Vale's operations in Sudbury are among the largest on the planet, employing approximately 4,000 people. An underground copper/nickel mine located in Sudbury operates aggressively with an annual output of 100 million pounds of copper and 50 million pounds of nickel, in addition to other precious metals. Typically, the ore is blasted underground and transported by means of electrically powered trucks to a hoisting station whereby the ore is lifted to the surface. Failure of these trucks to be in an available state when needed poses a serious bottleneck to the flow of operation and consequently, production. Currently, there are a total of 6 trucks which are used generally-5 of which must be in operation at any time; and 1 undergoing repair. Maintenance personnel are concerned with the effectiveness of the current PM policies and would like to know the effect of current PM policy on the trucks failure patterns-hence availability. Furthermore, any improvements to the current PM policies which would effectively increase truck availability is much desired. The main objective of this project is to develop methodologies for 1) reliability analysis and reliability modeling of AC and DC haulage trucks, 2) reliability analysis and reliability modeling of major systems of AC and DC trucks, 3) downtime and availability analysis of AC and DC trucks, and 4) the prediction of future failures and downtime of the trucks.

淡水河谷在萨德伯里的业务是全球最大的业务之一，雇佣了大约4000名员工。位于萨德伯里的一座地下铜/镍矿积极运营，除了其他贵金属外，年产量为1亿磅铜和5000万磅镍。通常情况下，矿石被爆破到地下，然后通过电动卡车运输到起重站，在那里矿石被抬到地面。这些卡车在需要时不能处于可用状态，对作业流程造成严重的瓶颈，从而影响生产。目前，共有6辆通用卡车--其中5辆必须在任何时候运行；1辆正在维修。维护人员关心当前PM政策的有效性，并想知道 关于卡车故障模式的当前PM政策-因此可用。此外，对当前PM政策的任何改进都将有效地增加卡车的可用性。该项目的主要目标是开发一种方法，用于1)交直流运输车的可靠性分析和可靠性建模，2)交直流运输车主要系统的可靠性分析和可靠性建模，3)交直流运输车的停机时间和可用性分析，以及4)卡车未来故障和停机时间的预测。
