Architecture-Based Planning of Software Evolution

Abstract

Software architecture allows us to make many decisions about a software system and analyze it even before it has been implemented, so as to make planned development possible. Similarly, architecture-based software evolution planning makes planned evolution possible by allowing us to make many decisions about the evolution of a software system and to analyze its evolution at the level of architecture design before software evolution is realized. In this paper, we develop a framework for architecture-based software evolution planning. It is done by defining various foundational terms and concepts, providing a taxonomy of software evolution plans, and then showing how to calculate values for various types of plans. By identifying and defining constituent foundational concepts, this conceptual framework makes precise the notion of 'architecture-based software planning'. By developing a value-calculation framework for software evolution plans, it also provides a basis for concrete methods for designing and evaluating evolution plans.

MORPH: a reference architecture for configuration and behaviour self-adaptation

“…[37]). Such techniques have been applied to construction of reconfiguration strategies in [7], [25], [16] Behaviour Problem Solver: This entity focuses on how to control the target system to satisfy a behaviour goal. In contrast to reconfiguration problems, the behaviour goal may not be restricted to safety and reachability (i.e.…”

“…Existing approaches to architectural adaptation (e.g. [2], [3], [4], [5], [6], [7], [8] incorporate elements from two key areas to enable runtime adaptation: Dynamic reconfiguration [9], [10], [11], [12], [13], [14], [15], [1], [1] and discrete-event control theory [14], [16], [17], [18], [19], [20], [21], [22], [23], [24]. The first, key for adapting the system configuration, studies how to change component structure and operational parameters ensuring that on-going operation is not disrupted and/or nonfunctional aspects of the system are improved.…”

Control Strategies for Self-Adaptive Software Systems

“…A number of architectural approaches for self-adaptive systems [Kramer and Magee 2007;Garlan et al 2004a;Dashofy et al 2002;Batista et al 2005;Oreizy et al 1999;Kang and Garlan 2014;Inverardi and Tivoli 2003;Braberman et al 2015] have been proposed. At the heart of many of such adaptation techniques, there is a component capable of designing at run-time a strategy for adapting to the changes in the environment, system and requirements (e.g., [Braberman et al 2015]).…”

Brittleness Analysis of Software Architecture based on Ant Colony Optimization

“…The research on dynamic architecture includes several languages, which support the structural description and the tools supporting the dynamic evolution process. The dynamic structure can accept or deny the changes inside or outside the system according the predefined policies and adjust itself to the changing situation [2,5].…”

“…The edge-set is { (1, 2), (1, 3), (2,4), (3,4), (4,5), (3,6), (6,3)}. Supposing after Delphi Method which is a structured communication technique relying on a panel of experts, the brittleness values are given to each edge represented in set D: =…”
