Applying Concurrent Engineering in a company has a significant influence on the way information is dealt with. This influence is discernible for information on orders, products and resources. The impact of this influence on the product is determined, from which an extended role for the product information structure comes forward. On this product information structure, the overall product life c...

In this paper we present a case study on Auto-Focus, a tool prototype for the development of distributed and concurrent systems based on the concepts of the formal method Focus. We develop (specify , consistency-check and simulate) the controller of a pedestrian traac light using diierent graphical description techniques to illustrate an engineering process for concurrent systems.

Software infrastructure still one of the major difficulties in concurrent engineering environment especially in large scale projects where participants are geographically dispersed and belonging to different organizations. In this paper, we propose a new approach to build Virtual Enterprise software infrastructure that offers persistence, concurrent access, coherence and security on a distribut...

As the complexity of electronic systems grows, the traditional design practice, a sequential process, is replaced by concurrent design methodologies. A major advantage of concurrent design is that the feedback from software and manufacturing engineers can be easily incorporated into the design. The implementation of concurrent engineering methodologies is greatly facilitated by employing the la...

Program Slicing has many applications in software engineering activities. However, until recently, no slicing algorithm has been presented that can compute executable slices for concurrent logic programs. In this paper we present a dependence-graph based approach to computing executable slice for concurrent logic programs. The dependence-based representation used in this paper is called the Arg...

To ensure the science return while minimizing the cost and risk of a mission, a lifecyclewide concurrent engineering design process must be established. This paper describes the Virtual Mission Operation Framework (VMOF), which provides distributed modeling, simulation, and visualization services. The goal of the VMOF is to enable concurrent design of a mission system and operation of that syst...

More and more aspects of concurrency and concurrent programming are becoming part of mainstream programming and software engineering, as a result of several factors, such as the widespread availability of multi-core / parallel architectures and Internet-based systems. Java has been one of the first mainstream languages providing a firstclass native support for multi-threading, with basic low le...

The rapid growth in demand on information systems and the uncertainties associated with the development process for such systems has revealed problems such as inappropriate human resource management, poor quality, and serious delay. Traditional project management approaches emphasize the importance of scheduling, while careful allocation of resources across projects is critical and has a direct...

A concurrent engineering-oriented design database representation model (CE-DDRM) is introduced in this research for supporting various life-cycle aspects in concurrent design. In this model, concepts and behaviors of different design database modeling components, including entities, properties, relationships, tasks, and specifications, are defined at meta-class level. Design database is modeled...

This paper explores the performance of coupled development activities by proposing a performance generation model (PGM). The goal of the PGM is to develop insights about optimal strategies (i.e., sequential, concurrent, or overlapped) to manage coupled design activities that share a fixed amount of engineering resources subject to performance and deadline constraints. Model analysis characteriz...
