RamLog Capabilities

RamLog is a software product developed by R&M Technologies.  It provides a practical solution to complex reliability, maintainability and logistic engineering problems. Various companies have successfully implemented the software since 1992. RamLog has a logistic database, support simulation and a failure recording capability. 

Logistic Database Capability

The logistic database capability of RamLog is based on the data model and field formats of MIL-STD-1388-2B/DEF-STAN-0060. Emphasis was placed during the development on simplicity and ease of use. RamLog provides methods to assist the user to perform a practical and cost-effective logistic support analysis. The user can easily develop and identify tasks and support requirements. Support analysis include, FMECA (Failure Mode, Effects and Criticality Analysis), RCM (Reliability-Centred Maintenance) and a DTA (Detail Task Analysis). Embedded drawing capabilities, enable the development of technical documentation. The user-friendliness makes it possible to perform the analysis concurrent with the design and therefore creates the opportunity to influence the design.  The logistic database can be used as an integral part of the system design, or as a pre-requisite to effective support and maintenance management. The logistics information which consists of a system breakdown structure (functional/hardware), FMECA, RCM, DTA, Task Network Diagrams, Reliability Block Diagrams and Fault Tree Diagrams are also the data depository for the support simulation capability.

Support Simulation Capability

The support simulation capability enables the user to simulate and solve, reliability, availability, maintainability, support and life cycle cost problems.  It provides an extremely flexible and easy-to-use modelling interface and is based on an object-based Monte Carlo simulation engine. It extracts data from the Logistic Database and provides the user with the unique ability to perform a simulation from the logistic database. The user can simulate and optimise the proposed support and maintenance concepts using facility objects and a Deploy and Support Model maintenance plan objects.  An operational phase object and an Operational Model make it possible to graphically build and simulate the operational scenario of the system or plant. Users can create their own cost breakdown and develop a LCC Model (Life Cycle Cost). RBD (Reliability Block Diagram) and FTA (Fault Tree Analysis) objects provide the capability to simulate the reliability, maintainability and availability characteristics of the system or plant.

Failure Recording Capability

The Failure Recording Capability is a failure and repair data management capability.  It extracts data from the logistic database to generate job cards to collect failure and repair data.  The flexibility of RamLog makes it easy to change the required job card format and to customise the Failure Recording and Corrective Action System (FRACAS) to the specific requirements. The close loop control system provides the ability to track serial numbers in a multi-level maintenance support scenario.  It also provides built status configuration control during maintenance.
