Process-oriented approaches to the design and modeling of logistic chains

The analysis of approaches to the design of a logistic chain, and also the reference models realizing them is carried out. The requirements for the process of logistic chains modeling are defined. It’s noted that the feature of modeling is a need for singling out various hierarchical levels of a model: processes of a logistic chain, and also processes of the corporate systems of separate enterprises. The classification of reference models using this approach is presented. The universal process model that allows meeting the noted requirements is offered. The model of a stream business process considers the specific character of a logistic business process - existence of three interconnected streams: material, information and financial. The features of modeling of streams on the example of supply chains are considered. The process model of a logistic chain when the contours of the process coincide with the borders of a separate link of a chain is presented in the article. It’s noted that this model doesn't reflect the full interaction of streams within a logistic chain, in particular, doesn't consider the movement of returnable material flows. The example of a model that enables us to consider the detailed interaction of streams in a logistic chain, constructed with due regard to the movement of material and financial flows using IDEF0 methodology is given. The suggested model of stream business processes allows modeling logistic chains with a different level of specification and reflecting the variety of movement of all types of streams. The described approach can also be used for the improvement of methods for evaluation of the efficiency of logistic chains.
