When prior art carries out bullet train exploitation, do not carry out standardization constraint to performance history, there is task duplication exploitation phenomenon, development process is complicated, not easy.The embodiment of the present invention by the Work flow model of abstract train performance history, building process meta-model, so as follow-up carry out bullet train exploitation time, can Kernel-based methods meta-model, obtain the actual development process of vehicle.So, just can optimize train performance history, avoid in train performance history, overlapping development phenomenon, contribute to improving development efficiency, effectively save the resource such as human and material resources and financial resources.
The embodiment of the present invention, when building process meta-model, relates to following two aspect data:
(1) process metamessage
It should be noted that, the process metamessage in the embodiment of the present invention refers to the information related in vehicle development process, particularly, at least can comprise project set, set of tasks and active set.
In the embodiment of the present invention, vehicle development process is defined by project, and project comprises a series of task, and task is realized by the activity with certain logical relation.That is, in vehicle development process, project, task and activity are the staples of formation process, and vehicle development process abstractly can be divided into three levels: item layer, task layer, mobile layer.
In the embodiment of the present invention, and project (English: Project) to describe by seven tuples, particularly, Project=(PID, D, Cal, T, RT, R, M).Wherein, PID represents project label; D represents the descriptor of project, and descriptor can be project objective, item source etc.; Cal represents project calendar; T represents the task identification of at least one task that project is corresponding, namely the set of tasks after Project decomposition, T=(T1 can be expressed as, T2, Tn), generally, project can comprise several large tasks such as product demand, conceptual design, technical design, job design, scheduling and planning; RT represents the relation between at least one task that project is corresponding, can be expressed as RT=(rt1, rt2 ... rtn), the relation between task can for starting-starting, start-terminate, terminate-start, terminate-terminate; R represents corresponding the exploiting natural resources of project; M represents the technical indicator that project is corresponding.
In the embodiment of the present invention, (English: Task) to refer to that having of completing needed for project each stage one sets the goal, semantic complete and relatively independent behavior, task is basic composition and the operating unit of project to task.For example, task can be overall design task, General layout Plan evaluation etc.In the embodiment of the present invention, task describes by nine tuples, particularly, and Task=(TID, D, IPT, R, Cal, S, I, O, A).Wherein, TID represents task identification; D represents the descriptor of task; IPT represents the development teams that task is corresponding; R represents corresponding the exploiting natural resources of task; Cal represents task calendar; S represents task status, task status can for ready, perform, hang up, complete etc.; I represents the input information of task, input information can for task object (as required time of finishing the work, finish the work needed for the target that reaches etc.), resource, input parameter etc.; O represents task output information, and output information can be the output parameter of task operating result; A represents the activity mark of at least one activity that task is corresponding.
In the embodiment of the present invention, movable (English: Activity) to refer to the abstractdesription to an execution step in process.Activity describes by eight tuples, particularly, and Activity=(AID, D, Cal, Person, SC, EC, IND, OUD).Wherein, AID expression activity mark; D represents Activity Description information; Cal represents calendar of events; The execution team that Person expression activity is corresponding; SC expression activity beginning condition; EC represents activity end condition; IND expression activity input information; OUD expression activity output information.
As a kind of example, by the mode of typing, receive the process metamessage of outside designer's typing, specifically can be divided into project typing, task typing, activity typing.
(2) structure tree data
In the embodiment of the present invention, vehicle structure tree refers to the structure dendrogram describing the physical composition parts of a certain vehicle and the level of each building block.Vehicle structure tree data mainly comprise following two class data: a class is hierarchical data, expression be the hierarchical information of each building block in vehicle structure tree; One class is topological data, expression be mutual relationship in vehicle structure tree between the information of each building block and each building block.
In the embodiment of the present invention, vehicle structure tree data at least can comprise: at least one in level title, father node title, child node title, structure description information.
Vehicle structure tree data are kept in structure tree database, when needed, can read relevant vehicle structure tree data from structure tree database.
So, after procurement process metamessage and structure tree data, just can utilize the two building process meta-model, and be stored in Process Meta-Model database, to use in follow-up vehicle development process.In the embodiment of the present invention, Process Meta-Model can be understood as, be the Work flow model in order to define pedigree bullet train performance history and the abstract model defined, for describe comprise in performance history process content, annexation between process, implementation constrained input, etc.Introduced from above-mentioned, the mode of embodiment of the present invention building process meta-model is: utilize and represent each abstract process unit in pedigree bullet train performance history, connected, obtain the specific R&D process needed for train exploitation, i.e. Process Meta-Model by combination.
For example, Process Meta-Model can be expressed as Process={<Project>LEssT.LTssT .LTTasks><ActivitysGreatT.Gre aT.GT}, as a kind of example, Process Meta-Model can embody as follows:
