Regularity Analysis

Regularity is a critical issue for all process oriented industries. Problems along the value chain will inevitably jeopardise overall efficiency and deliverability thus accumulating a loss.

Quantitative analysis of the production availability or deliverability of a production and distribution system is often denoted RAM, referring to the three essential elements Reliability, Availability and Maintainability.

In a RAM analysis, simulations are used to calculate reliability, availability and maintainability figures for a technical system. The most important feature of a RAM analysis is the input (capabilities, failure rates, consequences of failures, spares, mobilisation times, supplies of utilities and resources, system operating roules etc.). These measures and their coherence are used to estimate by other:

• Productiveness
• Spare part consumption
• Repair resource requirements
• Repair strategies.

For RAM analyses Scandpower use the software tool MIRIAM Regina. This is a powerful and flexible reliability and availability analysis program to evaluate the operational performance of a flow network, e.g. a process plant, in terms of equipment availability, production capability and maintenance resource requirements. The program models the stochastic behaviour of a system over time.

The system to be modelled is defined as a simplified network of elements. The stochastic behaviour of the system over time is represented using next event simulation techniques (Monte Carlo Simulation).
