To provide a novel technology for planning renewal of existing pipelines within a renewal range.SOLUTION: An AI-based buried pipeline renewal planning system comprises an acquisition unit that obtains pipeline type information including pipeline renewal costs per pipeline type attribute, a renewal budget that is an annual budget for renewing existing pipelines within a renewal scope, and a renewal priority of pipelines, a pipeline type attribute determination unit that determines post-renewal pipeline type attributes for existing pipelines within the renewal scope, and a planning unit that formulates renewal plans for the existing pipelines within the renewal scope including renewal costs when the existing pipelines within the renewal scope are renewed to the post-renewal pipeline type attributes and renewal timing within the budget.SELECTED DRAWING: Figure 1

The application relates to the technical field of network security, and discloses a certificate adaptive degradation scheduling and renewal method and system based on an ACME renewal information protocol, which is used for solving the technical problems of low automation degree and poor renewal management effect of a certificate renewal method in the prior art. The method comprises the following steps: maintaining an independent scheduling state for each certificate; wherein the scheduling state at least comprises a next check time and a scheduling level; judging whether the check process of a target certificate is triggered according to the next check time; when the check process of the target certificate is triggered, corresponding processing strategies are executed based on the scheduling level of the target certificate; if the execution fails, the scheduling level of the target certificate is switched based on the error type at the time of failure, and the next check time is updated; if the execution succeeds, a renewal time is obtained according to the scheduling level at the time of successful execution; and the ACME certificate issuing process is triggered based on the renewal time to realize automatic renewal.

The invention provides a distributed lock renewal method, system, device and product. The distributed lock renewal method comprises the steps of obtaining historical renewal time consumption of task execution of a distributed lock; calculating the renewal time interval of the distributed lock by using the historical renewal time consumption, the basic time interval and the dynamic adjustment rule; and sending a renewal request to database equipment according to the renewal time interval obtained by calculation so as to complete renewal before the distributed lock expires.

The plan creation unit (21) creates an update plan indicating the update timing for each of multiple parts that make up the equipment, for each combination of multiple upper limit rates and multiple lower limit rates. The plan creation unit (21) sets each of the multiple parts as a target part and creates an update plan in which the update timing for the target part is set to a period that is equal to or less than a usage upper limit obtained by multiplying the lifespan of the target part by the upper limit rate for the target combination and is equal to or greater than a usage lower limit obtained by multiplying the lifespan of the target part by the lower limit rate for the target combination. The presentation unit (24) presents the created update plan for each combination.
