Abstract

This paper presents a Simulation Model linked to a Knowledge Based System (SM-KBS) built to support the scheduling for an underground mine. Both systems are designed by means of hierarchical, colored and temporal Petri Nets. Simulation Model simulates the operation of the production, reduction and transport levels. Knowledge Based System is activated by events produced in daily operations and yields the results of registered events and the actions taken to solve the problem, generating operation rules. The proposed model, parametrical and scalable, allows different types of mine operations and scenarios with the objective of obtaining data for decision-making. It helps to evaluate different policies against specific scenarios for programming the activities in the mine seeking to enlarge the equipment productivity. In addition, the model allows the feasibility assessment of the Daily Master Plan based on the input data of the simulation model.
