摘要：The article explores theoretical and methodical aspects of managing dual relationships that arise
between participants in logistic cooperation in the process of formation and functioning of supply
chains. The use of a behavioral approach to defining supply chains has allowed identifying and justifying
the priority role of behavioral factors that influence modern logistics entities and determine
the effectiveness and long-term satisfaction with logistics cooperation. Given the literature summary,
the study has classified types of cooperation in logistic activity and proved that among the behavioral
factors influencing the of logistical cooperation efficiency, the trust is of particular importance, which
remains a limitation, a bottleneck in the process of formation and development of dual relationships
in logistics chains. It is proposed to introduce a generic indicator, namely the level of confidence
in the supply chain to assess the social, economic and strategic aspects of logistics interaction. A
methodological approach to assessing the level of trust in logistic cooperation was adjusted based
on determining the composition of criteria that directly affect this indicator and using the expert
survey of supply chain participants. The study proposes to use the confidence indicator to form and
improve networks and supply chains, taking into account its value when constructing a generalized
outsourcing model.
