The modern logistics concept is reflected in the system of «supply chain management» of inventory resources in the field of mass and serial industrial production, focused on consumer markets. However, the processes of managing various resource flows at the stages of investment and construction and especially development projects “with an open completion date” to create and improve unique real estate objects for a specific customer were not covered by this concept. In this regard, the relevance of research was determined by the need to develop a special methodological approach to the phased management of resource-flow processes in the field of project management. Based on the results of “case studies”, such new concepts of the project and logistics sphere as the “environment” for managing strict alternation and implementation of their numerous organizational and technological stages throughout the life cycles of projects, phased transport and logistics “environments” for the functioning of individual stakeholders were introduced and methodologically substantiated based on the results of “case studies”. - management executors and stakeholders - carriers for the transportation of resource flows and phased design and logistics «eco-environments» of their interaction in the «business - ecosystem» of development projects as a whole. The purpose of these «case studies» was an eco-environmental methodological substantiation of the project-staged functioning and structural-functional interaction of stakeholders - executors of processes, operations and functions for managing resource flows and stakeholders - carriers for their transportation from the external resource environment of projects and for their numerous and strictly designated within the design organizational and technological stages. As well as the formation on this basis of a new eco-logistics concept - «management of the design-phased transport and logistics» relay race «of resource flows» of «open» development projects. The working hypothesis of the study consisted in the assumption of the possibility of substantiating the above-mentioned subject-object stage-by-stage design and logistics environments and eco-environments and, in general, a new eco-logistic concept of stage-by-stage management of flow processes for the full organizational and technological life cycle of «open» development projects. What will be a necessary condition for increasing the level of management efficiency of the «project-staged transport and logistics» relay race «of resource flows» and the stage-by-stage structural and functional interaction of project stakeholders. The study was based on well-known elements of general scientific methodology: modeling and formalization; systemic and structural-functional approach; model, structure and hypothesis, chaos, uncertainty and others. The application of specific scientific methodology consisted in the use of theoretical foundations and specific methods for conducting thematic design and logistics research. In particular, a phased analysis of the management processes of various resource flows of «open» development projects; consideration of the processes of phased emergence and completion, movement, ordering and transformation of project-flow processes; matrix analytics for the formation of stage-by-stage and logistical environments for functioning and eco-environments of interaction between stakeholders - performers and stakeholders - carriers of resource flows in the space for the implementation of organizational and technological stages of projects, etc. The main results of the study were as follows: the possibility of an eco-environmental approach to the stage-by-stage management of various resource flows of «open» development projects; new concepts of stakeholders - executors and stakeholders - carriers are introduced as step-by-step functioning and interacting infrastructure environments; formed quadratic and cubic matrix of structural.
