在多通道批处理系统中，作业的运行除了考虑作业之间的优先关系之外，还必须考虑系统能否为其所需的资源分配资源。因为在多通道批处理系统中同时有不只一道作业在CPU中运行，这样就会导致某个作业需要的资源正在被另一个作业占用，这样就会导致无法分配资源的作业进入等待状态，直到该资源被其它作业释放后才能重新激活。-Batch processing in multi-channel system, jobs run in addition to considering the precedence relations between operations, but also must consider the resources required for the system can allocate resources. Because in the multi-channel system at the same batch have more than one job running in the CPU, which would lead to a job required resources are occupied by another job, this will result in the allocation of resources can not work into the waiting state until the resources are released before other work re-activation.
