Darbo objektas: Lietuvos kūno kultūros akademijos teikiamų baseino komercinių paslaugų pasirinkimo ypatumai. Aktualumas: paslaugoms būdingi kiti ypatumai nei materialinėms vertybėms. Šiuos ypatumus lemia paslaugų verslo prigimtis ir paslaugų savybės: jų neapčiuopiamumas, nedalijamumas (t. y. neatskiriamumas nuo teikimo šaltinių), epizodiškumas, kokybės nepastovumas ir kt. Paslaugų savybių visuma lemia nevienodą paslaugų kokybę ir sudėtingą jos vertinimą. Norint įvertinti paslaugų kokybę, pirmiausia būtina išsiaiškinti, kaip ją suvokia klientai. Tik tuomet paslaugų teikėjas galės kontroliuoti ir koreguoti šiuos vertinimus norima linkme. Neatsižvelgiant į klientų nuomonę dėl kokybės, galima suklysti, o išleisti pinigai ir laikas bus prarasta investicija. Paslaugos šiandien atsidūrė ekonominės veiklos dėmesio centre: jos tampa privaloma priemone siekiant patenkinti svarbiausius norus bei reikmes ir kelti visuomenės gerovę (Kindurys, 1998), tačiau ekonominiu aspektu LKKA teikiamos baseino paslaugos šiame darbe neanalizuojamos. Paslaugos pasirinkimo motyvai kiekvieno vartotojo yra individualūs. Vartotojo reikšmingumas įpareigoja paslaugų teikėjus nuodugniai išanalizuoti visus veiksnius ir imtis reikiamų sprendimų, susijusių su paslaugų kokybės tobulinimu. Todėl norint teikti atitinkamos kokybės paslaugas, svarbu žinoti, kokie motyvai vartotojams yra svarbiausi renkantis paslaugų teikėją ir kokiais kriterijais remdamasis jis suvokia gaunamos paslaugos kokybę.

Relevance: Services, compare it to material values, are incident to particular peculiarities. Those peculiarities are determined by the nature of service business, services characteristics, for instance, its impalpability, indivisibility that is inherency of its rendering derivation, transience and impermanence of their quality and etc. Totality of services characteristics determine complicated quality of services and even more complicated its evaluation. First of all on purpose to evaluate the quality of services it is necessary to ascertain, how clients perceive it themselves. At that point the services supplier can control these evaluations and shift it on desirable direction. Irrespective of clients’ opinion in point of quality, could be initiated deceptive actions while expended money and time would be meaningless investment. Services appeared in the center of economical brief: it’s become compulsory implement on purpose to satisfy the main desires and needs also to increase public welfare (Kindurys, 1998), however services provided by LAPE swimming pool will not be analyzed in economical aspect. Services organization, which provides qualitative services, gains the acceptance and loyalty of consumers, increases market share, forms and maintains competent personnel and becomes less exposed concerning the strife of prices...

No. of bitstreams: 1 arquivototal.pdf: 2340814 bytes, checksum: bdce9ccd956442015a53d57f06a00741 (MD5) Previous issue date: 2016-08-23 / Software Engineering is a discipline that encompasses all aspects of the production of a software system, from the early stages of the system specification to maintenance, when the system is already being used. A very interesting area in Software Engineering is software reuse, which impacts positively on reducing time, costs and risks in software development processes. Therefore, it can be stated that software reuse improves not only the software development process, but also the product itself. One of the main approaches for software reuse is service oriented development, which adopts the Service-Oriented Architecture (SOA) paradigm. In SOA, services represent a natural evolution of component-based development, and therefore can be defined as loosely coupled, reusable software components, that encapsulate discrete functionality, can be distributed and remotely accessed through coding. It is important to highlight that while SOA is an architectural paradigm for developing software systems, Web Services represent the most widely existing technology adopted to implement SOA exploring protocols based on Internet standards and on XML. With the growth of the market and the use of web services, the tendency is always increase the number of services available for assembly applications in different contexts, making impractical the task of manually selecting the services required to compose a software system. Consequently, one can state that the effort needed to select the required services tends to increase more and more, creating a problem with a large and complex search space, making it necessary the automation of the selection process based on metaheuristic search techniques. In this context, the proposed work aims to automate the web services selection process using techniques of Search-Based Software Engineering, in which the selection strategy is guided by structural and functional metrics that have the purpose of evaluating the similarity between the specifications and respective implementations of candidate services as well as their dependencies, thus reducing the effort of adaptation and integration of web services developed by different suppliers. / Engenharia de Software é uma disciplina que engloba todos os aspectos da produção de um sistema de software, incluindo desde os estágios iniciais da especificação do sistema até sua manutenção, quando o sistema já está sendo utilizado. Uma área de estudo bastante interessante da Engenharia de Software é o reuso de software, que impacta positivamente na redução do tempo, dos custos e dos riscos provenientes de um processo de desenvolvimento de software. Portanto, é possível afirmar que o reuso de software melhora, não apenas o processo de desenvolvimento de software, mas também o próprio produto. Uma das principais abordagens de reuso de software é o desenvolvimento orientado a serviços, que adota o paradigma da Arquitetura Orientada a Serviços (SOA – Service-Oriented Architecture). No paradigma SOA, serviços representam uma evolução natural do desenvolvimento baseado em componentes, e, portanto, podem ser definidos como componentes de software de baixo acoplamento, reusáveis, que encapsulam funcionalidades discretas, que podem ser distribuídos e acessados remotamente de forma programática. É importante destacar que, enquanto SOA é um paradigma arquitetural para desenvolvimento de sistemas de software, serviços web (web services) representam a tecnologia existente mais amplamente adotada para implementar SOA explorando protocolos baseados em padrões da internet e em XML (eXtensible Markup Language). Com o crescimento do mercado e utilização dos serviços web, a tendência é sempre aumentar o número de serviços disponíveis para montagem de aplicações em diferentes contextos, tornando impraticável a tarefa de selecionar de forma manual os serviços requeridos para compor um sistema de software. Consequentemente, é possível afirmar que o esforço necessário para selecionar os serviços requeridos tende a aumentar cada vez mais, gerando um problema com um grande e complexo espaço de busca, tornando necessária a automatização do processo de seleção baseada em técnicas de busca metaheurística. Neste contexto, o trabalho proposto visa automatizar o processo de seleção de serviços web utilizando técnicas da Engenharia de Software Baseada em Buscas, cuja estratégia de seleção é orientada por métricas funcionais e estruturais, que têm o propósito de avaliar a similaridade entre as especificações e as respectivas implementações dos serviços candidatos, bem como as suas dependências, reduzindo assim o esforço de adaptação e integração de serviços web desenvolvidos por fornecedores distintos.
