Automating the Object-Oriented Software Development Process: Workshop Report

Cost-effective realization of robust, adaptable and reusable software systems demands efficient and effective management of the overall software production process. Current object-oriented methods are not completely formalized and lack the ability of reasoning about the quality of processes and software products (artifacts). There is a need for new modeling formalisms, which enable the quantification of the required quality attributes and support the automation of the object-oriented development process (AOOSD). The ECOOP'98 AOOSD workshop was organized to identify the important issues in this direction

Integrating BON and Object-Z.

A significant limitation with object-oriented formal specification languages, such as Object-Z, is that they lack development and management processes, which can be used to guide the production of reliable, robust object-oriented systems. An integration of an object-oriented methodology, BON, and Object-Z is presented in order to add an industrially validated development process to Object-Z. An extensible CASE tool for BON is also described that supports the integration with an Object-Z code generation engine

Integration of an object formalism within a hybrid dynamic simulation environment

PrODHyS is a general object-oriented environment which provides common and reusable components designed for the development and the management of dynamic simulation of systems engineering. Its major characteristic is its ability to simulate processes described by a hybrid model. In this framework, this paper focuses on the "Object Differential Petri Net" (ODPN) formalism integrated within PrODHyS. The use of this formalism is illustrated through a didactic example relating to the field of Chemical Process System Engineering (PSE)

CONCEPTION OF PROVIDING THE OPERATIONAL DEVELOPMENT IN THE FUNCTIONING PROCESS OF INNOVATIVELY ORIENTED ENTERPRISES

Economic instability, continuous change of conditions, that innovatively oriented enterprises function in, complicate the achievement of planned results and decrease the efficiency of using strategic management of the development. Taking into account the aforesaid, the aim of the article is to elaborate a conception of providing the operational development in the functioning process of innovatively oriented enterprises, based on the complex of operational actions (economic functions), achieving tactic and strategic purpose-oriented results for transferring the economic system of an enterprise in the new development stage. According to research results, it was grounded, that the aim of functioning of innovatively oriented enterprises at realizing the operational development process forms as a combination of the innovatively oriented evolution of the economic system and the increase of the economic return for the further use in the development process. It was proved, that the development at the operational level is a process of purpose-oriented changes that provide transferring an enterprise to the new development stage. Such purpose-oriented changes are offered to be realized through realizing economic functions in the internal environment of an enterprise, directed not only on current functioning processes, but also development that allows to attain the sufficient economic return level. It was revealed, that it is expedient to realize them, based on using factors of production and management of economic relations both at the level “subject – object” and “object – object”, considering an innovatively oriented enterprise as an ecosystem. For this aim, its construction and structure are grounded; the characteristic of key complicated functional environments of components of an ecosystem is given. It was elucidated, that the economic evolution of an enterprise takes place through the change of stages (phases) of the functional development level, at each of them the complex of economic functions is realized, and the economic return is obtained according to an achieved position in the development process

Advanced software development workstation. Comparison of two object-oriented development methodologies

This report is an attempt to clarify some of the concerns raised about the OMT method, specifically that OMT is weaker than the Booch method in a few key areas. This interim report specifically addresses the following issues: (1) is OMT object-oriented or only data-driven?; (2) can OMT be used as a front-end to implementation in C++?; (3) the inheritance concept in OMT is in contradiction with the 'pure and real' inheritance concept found in object-oriented (OO) design; (4) low support for software life-cycle issues, for project and risk management; (5) uselessness of functional modeling for the ROSE project; and (6) problems with event-driven and simulation systems. The conclusion of this report is that both Booch's method and Rumbaugh's method are good OO methods, each with strengths and weaknesses in different areas of the development process

Indentifying Success Factors for Developing Web Applications: A Research Report

A survey for success factors of Web application development reveals that development methodologies, tools, and techniques are not considered as important by developers for the success of Web application development. Rapid application prototyping, ERD (entity relationship diagram), program flowchart, and application framework are more highly regarded than the object-oriented tools such as use case diagram, class diagram, object diagram, and sequence diagram. Developers focus more on maintainability and scalability than end users and management for evaluating the success of Web application development. Ambiguous user requirements, scope creeping, and lack of success metrics are evaluated as the most important issues for the failure of Web application development. Research results also indicate that developers need more help in communication, management, and control than the technology aspects of the development process. The overall findings point to flexible, simple, proven, participative, and management-oriented methodologies, tools, and techniques to address ambiguous and changing user requirements in the next generation development approaches for Web applications

Simplifying the construction of domain-specific automatic programming systems: The NASA automated software development workstation project

An overview is presented of the Automated Software Development Workstation Project, an effort to explore knowledge-based approaches to increasing software productivity. The project focuses on applying the concept of domain specific automatic programming systems (D-SAPSs) to application domains at NASA's Johnson Space Center. A version of a D-SAPS developed in Phase 1 of the project for the domain of space station momentum management is described. How problems encountered during its implementation led researchers to concentrate on simplifying the process of building and extending such systems is discussed. Researchers propose to do this by attacking three observed bottlenecks in the D-SAPS development process through the increased automation of the acquisition of programming knowledge and the use of an object oriented development methodology at all stages of the program design. How these ideas are being implemented in the Bauhaus, a prototype workstation for D-SAPS development is discussed

Model based fault diagnosis for hybrid systems : application on chemical processes

The complexity and the size of the industrial chemical processes induce the monitoring of a growing number of process variables. Their knowledge is generally based on the measurements of system variables and on the physico-chemical models of the process. Nevertheless, this information is imprecise because of process and measurement noise. So the research ways aim at developing new and more powerful techniques for the detection of process fault. In this work, we present a method for the fault detection based on the comparison between the real system and the reference model evolution generated by the extended Kalman filter. The reference model is simulated by the dynamic hybrid simulator, PrODHyS. It is a general object-oriented environment which provides common and reusable components designed for the development and the management of dynamic simulation of industrial systems. The use of this method is illustrated through a didactic example relating to the field of Chemical Process System Engineering
