Javier is back, now including the demand for his art in the production planning. Sorry for the long video, I hope it will at least be watched by the #Julia enthusiasts or the #orms people out there. Maybe #microeconomics people will enjoy it too. Once more I use #pluto and #jump.

When planning the production, in our last video, we ignored the demand for the products. In this video, we will evaluate two strategies to include the demand into the model.
The first strategy is to have a sale of excess products. In this case, we have a piecewise revenue function, and we use some modeling tricks to model it into a mixed-integer linear program.
The second strategy is to consider the price at which we sell things to be a decision variable as well and to model the demand as a function that depends on the price linearly. This case leads to a very interesting conclusion about the nature of demand satisfaction.

In Brazil, when we got overwhelmed with our studies, we would say that we were thinking about dropping out and selling art on the beach.
Well, if you did that, could you optimize your art production?

Check out how to model and solve that using #JuliaLang and #JuMP: https://youtu.be/IOUi1juD5HQ

Hey Science Mastodon: can anyone point me towards work on logistic-like growth of a population modeled as one growing subpopulation whose individuals sometimes transition into a nongrowing subpopulation?

Hello! This is my brief #introduction. I'm a professor of #economics at Rice university. I use #mathematicalmodeling to inform science-based policy. My research involves the economics of emerging infectious diseases, climate and the energy transition, and using #gametheory to study symbiotic relationships in #ecology. In #puremath I have been working on #fixedpoint theorems for locally contractive set-valued maps. I enjoy travel, kayaking, reading, and dreaming of classic cars.

Cheers!

#introduction

Hi all, I'm a PhD candidate at Yale University.

I am interested in host-parasite #coevolution in #microbial communities, especially #bacteria and #phage. I'm also interested in building high-throughput methods, both in the lab and in #rstats.

I use a combination of #ExperimentalEvolution and #MathematicalModeling throughout my work
