Legacy Software Re-Engineering Technology (LSRET)

Currently, one of the important tasks of the economic policy of Russia is the formation of a hightech image of the national economy, capable of effective functioning in the changing global geopolitical and geoeconomic conditions. In this context, the issue of revitalization of mechanical engineering, which plays a key role in the development of the country’s economy, is of particular relevance. This sector is a link between scientific and technological progress and the level of provision of domestic producers with domestic machines and equipment, allowing them to produce competitive products and to a lesser extent depend on the state of the external environment. The example of the developed countries of the world shows that the development of advanced engineering technology significantly increases the efficiency of the national economy, helps to accelerate its growth. At the same time, in Russia, in order to unleash the scientific and technical potential and activate engineering, it is necessary to initiate modernization processes in it. Based on the foregoing, the purpose of the study is to analyze the state of Russian engineering from the position of its role in the country’s economy. It is shown that at present a significant barrier to the development of this sector is the predominance of imported equipment, due to technical and operational characteristics, often superior to domestic counterparts.

Cathedrals are buildings of cultural weight. They have frequently drawn attention from architectural historians, especially in the medieval era, as examples of Great Churches: leaders in artistic development or pioneers in engineering technology. When one thinks of Gothic buildings in <?page nr="300"?>particular, it is the cathedral that comes foremost to mind as example. Salisbury, Canterbury, York, and their fellows continue to draw both scholarly attention and popular attraction.

Candidate Identification

Identification of web service candidates in legacy software is a crucial process in the reengineering of legacy systems to service oriented architecture. Researchers have proposed various automatic and semi-automatic methods for this purpose, some of which have proved to be quite efficient, but there are still certain gaps which need to be addressed. This article discovers the strengths and weaknesses of previous methods and develops a method with improved service candidate identification performance. In this article, service identification is considered as a search and optimization problem and a firefly algorithm is developed accordingly to give high-quality solutions in reasonably short times. A filtering method is also developed to remove excess modules (false positives) from the algorithm outputs. A case study on a legacy flight reservation system demonstrates the high reliability of the outputs given by the proposed method.
