RAM Products with Ramentor AMS

ELMAS is the basis of the whole RAM product/expert tool family. All analysis is based on the logical model created in ELMAS. In addition to the analysis module integrated in ELMAS, there are other advanced expert tools for specific purposes. These tools are fully compatible with ELMAS and work seamlessly together forming an extremely powerful entity. The analytical power of these tools derives from an advanced stochastic simulation engine.

ELMAS

ELMAS is a software system for modeling and analyzing event logic using a tree model. The model is suitable for handling very large and complex systems both visually and analytically. Using ELMAS also improves documentation of the modeled system. For example: A tree node representing a physical component or subsystem could contain images describing how to detect a typical failure situation. There could also be hyperlinks from the node to maintenance documents for the specific component or subsystem.

Analyzing the model is primarily done by stochastically simulating the system based on the logical model and failure- and repair- data for the components involved. Basically this means running the system virtually for say 100 years. Analyzing the results reveals very valuable information on the system behavior and how to most cost-effectively improve the systems reliability and availability during its whole life cycle.

ELMAS network is designed for team work. It supports work sharing by enabling references from one project to another. Typically there is a master project that references several, possibly nested, subprojects. Each of such subprojects may be developed and maintained separately and by different responsible personnel or subcontractor. All updates are immediately reflected to referencing projects also. Access rights for projects are granted for groups of users. A user may naturally belong to several groups. Access levels include read, write and reference. ELMAS network includes version handling.

RAMalloc

RAMalloc enables allocation of reliability requirements for components of a system. It is a valuable tool for selecting an optimal solution to meet overall reliability requirements in most cost-effective way. It gives a reasonable justification to demand subcontractors to meet the analytically achieved requirements. RAMoptim is the tool for finding out whether such a subsystem will meet those requirements as such, or if further development is necessary.

RAMoptim

RAMoptim is a tool for optimizing a systems reliability, availability and maintainability. The tool produces reliable predictions of how the system will behave during its whole life cycle. For example the following information is achieved:

• System reliability
• Need of repair resources
• Costs caused by failures and maintenance actions
• Components whose failure tendency is high enough to make them in practice (according to the modeled logic) the most usual root causes for the failure of the entire system.

StockOptim

StockOptim focuses on optimizing spare part stocks. It enables minimizing costs of running a stock without disturbing the supported process. This tool enables calculating the most important availability- and cost related factors of running a warehouse. For example the following factors are included.

• Minimum and maximum points
• Information about periods lacking the requested items
• Demand of items
• Circulation periods
• Costs related to storage, orders and transportation
• Supplier logistical comparisons
• Alternative warehouse strategies (by machine, mill, local, country, central, supplier etc.)
