Shapes Toolbar
The Shapes toolbar in the Repairable Systems Simulation platform contains the block shapes used to represent components in the System Diagram. Add block shapes to the System Diagram by clicking the icon for the block shape and dragging it onto the System Diagram. The Shapes toolbar includes the following block shape icons:
Basic
Adds a single block shape that represents a single component.
Series
Adds a series block shape that represents a group of identical components that are connected in series. All of the components must be functional for the block to remain functional.
Parallel
Adds a parallel block shape that represents a group of identical components that are connected in parallel. At least one of the components must be functional for the block to remain functional.
K out of N
Adds a k-out-of-n block shape that represents a group of n identical components that are connected in parallel. At least k of the n components must be functional for the block to remain functional.
Standby
Adds a standby block shape that represents a group of n identical components that are connected in parallel. Only k components are active, or performing work in the system. The remaining inactive components act as standby components that are activated when any of the k active components fail. The block must have at least k functional and activated components for the block to remain functional.
Stress Sharing
Adds a stress sharing block shape that represents n identical components that are connected in parallel. Components fail one at a time, and remaining components fail at a quicker rate. The block must have at least one functional component and the block must successfully reallocate stress across remaining components for the block to remain functional.
Knot
Adds a knot block shape that represents a combination of the block shapes that point to the knot. At least a specified number of the block shapes that point to the knot must be functional for the knot to remain functional.
