Integration has become a self-evident goal in today’s manufacturing enterprises. Since the late 1970’s, numerous major efforts have been launched worldwide to develop, employ, and deploy information technology for integration as a strategic weapon to compete in the global marketplace. Important results have been obtained, including Computer Integrated Manufacturing (CIM), and Concurrent Enginee...

Concurrent software for engineering computations consists of multiple cooperating modules. The behavior of individual modules is described by means on state diagrams. In the paper, the constraints on state diagrams are proposed, allowing for the specification of designer’s intentions as to the synchronization of modules. Also, the translation of state diagrams (with enforcement constraints) int...

Understanding program dependencies in a computer program is essential for many software engineering activities including program slicing, testing, debugging, reverse engineering, and maintenance. In this paper, we present a dependence-based representation called multithreaded dependence graph, which extends previous dependence-based representations, to represent program dependencies in a concur...

Abstract In recent years, space projects have evolved to faster and more variable projects. To adjust the design processes in accordance, new work methodologies arise, as Concurrent Engineering (CE). This working discipline is characterized by collaborative flux of information being improved a dedicated environment. CE has been recently adopted industry for preliminary phase spacecrafts other s...

The creation of reliable structural laminate composites for space applications requires precision design and manufacturing using an integrated, concurrent engineering approach. Since the final material characteristics are established at the same time the part or subassembly is fabricated, part design, fabrication development, and material characterization must proceed concurrently. Because comp...
