In the first part of the series, we considered the Concept-of-Operations, identifying the system domain and its primary objectives. We also considered the objectives of a Bad Actor who desires to abuse the system. Finally, we brought requirements into the model. Now we will go ahead and start designing the system, following those requirements. We

Having established the system domain and high-level objectives of our Electronic Voting System (EVS) in Part 1, the typical next step in systems engineering is requirements process in which we generate the requirements that the system must meet. A common pattern here is that requirements are managed in a specialized requirements management tool like DOORS

Recently I took the opportunity of the INCOSE International Symposium being in Washington DC to consider how modern approaches to Systems Engineering might impact an issue with political and social implications, specifically electronic voting system (EVS) security. It’s impossible to open the newspaper or turn on the TV without hearing something about election security issues.

Introduction In this series we have sought to demonstrate how Model-Based Systems Engineering (MBSE) could be applied to designing a railgun (Figure 1) which uses electromagnetic fields to accelerate and launch a projectile at very high velocities. In previous sections, we have described the fundamental physics, then applied the SysML modeling language and Intercax SysML-compatible

Introduction In this series, we have been developing a model for an electro-magnetic railgun (Figure 1). To this point, it has primarily been a descriptive model, capturing concept of operation, requirements, architecture and mechanical and electrical design. However, a key benefit of Model-Based Systems Engineering (MBSE) is that it can couple the descriptive models with

Introduction Railguns (Figure 1) are an interesting combination of electrical and mechanical design, testing the capabilities of Model-Based Systems Engineering (MBSE) to connect these domains. In Part 2 of this blog series, we described the composition of the system and the requirements governing it. In this section, we will create a generalized electrical schematic using
