We develop a model that reveals the preservation value of maintaining connectivity within socio-ecological system (SES). By means multiplex network, built from layers composing sustainability Venn diagram, we define two measures inter- and intra-layer connections. Most policymakers researchers have tended to assume all elements an SES are unconditionally connected, which implied dimensions sust...

In this paper, we focus on a continuously deteriorating critical equipment which its failure cannot be measured by cost criterion. For these types of systems like military systems, nuclear systems, etc it is extremely important to avoid failure during the actual operation of the system. In this paper we propose an approach which constrains failure probability to a pre-specified value. This valu...
