A new model for the design of the city gas distribution network has been presented. On the basis of mass flow rates and pressure balances a nonlinear system of equation is obtained. A method for solving the latter is outlined which gives accurate results. Also, this method, when compared to the other accessible ones, takes less computer time. Finally in this method the actual length of netw...

railway service terminals are the places of a railway network usually equipped with costly technology based on highly complicated technological procedures demanding a high degree of coordination and control skills. design of these systems and the organization of their operation should facilitate reaching to the required capacity together with high quality of service processes as well as minimal...

developing reliable yet flexible software is a hard problem. although modeling methods enjoy a lot of advantages, the exclusive use of just one of them, in many cases, may not guarantee the development of reliable and flexible software. formal modeling methods ensure reliability because they use a rigorous approach to software development. however, lack of knowledge and high cost practically fo...

design process is one of the main processes practiced in engineering. in this paper, after demonstrating the place of engineering among the topics discussed about technology, design process is studied from the perspective of three different models. the first model, vincenti’s model, provides an abstract explanation of the design process; the second model, bucciarelli’s model, has a sociological...
