The city of Bergen has a goal of becoming fossil-free in 2030. How do we get there? Some weeks ago, local experts from different domains came together and developed a causal loop diagram (CLD). This will form the skeleton for the modelling hackathon.  @ LinkedIn ,  Twitter ,  YouTube      Video    D

The real nasty thing about this structure is that the two Balancing Loops form a single Reinforcing Loop which inhibits growth.

Leverage Point Modeling (LPM) is a demonstrated approach for improved planning and spending for Operations and Support (O&S) activities. LPM is a continuous-event simulation technique that uses the System Dynamics approach of model building. Dr. Nathaniel Mass championed the potential of LPM, and adapted it for the Department of Defense (DoD) as a tool for jumping to a higher performance curve as a means of offsetting higher costs and declining budgets. The purpose of LPM is to test policies and investments that improve mission capability for a given level of investment or funding. It is particularly used to evaluate investments in component reliability and parts availability. Ref: http://bit.ly/aT44kB

There is much we can learn from the development of qualitative relationships models though once we begin to ask questions like how long, how much, when, etc., a qualitative most is not likely to be of much use. The following video demonstrates how, in a very simple goal-seeking structure with delay, depending on the delay, it can be almost impossible to intuit the implications of the interactions with any level of accuracy. The difficulty arises essentially from operating with outdated data. See also Archetypes.

OK, we have a problem. Yet, do we really know what the problem is? More often than not we look at the symptoms, consider them the problem and attempt to fix them. This actually dooms us to failure because they're only symptoms.   Video    SystemsWiki's Musings
