[0060] With the development of Internet and network technologies, various Web services have emerged. Web services include services based on programmable web pages. The XML standard can be used to describe, publish, discover, coordinate, and configure Web services to form business processes.

[0061] Business processes can comprise a series of interconnected, structured activities or tasks, which may include a specific web service provided by at least one customer. How to conduct stability assessments for business processes consisting of multiple web services is a pressing issue that needs to be addressed.

[0062] Static simulation is commonly used in related technologies to assess the stability of business processes. In static business process simulation, a set of functionally similar atomic services that can meet business requirements can be selected using QoS (Quality of Service) selection algorithms, and simulation is performed according to the given specific business process sequence.

[0063] However, many business development processes currently utilize distributed frameworks, and as business processes become increasingly complex, interactions between different applications may exist within a single business line. Due to the distributed nature of web services and network volatility, the instability of web services can pose risks to the entire business process.

[0064] In realizing the concept disclosed herein, the inventors discovered at least the following problems in the related technologies: the application scope of business process simulation is limited, and its stability and accuracy are low.

[0065] To at least partially address the technical problems existing in related technologies, this disclosure provides a business process simulation method, apparatus, electronic device, and readable storage medium, which can be applied to the fields of network technology and finance. The business process simulation method includes: acquiring service information of multiple services associated with a target business process and the relationships between these services; determining service information of replacement services for each of the multiple services based on the service name, start time, and execution failure probability information in the service information of each service; and simulating the target business process based on the service information of each service, the service information of the replacement services, and the relationships between the services to obtain the simulation result of the target business process, so as to determine whether to execute the target business process based on the simulation result.

[0066] It should be noted that the business process simulation method and apparatus provided in this disclosure can be used in the fields of network technology and finance, such as for business process simulation in banking. The business process simulation method and apparatus provided in this disclosure can also be used in any field other than network technology and finance, such as for web application development. The application fields of the business process simulation method and apparatus provided in this disclosure are not limited.

[0067] Figure 1 The illustration schematically depicts a system architecture to which a business process simulation method can be applied according to embodiments of this disclosure. It should be noted that... Figure 1 The examples shown are merely examples of system architectures that can be applied to the embodiments of this disclosure, in order to help those skilled in the art understand the technical content of this disclosure, but do not mean that the embodiments of this disclosure cannot be used in other devices, systems, environments or scenarios.

[0068] like Figure 1 As shown, the system architecture 100 according to this embodiment may include terminal devices 101, 102, and 103, a network 104, and a server 105. The network 104 serves as a medium for providing a communication link between the terminal devices 101, 102, and 103 and the server 105. The network 104 may include various connection types, such as wired and / or wireless communication links, etc.

[0069] Users can use terminal devices 101, 102, and 103 to interact with server 105 via network 104 to receive or send messages, etc. Various communication client applications can be installed on terminal devices 101, 102, and 103, such as shopping applications, web browser applications, search applications, instant messaging tools, email clients, and / or social platform software, etc. (for example only).

[0070] Terminal devices 101, 102, and 103 can be various electronic devices with displays and web browsing capabilities, including but not limited to smartphones, tablets, laptops, and desktop computers.

[0071] Server 105 can be a server that provides various services, such as a backend management server that supports websites browsed by users using terminal devices 101, 102, and 103 (for example only). The backend management server can analyze and process data such as received user requests, and feed back the processing results (such as web pages, information, or data obtained or generated according to user requests) to the terminal devices.

[0072] It should be noted that the business process simulation method provided in this embodiment can generally be executed by server 105. Correspondingly, the business process simulation device provided in this embodiment can generally be located in server 105. The business process simulation method provided in this embodiment can also be executed by a server or server cluster that is different from server 105 and capable of communicating with terminal devices 101, 102, 103 and / or server 105. Correspondingly, the business process simulation device provided in this embodiment can also be located in a server or server cluster that is different from server 105 and capable of communicating with terminal devices 101, 102, 103 and / or server 105. Alternatively, the business process simulation method provided in this embodiment can also be executed by terminal devices 101, 102, or 103, or by other terminal devices different from terminal devices 101, 102, or 103. Accordingly, the business process simulation device provided in this embodiment of the present disclosure may also be set in terminal device 101, 102, or 103, or in other terminal devices different from terminal device 101, 102, or 103.

[0073] It should be understood that Figure 1 The number of terminal devices, networks, and servers shown is merely illustrative. Depending on implementation needs, any number of terminal devices, networks, and servers can be included.

[0074] Figure 2 A flowchart illustrating a business process simulation method according to an embodiment of the present disclosure is shown schematically.

[0075] like Figure 2 As shown, the business process simulation method includes operations S210 to S230.

[0076] In operation S210, service information of each of the multiple services associated with the target business process and the relationships between the multiple services are obtained.

[0077] In operation S220, based on the service name, start time, and failure probability information of each of the multiple services, the service information of the replacement service for each of the multiple services is determined.

[0078] In operation S230, the target business process is simulated based on the service information of each of the multiple services, the service information of the replacement services of each of the multiple services, and the relationship between the multiple services. The simulation result of the target business process is obtained so as to determine whether to execute the target business process.

[0079] According to embodiments of this disclosure, the target business process may include a business process to be simulated. This target business process may include multiple services. By simulating the target business process, the execution of the target business process can be determined based on the simulation results, thereby achieving the design of the target business process.

[0080] According to embodiments of this disclosure, multiple services associated with a target business process can also be invoked by other business processes. These multiple services may include, for example, atomic services. An atom is a basic service unit that constitutes an application and is also the smallest unit that the operating system can manage and allocate permissions to.

[0081] According to embodiments of this disclosure, the association between multiple services may include, for example, the name of a service that has a prerequisite relationship with a certain service. For example, if a target business process can sequentially call services A, B, C, and D, then service C has a prerequisite relationship with service D, service B has a prerequisite relationship with service C, and service A has a prerequisite relationship with service B.

[0082] According to embodiments of this disclosure, the execution failure probability information may include a probability distribution function of errors occurring during service execution. The execution failure probability information can be used to characterize the probability of successful service call, the relationship between the time point of service call error and probability, etc.

[0083] According to embodiments of this disclosure, the alternative services for each of the multiple services may include a backup service to be switched in case a call to a certain service fails. For example, a target business process may sequentially call services A, B, C, and D. If a call to service B fails, the alternative service B' can be switched to. In this case, the target business process may sequentially call services A, B', C, and D.

[0084] According to embodiments of this disclosure, the simulation status of the target business process can be determined based on the simulation results, and further, it can be determined whether to execute the target business process.

[0085] According to embodiments of this disclosure, a target business process is simulated based on the service information of each of the multiple services, the service information of their respective replacement services, and the relationships between the multiple services, thereby obtaining the simulation result of the target business process. By incorporating execution failure probability information, this technique allows for the simulation of switching to a replacement service in the event of a service call failure, and the simulation result of the target business process under these circumstances is obtained. This enhances simulation capabilities and improves the versatility, stability, and accuracy of business process simulation.

[0086] The following is for reference. Figures 3-6 In conjunction with specific embodiments, Figure 2 The method shown will be further explained.

[0087] According to embodiments of this disclosure, the business process simulation method may further include the following operations.

[0088] In response to receiving a simulation request, multiple services in the target business process associated with the simulation request are identified based on the simulation request.

[0089] According to embodiments of this disclosure, a simulation request can be a request message sent by a user to a server through a client. The simulation request may include business simulation information of the target business process to be simulated. Based on the simulation request, a service pool that the target business process may call during the simulation can be established. The service pool S can be represented as S = {S1, S2, S3, ...}, where S1, S2, S3, etc., can represent multiple services in the target business process.

[0090] Figure 3 A flowchart illustrating a method for obtaining simulation results of a target business process according to an embodiment of the present disclosure is shown.

[0091] like Figure 3 As shown, operation S230 may include operations S331 to S332.

[0092] In operation S331, a business process simulation model is established based on the service information of each of the multiple services, the service information of the replacement services of each of the multiple services, and the relationship between the multiple services.

[0093] When operating S332, the target business process is simulated based on the business process simulation model to obtain the simulation results of the target business process.

[0094] According to embodiments of this disclosure, the service information of each of the multiple services further includes execution duration information and number of calls, and the service information of the replacement service of each of the multiple services includes the name of the replacement service.

[0095] According to embodiments of this disclosure, operation S331 may include the following operations.

[0096] A business process simulation model is established based on service name, start time, execution duration, failure probability, number of calls, replacement service name, and the relationships between multiple services.

[0097] According to the embodiments of this disclosure, multiple services such as service S1, service S2, and service S3 in service pool S can be modeled, and the business process simulation model can be used as shown in the following formula (1).

[0098] Serwce={StartTime,ExeTime,SuccessProbablityFuc,PreService,ChangeService,RetryTimes}(1)

[0099] Among them, StartTime represents the start time of the service execution, ExeTime represents the execution duration of the service, SuccessProbablityFuc represents the failure probability of the service during execution, PreService represents the name of the service that has a preceding relationship with this service, ChangeService represents the name of the replacement service of this service, RetryTimes represents the number of times the service is called, and PreService and ChangeService both belong to service pool S.

[0100] According to embodiments of this disclosure, operation S332 may include the following operations.

[0101] Based on the relationships between multiple services and their respective start times, these services are sequentially identified as target services. A business process simulation model is used to simulate the target services, obtaining their execution duration information. Based on this execution duration information, the simulation result of the target business process is determined, including the execution duration information of the target business process.

[0102] According to embodiments of this disclosure, before starting the simulation of the target business process, the service to be executed in the current time slice can be selected based on the relationships between multiple services and the start times of each service.

[0103] For example, if the target business process can call services A, B, C and D in sequence, with the start execution time of service A being T1, service B being T2, service C being T3 and service D being T4, and the current time slice being T0, and 0 < T1 < T2 < T0 < T3 < T4, then service B can be identified as the target service.

[0104] According to embodiments of this disclosure, the execution duration information of each of the multiple services can be determined sequentially, and the execution duration information of the target business process can be determined based on the execution duration information of each service.

[0105] According to embodiments of this disclosure, a business process simulation model is established based on the service information of each of the multiple services, the service information of their respective replacement services, and the relationships between the multiple services. The target business process is then simulated based on this simulation model to obtain the simulation results. Through these technical means, multiple services associated with a target business process can be modeled and simulated, expanding the application scope of business process simulation and improving its efficiency.

[0106] Figure 4 A flowchart illustrating a method for determining service information of a replacement service according to an embodiment of the present disclosure is shown.

[0107] Figure 5 The illustration shows an example schematic diagram of a business process simulation method according to an embodiment of the present disclosure.

[0108] like Figure 4 As shown, operation S220 may include operations S421 to S424.

[0109] In operation S421, the execution status of the target service is determined based on the start time of the target service and the failure probability information of the target service.

[0110] In operation S422, if the execution status of the target service indicates that the target service has failed, the execution duration information of the target service is determined.

[0111] In operation S423, if the number of times the target service is repeatedly called reaches the target service's call limit, the call duration information of the target service and the replacement service name of the target service are determined.

[0112] In operation S424, based on the name of the replacement service for the target service, the switching duration information and the execution duration information of the replacement service for the target service are determined.

[0113] According to embodiments of this disclosure, the target service information includes the target service name, the start time of the target service, the execution failure probability information of the target service, and the number of times the target service is called.

[0114] According to embodiments of this disclosure, the execution status of a target service can be used to characterize whether the target service was executed successfully. If the execution status of a target service indicates that the target service was executed successfully, the next target service can be determined.

[0115] According to embodiments of this disclosure, if the execution status of the target service indicates that the target service has failed, the target service can be invoked again. If the number of repeated invocations of the target service reaches the designated invocation limit for the target service, a replacement service for the target service can be determined.

[0116] According to embodiments of this disclosure, operation S332 may further include the following operations.

[0117] The execution duration information of the target service is determined based on the execution duration information of the target service, the call duration information of the target service, the switching duration information of the target service's replacement service, and the execution duration information of the target service's replacement service.

[0118] According to embodiments of this disclosure, a target service may correspond to multiple alternative services. Multiple alternative services can be sorted according to the failure probability information of the alternative services. In the event of a failure in calling the target service, an alternative service with a lower failure probability and higher stability is selected first.

[0119] For example, the target business process may call services A, B, C, and D sequentially. Based on the failure probability information of the replacement services, these services can be ordered as follows: replacement services for service A include A1, A2, and A3. If service A fails, service A1 can be called first. If service A1 fails, service A2 can be called next. If service A2 fails, service A3 can be called next. If service A3 succeeds, service B can then be called.

[0120] According to the embodiments of this disclosure, the specific order of calling the replacement service can be flexibly set by those skilled in the art based on the actual application situation. The embodiments of this disclosure do not limit the specific order of calling the replacement service.

[0121] According to embodiments of this disclosure, operation S230 may further include the following operations.

[0122] If the execution time of the target business process is less than or equal to a preset threshold, the target business process is executed.

[0123] like Figure 5 As shown, if the execution status of the target service indicates that the target service has failed, the execution duration information 501 of the target service can be determined. If the number of repeated calls to the target service reaches the target service's call limit, the call duration information 502 of the target service and the name of the alternative service can be determined. Based on the name of the alternative service, the switching duration information 503 and the execution duration information 504 of the alternative service can be determined.

[0124] According to the embodiments of this disclosure, pt can be used to represent the execution duration information 501 of the target service, tt can be used to represent the call duration information 502 of the target service, ST can be used to represent the switching duration information 503 of the replacement service of the target service, and at can be used to represent the execution duration information 504 of the replacement service of the target service. Then, the execution duration information WT1 of the target service can be represented by the following formula (2).

[0125] WT1=pt+tt+ST+at (2)

[0126] According to embodiments of this disclosure, multiple services can be sequentially identified as target services, each target service can be simulated to obtain execution time information for each target service, and the execution time information WT of the target service can be determined based on the execution time information WT1, WT2, WT3, etc. of each target service.

[0127] According to embodiments of this disclosure, the decision to execute a target business process can be determined based on the numerical relationship between the execution duration information (WT) of the target service and a preset threshold. If the execution duration information of the target business process is less than or equal to the preset threshold, it indicates that the target business process simulation was successful and the target business process can be executed. If the execution duration information of the target business process is greater than the preset threshold, it indicates that the target business process poses a risk and can be redesigned.

[0128] According to the embodiments of this disclosure, the preset threshold can be flexibly set by those skilled in the art based on the actual application situation, and the embodiments of this disclosure do not limit the preset threshold.

[0129] According to embodiments of this disclosure, the execution duration information WT1, WT2, WT3, etc. of each target service can be summarized and displayed.

[0130] Figure 6 An example schematic diagram illustrating how execution failure probability information changes over time according to an embodiment of the present disclosure.

[0131] According to embodiments of this disclosure, during execution, the service may perform different actions, and different actions may result in different probabilities of failure.

[0132] like Figure 6 As shown, at time t1, the service performed a relatively safe action, so the failure probability P1 was low. At time t2, the service performed a higher-risk action, so the failure probability P2 was high.

[0133] According to embodiments of this disclosure, since some services may be unreachable at the start of the call, the failure probability P3 is relatively high at time t=0. At time t3, the service call ends, and therefore the failure probability is 0.

[0134] According to embodiments of this disclosure, operation S421 may include the following operations.

[0135] Based on the start time and failure probability information of the target service, a random number within a preset range is generated. The execution status of the target service is then determined based on the random number.

[0136] According to embodiments of this disclosure, in each simulation time slice, random numbers within a preset range can be generated based on the start execution time of the target service and the execution failure probability information of the target service, in order to simulate the situation where the system may fail to execute in a real environment.

[0137] According to the embodiments of this disclosure, the preset range can be flexibly set by those skilled in the art based on the actual application situation, and the embodiments of this disclosure do not limit the preset range.

[0138] According to embodiments of this disclosure, after simulation, simulation information of the business process can be recorded, such as whether the business process has been completed, whether the execution has timed out, and the execution status of each service. Since introducing execution failure probability information usually introduces many uncertainties into a single simulation, multiple simulations can be performed, making the simulation results obtained from multiple simulations closer to the actual scenario.

[0139] According to embodiments of this disclosure, the execution duration information of the target service is determined based on the execution duration information of the target service, the call duration information of the target service, the switching duration information of the replacement service of the target service, and the execution duration information of the replacement service of the target service. This facilitates the subsequent determination of the simulation results of the target business process. By introducing execution failure probability information, the probability of a service successfully being called and the relationship between the time point of error and probability can be simulated using probabilistic methods. Therefore, it is possible to simulate the simulation process of switching to a replacement service in the event of a service call failure, thereby expanding the application scope of business process simulation and improving its stability and accuracy.
