The CMMS is the repository for data that documents the maintenance program, availability of maintenance spare parts and work order history. The history maintained in the CMMS also supports root cause analysis, resulting in improved engineering and manufacturing solutions. Bottom line, the CMMS is the cornerstone of supporting current operations, trending failures and providing knowledge for improvements that impact the bottom line.
Materials and Spare Parts Management
After working in the CMMS/ EAM software world for almost 16 years, I recently switched to an engineering consulting firm focused on helping clients implement reliability best practices. I’ve developed a fresh perspective on what it takes to implement CMMS/ EAM software successfully.
When exploring CMMS automation opportunities in your facility, there are many factors to consider. These include cost versus benefit by automating, cash-flow impact, organizational readiness, ease of implementation, availability of resources, technological maturity and availability, as well as probability of success.
Why automate, why improve? They’re all about the same question, so after covering the more general area, we’ll zoom in on the specifics of PLCs. “Why improve?” Because your competitors are, and you will not be in competition with them very long, if you don’t. “More and better” are today’s bottom line. With the customers being better educated, and having better availability of the product they seek, you have no choice.
You need to read this article on maintenance management of PLCs. Why? Because the PLCs (Programmable Logic Controllers) are the brains of your operation. When the PLC is not functioning properly, lines shut down, plants shutdown, even city bridges and water stations could cease to operate. Thousands to millions could be lost by one little PLC in an electrical panel that you never even knew existed. But most importantly, damage to machine and personnel could result from improper maintenance management of your company’s PLCs.
One of the most pervasive trends in fluid handling today is that of miniaturization. The call for smaller and smaller flow control devices is evident across the industry. Regarding hydraulic and pneumatic components specifically, the extraordinary mass-to-power and mass-to-response features of such technologies are enabling miniaturization.1 But as hydraulic and pneumatic devices continue to go mini, the manufacturing process has become more finite and certain design vulnerabilities have become more pronounced.
It is not necessary to totally restructure maintenance practices. A plant can start small and expand the use of process floor information as needs dictate and budgets allow. The key is to begin building a database from the smart devices now in operation and expand the use of the available information as the number of such devices grows. A scalable and expandable platform can grow into a plantwide system that supports the reliability and maintainability of all field instrumentation.
Today’s new control systems are delivering higher productivity to meet ever-increasing expectations of equipment performance. These systems typically contain more electronics, much of it adopted from non-industrial applications, and almost all of it more sensitive to electrical disturbances than the equipment being replaced. The following discussion provides information needed to develop a strategy for protecting sensitive mission critical equipment from the effects of a poor industrial power environment.
From the very start, the implementation of a computerized maintenance management system (CMMS) is a long and arduous process. One of the largest concerns is how to effectively get the correct data into the system in the first place, and then, how to get useful information out. The better and more consistently recording of repair activities is done, the greater potential for yielding greater and more specific information about an operation.
