Do you trust me as a blogger and Responsible Social Media Participant? - Narayana Rao




Do you trust me as a blogger and Responsible Social Media  Participant?

Are references provided by me in my online articles/blog posts sufficient and reliable?
Are my opinions clearly identified from facts or opinions expressed by others in their print or online articles?

Your opinion and suggestions will help me to improve my writing practice and rectify the errors and mistakes being made by me.

This query is prompted by the article written by Mr. Anurag Mehrotra, President and MD, Ford India, in Brand Equity paper of 10 January 2018. He wrote "finding information that's objective and fact-based has never been more difficult." People don't know who to trust or in whom to place their hope.

I actively participate in Google+, FaceBook, Linkedin and Twitter and also in Whatsapp sharing my blog posts, current as well as old ones and YouTube videos. I spend considerable time in the activity as I feel, I am doing a significant activity that way as every day thousand +  read my blog articles. But it is important to know the suggestions of readers in a systematic invited way to improve my writing and communication.

Thank you for your suggestions.


I make a special request to you subscribe to my YouTube Video collection on clicking Subscribe Button on any YouTube video of mine on YouTube. I uploaded 83 videos so far.

Mining meets Industry 4.0
West Angelas is one of the mines where Mitsui’s joint venture partner Rio Tinto is road-testing the deployment of the latest information technologies to extract minerals with greater safety and diminished environmental impacts.

At Rio Tinto’s Pilbara Operations Center, located in Perth (around 1,500 kilometers from the Pilbara itself), over 400 operators use real-time analytics and collaboration tools to optimize operations across Rio Tinto’s 17 mines, 4 ports and 1,700 kilometers of railway. Further innovative efforts include autonomous drilling systems (successfully trialed in West Angelas in 2008); autonomous haulage trucks for moving ore (also first trialed in West Angelas in 2008); and fully automated heavy-haul, long-distance railway systems (a world first).

Industrial Engineering 4.0 - Making Connected Engineering Systems More Productive


Industrial Engineering 4.0  was proposed as a parallel development in Industrial Engineering to take care of productivity of  engineering (production) systems in the era of Industry 4.0 Technology Set by Prof. K.V.S.S. Narayana Rao (Professor, National Institute of Industrial Engineering). Subsequent to the development of the idea, the Google search revealed that the term was already coined and used in Germany in 2016. But the digital content available on the topic has not provided enough explanation of Industrial Engineering 4.0. A project was initiated by Prof. Rao to elaborate the subject content of Industrial Engineering 4.0. The prime objective of Industrial Engineering 4.0 is to make connected engineering systems more productive.

_________________________


Prime Objective of Industrial Engineering 4.0

Making Connected Engineering Systems More Productive



__________________________

You can see reference to Industrial Engineering 4.0 in the following announcement about a seminar on 28 November 2017 in Germany.

Lecture event of the Friends of Industry 4.0


On Tuesday, 28. November 2017, at 19:30 clock we would like to cordially invite you to a lecture by Prof. Dr.-Ing. Jürgen Köbler, Professor of Industrial Production Technology, Digital Factory, Production Organization and Production Planning at the Faculty of Business Administration and Industrial Engineering of the University of Applied Sciences Offenburg invite to the Aula of the Gewerbliche Schule Lahr.

Companies have to constantly increase their productivity due to high competitive pressure. One area that is constantly increasing is industrial engineering. Especially in the course of digitization and networking of corporate processes, the lecture sheds light on how Industry 4.0 affects industrial engineering. The approach is to design an Industrial Engineering 4.0 that combines the advances of Industry 4.0 and the digital factory. In detail, the visions and basic requirements of Industrie 4.0, the change to product-oriented production planning and the gradual networking in the company are presented. Furthermore, Prof. Köbler talks about model platforms of Industry 4.0, new ways of information-driven production and the transformation from a conventional to a digital production company.

We would be pleased to welcome you at the event as guests at the Gewerbliche Schule Lahr. Admission is free. A donation in favor of the school partnership with Alajuela / Costa Rica is requested. I would be very grateful if you would forward the invitation to other interested people.

Sincerely, Bernd Wiedmann
Principal of the GS Lahr and managing director of the association

Examples of High Productivity Equipment and Machines


CNC Lathe for High-Productivity Vertical Turning of Flange-Type Workpieces


Extreme rigidity, high rapid traverse speeds and short strokes, together with the integral coolant system, guarantee precision, high productivity levels and short idle times for the VSC 250 production machine.

Okuma’s new 2SP-2500H CNC lathe featuring smart machine productivity

24 October, 2017
Okuma has launched the 2SP-2500H two-spindle CNC lathe, with innovative front-facing twin spindles to provide much higher levels of productivity and far greater reliability, for auto parts and other mass production applications. The 2SP-2500H is an automation-ready machine that integrates two lathes into one unit with a standard loader that feeds blanks for continuous front and back work.
https://www.cnctimes.com/editorial/okumas-new-2sp-2500h-cnc-lathe-featuring-smart-machine-productivity


In industrial engineering, product productivity engineering has to develop as an area of practice. Industrial engineers focus on increasing the productivity of processes and in that process identify improvements in machines and equipment that increase the productivity of the process under evaluation. This knowledge can be used in the development and design stages of machines and equipment. Hence within the industrial engineering profession, product productivity engineers and process productivity engineers can interact and exchange ideas and take up new development and design projects to create machines and equipment that provide higher productivity.


More Examples of High Productivity Equipment and Machines


Innovative, High Productivity Fiber Laser Tube Cutting

TruLaser Tube 5000 fiber laser tube cutting machine from TRUMPF is the world’s first tube cutting machine with a solid-state laser to eliminate the need for a fully enclosed housing, making it quick and easy to load individual tubes and profiles or to remove finished parts while the machine is in operation.

High Productivity Machines - Marketing Advantage


High productivity machines have  marketing advantages. They are rationally desirable and hence demand exists for high productivity machines. There is also the communication advantage. You can advertise high productivity machines, get immediate sales and also create brand value. Your company will be associated with innovativeness and high productivity. Whenever, machines are being replaced buyers look at your catalogues and include your company in the product request notifications.
