Planning global software development (GSD) projects is a challenging task, as it involves balancing both technical and business related issues. While planning GSD projects, project managers face decision-making situations such as, choosing the right site to distribute work and finding an optimal work distribution considering both the cost and duration of the project. Finding an optimal solution for...
Patterns are proven solutions that are applied to solve a recurring problem in a specific context. Pattern-based software design applies a suitable set of patterns to create a software structure that fulfills the requirements of the system to be built. The challenge is to find the useful patterns and apply them in an optimal way. This paper views pattern-based software design as a constraint satisfaction...
Current trends in information technology emphasize the need of flexible systems that are able to adapt to their changing environment. The aim of this paper is to develop an infrastructure for architecture level self-adaptation, and to study its applicability in the case of distributed systems. The approach is based on dynamically inserted and removed design solutions. The built infrastructure provides...
Genetic algorithms have become a popular heuristic technique to solve difficult search problems. However, in multi-objective problem solving, like software architecture generation, the basic variation mechanisms of genetic algorithms (mutation and crossover) tend to lead to mediocre solutions as the evolution favors balancing of several quality properties. In this paper, we explore the acceleration...
