The study of the stability of many stochastic processes as Markov chains needs sometimes to use eigenvalues and eigenvectors of the transition matrix. This paper is an investigation on a methodology which computes fuzzy eigenvalues and fuzzy eigenvectors within the context of a fuzzy Markov chain transition matrix, under max-min composition.

This paper introduces the performance measures computation of a product form queueing network with fuzzy parameters. In this first study, we focus our objective to find the customers number and the customer sojourn time in the system at the stationary state. Values of these characteristics are provided. A didactical example is used to illustrate the process.

In this paper, Hölder, Minkowski, and power mean inequalities are used to establish Ostrowski type inequalities for s -convex functions via h -calculus. The new inequalities are generalized versions of Ostrowski type inequalities available in literature.

In order to estimate the average insurable pig numbers held by breeders, their monetary value, the ASF insurance premium in the event of adoption of the product, a survey was carried out from January 2 to April 10, 2021, among 63 pig farmers. from Mont Ngafula in Kinshasa, DRC to collect information relating to the construction of a future model of local management of this risk. The average insurable pig population owned by a breeder from Mont-Ngafula in Kinshasa is 8,571 ± 3.48 and this represents an average monetary value of 2.604 ± 1.092,87 with an average ASF insurance premium of 169.27 ± 71.03 $. The correlation matrix showed a strong link between the pig workforce, monetary value of the pig herd, ASF insurance premium, frankness and indemnification. The model of linear regression explains 77.09% of the link between the insurable pig population held by a breeder and the premium payable in the event of adoption of ASF insurance. The equation for the line is Y = 17.916 x + 15.709. The Multiple Correspondence Analysis (MCA) in turn shows that there are three variables that have a higher correlation for the management of this ASF and these are the level of study (0.65), the veterinary consultation (0.55) and the payment. of the PPA premium (0.42). The alignment of the first bisector for all variables suggests that they are normally distributed. Pig farmers complain about the lack of funding and support from the state services in charge of the pig sector.
