MSaaS (M\&S as a Service) is gaining momentum as an effective approach to bring the benefits of service-oriented architectures and cloud computing into the M\&S field, so as to enhance interoperability, composability, reusability and reduce the cost of M\&S efforts. Such significant advantages can be further enhanced by introducing automated model transformations that support the various phases of a M\&S effort, from simulation model building down to model implementation, deployment and execution. In previous contributions we have already addressed the use of automated model transformations that can be effectively adopted to provide simulation services for MSaaS platforms. This paper instead focuses on the automated development of modeling services for MSaaS, i.e., those services that allow platform users to easily build models in their own modeling language by use of a web-based user interface. Specifically, this work proposes an approach to automatically generate web-based visual editors from a metamodel that defines a given modeling language. Once generated, such editors can be made available on demand through a complete MSaaS platform, which also includes simulation services. The paper first describes the architecture of a MSaaS platform that includes modeling services, then illustrates the method for the automated development of web-based modeling services and, finally, gives a complete example application of the proposed method. {\textcopyright}2017 Society for Modeling \& Simulation International (SCS).

In a SOA context, service providers are strategically interested both to describe the performance characteristics of offered services, to better qualify their offer and gain a significant advantage in the global marketplace, and to predict the level of performance that can be offered to service consumers when building composite web services that make use of services managed by various service providers. This paper introduces a model-driven approach for integrating performance prediction into service composition processes carried out by use of BPEL (Business Process Execution Language for Web Services). The proposed approach is founded on P-WSDL (Performance-enabled WSDL), a performance-oriented extension of WSDL, the language for describing the information about service capabilities and invocation mechanisms. P-WSDL is a lightweight WSDL extension for the description of performance characteristics of a web service. The approach is illustrated by use of an example application to a composite web service for travel planning.
