Rethinking inventory strategy — new system dynamics research challenges retail norms.

A recent study shows that introducing a competing product earlier during an existing product’s decline phase can lead to higher long-term revenue.

Key insights for retail leaders:
Inventory decisions must model real substitution behavior
Early introductions can phase out old products more profitably
Demand forecasting should include stockout effects
Safety stock planning and shorter review cycles reduce lost sales
Dynamic, not static, strategies win in FMCG and tech retail

This is a must-read for anyone managing product portfolios, especially in fast-moving markets where demand shifts fast and substitution patterns aren't predictable.

Maybe in my #systemdynamics bubble someone can answer this question regarding #elasticity in a continuous-time dynamical systems context (i.e., it is a factor scaling fractional rates)?

Why is this (very natural) momentum-related formulation not more widespread in models?

Jay Forrester (at 21:00) about #systemdynamics and why governments around the world are not able to stop #climatechange:

"a deep understanding of these issues would make a very major change in the world but that deep understanding [..] has to include a public understanding because you cannot expect these changes to come from the top of a corporation or the top of a government. People in [..] System Dynamics as well as other approaches to policy design are always talking about convincing decision makers. There are no such people [..] When it comes to the big issues if a policy in government or a corporation is going in this direction and that's a governmental policy and you'd like to push it a little bit one way or the other then you can persuade and you can have lobbyists and you can bribe a few people and you can push it a little bit but if the real goal is to reverse it totally there is no government that's capable doing that unless there is a public support and so [..] it has to come up from the Grassroots [..] to be able to deal with the big issues that put the long-term ahead of the short term which is one of the main things [we need to do]"

John Scales Avery (1933-2024) was an American theoretical chemist. In his book "Civilization's Crisis" he argues that civilization as a whole faces a set of linked challenges. #ClimateChange is caused by consumption of non-renewable #FossilFuels but it is just one aspect of a bigger crisis. Other aspects are #Deforestation, #OceanAcidification, #NuclearWaste and #pollution in general. #ResourceDepletion and #VanishingResources in combination with #OverPopulation will eventually lead to a #collapse of #civilization in this century according to #systemdynamics and classic #limitstogrowth models. The turning point is #PeakOil or the #HubbertPeak which we are reaching now.

Prof Steve Keen recommended this short climate film to the seminars. So glad he did - I echo his recommendation! Strong shared themes with the climate elements of his critique of mainstream econ, incl. feedback loops, tipping points, and complex systems. And yet, accessible! An important film.

This thread is getting a lot more attention that I thought so I'm gonna explain common questions for you to feel more connected with this journey.

Why am I going to Bergen?
I'm actually going back to school! Taking a master's degree there, at UiB, in #SystemDynamics. Hope to stay for around a year? Maybe 2 or do the 2nd year remotely

Because I modified a #SystemDynamics / #SystemsDynamics diagram from StochSD for my scicomm.xyz profile, I want to take this opportunity to talk about how thrilled I was to discover StochSD (https://stochsd.sourceforge.io/).

If you like systems dynamics and #OpenSource tools for science and science #education, it's a great one to be aware of.

#introduction

Hello everyone.

I'm a lecturer at Tufts University, teaching courses in GIS, Food Systems Modeling, and Agricultural and Environmental Modeling.

My past research has included various forms of computer #modeling, including #SystemDynamics, and #GIS. I'm a strong believer in #interdisciplinary research and #stakeholder engagement as tools for improving and democratizing science.

I also once spent a year hanging out with the #STS group at Harvard, which shaped my thinking too.

"Ecological collapse is likely to start sooner than previously believed, according to a new study that models how #TippingPoints can amplify and accelerate one another" #biodiversity #ClimateChange #SystemDynamics #WickedProblems

In "Leverage Points" Donella Meadows ranks the ways of driving change in a system, from least to most effective. "Power has less to do with pushing leverage points than it does with strategically, profoundly, madly letting go"

A Philosophical Look at #SystemDynamics

A 1977 Video of a Donella Meadows talk, asking the question:

How can we bring ourselves to be aware of the assumptions we make as systems thinkers?
