A system of interlocking blocks and rods or tubes for rapid assembly of component infrastructures, where one or more of those components have electronics, power or other instrumentalities built into the component during manufacture, such as by 3-D printing, and the components thereof and methods therefor. The rods or tubes, blocks (for interlocking the rods/tubes) and through-holes allow not only structural stability but interconnectivity of electricity, power or other functionalities. The methodology of the present invention provides a paradigm for modeling more costly and complicated systems. Also, product packaging for products made pursuant to the present invention is scaled so as to be usable in the application of the parts.

A system and method for providing a digital simulation of a technical installation, and a corresponding computer program product, wherein the digital simulation is dynamically generated such that the digital simulation is adapted to a specified training scenario. This is accomplished using a provided basic class, which implements, independently of devices, functions of elementary hardware components, and using a library of virtual devices, which deterministically simulate the topology and the functional behavior of corresponding real devices. The virtual devices have a hierarchically nested structure, such that a hierarchically higher device comprises at least one hierarchically lower device and/or at least one of the elementary hardware components.
