Abstract
Due to the enhancements of Internet of Things (IoT) and sensors deployments, the production of big data in Industrial Internet of Things (IIoT) is increased. The accessing and processing of big data become a challenging issue due to the limited storage space, computational time, networking, and IoT devices end. IoT and big data are well thought-out to be the key concepts when describing new information architecture projects. The techniques, tools, and methods that help to provide better solutions for IoT and big data can have an important role to play in the architecture of business. Different approaches are being practiced in the literature for evaluating the role of big data in IIoT. These techniques are not handling the situations when complexity of dependency arises among parameters of the alternatives. The proposed research uses the approach of Analytic Network Process (ANP) for evaluating the role of big data in IIoT. The results show that the proposed research works well for evaluating the role of big data in IIoT.
1. Introduction
The developments in the field of data processing, Internet, and electronic communications have enabled the world to easy access to different physical devices. The whole world is covered with different devices embedded with the actuators and sensors. Huge bulk of data is produced from the communication of these heterogeneous devices which need to be researched for mining useful insights. These useful information and insights will play an important role in decision-making and optimum management or services and resources.
The integration of emerging trends, technologies, and applications of IoT in the industrial environment is leading toward the expansion and developments of IIoT. The IIoT is collection of smart devices and objects which sense, collect, process, and communicate real-time occurrences in the industrial setup. IIoT aims to achieve high efficiency of operation to manage industrial assets and increase the productivity of industry with the support of product customization. In the last few years, special attentions were given to the applications of IoT with emerging into the industry. Several IoT devices are brought to facilitate the human life. The applications of IoT technologies in industry of automation have been expended to the IIoT which supports Cyber Physic System in which human and machine interact [1]. Internet of Things has several applications in the daily life and has made life very easy. From industry to education, healthcare, and to other place, the IoT is mostly used. Internet of Medical Things is the advanced version of IoT which has a key role in healthcare. In healthcare, the devices are sometimes connected through heterogeneous environment with the support of different IoT devices.
IIoT takes help from the communication of IoT in the applications of business which mostly focus on the interoperability among machines. As the daily life objects and things connected to the Internet are increasing with the passage of time, which made the IoT be dynamic network of networks, more challenges such as dynamicity, heterogeneity, volume, and velocity of data makes the services of IoT inconsistent, incomplete, inaccurate, and incorrect results which resultant can make complexity for the applications of IIoT such as healthcare, wearable, smart transportation, and industry [2].
The contribution of the proposed research is to use the approach of Analytic Network Process for evaluating the role of big data in IIoT. The process of pairwise comparison was carried out for the criteria and available alternatives. The results show that the proposed research works well for evaluating the role of big data in IIoT.
The organization of the paper is as follows. Section 2 presents the related work to the role of big data in IIoT. Section 3 shows the research method of the proposed research. The results and discussions are shown in Section 4. The paper is concluded in Section 5.

3. Research Method
Various taxonomies such as analytics tools, data sources, analytics techniques, industrial analytics applications, and requirements are used in the literature for analysing the data. Figure 1 shows the 5 Vs of big data.
Figure 2 shows the generic IIoT.
The proposed method has used the Analytic Network Process for the evaluation of role of big data in IIoT. The ANP has several applications in different areas [22–25]. The ANP approach was selected for evaluating the role of IIoT due to the reasons as this method works very well in situation, where complexity of dependencies exists among criteria and alternatives. The ANP method consists of three parts: (a) the goal, (b) criteria, and (c) alternatives. Five criteria along with subcriteria and three conditions were available as alternatives. The details regarding the ANP can be found in saaty (1996), while the following are the main steps of the ANP:(a)Division of problem into subcriteria(b)Quantitative scale of measure between 1 and 9(c)Pairwise comparison for criteria and alternatives to achieve goal(d)Eigenvalue and the related Eigenvector of the comparison matrix(e)The consistency of matrix is measured The “Consistency Index (CI)” and “Consistency Random (CR)” of pairwise comparison matrix are computed by equations (1) and (2): Random consistency (RI) table is given by satty and is shown in Table 1 [26].(f)Construction of weighted matrix(g)Conversion of weighted super matrix into limit matrix(h)Decision of the alternatives

The process of pairwise comparisons of the proposed study was carried out in order to decide about available alternatives. The experts from the industry involved to check the contents against the available alternatives and relevant score should be given. Table 2 shows the pairwise comparison with respect to condition 1 for the available criteria.
Table 3 shows the pairwise comparison with respect to condition 2 for the available criteria.
Table 4 shows the pairwise comparison with respect to condition 3 for the available criteria.
Table 5 shows the pairwise comparison with respect to criteria (volume) for the available alternatives (conditions).
Table 6 shows the pairwise comparison with respect to criteria (variety) for the available alternatives (conditions).
Table 7 shows the pairwise comparison with respect to criteria (value) for the available alternatives (conditions).
Table 8 shows the pairwise comparison with respect to criteria (veracity) for the available alternatives (conditions).
Table 9 shows the pairwise comparison with respect to criteria (velocity) for the available alternatives (conditions).
After pairwise comparisons, the E.V values of all the tables were merged into the weighted matrix. Table 10 shows the weighted matrix.
The weighted matrix (Table 10) was converted into the limit matrix in order to get the most appropriate condition in the available alternatives. Table 11 shows the limit matrix of the proposed study.
From limit matrix (Table 11), it is concluded that condition 1 is the best option among the available alternatives followed by condition 2, and then condition 3. Figure 4 shows the decision of the available alternatives with their rank.
