WebJob scheduling, also known as batch scheduling, is a process that allocates system resources to control the execution of unattended background programs. The scheduler decides which jobs to execute, at which time, and the central processing unit (CPU) resources needed to complete the job. WebFirst a random permutation of the job indices is generated. Then, in each step the next index i from this permutation is selected and all possibilities for inserting job ø(i) are …
WebThe joint scheduling of quay cranes (QCs), yard cranes (YCs), and yard trucks (YTs) is critical to achieving good overall performance for a container terminal. However, there are only a few such integrated studies. Especially, those who have taken the vessel stowage plan (VSP) into consideration are very rare. The VSP is a plan assigning each container …
