Processes related to the application of collective risk models
(Університет «КРОК», 2020) Taha, Mohamed Daab
There are many books, studies and research papers that show some basic findings in the mathematics of non-life insurance through the use of theoretical insurance operations. The insurance business has been described as a random and continuous process of time. This gives a more complex view of insurance mathematics and allows one to apply recent results from the theory of stochastic processes. The prevailing opinion about insurance mathematics (at least among mathematicians) is that it is rather dry and tedious matter because one interprets only momentarily and does not actually have any interesting structures. Nobody should takethis view at face value and it is fun to work with mathematical structures for non-life insurance. The possibility of obtaining absolutely accurate knowledge exists only in cases involving the determination of physical parameters of size, mass, force, etc.) of environmental objects and subject to the use of complex laboratory methods. In everyday life, knowledge about the future, which is influenced by a large number of factors that cannot be studied and predicted, is based on approximate estimates, which forms the concept of uncertainty.So the current script can also be interesting for those who don't necessarily want to spend the rest of their lives with an insurance company. These processes lie in this paper to introduce many other fields of applied probability theory, such as regenerative theory, alignment, stochastic networks, point process theory, application such as Poisson, Poisson's compound, and regenerative processes. Where the appropriate stochastic process has been called the Brownian movement, which deals with the modeling of claims that reach the insurance business, which advises on how much insurance premium should be paid to avoid bankruptcy (destruction) of the insurance company by this we mean a set of contracts or policies for similar risks such as auto insurance Certain cars, home theft or water damage insurance in single-family homes.
The impact of the covid-19 pandemic and Russia's war against Ukraine on the quality of life in the context of threats to global food security
(Університет «КРОК», 2022) Taha, Mohamed Daab; Liashenko, Oleksandra
Currently, threats to food security reach a global scale. To a large extent, this is caused by the full-scale invasion of Russia on the territory of Ukraine and the losses that occurred as a result of the war. In general, before the war, Ukraine supplied 10% of world exports of wheat, more than 15–20% of barley, and more than 50% of sunflower oil. After the Russian invasion, Ukraine restricted the export of some grains. According to the UN High Commissioner for Human Rights, Michelle Bachelet, due to Ukraine's war with Russia, the number of people with a lack of food will increase by 47 million during the year and will be almost 323 million by the end of the year. First of all, the term food security refers to the availability of food for people without any scarcity, and it is considered that food security is effectively achieved when a person is not afraid of or susceptible to hunger, and is used as a criterion to prevent food shortages or disruptions in the future in a few factors Such factors are considered dangerous, including drought and wars and other problems, if they threaten food security. Absolute food security is defined as the production of food in one country at a level equal to or even exceeding domestic demand and can sometimes be considered to achieve the concept of complete self-sufficiency. Indicators of relative food security relate to the state's ability to produce and supply what the population needs in the form of food in whole or in part. From this we conclude that the concept of food security refers to the need to provide the population with the necessary food products, which may depend on cooperation with other countries or only on self-sufficiency. The Covid-15 pandemic and the war have broken many chains of the global food security system, and as a result, there have been significant disruptions in the uninterrupted supply of food to consumers at reasonable prices. The methodology is based on the analysis of scientific problems according to the nature of the research object, based on such methods of scientific knowledge as direct (empirical) analysis and synthesis, induction and deduction, historical method. The results of the study relate to the presentation of the conceptof food security and the degree of influence on it by natural disasters and geopolitical conflicts, in particular the war between Russia and Ukraine, the study of individual indicators of Ukrainian exports that affect the food security of some Arab and African countries, as well as the volumes of production and exports in different periods . Such indicators show a brief overview of the importance of Ukraine as a "food-nurse" for some countries and the consequences that will occur if the supply of agricultural products from Ukraine is stopped from both large and small businesses.
The role of collective risk modeling processes and related applications in managing international insurance companies

Using a cost of living data for a comparison between maximum likelihood method and moment method for estimating gamma distribution parameters
(Університет «КРОК», 2020) Taha, Mohamed Daab
Widespread use of methods of probability theory and mathematical statistics in economics and practice requires a broader and more thorough training of specialists in various sectors of the economy in the field of their development of modern mathematical knowledge. Virtually all processes occurring in the organization of production, finance, marketing, banking, management, have elements of uncertainty, complexity, multiplicity, ie are characterized by chance. Therefore, it is very important to manage the economy is to establish patterns in random phenomena. The use of statistical methods of data processing makes it possible to identify real patterns that objectively exist in mass random phenomena. On the basis of such data processing it is possible to make a forecast of economic development with certain accuracy, to calculate the risks of economic activity, to predict crises and other socio-economic phenomena that are random.
