Description: The paper formulates requirements for the architecture and functional characteristics of information systems (subsystems)of production logistics based by multisets model of material flow. Algorithms implementing operations of multisets model of material flow are proposed. The proposed data model is sufficient for the implementation of information systems based on multisets model of material flow. The proposed solutions are not limited to a particular branch of production and are common to production logistics. In the article are used the universal modeling language UML and techniques software engineering.
