Abstract: | Planning and production optimization within multiple mines or several work sites (entities) mining systems by using fuzzy
linear programming (LP) was studied. LP is the most commonly used operations research methods in mining engineering. After
the introductory review of properties and limitations of applying LP, short reviews of the general settings of deterministic
and fuzzy LP models are presented. With the purpose of comparative analysis, the application of both LP models is presented
using the example of the Bauxite Basin Niksic with five mines. After the assessment, LP is an efficient mathematical modeling
tool in production planning and solving many other single-criteria optimization problems of mining engineering. After the
comparison of advantages and deficiencies of both deterministic and fuzzy LP models, the conclusion presents benefits of the
fuzzy LP model but is also stating that seeking the optimal plan of production means to accomplish the overall analysis that
will encompass the LP model approaches. |
