Many process plants have an outdated Distributed Control System (DCS) currently in place. As a DCS reaches the end of its useful life, migration to a new automation system is required, but before this can take place internal plant personnel must provide a financial justification, typically to their corporate offices. This justification must compare the cost of continued operation with the DCS to the costs and benefits of migration to a new automation system. Cost and benefits for each option consists of many factors that together comprise the Total Cost of Ownership (TCO). To perform the most accurate analysis, all of these factors must be identified and quantified. ROCKWELL-AUTOMATION-2012-Justification-for-Migration.pdf
