Dynamical and system-wide properties of linear flow-quantified food webs

Link tracking: Quantifying network flows from qualitative node–link digraphs

“…Nodes can be identical but links and therefore webs variable in realistic cases. Buzhdygan (2008) and Buzhdygan et al, (2012) demonstrated this for several hundred species, many the same, arrayed in 31 pastoral food webs in Ukraine. All the described webs were different (variable structure).…”

Understanding the mechanism of food waste management by using stakeholder analysis and social network model: An industrial ecology perspective

“…In the past, most studies concentrated on nondirection binary (Hicks et al, 2013;Navia et al, 2010;Yang and Zou, 2014). Currently, attention is turning to the direction of assignment value study (Buzhdygan et al, 2012;Dell'Apa et al, 2013;Lienert et al, 2013). However, only a few of works studied the waste management issues by applying SA and SNA methods.…”

“…Harary (1969) improved the model by using the conceptual graph including nodes (points) and relationships(lines) between nodes. In recent years, SNA model were applied to study the natural resource management, such as water governance, marine ecosystem and food chains (Navia et al, 2010;Stein et al, 2011;Buzhdygan et al, 2012;Dell'Apa et al, 2013;Hicks et al, 2013), attempting to integrate this sociological tools into the interdisciplinary researches. In the early stage, the theory was mostly based on manual computations and drawings; in the 1990s, with the development of computer science, a higher visual degree was achieved and the visual matrix was used to portray the entire system network, enabling the studies not only on individual network properties, but also on full social network properties and the network structures.…”
