Web services are defined by their reuse and seamless integration, and they communicate and integrate using standard like XML, WSDL, UDDI, and SOAP. The importance of web service composing is emphasized throughout the section. This technique involves combining many services to handle complicated tasks and improve performance. Static (design-time), dynamic (runtime) composing approaches, together with orchestrating, and the choreography, are the main categories in the field. Using state-of-the-art methods such as BPEL (Business Process Execution Language), Petri nets, and AI-based methods, the method of composition entails three critical phases: identifying services, selection, and scheduling. To demonstrate how to deal with dependency issues, mistakes, and optimizing, this section also discusses scheduling difficulties by combining Hierarchical Task Networks (HTN) with Partial Order Planning (POP). Being compliant with QoS (Quality of Service) standards is supported by dynamically services selection, which also facilitates strong, automatic business processes. Web services have the ability to streamline Business-to-Business (B2B) interactions, improve agility, and save costs, as highlighted in this section. Companies may improve the quality of products, speed delivery, and provide individualized services by automating workflows and using dynamically composition. The study suggests cutting-edge mathematical techniques to boost performance and shows how to put them to use in practical situations. Comparing the two methods at one service, the Proposed Method completes the work in 0.16 seconds, which is 98.67% quicker than the Conventional Method's 0.3 seconds are. Because it yields quicker responses without sacrificing efficiency, the Proposed Method is more accurate. With an increase in time for execution accuracy, the suggested technique is more effective and faster at one service. 2025 2025 17 33 10.54216/IJAACI.070102 https://www.americaspg.com/articleinfo/31/show/3479
