As the Software Model Custodian for PSOM (and the author of one of the above) I can assure you that PSOM is not a “black-box”.
All work on PSOM from it’s initial philosophy, through to its assumptions, conceptsa equations and V&V (verification and validity) tests have been documented and are freely available to current or prospective users.
Our website (https://psom.dstl.gov.uk/tiki/tiki-index.php) serves as an easy repository for this information. Though for obvious IPR reasons access to the website is restricted to those who have signed a Memorandum of Understanding (MoU) with us.
To be clear – there are no costs for accessing the server, downloading the documents, or downloading and using the model. Indeed as a trading fund of the UK Ministry of Defence we are not allowed to make profit.
When I went to a MORS workshop on irregular warfare at the end of 2007, Howard Body was demonstrating PSOM at one of the working groups. I was preoccupied with my own bits (the Algernon exercise, and presenting to another working group), but what I saw of it made me think it was quite “black-boxy”; it was difficult to tell what kind of assumptions were driving the model, how processes were calculated and so on. Four years later and they’re still using it, so perhaps that’s been addressed. Or not.
