Randomization methods for healthcare scheduling optimization using perioperative stages. Poor scheduling of surgical appointments and procedures in operating rooms can lead to unnecessary downtime, and therefore loss of efficiency. The randomization methods include various probability models, Monte Carlo simulations, and stochastic optimization is used to optimize procedure scheduling in operating rooms. The optimized schedule may be based on estimated procedure duration, estimated turn-around-time, estimated cancellation frequency, forecasted emergency operating room usage, estimated surgeon utilization, and hospital site configuration. A probabilistic machine learning model may be trained based on historic data and ongoing performance data to automate the optimization process and increase accuracy based on up-to-date information and statistics.

The invention discloses a randomization method and a single secret leader election method, and belongs to the technical field of computer technology and information security. In order to solve the technical problems of unfair leader election and insufficient privacy caused by the fact that a decayed enemy can use a randomization process to interfere a system state, an approximately unique randomization component is constructed by using random factor commitment and hierarchical broadcast, and the component is used for driving a random shuffling process to generate a unique system state. A leader node is selected from the secret list based on the persistent random pointer and the system state is updated by the selected leader. According to the scheme, the consistency of randomization results and the approximate uniqueness of random factors can be realized, corruption opponents with any malicious behaviors can be resisted, and the fairness and privacy of election of a single secret leader can be ensured.

A method for managing a clinical trial for a drug includes determining a randomized patient list and a randomized kit list for the clinical trial, automatically validating the randomized lists, and configuring an RTSM system based on the validated lists. Validating the randomized patient list may include verifying that the patient list includes a balance or spread above a balance or spread threshold and verifying that the list has a randomness above a predetermined randomness threshold. Validating the randomized kit list may include verifying that the kit list has a randomness above a predetermined randomness threshold.

The application relates to the technical field of computers and discloses a high-performance randomization consistency method for uncertain environments, which comprises the following steps: step one, implanting a unified random seed for each process, which is used for ensuring that the random numbers generated by the processes in the same round are the same; step two, adding a process ID to each process for a proposal, and generating a local proposal value P; step three, generating a full permutation array id_seq of all process IDs in a unified sequence; step four, sending the local proposal value P to other processes through reliable broadcasting; step five, adding the proposal process ID to the set values together with the proposal value P; step six, entering stage 1 of the first round; and step seven, entering stage 2 of the first round.
