EVALUATION OF SUPPLY CHAIN COMPLEXITY AT MATERIAL FLOW LEVEL FOR A ROMANIAN COMPANY
The supply chains became more and more complex in last years. Each supply chain has different information and material flows. Complexity measure variation can be done at both information and material flow. This article presents an evaluation of material flow complexity dealing with the volume of production as variable, for the main product of a Romanian company from the point of view of sales (financial point of view). The actual level of production and the expected (scheduled) level of production are considered. Data collection took place in the weeks 3-17 from 2018 (January – April).
The model uses the Shannon information entropy improved with Isik’s deviation of the outcome from the expected outcome value of the state. The usage of the model with outcome deviation is recommended because each state has its own complexity level. The complexity for a state with greater distance to the under control situation and the same frequency must be done first.
