 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 BlockSims 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.
