 BlockSim
7 provides a sophisticated graphical interface that allows
you to model the simplest or most complex systems using Reliability
Block Diagrams (RBDs) or Fault Trees -- or a combination of both
approaches! The software then algebraically computes system reliability
results and optimum reliability allocations based on the exact system
reliability function. BlockSim also provides a sophisticated discrete
event simulation engine for reliability, maintainability, availability,
throughput, life cycle cost summaries and related analyses.
Flexible
Reliability Block Diagram (RBD) Creation
BlockSim's interface for Reliability
Block Diagram (RBD) creation is the most intuitive, flexible and
polished in the industry.
- Simple drag-and-drop techniques
allow you to build RBDs for the simplest to the most complex
systems. Configuration options include Series, Parallel, and
k-out-of-n (and in various complex combinations) plus...
- Load Sharing Blocks: In
a load sharing configuration, each block supports a percentage
of the total load.
- Standby Blocks: In a
standby configuration, standby blocks are available to become
active under specified circumstances.
- Mirrored and Multi Blocks:
Provide increased versatility with the ability to simulate
bi-directional paths, save time/space when entering multiple
identical blocks, and more...
- Unlimited subdiagram capability to
link diagrams as components in other diagrams.
- Customizable graphical display
with the ability to export diagram graphics.
- Pre-defined templates and
import/export to save time and ensure consistency, ability to
de-activate individual blocks for "what-if" analyses, file
attachments, and more...
Integrated
Fault Tree Analysis Features
Now integrated with the
standard package in Version 7!
BlockSim's fault tree analysis
interface supports all of the traditional FTA gates and event symbols
that are applicable to system reliability and related analyses
(including AND, OR, Voting OR, Inhibit, Priority AND and Sequence
Enforcing gates along with Basic, Undeveloped, Trigger, Resultant and
Conditional events). In addition, BlockSim allows you to expand the
modeling capabilities through the introduction of new logic gates to
represent Load Sharing and Standby Redundancy
configurations.
Your BlockSim projects can contain both fault trees and
reliability block diagrams, together in the same analysis environment.
You can even integrate your fault trees and RBDs by linking a fault tree
as a subdiagram to an RBD or vice versa; copying events from a fault
tree diagram and pasting them as blocks in an RBD; and automatically
converting any fault tree diagram to a reliability block diagram.
Exact
Reliability Results/Plots and Optimum Reliability Allocation
Using an exclusive algorithm pioneered by ReliaSoft,
BlockSim algebraically computes the
exact system reliability function for even the most complex
systems. Calculated results include Reliability, Failure Rate, MTTF,
Warranty Time, B(X) Life, pdf plots, Reliability Importance
plots, and more...
Also exclusively in
BlockSim, you can enter cost and
achievable reliability improvement information to determine the most
cost-effective component reliability allocation strategy to meet a
system reliability goal.
Extensive Simulation
Options for Analysis of Repairable Systems
BlockSim's
simulation capability for maintainability and availability analysis of
repairable systems is more sophisticated and realistic than ever.
- Corrective Maintenance (CM), Preventive Maintenance (PM) and
Inspection
- Maintenance Duration and
Restoration Factors: Specify time-dependent distributions or
fixed durations for maintenance actions and whether the item
will be "as good as new" or less than 100% restored by the
maintenance.
Enhanced
in Version 7! Support for Kijima model Type 1 Restoration
Factors is now available.
- Maintenance Policies:
Describe the conditions under which maintenance will be
performed (e.g.
upon fixed interval, maintenance of another group item, etc.).
- Spare Parts Pools and
Maintenance Crews: Describe the conditions under which spare
parts can be obtained and crews are available to perform
maintenance, as well as the associated costs.
- Duty Cycles: Apply
a factor to define a duty cycle for a block that may experience
a different stress load than the other blocks in the diagram.
New in
Version 7!
- Phase Diagrams: Use BlockSim’s intuitive Phase Diagram
Sheets to model systems that go through different phases during the
course of their operation. For example, some aircraft components
(such as landing gear) operate only during the take-off and landing
phases of a mission and others (such as engines) experience a higher
failure rate during these phases due to higher stress. Only BlockSim
provides the ability to completely change the configuration and
component properties from one phase to another. The software also
introduces and fully supports the concept of Maintenance Phases,
which allow you
to model scenarios
in which a system goes into maintenance after completing a specific
sequence of phases or skips remaining phases and goes directly to
maintenance if a failure occurs.
New in Version 7!
- Comprehensive Results and
Plots:
Maintainability and availability results per system and/or per
block including: Uptime, Downtime, Mean Time to First Failure
(MTTFF), Mean Availabilities, Point Availabilities, Point
Reliabilities, Number of Failures, Number of PMs, Number of
Inspections, Plots of System Uptime/Downtime, Point Availability vs.
Time, Point Reliability vs. Time, and more.
Enhanced in Version
7!
System "point" results are now available.
The simulations also provide Life Cycle Cost summaries,
Throughput
estimations, Optimum PM time calculations, and many other results
necessary to make effective decisions about your systems.
