内容説明
Jurgen Mihm builds a mathematical model of a complex distributed design project demonstrating how complexity inevitably arises from the interaction of simple components. He characterizes the dynamic behavior of the system analytically and with the aid of simulations, and he derives classes of managerial actions to improve performance dynamics.
