The paper discusses a cooperative engineering design process in which the design teams cooperate on design of engineering subsystems in order to optimize the performance of the entire system. We describe models for software systems supporting such engineering design. The software system consists of several coordination software modules that allow design teams to cooperate in the process of spec...

A brief background to the development of the rock engineering design process is given, showing that since the development of the science of mathematics, deterministic methods have been used to perform various calculations. The variability of rock properties and support characteristics have always been known. However, they were not explicitly used in design but compensated for by the use of a sa...

methyl tertiary butyl ether (mtbe) is known as a promising substitute for tetra ethyl lead (tel) in order to increase the octane number of gasoline. mtbe process, as many other processes, has two distinguished section, namely reaction section and separation section. in this paper we focus only on synthesis and optimization of separation section of this process. in order to achieve this objectiv...
