Event Logic Modeling and Analysis Software


Ramentor – ELMAS

Event Logic Modeling and Analysis Software (ELMAS) has been developed for modeling, analysis and optimization of systems' dependability and costs during their whole life cycle. ELMAS can be used, for example, to compare design alternatives, to estimate the return of investment time, and to optimize maintenance of the system. With a user-friendly graphical user interface and efficient simulation algorithms ELMAS is a powerful tool for comprehensive risk assessment and uncertainty management.

Risk assessment and RAMS

ELMAS – Risk assessment and RAMS

RAMS - ELMAS
ELMAS is used for modeling and analysis of logical cause-consequence relations between events, also called as event logic. An event can mean any change of state of any item, for example a failure of a component. In addition to relations between events it is possible to model other event-related features, for example occurrence rate of a root cause and expenses. The created model can be used to expand common knowledge and to structure and document data. The model also works as the basis for stochastic simulation based analysis.

RAMS = Reliability, Availability, Maintainability, Safety

ELMAS
ELMAS software is applicable to the modeling of almost any possible object. Usually the interest is in the failures of some equipment, process or system, but ELMAS can be flexibly used to find out root causes, model cause-consequence relations and analyze total effects of other events also. ELMAS software offers three different modeling possibilities that can be combined and fine-tuned to enable the modeling of very complex event chains: Fault Tree Analysis (FTA), Cause-Consequence Analysis (CCA), Reliability Block Diagram (RBD)
Analyzing

Analyzing

Analyze
ELMAS software takes into account the whole system functionality, recognizes the most critical objects, estimates the risks and helps focusing the maintenance and design actions for the system improvement. Due to its visuality ELMAS is also an effective tool for cooperation between maintenance and operations personnel and supports e.g.:
  • RCM-based problem solving and maintenance development,
  • FMEA-based failure mode recognition and effect analysis,
  • LCC-based comprehensive life cycle cost management.

Analyzing function allows defining predictions for e.g. component failure tendencies, most significant failure causes and cost risks coming from these failure events. Result analyzing gives important information about the behavior of the whole system. The aim of the analysis is to locate the methods that can improve the reliability and availability of the overall process as cost-effectively as possible.

Optimizing

Optimize
The results from the analysis phase provide an overall view of the availability and costs of the system. Based on the results it is possible to find out the improvement potential of the system and to move on to the actions planning. The aim of the actions planning is usually to optimize dependability, safety or overall costs. ELMAS offers versatile methods for finding suitable and effective system improvement actions.
Reporting

Reporting

Reporting
The created model forms a comprehensive document of the failure behavior of the target system. This model gathers the available expert knowledge in a clear and structured form. After this the whole knowledge, or a desired part of it, can be forwarded to other parties for example by creating a HTML-report that can be opened with a common web browser.
  • ELMAS software offers various ways for creating reports:
  • HTML report: Active report of the model and the attached data opened with a web browser.
  • Excel report: Compact presentation of the model and the attached data. Works also as an interface when importing data from Excel to ELMAS.
  • Table summary: Internal table of ELMAS that is typically used for checking, inputting and copying input data.
  • FMEA table: Internal FMEA table of ELMAS that can also be exported to Excel.
  • Actions report: Table-based summary of the planned actions. Possibility also to export to Excel.

Optimizing stock levels and storage costs

ELMAS - StockOptim
Spare part storage sizing is a part of risk management that is closely connected to dependability concept through the supportability of the system equipment. Ramentor has developed StockOptim software, which goal is to minimize the costs coming from storing and at the same time making sure that the supportability of the critical equipment will stay on a adequate level. StockOptim enables refining the spare part consumption data that is obtained from ELMAS analyses.
