Quality Domain Specific Language (QDSL) is a model-driven approach providing a taxonomy, model, and visual editing tool for evaluating and benchmarking the quality of composite applications in cloud environments. Our language and associated modeling tool provide visual and textual means for constructing mathematical algorithms needed for computing aggregated quality assessment of cloud services. QDSL enables the illustration and definition of metrics, measurements and indicators, relationships for computation, and transformation functions that normalize the measurements into relative quality scoring. As a result, QDSL provides a structure that guides overall quality assessments. The computation algorithm is structured in a visual manner and associates the quality assessments graph with the structure of the cloud composite application in a hybrid environment. QDSL supports transformation from physical measurements into scoring comparative assessments of benchmarked provided IT solutions. This paper presents a basic model for QDSL and examples of usage. A prototypical eclipse EMF modeling tool of QDSL is used for communication, whereas commercial monitoring tools implement the instantiated models for evaluating service qualities.

Informed decision making and flexibility have grown to be important standard requirements in the field of business process modeling and design due to the emergence of intrinsically complex variables within the various business environments. Traditionally, researches on business process modeling and informed decision making have focused on the configurability of business process models. Our review of literature makes us confident that researches have considerably neglected the main drivers of flexibility and decisionmaking which have an extensive impact on business process flow. Such drivers form, in our opinion, cross cutting concerns that need to be extracted from the context of business processes. Context can include, but is not limited to, work force availability, work force experience, system failures, weather conditions, environmental hazards, and financial constraints. This paper presents a new general purpose methodology for modeling the context of business processes within different business domains as Open Aspects, and accordingly, deducing recommendations for improving the business process flow. We envision how context can be conceptualized as Open Aspects, how to classify the different contextual aspects into different business operational levels according to the goals of the business processes, and how to present business process flow recommendations based on the aspectized contextual facts.

With a variety of computer-aided design software and different operating platforms being applied in the enterprise, integration between heterogeneous systems increasingly attracts widespread concern and attention. In this paper, two levels of integration, information integration andapplication integration, are studied on the basis of system integration. This paper constructs enterprise integration platform based on WindChill to realize integration of information andapplication. And an example about platform is given and analyzed.

The application of virtual reality in architectural design has been the focus of attention. But the true 3D sense of immersion is still a dream for the most designers and clients when they watch the computer screen. A new computer stereo vision imaging system was constructed to help us obtain 3D visual of architectures and the implementation process became easier. And the application of advanced three-dimensional vision technology offered a more scientific, more interesting means of display and human-computer interaction. By using 3D stereo vision imaging system, all designers and users can obtain 3D visual observation of virtual buildings and virtual environments with a good sense of immersion at any time and any place.

Foundation pit engineering is a grey system, in which some information is known and some information is not known. It is hard to predict its deformation. In this paper, it is founded the deformation prediction system of foundation pit based on grey model GM(1,1). And the course of modeling, accuracy testing and correcting of the model in the system are realized with FORTRAN. The application in a real engineering shows that: the deformation prediction system of foundation pit has good applicability and high precision, which is useful as a sample for instructing informatization construction of foundation pit.

The development of 3-D modeling CAD system on production platforms is mainly discussed in this paper. A suitable petroleum platform design by using software is developed according to the design status of domestic production platforms and the principle of structural life cycle method. The research results have been successfully applied to the 3-D graphic design of production platforms. The design level of offshore platform has been remarkably raised and the design quality has been improved. The technology research on developing method, design analysis method, parameterized modeling method, information management method, version management and etc, and can also be applied to other engineering designs and have certain popularization value.
