 students welcome to module 195 in this module we are going to cover a very very interesting concept which definitely you have not heard about it before we are going to cover industry 4.0 industry 4.0 is basically fourth industrial revolution that is called industry 4.0 and we will touch on this a little bit so that you can see the importance of this in the modern world especially manufacturing, its planning, its management in its perspective we will see it as I have told you that this is one of the most modern concepts in manufacturing again its foundation that is based on internet and telecom the concept of your 4.0 and 5.0 or definitely you will be aware of these concepts you must have heard about them so basically this is the dependency on this and the second angle of this is called one more concept you will hear is internet of things i.o.t and industry 4.0 this is industrial internet of things i.i.o.t as i have told you this is one of the most modern concepts this basically happens if you just imagine the manufacturing industry which you are aware of just think about it if there is a plant which is manufacturing cars or motorcycles just imagine about that to manage it there is a whole team there is a manufacturing process from one station to the other and in the end the car is ready to go out imagine that the company's management they are sitting in some other part of the world that is a manufacturing plant of Japanese Toyota which is in South Africa and its owner wants to see it in Japan so what people... I am not saying that you put the camera on it you create a digital image of the factory and the data on it is real time whatever happens at some time at some work station or the pad you call it all the robotics are done everything is producing data all the robotics are done apart from the data produced all the operators are done all the data are done in real time your physical factory and the twin of the factory you can say that the twin of the factory everything is seen there real time or near real time this is basically the concept of Industry 4.0 in which everything is fully connected that your customer basically the stakeholders company's management company's employees company's customer your partners your different providers your vendors everyone is connected to the same system this is basically the concept of Industry 4.0 in this we talked about different technologies if you move away from the automobile there is another industry it is called Surface Mount Technologies for example if you open your mobile phone or open your laptop you will see a motherboard it is called PCP Printed Circuit Board on it there are ICs and transistors and such things there is your CPU your RAM all these things are planted on it this work is one there is a production line on it there is one machine it takes up some things if the robot is planted there are different ICs on it like for example the RAM your CPU your graphic card the robot is planted on it it plays on it it is automatically sold like we understand the soldering process everything happens automatically after that it goes from the conveyor and at the end there is a machine it is called A.O.I. Automatic Optical Inspection the optical automatic then it is measured that the ICs on it sit properly or not the size of the tank the size of the soldered and then there is a visual testing and the right pieces on one side and the quality control the A.O.I. keep it on the other side now you can see that this whole process is fully automated and there is no human intervention involved in it now this system you can call as one example of industry 4.0 the different machines used in it there is a stacking machine there is a pick and place like the A.O.I. example there are different manufacturers like Japan, Europe so every machine produces that data when you create a digital image of this assembly line to create a digital twin it means that you have to extract that data then you have to load the digital image so that the simulation of that data you can see that on the physical machine or the monitor on the physical machine so this whole process this is part of the industry 4.0 and there is a big part again, data extraction every machine which I have given you a practical example one machine produces that data in one format another machine produces that data in another format third machine produces that data in a third format and the types of data are different formats are also different the role here you have learnt python you have learnt the ETL technique you have learnt how to store the data you have learnt data lake practically you will understand you will experience that that you have to collect the data of every format you have to convert it in a human readable format then you have to take it to the database then you have to perform different analytics this is the paradigm shift there is a whole shift in manufacturing which is conventional manufacturing this was the third generation in manufacturing in 4th generation there is a very huge difference in this how you can control your things from one place in every industry we have talked about our data sources again, I just reiterate that we are talking only here about data because you are inshallah going to be a data scientist and your professional life that will be again data right this industry 4th generation the different equipment the different production machines even if you take any industry nowadays almost every industry you take your textile industry you take your car manufacturing you take your automotive you take the electronics industry the different equipment the machinery is automated and even sometimes they have their own built-in PCs they produce their own database or they are IoT based so they generate the data and you have to understand that as a computer scientist as a data scientist your first and foremost understanding about your organization is that we are talking from the very beginning of data sources IoT data sources are your production lines production lines can also be your ERP which is called MRP material resource planning for manufacturing you need raw material the purchase order of your entire procurement system you need to understand the customer relationship management system you need to understand the different system the plant maintenance is very critical the plant maintenance has its own modules the system is available you will plan the equipment the machinery when it will come down time when it will be closed production planning is aligned everything is aligned if you allow me to use the word orchestrated again everything is orchestrated in a big manufacturing company industry 3 or industry 4-0 is working on the level everything is integrated with each other and if you see 10, 20, 30, 40, 50 different software applications which can be integrated with each other the use case there are many possibilities the biggest use case the equipment the machinery the calibration the machine is producing data there is a possibility that you can create something the quality assurance I gave you this SMT production I gave you the example of the line the AOI in the end the quality control in every process if you put 100 pieces after every stage everything is being checked which is called quality assurance every step you check the quality end of the day end of the shift end of the one item if you put one lot in that production ratio good, bad, bad then there is another thing the different errors and defects the data the defects are coming how many are critical how many can you ignore so this is a great use case or in manufacturing the quality assurance if you keep it automatic anyway this is the work but now with in industry 4.0 your quality assurance that is happening automatically and it is being reported and the most interesting thing is that you can define the threshold that if my defective pieces their percentage or ratio you say 95% then for example 94% 93% then the production will stop and the company will manufacture defective pieces so this is one of the use case for the quality assurance and calibration of the equipment thank you
