METAFORA是一个对矿山装载机-汽车作业系统进行战略决策和评估的模拟模型。METAFORA已被用来评估位于瑞典北部的布利登矿业（BoidenMineral）公司艾蒂克（Aitik）矿的运输系统，该矿是欧洲最大的露天矿之一，年产铜矿石1500万t。模拟得到的班矿石和废石装车数与矿山实际的装车数非常一致．艾蒂克矿电铲／汽车系统使用METAFORA模型中的调车准则进行模拟，以评估其它调度控制策略。结果表明，增大汽车的准则与固定配车准则所取得的总产量（矿石＋废石）大体相同，但矿石产量低7％；增大电铲准则获得的产量最低．METAFORA模型还用于设计废石运输路线的替代方案。本文表明，应用METAFORA这样的软件，可使电铲／汽车系统设计与评估工作的时间、工作量和成本大量降低。
METAFORA is a simulation model for strategic decisions and assessments of mine loader-car operating systems. METAFORA has been used to evaluate the transport system of Boit Minerals’ Aitik mine, one of Europe’s largest open pit mines, with an annual output of 15 million tonnes of copper ores, located in northern Sweden. The number of class ore and waste stone loading obtained from the simulation is very consistent with the actual number loaded in the mine. The Idit Mining Shovel / Vehicle System uses shunting guidelines in the METAFORA model to simulate other scheduling control strategies. The results show that the criteria for increasing the car are roughly the same as those for the fixed car code (ore + waste rock), but the output of ore is 7% lower; the increase of the shovel guideline yields the lowest output. The METAFORA model is also used as an alternative to designing waste rock transportation routes. This paper shows that using METAFORA software can dramatically reduce the time, effort, and cost of designing and evaluating shovels / automotive systems.
