Algorithm Scala-并行生产订单计划

我被要求用Scala做一个算法来安排工厂生产计划。工厂运行到具有多个任务（与时间相关）的订单中，这些订单具有物理资源，可以由人力资源完成

第1部分几乎完成了（缺少正确的人力资源安排-重复：（），但第2部分更有趣。在快速概述第1部分后，将在此处进行解释：

第2部分-使用订单上的并行指令对此进行优化（订单可以同时运行，但其任务必须在没有并行命令的情况下运行-现在就是这样）。问题如下：

此里程碑尝试通过允许执行多个任务来最小化完整的生产时间 同时执行。特定产品的生产任务不能在 并行但是，对于两个或多个产品，相同顺序的任务可以并行放置 优化是按订单处理的。 在此里程碑中，生产计划的生成假设： 1） 产品按照输入文件规定的顺序生产； 2） 一次可以执行多个任务 3） 只有在有足够的物理资源的情况下，才能并行执行任务& 人力资源

你知道怎么做吗
