2 Literature Review
In section of the study, literature review is presented and following aspects are included in this section (a) Introduction to artificial intelligence and (b) Growth of application of artificial intelligence in manufacturing.
2.1 (a) Introduction to Artificial Intelligence
The concept of artificial intelligence is reflected in the 1950s with the introduction of perceptron which is a part of neural network which is developed to simulate a human neural system by applying the weighed sum as input.
Even though the concept of has the foundation with regard to human learning and cognitive artificial intelligence, there was a reduction in the interest in this technology and many studies indicated that more information is needed from the experts for application of this technology is real world challenges.
Later in the development of the technology and introduction of the deep learning along with the advancement in sensing and computational with the combination of machine learning and deep learning lead to more application in the real-life situations of the organization.
The upgraded artificial intelligence technology with machine learning and deep learning was able to provide meaning that can infer and describe the behaviour of the human. Further, the application of this technology gained popularity, where the productivity of the human is enhanced in the organization and added value to the work process of the employees.
Hence, the technology of artificial intelligence which is the branch of computer science has become the part of development of the human and organization. In the present context, this technology dominates in various organization and play an important role in the development of the organization.
However, the biggest challenges that revolves around this technology is that due to rapid advancement in this technology organization need to learn to handle change brought by this technology and take the advantage of this technology for growth and development of the organization.
2.2 (b) Application of Artificial Intelligence in Manufacturing
The manufacturing operations includes production of higher-quality products with lower cost of production and also to provide safe working ecosystem for the employees at the shop floor of the factory.
However, matching these operational demands of manufacturing process has been challenge due to changing demand pattern of the customers and higher level of competition in the market, hence application of technology is a befitting direction for managing these manufacturing challenges in the organization.
Technology of artificial intelligence provides a road-map for meeting these challenges, as artificial intelligence is grounded on the concept of root causes analysis and then classifying based on the multivariate and nonlinear patterns in operational. This technology is based on the concept of data, and hence, large data is developed and generated, which is can be applied in the tool of artificial intelligence.
In the context of manufacturing process data is generated for artificial intelligence in four areas, namely environmental data, process data, production operation data and measurement data. In the context of environmental data includes information related to humidity at the shop floor, level of noise, etc. while process data in the manufacturing includes machining and grinding coolant temperatures, power, and heat treat temperature/energy.
Data related to production includes timestamps or elapsed time of each part in each operation station, machine downtime, starvation/blockage, idle time, and shift scheduling. Measurement data in the manufacturing includes product diameter, form, and balance.
Hence, artificial intelligence with the application of big data has the capability to improve the manufacturing process and also to solve complex manufacturing process, which also improves the quality and process of the manufacturing. Therefore, application of artificial intelligence in manufacturing would support in the making smart factories.
3 Proposed Artificial Intelligence Potential in the Manufacturing

Table 1 shows the list of criteria and sub-criteria related to the study on application of artificial intelligence in the manufacturing.
4 Research Methodology
The planned approach, i.e., fuzzy AHP and TOPSIS grey, is useful to apprehend the application of artificial intelligence in manufacturing sector. The respondents designated for the study include 25 production managers and 15 factory managers. The research included 40 experts to allocate weights to various criteria and sub-criteria and score each sub-criterion. The profile of the respondents’ is indicated in Table 2.
The suggested criteria for understanding the application of artificial intelligence are analysed using the fuzzy. TOPSIS has been used to assess and highlight the significant factor to act as an opportunity for effective implementation of this technology in the manufacturing sector.

Stage 2: Define the fuzzy
Stage 4: Calculate minimum possibility degree using equation
for (i = 1,2,3,4,5,6,7,……….,k)
for (i = 1,2,3,4,5,6,7,……….,k)
Stage 5: Let's assume weight vector
Finally, the weight vector can be normalized using equation
where W represents a non-fuzzy number,

Stage 5:
Stage 6:
Stage 7: Rank the alternatives on the basis of Ci in stage 6.
6.1 Grey System Theory
Prof. Deng proposed the grey system theory on the basis grey set concept.
The theory uses a grey no. to minimize uncertainty in the data.
TFNs can be converted into grey numbers using a˜ = (a1, a2, a3), and b˜ = (b1, b2, b3) into grey numbers ⊗ a = [a1, a2], and ⊗ b = [b1, b2] using Euclidean distance between ⊗ a and ⊗ b as given in the equation below:
