Simulation could be used to reveal complex dynamic behavior of enterprise, especially for playing out dynamic what-if scenarios, in determining enterprise's response to a change. Instead of relying on guidelines for simulating prescriptive models of enterprise as in other approaches including...

Software cost estimation is an important step that decides upon the effective manpower, schedule, pricing, profit and success for executing any medium to large sized project. Depending upon the underlying development methodology (e.g., code-centric, model-driven, product-line etc.) and past experience, every enterprise follows some cost estimati...

Enterprises are complex heterogeneous entities consisting of multiple stakeholders with each performing a particular role to meet the desired overall objective. With increased dynamics that enterprises are witnessing, it is becoming progressively difficult to maintain synchrony within the enterprise for it to function effectively. Current practice...

Development and maintenance of enterprise systems is becoming more difficult due to change drivers along multiple interconnected dimensions. It is advisable to model the enterprise first and analyze it for potential concerns. For modeling enterprises, ontologies have been considered apt and have been used in the past for the same, but application o...

Data center and cloud providers are responsible for provid- ing services such as storage or retrieval for large amounts of (customer owned) data by using databsae management systems (DBMS). Service provision implies a specific quality of service regarding performance or security. Another factor of increasing importance is energy consumption. Althoug...

While a considerable amount of research on enterprise ontologies exists, work showing how to use ontologies for enterprise architecture (EA) analysis is scarce. We present our ongoing work on creating analyzable enterprise models using EA-based ontological representation. Our contributions are twofold: first, we show how an existing EA modeling lan...

With continued increase in business dynamics, it is becoming increasingly harder to deliver purpose-specific business systems in the ever-shrinking window of opportunity. Code-centric software product line engineering (SPLE) techniques show unacceptable responsiveness as business applications are subjected to changes along multiple dimensions that...

Metrics measurement for cost estimation in model-driven engineering (MDE) is complex because of number of different artifacts that can potentially be generated. The complexity arises as auto-generated code, manually added code, and non-code artifacts must be sized separately for their contribution to overall effort. In this paper, we address measur...

Aspect orientation has been used to improve the modularization of crosscutting concerns that emerge at different levels of software abstraction. Although initial research was focused on imparting aspect-oriented (AO) capabilities to programming languages, the paradigm was later on extended to software artifacts that appear at higher levels of abstr...

Protecting the environment by saving energy and thus reducing carbon dioxide emissions is one of today’s hottest and most challenging topics. Although the perspective for reducing energy consumption, from ecological and business perspectives is clear, from a technological point of view, the realization especially for mobile systems still falls behi...

Aspect-oriented programming (AOP) provides assistance in modularizing concerns that crosscut the boundaries of system decomposition. Aspects have the potential to interact with many different kinds of language constructs in order to modularize crosscutting concerns. Although several aspect languages have demonstrated advantages in applying aspects...

Most mobile and embedded devices are battery powered. Hence, their uptime depends on the energy consumption of the used components. Developers made severe effort to optimize hardware components in order to reduce their energy consumption. However, in this paper we show that one also has to consider energy awareness in terms of software. In this stu...

Certain patterns are observed in the implementation of the application-level Checkpointing and Restart (CaR) mechanism across myriad of applications. These patterns indicate that a higher level of...

Domain-Specific Modeling (DSM) allows domain experts to concentrate on the essential characteristics of a problem space without being overwhelmed by the complexities that may occur in the solution space. DSM is focused on the creation of a metamodel for a specific domain, from which instances pertaining to specific configurations of that domain can...

This paper describes an approach that combines model engineering with program transformation techniques to construct aspect weavers for general-purpose programming languages. The front-end of the weaver uses a high-level language (i.e., an aspect language) to specify aspects and is designed with a metamodel-based approach using the AMMA toolsuite....

A major difficulty in compiler development regards the proper modularization of concerns among the various compiler phases. The traditional object-oriented development paradigm has difficulty in providing an optimal solution towards modularizing the analysis phases of compiler development, because implementation of each phase often crosscuts the cl...

A common trend in programming language specification is to generate various tools (e.g., compiler, editor, profiler, and debugger) from a grammar. In such a generative approach, it is desirable to have the definition of a programming language be modularized according to specific concerns specified in the grammar. However, it is often the case that...

During language evolution, compiler construction is usually performed along two dimensions: defining new abstract syntax tree (AST) classes, or adding new operations. In order to facilitate such changes, two software design patterns (i.e., the inheritance pattern and the visitor pattern) are widely used to help modularize the language constructs. H...
