Maintenance management for transportation process in quarry industry

The purpose of this paper is to enhance the capability in managing the maintenance of the transportation process from a quarry to a crushing plant, measured by the availability value and the process capability value.

The maintenance management plan consists of plans for three levels of management: strategy, tactical and operational maintenance plans. The Deming cycle is a continuous improvement tool use for controlling and monitoring activities of the plans. There are three Deming cycles according to these plans, the first of which involves the improvement of machine performance and investment evaluation. The second involves the improvement of plans, schedule, and activities of preventive maintenance including autonomous maintenance. The third is for human resource development on maintenance works. Moreover, the feedback of a prior round of each cycle comes early to detect abnormalities that provide better capability in maintenance.

Three Deming cycles can use for enhancing the maintenance management. The parameters are availability (A) of machines and the capability process (Cpk) of the transportation process. The results of this research state that the availability value of machines increases to 80-92 percent while the process capability value increases to 0.56.

The maintenance management, especially strategic plan, tactical plan and operational plan via the Deming cycle, can be implemented in other medium-sized industries with limited technology and personnel. It was found that the implementation of the plans has continued to progress with the Deming cycle.

This paper proposes how to successfully implement the maintenance management for medium-sized industries with limited technology and personnel. The maintenance management of three levels is carried out simultaneously by using the Deming cycle. This work has proven to be successful which can be expressed in the availability and the capability process values.
