Implementation of computer software

The design of an expert system for use in solid/liquid separation involves considerations such as generality and completeness of both the available data and the ultimate software, programming language features and database structures and the control mechanisms that shape and restrict the 

The ability of the expert system software to give advice or educate the user in a congenial fashion and in the user s own terms is paramount, so that any psychological barriers to computer use are avoided. 

The software can ensure the correctness of input data as far as possible, utilise interactive graphics facilities to show the effects of changes in variables and/or allow the engineer access to calculations and make value judgements where these are peripheral to the expert system. Thus, to be most effective the software must be a well chosen mix of algorithm, expert system and input information from the engineer. 

It may be considered appropriate to perform pilot or semi-technical scale experiments provided the necessary equipment is available. Starting from the top of the equipment list, experiments should (ideally) be performed on each equipment type to determine whether the chosen cycle sequence is feasible and the desired results can be achieved in the most efficient manner. Sufficient experiments may be required to establish near optimum processing conditions and ensure successful operation over the range of potential process conditions encountered during variations in the feed properties. Equipment manufacturers can be consulted as appropriate. It is noted that performing pilot scale experiments is potentially very expensive. 

For the above situation to be satisfactory it is necessary to have consistent analysis procedures which facilitate the calculation of parameters such as
