This paper deals with the construction of the “Current Reality Tree” (CRT) diagram, as one of the Theory of constraints methods, to show a system of supply chain model regarding theindustrial logistics. The purpose of designing the CRT diagram is to identify undesirable activities (entities) in regard to production processes which have an adverse impact onenterprise costs and the customer service level. In the CRT diagram, links are defined withrespect to effects of the production elements on inventory in certain manufacturing enterprise. The more processes are closed to logistics optimum, the smaller quantity of inventory is in theenterprise. It is caused especially due to the fact that inventory acts like compensator for thedeficient production and logistics processes organization and management. Effort to integrate the material flows in production, minimize the inventory and maximize the flexibility inmeeting customer requirements leads to application of the basic logistics pproaches.
