If you are a professional engineer and that too in mechanical or civil, then you would require the knowledge in a lot of industrial technologies. You will have to understand the process of industrial automation. You would have to go through the components of a production process and identify the process components that could be automated. Unless you do some research work in this genre, you will not master this area. You will have to maintain a balance between utilizing manpower and removing unwanted delay in any industry. This is in fact highly followed in fertilizer and other chemical industries. So these and other related industries look for people who have done solid research work in industrial technologies. This course will give you a proper guidance regarding the technologies that are in use and those that will be the upcoming trends. Therefore, you should pursue a PhD. in Industrial Technologies.
