safety and Reliability of Systems and Processes
|
2020

Summer Safety and Reliability Seminar 2020
33--49
EN
The probabilistic general model of critical infrastructure accident consequences consists of three particular models of semi-Markov processes such as: the process of initiating events generated by a critical infrastructure accident, the process of environmental threats coming from released chemicals that are a result of initiating events and the process of environmental degradation as a result of environmental threats. The general model of critical infrastructure accident consequences and procedure of its application to the maritime transport critical infrastructure understood as a network of ships operating at the sea waters is presented in the research. By using the statistical data coming from sea accidents reports, the general model is applied to the identification and prediction of the environmental degradation associated with ship accidents and chemical releases within the Baltic Sea. Moreover, the proposed model is applied to estimate the environmental losses associated with these accidents and the environmental degradation in the neighborhood area.
