Here is a sample of public Insights made by Insight Maker users. This list is auto-generated and updated daily.
This model simulates the tradeoff between AI costs in resources and the benefits of increased efficiency and effectiveness over time, using adaptive learning principles. It demonstrates how AI development evolves through different stages early, growth, and mature -with changing rates of investment, efficiency gains, and resource utilization.
The model tracks how AI systems stabilize over time as efficiency gains become harder to achieve, leading to a more mature and balanced system of investment and performance. It aims to provide insights into real-world AI dynamics, showing how resources translate into efficiency improvements and how diminishing returns, learning saturation, and reinforcement learning affect long-term growth.
Ce modèle simule la dynamique d'une population dont la croissance est limitée par son environnement, un cas d'étude inspiré par la gestion des stocks de légine australe dans l'océan Austral.
Contrairement au modèle de croissance exponentielle (conditions idéales), la croissance de la légine n'est pas infinie. Les ressources (nourriture, espace) sont limitées et la compétition augmente avec la population. Ce phénomène, appelé densité-dépendance, crée une auto-régulation qui freine la croissance et la fait tendre vers une limite : la capacité de charge (K). De plus, cette population est soumise à une pression extérieure : la pêche.
Les Composants du Modèle :
Variable d'état : L'Effectif du stock (N) de légines, qui est au cœur du système.
Paramètres Fondamentaux : Les caractéristiques biologiques de la légine et de son milieu déterminent les paramètres de sa croissance. Vous pouvez régler ces paramètres avec les curseurs :
bmax et dmin : Les taux de natalité et de mortalité optimaux, quand la densité est faible.
ddb et ddd : L'intensité de la compétition. Ils mesurent à quel point la reproduction ralentit et la mortalité augmente quand la population devient trop dense.
Flux :
Les flux de Naissances (B) et de Morts (D) ne sont plus simplement proportionnels à N, mais sont maintenant régulés par la densité.
Un nouveau flux de sortie contrôlé par l'homme est ajouté : la Pêche (Fisheries).
Indicateurs : Le modèle calcule des propriétés "émergentes" cruciales pour les gestionnaires, comme le taux de croissance maximal (rmax) et la Capacité de Charge (K) de l'écosystème.
Votre Mission d'Exploration :
Votre objectif est de devenir un gestionnaire de pêcherie durable !
Commencez avec une pêche nulle (Fisheries = 0) pour observer la courbe de croissance logistique naturelle de la légine et identifier sa capacité de charge K.
Introduisez ensuite un effort de pêche modéré. Quel est son impact sur la taille de la population à l'équilibre ?
Explorez différentes intensités de pêche pour trouver le Rendement Maximal Soutenable (RMS) : la plus grande quantité de poissons que vous pouvez pêcher chaque année sans provoquer l'effondrement du stock. Cliquez sur "SIMULATE" et gérez votre ressource !
Use a bathtub model to investigate the manner in which inflows and outflows govern the quantity of a stock. Extend the structure to create and investigate the relationships of a goal seeking balancing loop.
Collapse of the economy, not just recession, is now very likely. To give just one possible cause,
in the U.S. the fracking industry is in deep trouble. It is not only that most
fracking companies have never achieved a free cash flow (made a profit)
since the fracking boom started in 2008, but that an already very weak and unprofitable oil industry cannot cope with
extremely low oil prices. The result will be the imminent collapse of the
industry. However, when the fracking industry collapses in the US, so will the American
economy – and by extension, probably, the rest of the world economy. To grasp a
second and far more serious threat it is vital to understand the phenomenon of ‘Global
Dimming’. Industrial activity not only produces greenhouse gases, but
emits also sulphur dioxide which converts to reflective sulphate aerosols in the
atmosphere. Sulphate aerosols act like little mirrors that reflect sunlight
back into space, cooling the atmosphere. But when economic activity stops, these
aerosols (unlike carbon dioxide) drop out of the atmosphere, adding perhaps as
much as 1° C to global average temperatures. This can happen in a very short period
time, and when it does mankind will be bereft of any means to mitigate the
furious onslaught of an out-of-control and merciless climate. The data and the unrelenting
dynamic of the viral pandemic paint bleak picture. As events unfold in the next few months, we may discover that it is too late to act, that our reign on this planet has, indeed, come to an abrupt end?

This model simulates the population growth in the city of Toronto measured using birth and death rates as well as the rate of people moving in and out of the city. The city's population is the main stock measured in people, while the growth flow is measured in people/year. The carrying capacity represents the maximum potential population that the city's housing capacity could accommodate.
