Contact rate for word of mouth
Jean-Jacques Laublé makes a good point about the traditional word-of-mouth product diffusion model not working in quite the same way for services such as telephone service contracts, internet service subscriptions, or rental cars. There are (at least) two reasons why the *service* word-of-mouth mode...

Contact rate for word of mouth
Hello Vittorio, To calibrate a word-of-mouth model, I typically break the word-of-mouth sales into real world pieces and then calibrate the pieces. In word of mouth models Ive built, Ive separated sales into two categories: word-of-mouth sales, and repurchases (by customers who are in the installed ...

Production and Sales Quotas
Today I read an article about Toyota surpassing Ford in vehicle sales to become the number two in total annual sales, behind GM. (However, Ford still leads Toyota in car sales, if Toyotas heavy truck division is excluded from the numbers.) Fujio Cho, president of Toyota, is generally considered to b...

Evolution of Language?
Martin, Regarding your query about using a model to explain the evolution of language, I believe you might be able to use the work of Jason Wittenberg and John Sterman in their paper, "Self-Organization, Competition, and Succession in the Dynamics of Scientific Revolution" The model and pa...

Traffic jams and congestion
Theres a nice article that could be used for an introduction that appeared in the Atlantic a couple years ago. The Physics of Gridlock http://www.theatlantic.com/issues/2000/12/budiansky.htm What causes traffic jams? The depressing answer may be nothing at all. As many of us may have suspected, rece...

Good Reading for System Dynamics

One of my favorite simulation books that doesnt often get read by sd people is: Serious Play: How the Worlds Best Companies Simula...

Niall, Usually, I believe that its a bad idea to run the beer game as a computer simulation. There have been dozens of attempts at converting the beer game into a computer simulation. In fact, Ive tried this a couple times myself. Few of these computer versions are very much fun. Thats because the b...

Attractiveness Multiplier
One nice feature of the multiplicative attractiveness function is that if any attribute goes to zero, the whole function returns a zero. So, if you are selling a product a product, the attractiveness of the product could be: Product Attractiveness = Availability Effect x Wait Time Effect x Price Eff...
