From the practical view, I guess, is buy a new one. But it can be a great investment. I think is better to analise your specific case. It's difficult to say a correct answer to you without more details.
I believe the concept of engineering is to use available resources to get the maximum output or design with the available resources in such a way,to make its functionality dynamic and to suit needs.
I agree with Divya respect to optimize the integrated system than instead to buy a new one due to the great investment required besides the time involved in all the process
What do you have to say as regards its salvage value@julio,juan and divya
Like Edson mentioned above, It would be best to analyze the system's current state and weigh all possibilities. If the system's salvage value is much much less than a new system and its performance is bad, than buying a new system is better than upgrading the old system that would probably cost more effort and you might not get good returns. But If the salvage value is even close to a new system, then just consider upgrading the old with better engineering, so over the long run the salvage value doesn't depreciate to hit rock bottom.
hi, let me try. couple of factors to be considered. first and foremost, is there new expectation on the system? is it not catering as per the latest expectation? if that is the case, what is the percentage deviation from the expected outcome? Is it causing serious losses or is it negligible. In this context, it is about the capability of the system. You must have a certain percentage of tolerance in order to consider a new system as a small percent may be negligible. If you are unsure or you think the system is not catering as per the expectation, you may want to work out a Return on Investment (ROI) analysis together with the cost of maintaining the system. You may want to come up with a 5 year analysis or depending on the timeline that you are familiar with and work out a ROI for both the old and the new system. Consider the same input variables for both systems. Work it out to compare both. Bottom line, if you are seeking for a new system, there must be a reason to acquire it.
Thanks krishnan, edson, divya, Julio and Juan. You guys did a proper justice to my question.
Once again I say Thank you.
