Description

Bulleted list based on item taxonomy tree

Technical field

The present invention relates to the project management development technique field of classification of the items, more particularly on item taxonomy tree and project The project management mechanism of list.

Background technology

Project management is the method for managing system using project as object, it by a provisional special flexible tissue, Expeditiously plan, tissue, guidance and control are carried out to project, to realize the dynamic management of project overall process and the synthesis of target Coordinate and optimize.Project is prevalent in the items of our human societies as a kind of disposable and unique social activities Among activity, it might even be possible to say it is that the existing various material and culture achievements of the mankind are realized by way of project, Because the relied on facility of existing various operations and condition are all initially to lean on project activity construction or exploitation.The mesh of project management Property to go to ensure to meet or surmount by carrying out project management activity project objective that project each side concerned face clearly proposes or Index and meet project each side concerned be not known as defined in potential demand and pursuit.The uniqueness of project management be project management not The production and operation management of in general enterprise is same as, government and unique management content also different from routine, is a kind of entirely different Management activity.The integration of project management be project management in must according to each key element of detailed programs or it is each specialty between Configuration relation carries out the management of integration, and can not carry out in isolation project it is each specialty or specialty manage independently.Project pipe The novelty of reason includes two layers of meaning：One refers to that project management is the pipe for innovating (innovation that project is included) Reason, secondly the management for referring to any one project is required for going by management innovation all without unalterable pattern and method Realize effective management for detailed programs.

The most important work of project management is the plan of project, scheduling is split and control, and wherein project scheduling splits conduct An important step in project management, reasonably dispatches and wherein critical effect is played to the quality of project management.At present The detachable property of task is effectively used in many project managements.On the one hand, because turn of the market, customer demand and technology become Some hot jobs of reason such as more have pending, it is necessary to call some resources urgent to perform these from being carrying out for task Task, the task in being currently executing can be so caused to suspend execution due to a lack of resource, until after hot job has performed It is further continued for performing current task；On the other hand, in order to maximize some valuable sources (such as some visual plants or human resources) Use value, realize the performance of enterprises maximize, it may be necessary to allocated in multiple projects, if task is detachable, Resource allocation has more flexibility during the project implementation, and resource is effectively used, and project can be completed in time.

System is implemented based on benefit caused by the bulleted list of item taxonomy tree：On the one hand it is to possess Project Manager's body Part people provide flexible, convenient operation interface, have the advantages that security it is good, it is easy to operate, realize it is easy；On the other hand The mechanism of item taxonomy tree and bulleted list is made full use of to improve production efficiency, quality and the continuity of work again, and can More flexible distribution task.

The content of the invention

In order to overcome the shortcomings of existing bulleted list, the present invention provides a kind of bulleted list based on item taxonomy tree, Automatically generate a pattern:Bulleted list carries out planning classification by item taxonomy tree：Prescribed time-limit, allocated items weight；All Sub-project is 2 layers of special construction, and classified catalogue+project data form is present；It can carry out automatically creating for 2 times in bulleted list specified Personnel and a large amount of sub-projects；Preview planning is carried out to project；Lateral comparison is carried out according to time shaft according to all participants, and And any increase and decrease can be carried out to personnel；Inside project planning multiple prime items selections, only prime item can be carried out to project Just start this project after the completion of mesh.It on the one hand can so reduce the integrated project program safety control of more sub-project compositions Complexity and difficulty, the mechanism on the other hand can be made full use of to be split after project receives again and send and wait all tear open Molecule project is completed after checking and accepting, then applies checking and accepting from fractionation person to the total publisher of project.

The technical solution adopted for the present invention to solve the technical problems is：The interest of user is different, its interest arest neighbors Answer what different thought proposed, therefore introduce item classification information, different interest arest neighbors is obtained for the different interest of user Recommended, so as to improve the recommendation quality of system.Algorithm enters scoring of the user to project first with item classification information Row classification, i.e., it is different for different interest, user group.Secondly under same project classification, calculate item similarity and obtain Project similar neighborhood, predict that it does not score using the scoring with the non-scoring item similarity highest project similar neighborhood of user The scoring of project.Then different interest is directed to, calculates the similar neighborhood of user in each class respectively, will be with target base phase Targeted customer is recommended like the interest of degree highest neighbor user.

The invention has the advantages that solve because the reasons such as turn of the market, customer demand and technology alteration are from It is due to a lack of resource and temporary come the task in being carrying out caused by the meeting that carries out an urgent task that some resources are called in the task of execution Stop performing；The use value of valuable source (such as some visual plants or human resources) is maximized, realizes that the performance of enterprises maximizes, Bulleted list based on item taxonomy tree, resource allocation has more flexibility during the project implementation, and resource is effectively made With project can be completed in time.

Embodiment

In Fig. 1, present example classification of the items algorithm flow chart is illustrated.User's scoring record Data processing is used Family-project rating matrix mxn, while project category matrix is utilized, user-project rating matrix mxn is divided into k classification. That is knm, wherein j are the rating matrix of jth class.Fill each classification matrix J.Matrix element R, it is scoring of the user to project J, It is divided into two kinds of situations:When user explicitly scores project J, its value is taken to set L；And when user does not score project J, it scores Then obtained by algorithm 1, i.e., to arbitrary project, scoring of the user to project J.

To k classification matrix, the similarity between any user in class is calculated, and form user's similarity matrix in class. In the class where destination item, find targeted customer UID user's neighborhood, be set to C and user cl, c2 ... with Family UID similarity is arranged in order from high to low.All neighbours' number m in user's neighborhood Curb are calculated, user UID is set Arest neighbors number be M, work as M>During m, then user UID arest neighbors collection is combined into C；Work as M<M, then preceding M items are taken in C as user UID arest neighbors collection is combined into C.When destination item belongs to multiple classifications simultaneously, respectively in affiliated classification matrix, class is calculated Prediction scoring purD, rrDs of the interior user UID to project IID, then average as user UID to the final pre- of project IID Survey appraisal result.Using strategy (whole classification matrixes as belonging to selection target project or the class closest to average value specified Other matrix etc.), the neighbor user in user's UID arest neighbors set C is selected, their hobby is recommended into targeted customer, is mesh Mark user and find potential new interest.
