5 CONCLUSION
Aiming at the problem of cost forecasting in modern
coal enterprises, this study screens and summarizes
the key influencing factors of coal production costs
based on the internal lean market management
mechanism of coal enterprises, establishes the
PCA-SSA-SVR cost forecasting model, and applies
and verifies the model. Finally, the following three
conclusions are drawn:
(1) Compared with the traditional method of
distributing the cost of machinery and equipment
according to the standard, the internal lean
market-oriented management mechanism
implements the lean improvement system within the
enterprise, introduces a market-oriented mechanism,
and formulates labor quotas, which is more
conducive to the realization of fine-grained
enterprise costs management.
(2) By analyzing and summarizing the
interrelationship and change law between coal
production cost and various influencing factors, this
study comprehensively establishes the key factor
indicators that affect coal production cost from the
aspects of environment, management level, and
marketization quota, so as to ensure that coal
production cost Scientific Validity of Predictions.
(3) The results of the model application test show
that: based on the PCA-SSA-SVR model, the
efficient and accurate prediction of production costs
can be realized, which can provide a basis for coal
enterprises and other fields to formulate labor quotas
and cost control plans, and has certain promotion
and application for coal enterprises value.
