Brian Greenberg :verified:<p>📊 Rethinking inventory strategy — new system dynamics research challenges retail norms.</p><p>A recent study shows that introducing a competing product earlier during an existing product’s decline phase can lead to higher long-term revenue. 🤯</p><p>Key insights for retail leaders:<br> 🛒 Inventory decisions must model real substitution behavior<br> 🔁 Early introductions can phase out old products more profitably<br> 🧮 Demand forecasting should include stockout effects<br> 📦 Safety stock planning and shorter review cycles reduce lost sales<br> 🧠 Dynamic, not static, strategies win in FMCG and tech retail</p><p>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.</p><p><a href="https://infosec.exchange/tags/SystemDynamics" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>SystemDynamics</span></a> <a href="https://infosec.exchange/tags/Systems" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>Systems</span></a> <a href="https://infosec.exchange/tags/SystemsTheory" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>SystemsTheory</span></a> <a href="https://infosec.exchange/tags/IEEE" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>IEEE</span></a> <a href="https://infosec.exchange/tags/WSD" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>WSD</span></a></p><p><a href="https://ieeexplore.ieee.org/document/10976483" rel="nofollow noopener" translate="no" target="_blank"><span class="invisible">https://</span><span class="ellipsis">ieeexplore.ieee.org/document/1</span><span class="invisible">0976483</span></a></p>
Jochen Fromm<p>Jay Forrester (at 21:00) about <a href="https://fediscience.org/tags/systemdynamics" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>systemdynamics</span></a> and why governments around the world are not able to stop <a href="https://fediscience.org/tags/climatechange" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>climatechange</span></a>:</p><p>"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]"<br><a href="https://youtu.be/6b4DmGtlOik?si=RXwBP8bajXX-FY5K" rel="nofollow noopener" translate="no" target="_blank"><span class="invisible">https://</span><span class="ellipsis">youtu.be/6b4DmGtlOik?si=RXwBP8</span><span class="invisible">bajXX-FY5K</span></a></p>
Jochen Fromm<p>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. <a href="https://fediscience.org/tags/ClimateChange" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>ClimateChange</span></a> is caused by consumption of non-renewable <a href="https://fediscience.org/tags/FossilFuels" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>FossilFuels</span></a> but it is just one aspect of a bigger crisis.

Power_to_the_People (he/him)<p>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.</p><p><a href="https://mastodon.social/tags/ClimateExtremes" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>ClimateExtremes</span></a>:AtTheAbyss <a href="https://mastodon.social/tags/SteveKeen" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>SteveKeen</span></a> <a href="https://mastodon.social/tags/climatechange" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>climatechange</span></a> <a href="https://mastodon.social/tags/systemdynamics" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>systemdynamics</span></a> <a href="https://mastodon.social/tags/feedbackloops" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>feedbackloops</span></a> <a href="https://mastodon.social/tags/tippingpoints" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>tippingpoints</span></a> <a href="https://mastodon.social/tags/amoc" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>amoc</span></a> </p><p><a href="https://youtu.be/U8pLrRkqbb0?si=smls8l-zKPTW7hDn" rel="nofollow noopener" translate="no" target="_blank"><span class="invisible">https://</span><span class="ellipsis">youtu.be/U8pLrRkqbb0?si=smls8l</span><span class="invisible">-zKPTW7hDn</span></a></p>
