for more than three decades, oxidative coupling of methane (ocm) process has been comprehensively investigated as an attractive alternative for the commercially available ethylene production technologies such as ethane and naphtha cracking. developing a suitable catalyst and proper reactor feeding policy, reviewing and deploying the efficient methods in the separation and purification of the un...

The objective of this research is to develop a turbine blade investment casting cost advisor model to assist a blade designer in decision-making in a concurrent engineering environment. It is a microcomputer based cost estimating system that employs a manufacturing knowledge base. The concept of the manufacturing process for blade production by the investment casting method is used to develop t...

This study presents a new model for collaborative design that is analogous to electrical circuits with current (rate of design artifact synthesis and analysis), voltage (knowledge that drives the design process), and resistance (barriers to the exchange of design information). An electric analogy is used to capture the flow of information throughout the design process, it maps well to existing ...

The implementation of multi-agents systems aided collaborative and distributed design requires a deeper understanding of the real interactions between actors, inside of the multidisciplinary teams. In this view, it is considered that for the implementation of these systems, it is necessary to observe, model, and analyze this process with finer granularities levels. This study presents an approa...
