Problems solved by technology
[0004] It can be seen that most of the current research on reducing energy consumption in the manufacturing process focuses on the single goal of minimizing total energy consumption, without considering the conflict of interest between the manufacturing enterprise and the manufacturing system, that is, the conflict between energy consumption and workload balancing , such a manufacturing enterprise that is prone to monopoly cannot balance the workload of different manufacturing enterprises, which is not conducive to the healthy development of the manufacturing system

The invention discloses a flexible multi-task scheduling method in a manufacturing system. The time limit and quality limit of tasks are used as constraints, and the goal of minimizing total energy consumption and work load balance is established to establish a dual-objective optimization model. In stages, the service allocation vector is first iterated, and then the subtask sequence vector is generated and iteratively processed. Finally, the service allocation vector and the subtask sequence vector are processed, and the service allocation is considered in the search space that has been reduced by the first two stages. and subtask order to trade off total energy consumption and workload balancing under the constraints of quality and completion time. The invention has better performance when solving the multi-task scheduling problem considering energy consumption and intermediate buffer.
Description
technical field [0001] The application belongs to the technical field of flexible multi-task scheduling in manufacturing systems, and in particular relates to a flexible multi-task scheduling method in manufacturing systems. Background technique [0002] The flexible multi-task scheduling problem in manufacturing systems has been extensively studied in recent years. Traditional multi-task scheduling problems often optimize the quality of service (QoS) from the perspective of customers, such as time, cost, and reputation. However, when the optimization target is limited to the interests of customers, different tasks may be assigned to the same manufacturing service, resulting in idle resources and reducing resource utilization efficiency. [0003] The data show that manufacturing is the main sector of global energy consumption, and reducing energy consumption is a necessary condition for the manufacturing system to achieve green manufacturing. People have realized the importa...
