Complex products such as aircraft, trains and ships are high-value, long-life assets that are typically managed as a fleet over a period of 20 to 30 years.
Managing technology upgrades (modifications/ engineering changes) can be challenging because of the complex relationships and interdependencies that exist between different systems components.
An additional factor relates to the phenomenon of design divergence that can be observed as a fleet of products age.
I'd be interested in the quality of software available to model the design information in this scenario.
I'm not sure whether you mean CAD data management or something like statistical software to track the impact of design changes.
At least in CAD programs like Siemens NX offer the ability to generate multiple version within one model. For instance the same housing that contains different versions of electronics. You have a drop-down menu where you can choose between the versions
Dear Morris,
Hello
The question which has been inquired by you is, in fact, an important and also interesting question in field of “Design for Changeability” in discipline of systems engineering.
Dear , it is important to note that your concerned question actually encompasses a lot of sub-questions including design for “Adaptability”, “flexibility”, “reconfigurability”, “reliability/robustness”, and so forth. In addition, “propagation of change into the system due to change of one or more component(s) of the system under study. Moreover, in this regard, quantitative measurement of change in the system is another interesting and relevant issue.
As a useful suggestion to address and deal with the above challenges in system design, you could have a comprehensive study in both Axiomatic Design (AD) theory (especially, the information axiom of this theory to compute information content of a design to satisfy the system requirements) and “Design Structure Matrix (DSM) (especially, for the aim of studying the role of dependencies and/or interaction between any interest pair of system elements).
I think that the article attached to this reply could be a useful step to begin.
Hope the above helps!
Good luck!
Ali
Dear Morris
I would like to also add that all software for Design Structure Matrix (DSM) methodology (you could easily find all available software for this methodology by searching for that in internet) could be helpfully assist you.
As a final point to your question, in my view, you are in need of organizing your approach to deal with your concerended problem more than a software. In other words, it may be possible to employ a number of software packages to resolve all constituents forming your problem.
Sincerely,
Ali
