Towards more effective simulation of minerals processing systems

Two aspects of the computer simulation of minerals processing systems were investigated in order to facilitate more effective use of simulation technology. A user-interface was designed and combined with an existing simulator executive, resulting in the implementation of a user-friendly microcomputer based minerals processing simulator, MicroSim. Ease of use was achieved by consideration of the needs of the user of such a program. This resulted in the use of graphical methods for information input and output. Efficient form-filling techniques were developed for numerical data entry and editing. Models for the carbon-in-pulp adsorption process and for continuous gold leaching were derived. The CIP models were derived using a population balance approach. The method of characteristics and the method of moments were found to be particularly useful in solving the resulting equations. Besides being important processes in themselves, the integration of these models into MicroSim provided valuable experience regarding the use of such models in a simulator.AC 201

Towards the on-line development of visual interactive simulation models

Reviews of previous work on visual interactive simulation, and on the interface between humans and computers were undertaken, the latter considering the physical and psychological aspects of the subject. Two simulation projects carried out in association with Rolls-Royce Aero Engines and the British Steel Corporation are described in detail. As a result of these projects and the review of previous studies, a major weakness in the technology of visual interactive simulation was identified: while the visual representation aids validation, verification, and experimentation, no facilities are provided to assist the analyst in the task of model construction. Simulation program generators are of proven use for non-interactive models, but a visual model requires a graphically oriented approach. The main section describes the design and implementation of a substantial extension to the simulation software developed at Warwick. This allows the design and development of displays to be carried out 'on-line', while preserving the one-to-one correspondence between simulation entities and their visual representation. It is suggested that this has the potential to significantly reduce the elapsed time taken to develop visual simulation models, while increasing the involvement of the user (or sponsor) in the modelling process, especially when 'pre-defined' entity types are used to minimise the amount of model- specific coding required. Finally, potential routes for the further development of visual interactive simulation are discussed, including the implementation of a 'simulation language' interpreter within the existing software. This would result in a system which was fully interactive, easing model development as well as experimentation
