A payment bill query request initiated by a user through a third-party payment platform is obtained at a payment platform server. Whether a payment institution has generated a payment bill for the user is determined based on the payment bill query request, where the payment institution does not provide the third-party payment platform with bill generation information. If so, user information associated with the user is obtained by the payment platform server and based on the payment bill. Whether information for notification that the payment institution has generated the payment bill for the user has been pushed to the region that the user belongs to is determined. If not, the information for notification that the payment institution has generated a payment bill is pushed to each user associated with the third-party payment platform within the region that the user belongs to through an account of the third-party payment platform.

This document describes impact networks that enable stakeholders to measure and take actions to adjust the impact of changes to products and services. In one aspect, a method includes receiving a stakeholder impact graph defining stakeholders. Each stakeholder is a node that is connected to at least one other stakeholder by an impact relationship edge. Data defining a first design perturbation in one or more design properties for a product or service of a first stakeholder is received from the first stakeholder. A determination is made, for one or more second stakeholders of the stakeholders connected to the first stakeholder by a respective impact relationship edge, a respective impact on the second stakeholder caused by the first design perturbation. Data defining a remediation perturbation that adjusts the respective impact of the first deign perturbation on the one or more second stakeholders is received.

An enhanced prediction model utilizing product life cycle segmentation and historic prediction data for generating more accurate future failure rates. Input data is segmented into groups based on failure modes of a corresponding life cycle. A prediction model such as Weibull analysis is implemented for each segmented group. Historical prediction data is also segmented into groups. Prediction parameters for each group of segmented historical prediction data are compared with one another and the comparisons are then used to adjust the prediction parameters generated from the segmented groups of input data. Updated parameters for the input data are then output thereby generating a new future failure rate.

Systems and methods include initializing a trainees population (TP), calculating an objective function (OF) of the TP to identify a trainer. A teaching pool is created using variables of each trainee and the identified trainer, and unique variables are added to obtain an updated teaching pool (UTP), a search is performed in parallel on UTPs to obtain ‘m’ subset of variables and OFs. OFs of ‘m’ subset are compared with OFs of the trainee's and variables of a first trainee in each thread are updated accordingly. In parallel, an updated learning pool (ULP) is created for selected trainee and the trainees, by adding unique variables to obtain ‘n’ subset which are compared with objective functions of selected trainee and the trainees and variables of a second trainee are updated accordingly. These steps are iteratively performed to obtain an optimal subset of variables that is selected for teaching and learning phase.
