每个用来标识作业的作业控制快JCB用结构来描述，包括以下字段：

（1）作业标识数ID

（2）作业运行所需要时间requesttime

（3）作业实际运行时间runtime

（4）作业优先权priority，并规定优先权越大的作业，其优先权越高

（5）作业紧迫程度quick，并规定紧迫程度越高的作业，其数值越大

注：以上字段并非每种作业调度算法都使用，仅仅出于方便编-Each operation used to identify the operational control of fast JCB used to describe the structure, which includes the following fields: (1) operating identification number ID (2) to run the operation will take time requesttime (3) operating the actual running time runtime (4) operating priority the right of priority, and provides for greater priority to the operation, the higher its priority (5) the urgency of operation quick, and provides a higher level of urgency of the operation, the greater its value Note: The above is not a field for each job scheduling algorithms are use, only made for convenience
