The paper considers a C# software package that implements algorithms of the local probabilistic-logical inference in algebraic Bayesian networks and the synthesis of their secondary structure. The package supports local network con- sistency verification and maintenance, priori and posteriori inference operations. In addition, two assembly algorithms for generating the set of minimal joint graphs and a usage example for one of them are presented. These algorithms provide algebraic Bayesian networks visualisation and are intended for structured entry data representation in GUI as well as for global evidence propagation and other probabilistic-logic inference operations implementation based on their local homologues.
