چکیده مقاله :
امروزه تغییرات مداوم در نیازمندیهای مشتریان به عنوان اصلیترین چالش پیش روی سازمانها است، معماری سرویسگرا به عنوان یک راهحل عملی برای رفع این مشکل برای سازمانهای سرویسگرا مطرح میشود. در معماری سرویسگرا انتخاب و ترکیب سرویسها برای پاسخگویی سریع به نیازمندیهای پیچیده مشتریان در دسترس سازمانهای سرویسگرا قرار میگیرد. سازمانها برای پاسخگویی سریعتر به نیازمندیهای پیچیده و متغیر مشتریان از سرویسهای آماده و برونسازمانی استفاده میکنندکه یکی از فناوریهای نوظهور در این زمینه وبسرویسها هستند. با گسترش تمایل سازمانها به استفاده از وبسرویسها، به مرور زمان تأمینکنندگان وبسرویسها افزایش پیدا کردند و به همین دلیل وبسرویسهایی با عملکرد یکسان و ویژگیهای کیفی متفاوت گسترش یافتند، بنابراین مسئله انتخاب وبسرویس با بهترین ویژگی کیفی برای سازمانها اهمیت پیدا کرد. از طرفی سازمانها تنها با یک وبسرویس نمیتوانند نیازمندیهای پیچیده مشتریان را پاسخ دهند، به همین دلیل نیازمند ترکیب چندین وبسرویس با هم هستند. از طرفی دیگر با افزایش وبسرویسها با عملکردهای متفاوت، در ترکیب آنها، همبستگی، وابستگی و ناسازگاری بین وبسرویسها نیز گسترش مییابد ولی تاکنون روشی ارائه نشده که وبسرویسهای برتر را بر اساس ویژگیهای کیفی انتخاب کند و ترکیب آنها با هم، وابستگی، ناسازگاری و همبستگی بین وبسرویسها را نقض نکند. در این مقاله سعی میکنیم از روشهای قبلی که به وابستگی یا ناسازگاری یا همبستگی در حالتهای ساده ترکیب وبسرویسها پرداختهاند، استفاده کنیم و یک روش جامع پیشنهاد دهیم تا این که حالتهای پیچیدهای که از ترکیب وبسرویسها ممکن است رخ دهد را نیز پشتیبانی کنیم و وبسرویس مرکب مناسب را از نظر ویژگیهای کیفی با در نظر گرفتن وابستگی، ناسازگاری و همبستگی بیابیم.
Today, the continuous changes in customer requirements are the main challenges faced by enterprises. Service-oriented architecture is considered as a practical solution to solve this problem for service-oriented enterprises. In the service-oriented architecture, selection and composition of services to quickly respond to complex customer requirements is available to service-oriented enterprises. Enterprises use ready-to-use and outsourced services to respond more quickly to the complex and changing needs of customers. One of the emerging technologies in this area is web services. By expanding the desire of enterprises to use web services, overtime web services providers increased. For this reason, Web services with the same functionality and different qualities were expanded. Therefore, the issue of choosing a web service with the best quality for enterprises is important. On the other hand, enterprises with only one web service cannot meet the complex requirements of customers; therefore, they need to composite multiple web services together. In addition, with the increase of web services with different functions, correlation, dependency and conflict between Web services also expand in their composition. But so far, there is no way to choose the best web services based on the quality of service(QoS) and also their composition does not violate the dependency, conflict and correlation between web services. In this paper, we try to make use of previous methods that consider dependency or conflict or correlation in simple modes of web services composition. We will improve all these methods in a comprehensive approach and support complex situations that may arise from the composition of web services and find the suitable composite web service by considering dependency, conflict, and correlation between Web services.
