Interest in the innovation of business models of companies in scientific research and man-agement practice has grown significantly over the past decade. It is critically important to analyze and understand the structure of the business model and its changes caused by strategic initiatives. Currently available approaches do not provide reliable guidelines, especially in uncertain and highly unstable situations associ-ated with rapid technological development. The approach presented in the article is based on the methodology of system modeling, which presents business models as complex systems with dynamic interdependencies, where intellectual capital plays a key role.

In a previous paper [G.Gomez Blanch and M.J.Fullana, 2017] we dened, in the frame of a geometro-dynamic approach, a metric corresponding to a lorentzian spacetime were the electron stationary trajectories in an hydrogenoid atom, derived from the de Broglie-Bohm model, are geodesics. In this paper we want to complete this purpose: we will determinate the remaining relevant geometrical elements of that approach and we will calculate the energetic density component of the energy-momentum tensor. We will discuss the meaning of the obtained results and their relationship with other geometro-dynamic approaches.Furthermore, we will derive a more general relationship between the lorentzian metric tensor and the wave function for general stationary states. The electron description by the wave function ψ in the Euclidean space and time is shown equivalent to the description by a metric tensor in an lorentzian manifold. In our approach, the particle acquires a determining role over thewave function, in a similar manner as the wave function determines the movement of the particle. This dialectic approach overcomes the de Broglie-Bohm model. And furthermore, a non local element (the quantum potential) is introduced in the model, that therefore goes beyond the relativistic locality.
