Introduction
The aim of L.S.L.P.S. is to provide the mineral industry in
particular and other industries in general, with specialist Linear and Mixed Integer
Programming model building, maintenance, advice and guidance services.
Large integrated mining and metallurgical complexes are
modelled in their entirety in order to avoid sub-optimisation. In the
literature this is referred to as the SYSTEMS or HOLISTIC APPROACH TO PLANNING.
The planning of the "holistic mass balance
performance" is optimised in terms of its objective function, typically,
N.P.V. (Net Present Value). The "holistic mass balance performance"
is that mass balance performance which is determined over ALL possible
combinations of plant, equipment, machinery, circuits, men and money in the
planning process of exploiting the ore body:- ore resources (measured,
indicated and inferred), through mining and beneficiation, up to the physical point
of sale of the final product(s).
This way the metallurgical supply chain value network can be
optimised down to the detailed levels of stoicheiometry, metallurgical mass
balance, slag chemistry and heat balances.
L.S.L.P.S. has, since its inception in 1989, expanded the
scope of its capabilities to not only model building, but also to project work
in the fields of:-
• Techno-economic studies
• Business expansion and
contraction studies
• Rationalisation studies
• Strategic planning
• Feasibility studies
• Production planning
• Contingency planning
The model building approach applied by L.S.L.P.S. is one of
USER FRIENDLY DECISION SUPPORT. The model is placed in the hands of the
decision maker using spreadsheet front-ends as an easy-to-use interface to
models. Matrix generation is data driven and the optimal solution is reported
in user jargon.
Client information is always regarded as confidential and
L.S.L.P.S. enters into confidentiality agreements with clients whenever
required.
L.S.L.P.S. is an agent for Haverly
Systems Incorporated and the following software is made use of in our
solutions:-
• H/CPLEX
• H/XPRESS (parallel)
• H.S.L.P.
• OMNI Plus
Note:- Applications described in this website are likely to
be subject to customisation prior to being applied to other mining and
metallurgical complexes. Regard these applications as building blocks, which
can be adapted and regrouped with a view to constructing new holistic
optimisation models.
