Introduction

The study of big data is constantly expanding, and the main characteristics of big data are now subdivided into the “5V” concept, consisting of Volume, Velocity, Variety, Veracity, and Value (Emrouznejad 2016, Kitchin and McArdle 2016, Onay and Oztiirk 2018). As big data have experienced a transition from being an emerging topic to a growing research field, it has become essential to classify the different types of research and examine the general trends of this research area. Continuous efforts to create more sophisticated technology to gather data at different steps of the supply chain have led to a new era of supply chain analytics (Ulkii and Engau 2020). Using big data, developers such as Amazon, United Parcel Service (UPS), and Wal-Mart, are gaining unprecedented mastery over their supply chains. They are achieving greater oversight into inventory levels, order fulfillment rates, and material and product delivery using predictive data analytics to adjust supply with demand, leveraging new' planning strengths to optimize their sales channel strategies, optimizing supply chain strategy and competitive priorities, and even launching powerful new' ventures. The concurrence of events, such as grow'th in approval of supply chain technologies, data inundation, and a shift in management focus from heuristics to data-driven decision-making, has collectively resulted in the advent of the big data era. In spite of these opportunities, many supply chain operations are restricted or obtain no value from big data. Using these methods, we can overcome widespread difficulties by making the most of big data in the supply chain and increasing cost efficiencies from the already produced data. This process should allow recognition of potential research fields for future research.

In this chapter, a short analysis on big data analytics in supply chain management was done. This chapter presents a general analysis of the current developments in the growing field of big data analytics in supply chain management by using scientomet- rics and charts.

Analysis

Data Collection

For this scientific analysis, a scientometric mapping technique was used to discover the most common keywords used among published articles. First, we searched for the topics “big data” and “supply chain management” in the SCOPUS database between 2000 and present. More than 700 research articles were found (as of June 14, 2020). Figure 1.1 show's the distribution of papers from 2000 omvard.

Most of the analysis in this chapter was done with VOSviewer, which is know'n as a powerful software for scientometric analysis (Van Eck and Waltman 2010, 2011, 2013), and some researchers have used VOSviewer for their analysis (Emrouznejad and Marra 2016, Rahimi et al. 2017, Gandomi et al. 2020).

Introduction

Big data more often than not incorporates data and information with sizes over and above the potential of software tools that are regularly used to apprehend, select, organise, and process information enclosed with the bounds of an adequate elapsed clock [1]. Although it emphasises on unstructured data, its philosophy embraces structured and semi-structured data too. Structured data embodies data - often numeric in nature, that is already organised by the institution through data sets and spread sheets. Unstructured data are cluttered and do not belong to any preordained model. It involves data obtained from social media sources, which assist institutions to muster information on customer requirements. Nevertheless, it is not the amount of data that is vital. The main concern, however, is how that data are utilised in the organisations [2]. It is possible to examine the big data for perceptions that make way

for enhanced judgements and tactical organisations advancements [3]. Figure 2.1 portrays the all-inclusive technique involved in deducing information from big data. Big data process can be further divided into management and analytics. The methodologies involved in acquiring and storing data and information are associated with data management. It is also involved in preparing and retrieving data for further analysis. Data analytics represents the approaches required to perform analysis and gather information intelligence [4].

Henceforward, big data define the large volume of data, necessitates a group of methodologies, procedures, and automation along with innovative structures of integration to expose perceptions obtained from data and information which are known to be varied, intricate, and are of enormous in measure [5].

The definition of big data can be summarised as the three V’s [6] mentioned below:

  • • Volume: It is the quantum of produced and stocked data. The magnitude of information gathered decides the usefulness, significance, and prospect insight. Organisations gather information from a humongous mixture of sources, together with IoT devices, business transactions, equipment from industries, audios, videos, social media, and many more [6]. The pressure on the storage load has been relieved in present scenarios by using platforms like data lakes and Hadoop.
  • • Velocity: Data gush into businesses at a strikingly exceptional momentum due to the broadening of IoT and require to be grasped in an appropriate method. Popular RFID labels, automated meters, detectors and sensors, propel prerequisites to deal with the inundations of such data and information instantaneously.
  • • Variety: Information is known to be in a heterogeneous format. Structured data - obtained from traditional databases in numeric form to unstructured data - word presentations and documents, emails, visuals, sounds [7].

Supply Chain: Big data analytics models to unveil intricate details in the voluminous data and acquire valuable insights from it. And, supply chain is an exceptionally powerful contributor to big data [8]. Supply chain is a complex web of all the people, agencies, assets, activities, and technologies demanded in the development to the purchase of a product, including all the functions that emerge with receiving an order to fulfilling the end user’s request, through developing a product, operations and marketing, distribution networks, business and finance, and end-user or customer service [9].

The entities connected in the supply chain include manufacturers, vendors, repositories or warehouses, travel agencies for transportation, distribution centres, and retail agents. Activities of the supply chain comprise converting raw products and apparatuses into a fully furnished and completed product that is produced to the users [10].

The inputs gathered by Supply Chain contain data from important entities like manufacturing and production, development, logistics, and retail [11]. The application of Big Data Analytics on a stream of such abundant data in the supply chain can nurture a dynamic phenomenon of making decisions to predict prospects and perils.

Introduction to Supply Chain Analytics Technology

It exhibits the potentiality to take information-based judgements, with the grounds of the outline and overview obtained of the vast information, with the help of visual tools such as charts, diagrams, graphs, tables, and more. Supply chains produce enormous quantities of information. It provides assistance by discovering patterns and providing insights. Supply Chain Analytics enhances the process of making decisions for all tasks by making use of the data and quantitative and analytical methods [12].

Supply Chain Analytics lays down the foundation for businesses to accomplish the desired challenging growth, improve their profits, and increase their market shares by exploiting the derived insights from the gathered data.

Necessity for Supply Chain Analytics for Big Data

Businesses, Organisations, Companies dealing with enormous amounts of data require Supply Chain Analytics to assist them in making faster, smarter, and more efficient decisions [13]. With Supply Chain Analytics, organisations can improve their forecasting, identify their drawbacks and inefficiencies, react better to user’s requirements and needs, drive innovation, and follow innovative ideas.

Supply Chain Analytics is required to:

  • • execute the precise solutions to specifically analyse, predict, and interpret data big
  • • identify the risk indicators
  • • responding in a punctual manner to the insights obtained

It is also known to be the fundamental foundation for involving cognitive technologies like artificial intelligence (AI). Cognitive technologies like humans perform understanding, reasoning, learning, and interacting but at aggressive speed and capacity. Such advancement with the supply chain has turned over a new' leaf for the optimisation of big data [14].
