On top of that, there is a need to consider the nature of dependencies between enterprises on a supply chain network in order build a model based on a realistic view of the world. This paper describes the attempts made so far in the Department of Computing and Information Systems at the University of Sunderland to develop a model which takes into account the relationships of enterprises, as well as their effects on all the levels of operations (tactical, operational, strategic). The objective is to discuss a decision support tool which can assess the impact and the effects on a supply chain every time an enterprise enters or leaves the chain.","PeriodicalId":177805,"journal":{"name":"Proceedings Technology of Object-Oriented Languages.

The projects were analyzed in order to find out metrics which would be suitable for early estimation of quality.

The system parts are modeled using object-oriented technology, such that not only are the static features of the components encapsulated, but also are the dynamic design states. A system is designed by empowering each object class with design autonomy, thus leading to a distributed-controlled environment where objects actively seek to synthesize themselves in parallel using messages. System synthesis is accomplished and related problems are solved by eight different kinds of messages passed among the objects. Problems inherent to parallel design, such as emptiness and deadlock are also solved.","PeriodicalId":177805,"journal":{"name":"Proceedings Technology of Object-Oriented Languages. TOOLS 27 (Cat.

We therefore propose MVIm (Model-View-Interface manager) model to escape from this problem. Since the interface manager indirectly combines between middleware, we can effectively use the middleware without bad interference.","PeriodicalId":177805,"journal":{"name":"Proceedings Technology of Object-Oriented Languages.

Various replication schemes have been proposed which are based on two streams of techniques, namely passive replication and active replication. The paper focuses on two implementation approaches of the passive primary-backup scheme, remote method invocation approach and replica-proxy approach, using Java RMI and Java network packages respectively. Issues addressed in the paper also include: the primary-backup protocol; restarting a failed server at any site; and a general naming service for the maintenance of dynamic memberships of replica groups. Finally, performance studies based on two implementation approaches are given.","PeriodicalId":177805,"journal":{"name":"Proceedings Technology of Object-Oriented Languages. TOOLS 27 (Cat.

However mobile computing environments are characterized by significant and rapid changes in supporting infrastructure. They offer one of the most diverse and challenging environments in which to build distributed systems. We evaluate various communication styles operating in conventional distributed systems concerning mobile computing environments. We argue that those connection-oriented paradigms are not well suited to operating in a mobile environment and instead propose a framework of extended event service on the event-based communication paradigm. The QoS control of event delivery and the agent coordination based on a group model are discussed.","PeriodicalId":177805,"journal":{"name":"Proceedings Technology of Object-Oriented Languages.

The system conforms to a subset of the Geospatial and Imagery Access Services (GIAS) specification from the U.S. National Imagery and Mapping Agency (NIMA), which defines an object-oriented application programming interface (API) using the Common Object Request Broker Architecture (CORBA) for remote access to the image server. The GIAS specification is being explored by the military in both the U.S. and Australia as a means for creating widely accessible imagery repositories, and also provides a convenient API for interfacing to repositories of geospatial images, such as satellite data archives, for a variety of commercial and research applications. Our prototype GIAS implementation was developed using StudioCentral from Silicon Graphics Inc., which provides a set of C++ class libraries for building digital multimedia repositories. We discuss the issues and problems involved in developing this system using CORBA, Java and C++ native methods, within the constraints of the GIAS specification.","PeriodicalId":177805,"journal":{"name":"Proceedings Technology of Object-Oriented Languages.
