Analysis of dynamical systems is one of the core issues in engineering problem solving. The purpose of the PSX project is to build a highly autonomous system for dynamical systems analysis, called PSX, which can investigate the characteristics of given dynamical systems without external assistance. The major issue in the PSX project is the integration of heterogeneous knowledge for dynamical systems analysis. In this paper, I discuss a couple of issues involved in the integration of heterogeneous knowledge, namely, the vertical and horizontal coordination problems. The vertical coordination problem is concerned with the coordination of knowledge units at different levels of abstraction. The horizontal coordination problem is concerned with the organization of widespread knowledge into a coherent body. I wil1 first discuss the vertical coordination problem on the basis of our experiences with PSX2NL, which analyzes the qualitative behavior of ordinary differential equations in the two-dimensional phase space. I demonstrate the complementary roles played by qualitative and quantitative analysis in PSX2NL. I will then present the notion of the knowledge community, a society of interacting agents, as a framework for horizontal coordination, and will discuss how the horizontal coordination problem can be handled within this framework.
