Description

Technical Field

[0001] The present invention relates to the technical field of project progress management, and in particular to an information-based project progress management system and method. Background Art

[0002] With the expansion of enterprise scale and the increase of project complexity, the traditional manual management model gradually reveals its limitations, such as information lag, poor communication, and difficult risk control. Therefore, the project progress monitoring system came into being and became an important tool for project management. In the process of project supervision, the combination of project progress management and testing process is a key process to ensure that the project is delivered on time and meets quality requirements. Therefore, how to effectively supervise the testing process in the process of progress supervision is particularly important, but the existing supervision system is often real-time analysis, and adjustments are made when problems arise in the testing process. It fails to analyze and judge from an overall macro perspective whether the project cycle increased by solving problems in the testing process will affect the overall progress. Summary of the invention

[0003] The purpose of the present invention is to provide an information-based project progress management system and method to solve the problems raised in the prior art.

[0004] To achieve the above object, the present invention provides the following technical solution: a project progress management method based on information technology, the method comprising the following specific steps:

[0005] Step S100: Obtain the project management process corresponding to each project name entered into the project progress management system, locate the link for implementing the test work in each project management process, and mark the next non-test link for implementing the test work as the initial inspection link; determine the corresponding project key node based on the initial inspection link of each project management process;

[0006] Step S200: extracting the project data required by the test work corresponding to the key nodes of the project before executing the test, and the project link corresponding to the project data as the pre-link, constructing a two-phase link chain of the link corresponding to the test work and the key nodes of the project based on the pre-link; evaluating the correlation influence coefficient on the test work when the link content in the two-phase link chain is changed;

[0007] Step S300: Based on the correlation influence coefficient and the critical deviation coefficient required for determining the key nodes of the project, a progress assessment value output model corresponding to each type of project link content change at each key node of the project is constructed;

[0008] Step S400: Monitor and match the historical project management process corresponding to the same real-time project name, monitor the predecessor project in execution, and perform similarity analysis when the content of the predecessor project changes, determine the progress assessment value output model of the content change of the corresponding type of project link and determine whether to issue an early warning.

[0009] Furthermore, determining the corresponding key nodes of the project based on the initial inspection phase of each project management process includes the following steps:

[0010] Step S110: extract all the project links that are associated before the initial inspection link in the same project management process as the first associated link, and the first associated link represents the source link corresponding to the project data required by the initial inspection link; obtain the number D1 of the first associated links recorded in each initial inspection link in each project management process, and calculate the average number D1 of associated links about the initial inspection link in the corresponding project association process 0 , D 0 =(1 / N)∑D 1 , where N represents the number of initial inspection links included in the same project management process;

[0011] Step S120: Eliminate the initial inspection link corresponding to the number of first associated links that is less than the average number of associated links in the corresponding project management process, and update the initial inspection link of the corresponding project management process to the first inspection link;

[0012] Step S130: extracting the same project management process whose historical records are marked as reasonable project progress and unreasonable project progress, analyzing the characteristic coefficients after comparing the project management processes corresponding to reasonable project progress and unreasonable project progress based on the same initial inspection link and the link cycle recorded in the link corresponding to the previous test implementation work in the same project management process, and outputting the initial inspection link included in the updated project management process as the second inspection link;

[0013] Step S140: Take the intersection of the link set formed by the first inspection link and the second inspection link to generate a first set, then take the union of the first set and the corresponding set of the second inspection link to generate the project key nodes of the project management process under the same project name. Therefore, the generation of the project key nodes is based on the characteristic coefficient as the time correlation basis, combined with the project links determined by the link correlation degree analysis, so that the management of the project progress from the time dimension is more comprehensive.

[0014] Furthermore, step S130 also includes the following specific steps:

[0015] Step S131: extract the project management process corresponding to the implementation period greater than the preset standard under the conditions of reasonable project progress and unreasonable project progress in the same initial inspection link as the target management process; extract the actual link implementation period T of the target management process recording the initial inspection link and the previous implementation test work link; use the formula:

[0016] k 1 =(y 1 -b 1 ) / x 1 ;x 1 =T x1 -T 01 ,y 1 =T y1 -T 02 ;

[0017] k 2 =(y 2 -b 2 ) / x 2 ;x 2 =T x2 -T 01 ,y 2 =T y2 -T 02 ;

[0018] Substitute several groups of the same target management process records (x 1 ,y 1 ) and (x 2 ,y 2 ), calculate the fluctuation coefficient k of the previous implementation test work link to the initial inspection link in the target management process under the condition of reasonable project progress 1 and the constant term b 1 , and the fluctuation coefficient k of the previous implementation test work link to the initial inspection link in the target management process when the project progress is unreasonable 2 and the constant term b 2 ; where T x1 It represents the actual implementation cycle of the previous test work link under the condition of reasonable project progress, T x2 It represents the actual implementation cycle of the previous test work link when the project progress is unreasonable. 01 It indicates that the target management process records the preset standard implementation cycle of the previous test work link; T y1 It represents the actual implementation cycle of the initial inspection phase under reasonable project progress, T y2 It indicates the actual implementation cycle of the initial inspection phase when the project schedule is unreasonable; T 02 It indicates the preset standard implementation cycle of the initial inspection phase of the target management process record;

[0019] The purpose of determining the target management process is to select the possible influencing processes that can reflect the implementation cycle fluctuations in the initial inspection phase in the project management processes in two situations, so as to further analyze the factors that can affect the inspection phase under different circumstances.

[0020] Analyzing the fluctuation coefficient of the previous test work link to the initial inspection link under the conditions of reasonable project progress and unreasonable project progress can effectively evaluate whether the initial inspection link is affected by the periodic changes of the test link; because only when there is an influence relationship between the two, the system can further predict the project progress before the key node, thereby improving the effectiveness and efficiency of progress monitoring;

[0021] Step S132: The fluctuation coefficient k corresponding to the same initial inspection link 1 and the volatility coefficient k 2 Perform difference calculation to obtain the characteristic coefficient k 0 , k 0 =|k 1 -k 2 |, set the characteristic coefficient threshold k 0 , extract k 0 Less than or equal to k 0 The corresponding initial inspection stage is the second inspection stage of the corresponding project management process.

[0022] Further, step S200 includes the following:

[0023] Step S210: obtaining the first associated link of the project key node record, taking the intersection of the set consisting of the preceding link and the first associated link to generate a second set, and generating a two-phase link chain based on the execution order of the project links in the second set according to the corresponding project management process;

[0024] Step S220: extract different project events of the same project management process under reasonable historical records of project progress. Project events refer to events corresponding to the increase in duration caused by content changes in the implementation duration of project links in the two-phase link chain; generate a function model T for each project management process to record the corresponding test work links of each type of project event x1 , T x1 =a 1 ×u 1 +a 2 ×u 2 +...+a m ×u m +ε, where u 1 、u 2 ,...,u m Indicates the increased project duration corresponding to the 1st, 2nd, ..., mth project links with content changes in the project event;

[0025] Substitute the duration data of several groups of project events recorded at different times for the corresponding duration of the same project link content change, and solve to obtain the reference coefficient a of the corresponding type of project event function model 1 、a 2 , ..., a m and the error term ε;

[0026] Step S230: Calculate the correlation influence coefficient t under the same type of project events, t=(T x1 -T 01 ) / T 01 ; where T x1 The function model outputs the actual link implementation cycle value for the project management process record corresponding to the project event.

[0027] Furthermore, step S300 includes the following specific processes:

[0028] Extract and calculate the project events corresponding to each correlation impact coefficient, and find the actual link implementation cycle T of the key nodes of the project in the project management process where the project event is located y1 , calculate the critical deviation coefficient r of the project event corresponding to the key node of the project, r=(T y1 -T 02 ) / T 02 ;

[0029] Based on the same type of project events, the progress assessment value output model Z corresponding to each key node of the project where each associated impact coefficient is located is constructed, Z=|t i -r i | max , where t i represents the correlation influence coefficient of the i-th category in the same category of project events, r i represents the critical deviation coefficient corresponding to the i-th type; |t i -r i | max It represents the maximum value of the difference between the associated impact coefficient and the critical deviation coefficient in the same type of project events, and the maximum value is used as the progress assessment value.

[0030] Further, step S400 includes the following:

[0031] Extract the predecessor projects with content changes in real-time monitoring as key predecessor projects, find the project events with 100% similarity with the names of the key predecessor projects when the project links are changed in the historical records as key events, substitute the increased project duration corresponding to the key predecessor projects into the function model of the key event records, obtain the estimated link implementation cycle value output by the function model, and calculate the estimated correlation impact coefficient;

[0032] Based on the estimated correlation influence coefficient, the output model of the progress assessment value of the key event record and the critical deviation coefficient corresponding to the output value are extracted to calculate the estimated progress assessment value. The estimated progress assessment value is calculated by taking the absolute value of the difference between the estimated correlation influence coefficient and the critical deviation coefficient corresponding to the output value. If the estimated progress assessment value is greater than the output value of the output model of the progress assessment value of the key event record, a warning signal is transmitted. If the estimated progress assessment value is less than or equal to the output value of the output model of the progress assessment value of the key event record, monitoring continues.

[0033] The transmission warning signal indicates that the increase in the duration of the project link caused by the change in the content of the current predecessor link may have an impact on the subsequent key links of the project, thereby causing a large deviation from the estimate of the overall project progress. An early warning is needed to remind project management staff to adjust the subsequent testing links and monitor the progress of key project nodes.

[0034] An information-based project progress management system, the system includes a project management process acquisition module, a project key node determination module, a correlation influence coefficient analysis module, a progress assessment value output model construction module and a pre-project monitoring and early warning module;

[0035] The project management process acquisition module is used to obtain the project management process corresponding to each project name entered into the project progress management system;

[0036] The project key node determination module is used to determine the corresponding project key nodes based on the initial inspection phase of each project management process;

[0037] The correlation impact coefficient analysis module is used to evaluate the correlation impact coefficient of the test work when the content of the link in the two-phase link chain is changed;

[0038] The progress assessment value output model construction module is used to construct a progress assessment value output model for each key node of each project corresponding to the content changes of each type of project link;

[0039] The pre-project monitoring and early warning module is used to determine the progress assessment value output model of the content change of the corresponding type of project link and determine whether to issue an early warning.

[0040] Further, the project key node determination module includes a first associated link analysis unit, a first inspection link update unit, a second inspection link determination unit and a project key node output unit;

[0041] The first associated link analysis unit is used to extract all project links that are associated before each initial inspection link in the same project management process as the first associated link;

[0042] The first inspection link updating unit is used to remove the initial inspection link corresponding to the number of first associated links less than the average number of associated links in the corresponding project management process, and update the initial inspection link of the corresponding project management process to the first inspection link;

[0043] The second inspection link determination unit is used to analyze the characteristic coefficients after comparing the corresponding project management processes of reasonable project progress and unreasonable project progress, and output the initial inspection link included in the updated project management process as the second inspection link;

[0051] Compared with the prior art, the present invention has the following beneficial effects:

[0073] A project progress management method based on information technology, the method includes the following specific steps:

[0074] Step S100: Obtain the project management process corresponding to each project name entered into the project progress management system, locate the link for implementing the test work in each project management process, and mark the next non-test link for implementing the test work as the initial inspection link; determine the corresponding project key node based on the initial inspection link of each project management process;

[0075] Step S200: extracting the project data required by the test work corresponding to the key nodes of the project before executing the test, and the project link corresponding to the project data as the pre-link, constructing a two-phase link chain of the link corresponding to the test work and the key nodes of the project based on the pre-link; evaluating the correlation influence coefficient on the test work when the link content in the two-phase link chain is changed;

[0078] Determining the corresponding key project nodes based on the initial inspection phase of each project management process includes the following steps:

[0079] Step S110: extract all the project links that are associated before the initial inspection link in the same project management process as the first associated link, and the first associated link represents the source link corresponding to the project data required by the initial inspection link; obtain the number D1 of the first associated links recorded in each initial inspection link in each project management process, and calculate the average number D1 of associated links about the initial inspection link in the corresponding project association process 0 , D 0 =(1 / N)∑D 1 , where N represents the number of initial inspection links included in the same project management process;

[0080] Step S120: Eliminate the initial inspection link corresponding to the number of first associated links that is less than the average number of associated links in the corresponding project management process, and update the initial inspection link of the corresponding project management process to the first inspection link;

[0081] Step S130: extracting the same project management process whose historical records are marked as reasonable project progress and unreasonable project progress, analyzing the characteristic coefficients after comparing the project management processes corresponding to reasonable project progress and unreasonable project progress based on the same initial inspection link and the link cycle recorded in the link corresponding to the previous test implementation work in the same project management process, and outputting the initial inspection link included in the updated project management process as the second inspection link;

[0082] Step S140: Take the intersection of the link set formed by the first inspection link and the second inspection link to generate a first set, then take the union of the first set and the corresponding set of the second inspection link to generate the project key nodes of the project management process under the same project name. Therefore, the generation of the project key nodes is based on the characteristic coefficient as the time correlation basis, combined with the project links determined by the link correlation degree analysis, so that the management of the project progress from the time dimension is more comprehensive.

[0083] Step S130 also includes the following specific steps:

[0084] Step S131: extract the project management process corresponding to the implementation period greater than the preset standard under the conditions of reasonable project progress and unreasonable project progress in the same initial inspection link as the target management process; extract the actual link implementation period T of the target management process recording the initial inspection link and the previous implementation test work link; use the formula:

[0085] k 1 =(y 1 -b 1 ) / x 1 ;x 1 =T x1 -T 01 ,y 1 =T y1 -T 02 ;

[0086] k 2 =(y 2 -b 2 ) / x 2 ;x 2 =T x2 -T 01 ,y 2 =T y2 -T 02 ;

[0087] Substitute several groups of the same target management process records (x 1 ,y 1 ) and (x 2 ,y 2 ), calculate the fluctuation coefficient k of the previous implementation test work link to the initial inspection link in the target management process under the condition of reasonable project progress 1 and the constant term b 1 , and the fluctuation coefficient k of the previous implementation test work link to the initial inspection link in the target management process when the project progress is unreasonable 2 and the constant term b 2 ; where T x1 It represents the actual implementation cycle of the previous test work link under the condition of reasonable project progress, T x2It represents the actual implementation cycle of the previous test work link when the project progress is unreasonable. 01 It indicates that the target management process records the preset standard implementation cycle of the previous test work link; T y1 It represents the actual implementation cycle of the initial inspection phase under reasonable project progress, T y2 It indicates the actual implementation cycle of the initial inspection phase when the project schedule is unreasonable; T 02 It indicates the preset standard implementation cycle of the initial inspection phase of the target management process record;

[0088] Reasonable project progress means that the length of the project cycle from the beginning of implementation to the end of the historical record is within the preset error range; conversely, if it exceeds the preset error range, the output is unreasonable project progress; determining the target management process is to select the possible influencing process that can reflect the implementation cycle fluctuations of the initial inspection stage in the project management process in two cases, so as to further analyze the factors that can affect the inspection stage under different circumstances.

[0089] Analyzing the fluctuation coefficient of the previous test work link to the initial inspection link under the conditions of reasonable project progress and unreasonable project progress can effectively evaluate whether the initial inspection link is affected by the periodic changes of the test link; because only when there is an influence relationship between the two, the system can further predict the project progress before the key node, thereby improving the effectiveness and efficiency of progress monitoring;

[0090] Step S132: The fluctuation coefficient k corresponding to the same initial inspection link 1 and the volatility coefficient k 2 Perform difference calculation to obtain the characteristic coefficient k 0 , k 0 =|k 1 -k 2 |, set the characteristic coefficient threshold k 0 , extract k 0 Less than or equal to k 0 The corresponding initial inspection stage is the second inspection stage of the corresponding project management process.

[0091] Step S200 includes the following:

[0092] Step S210: obtaining the first associated link of the project key node record, taking the intersection of the set consisting of the preceding link and the first associated link to generate a second set, and generating a two-phase link chain based on the execution order of the project links in the second set according to the corresponding project management process;

[0093] Step S220: Extract different project events of the same project management process under reasonable historical records of project progress. Project events refer to events corresponding to the increase in duration caused by changes in the implementation duration of project links in the two-phase link chain; if different, it means that the project links corresponding to the increase in duration are different; generate a function model T for each project management process to record the corresponding test work links of each type of project event x1 , T x1 =a 1 ×u 1 +a 2 ×u 2 +...+a m ×u m +ε, where u 1 、u 2 ,...,u m Indicates the increased project duration corresponding to the 1st, 2nd, ..., mth project links with content changes in the project event;

[0094] Substitute the duration data of several groups of project events recorded at different times for the corresponding duration of the same project link content change, and solve to obtain the reference coefficient a of the corresponding type of project event function model 1 、a 2 , ..., a m and the error term ε;

[0095] Step S230: Calculate the correlation influence coefficient t under the same type of project events, t=(T x1 -T 01 ) / T 01 ; where T x1 The function model outputs the actual link implementation cycle value for the project management process record corresponding to the project event.

[0096] As shown in the embodiment: there is a project management process: link 1 → link 2 → link 3 → link 4 → link 5 → link 6, where link 5 is a test link and link 6 is a key node of the project;

[0097] If the first associated link of the project key node record includes link 2 and link 4; the preceding link includes link 3 and link 4, then the second set is: link 2, link 3, link 4;

[0098] And the generated two-phase link chain is: link 2 → link 3 → link 4;

[0099] If the duration of recording link 2 of project event type a increases due to content changes, and two sets of data are recorded (u 1 `,T x1 `) and (u 1 ``,T x1 ``), u 1`≠u 1 ``, we can get the time relationship model of the impact of the change in link 2 on the test work link; and calculate the corresponding correlation impact coefficient t, and a corresponding correlation impact coefficient can be obtained for each group of data for the same project event type.

[0100] Step S300 includes the following specific processes:

[0101] Extract and calculate the project events corresponding to each correlation impact coefficient, and find the actual link implementation cycle T of the key nodes of the project in the project management process where the project event is located y1 , calculate the critical deviation coefficient r of the project event corresponding to the key node of the project, r=(T y1 -T 02 ) / T 02 ;

[0102] Based on the same type of project events, the progress assessment value output model Z corresponding to each key node of the project where each associated impact coefficient is located is constructed, Z=|t i -r i | max , where t i represents the correlation influence coefficient of the i-th category in the same category of project events, r i represents the critical deviation coefficient corresponding to the i-th type; |t i -r i | max It represents the maximum value of the difference between the associated impact coefficient and the critical deviation coefficient in the same type of project events, and the maximum value is used as the progress assessment value.

[0103] Step S400 includes the following:

[0104] Extract the pre-projects with content changes in real-time monitoring as key pre-projects, find the project events with 100% similarity to the key pre-project names when the project links in the historical records are changed as key events, substitute the increased project duration corresponding to the key pre-projects into the function model of the key event records, and obtain the estimated link implementation period value output by the function model and calculate the estimated correlation influence coefficient; the estimated link implementation period value and the calculated estimated correlation influence coefficient are calculated by steps S220-S230;

[0105] Based on the estimated correlation influence coefficient, the output model of the progress assessment value of the key event record and the critical deviation coefficient corresponding to the output value are extracted to calculate the estimated progress assessment value. The estimated progress assessment value is calculated by taking the absolute value of the difference between the estimated correlation influence coefficient and the critical deviation coefficient corresponding to the output value. If the estimated progress assessment value is greater than the output value of the output model of the progress assessment value of the key event record, a warning signal is transmitted. If the estimated progress assessment value is less than or equal to the output value of the output model of the progress assessment value of the key event record, monitoring continues.

[0106] The transmission warning signal indicates that the increase in the duration of the project link caused by the change in the content of the current predecessor link may have an impact on the subsequent key links of the project, thereby causing a large deviation from the estimate of the overall project progress. An early warning is needed to remind project management staff to adjust the subsequent testing links and monitor the progress of key project nodes.

[0107] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
