Numerical simulations of various reactors for the production of xylose from hardwood hemicellulose by dilute sulfuric acid hydrolysis have been developed to analyze the effects on reactor performance of heat and mass transfer as well as reaction kinetics. An economic objective function representing the incremental cost of producing a 10% xylose solution for fermentation to ethanol was calculate...
The need for higher performance electronics for space and defense applications has driven the development of InP heterojunction technologies. For the past 10 years, TRW has been developing InP HBT and HEMT technologies for mission critical applications [1– 3]. Consistent and continuous improvements in the basic MBE structure and process technology have enhanced device and circuit performance, p...
Fluid flow models have been used in performance evaluation of production, computer, and telecommunication systems. Currently, a general methodology to model and analyze a given continuous flow production system is not available. In order to develop a general methodology to analyze Markovian continuous material flow production systems with a finite buffer, we modelled the fluid flow system as a ...
The paper will present the successful realization of simulation based manufacturing planning and control in electronics production. The principle has been implemented in various applications as supplementary decision aid in connection with ERP systems. A theoretical model of virtual and real time explains relations between simulation and production planning. In all cases the discrete event simu...
The lack of proper analytical models of some production processes prevents us from obtaining proper values of process parameters by simply computing optimal values. Possible solutions of control problems in such areas of industrial processes can be found using certain methods from the domain of artificial intelligence: neural networks, fuzzy logic, expert systems, or evolutionary algorithms. Pr...
