On model typing

mortality forecasting based on lee-carter model

over the past decades a number of approaches have been applied for forecasting mortality. in 1992, a new method for long-run forecast of the level and age pattern of mortality was published by lee and carter. this method was welcomed by many authors so it was extended through a wider class of generalized, parametric and nonlinear model. this model represents one of the most influential recent d...

Typing in Model Management

Model management is essential for coping with the complexity introduced by the increasing number and varied nature of artifacts involved in MDE-based projects. Global Model Management (GMM) addresses this issue enabling the representation of artifacts, particularly transformation composition and execution, by a model called a megamodel. Typing information about artifacts can be used for prevent...

Typing Model Transformations Using Tracts

As the complexity of MDE artefacts grows, there is an increasing need to rely on precise and abstract mechanisms that allow system architects to reason about the systems they design, and to test their individual components. In particular, assigning types to models and model transformations is needed for realizing many key MDE activities. This paper presents a light-weight approach to type model...

On Bun hed Typing

On bunched typing

We study a typing scheme derived from a semantic situation where a single category possesses several closed structures, corresponding to different varieties of function type. In this scheme typing contexts are trees built from two (or more) binary combining operations, or in short, bunches. Bunched typing and its logical counterpart, bunched implications, have arisen in joint work of the author...
