The aim of our article is a brief description of user interface modelling based on the graph transformations of conceptual data model. We use the lightweight formal method intended for deriving the user interface schemes by graph transformations from conceptual data model speci cations. The presented method based on graph transformation theory gives us a very visual tool for our objective. In o...

Strategic flexibility is increasingly gaining currency as a key element of strategy to manage corporate performance in rapidly changing, complex, and unpredictable business environments. This paper traces the conceptual development of strategic flexibility and presents an integrative theoretical model relating technology-and market-based strategic flexibility to enhanced firm level innovative c...

this paper describes a simple, physically-based conceptual model utilizing watershed drainage characteristics for rainfall-runoff simulation. this conceptual physiographic model is essentially based on the work of najafi (2003), which has led to a model compris-ing the main tributary subwatersheds and a single main channel subwatershed. the ki-nematic wave (kw) theory is used to describe flow o...

This study aims to identify the factors that contribute to the building of a firm’s innovative capacity and to assess the way in which this contributes to our understanding of how much this contributes to improvements in the firm’s performance. A conceptual model is proposed consisting of five separate dimensions: the firm; the entrepreneur; the external business environment; the firm’s innovat...

Weblogs have been proposed as a highly effective means for organizations to communicate with customers, suppliers, and employees. This paper provides a conceptual model of the relationships among weblog use, intellectual capital--the cumulative knowledge resources possessed by organizations-and both radical and incremental innovative capabilities. We argue that in enabling the transfer of knowl...

In this paper a conceptual model is defined that can be used for the innovative design of logistic systems. The model is constructed by using the systems approach in a formal and fundamental way. It turns out that the model complies with the ‘hard systems approach’, positioned in a trajectory according the ‘soft systems approach’. By this the model is an interdisciplinary tool that serves as a ...
