In the field of manufacturing, complex products with a tree structure often naturally exhibit asymmetric characteristics due to uniqueness their constituent elements and hierarchical relationships. production scheduling such small-batch multi-variety products, influence process constraints, many pieces equipment will be idle for long time in process. This increases makespan reduces utilization rate equipment. Aiming at improving this situation, resource cooperative algorithm is proposed...

In the process of integrated scheduling multi-variety and small-batch complex products, structure attribute characteristics are often ignored, which affects overall effect. Aiming at solving this problem, a heuristic algorithm (HIS-IDA) based on improved Dijkstra is proposed. The takes processing time itself as path value preceding following adjacent processes. Firstly, prioritized sequence with long longitudinal paths realized “longitudinal optimization” scheduling. Secondly, layer priority...

Hyperledger is considered to be the most mature consortium chain technology. Compared with other blockchain technologies, focuses on application development of enterprise-level standards. Due its unique permission management, fine-grained access control, pluggable consensus algorithm and higher transaction performance, has been increasingly used in hospital information systems. Although there are more applications field health care, currently no research comprehensively classify compare...

In the research and practice of integrated scheduling problems, tree structure complex products usually presents an asymmetric form. This asymmetry is mainly reflected in hierarchical relationship between various components product, degree dependence, sequence production processes. Existing studies often neglect that leaf nodes with lowest layer priority can be scheduled at any moment, leading to underutilization parallelism potential under symmetric structures exacerbation critical path...

Aiming at the problem of current flexible integrated scheduling, most research shortens total processing time products and ignores loss equipment in processing, which affects scheduling ability equipment; this context, a algorithm considering periodic maintenance (FIS-PM) is proposed. The flexibly mobilizes sequence selected equipment, uniformly maintains all certain time. First, ISA-PM adopts strategy combination layer priority, short-time, priority to schedule operations. Then, based on...

For the existing multi-product integrated scheduling algorithm considering delivery date, inability to fully consider processing order of multiple products and potential conflicts in process causes problems such as equipment resource competition during products, ultimately resulting extension date failure deliver on time. Aiming at this problem, a dynamic with tight (ISA-TDD) is proposed. Firstly, initial scheme established according strategy ‘device priority + short time layer priority’....
