Weasel program is a good point to start thinking about behavioural evolution of manufacturing companies.

Let say, -hypothetically- we have a company which is producing some products with a set of tools (i.e. best practices). This toolset includes limited number of tools (say genomes) and called genetic combination. Accordingly, this company is being exist in a limited business environment. The business environment has a limited set of environmental factors (e.g. common industrial best practices' requirements), called ''environmental set''. In each step, the company evolves and try to adapt to the environment.

As a beginning, we can imagine that the environment can be in one of two different state in the proposed model of simulation: (1) Environmental set is not changing, it is in a steady state; (2) Environmental set is changing randomly in each step, it is in a transient period. I am going to call these two situations as scenarios.

Scenarios

1. Environmental set is fixed.

2. Environmental set is changing over time regardless of the change of the genetic combination. (not shown here)
