ABSTRACT

One of the options for a more flexible approach to analyzing the reliability of supply chains is the principal component analysis (PCA). With a large number of variables describing supply chain, it is a difficult task to analyze the structure of variables in two-dimensional space. Within the analysis of the variables dependencies PCA allows to go from multidimensional space to low-dimensional space, leaving the most informative data in the array for analysis. Based on the generated data set, this paper demonstrates a possibility of applying PCA to supply chain reliability analysis. The generated data set includes observations of 50 supply chains described by five variables. Based on the array, maximizing the linear combination of parameters for each observation, we determined load coefficients and estimates of each of the main components. The calculation of these coefficients made it possible to move from multidimensional space to a two-dimensional one. The two-dimensional representation of all the data whose axes are the first two main components, explaining 84% of the variance, allows to see the structure of all supply chains, to identify outsiders and leaders in this set.

ABSTRACT

This article examines main influence of the Fourth industrial revolution announced in 2011 and of a lot of new technologies penetrating everyday life on existing processes in supply chain management and on its future development. The article reviews components of intelligent supply chains which are divided into two unequal groups: revolutionary and evolutionary technologies. The former ones are Internet of things, machine learning, 3d printing, blockchain, artificial intelligence and bots -all of which radically change the logic of supply chain work. The second group – evolutionary technologies – is more about successfully developing graphic technologies and functional organization of a workplace. The article mainly focuses on the first group. As a result, the article concludes that all these technologies closely intersect, which forms additional synergic effect of their contact; and that functions and responsibilities of an expert of supply chain management in a company should be thoroughly revised.
