Designing modules of system dynamics in decision support systems by A. B. Sorokin, L. M. Zheleznyak, D. V. Suprunenko, V. V. Kholmogorov

“…When creating models of system dynamics, the basic construct at the design stage is the representation of the process under study in terms of a causal relationship consisting of a positive feedback loop and a negative feedback loop. The construction of a model of a dynamic environment can experience a number of difficulties in using feedback. …”
