Abstract
Provided is a project planning, tracking and predicating method. Planning, tracking and predicating of the project can be achieved by dividing the project into a serial of task rectangles with certain relationship. In tracking, actual input resources in the past time and lasting time are represented by completed task rectangles which are unchangeable. Certain amounts of the task are completed in the past time and unchangeable. By utilizing the corresponding relationship of the completed task rectangles of the past time and the amount of the completed task and the corresponding relationship of the uncompleted task rectangles of future time and the amount of the uncompleted task, the rectangles of task in the future time can be predicated. In the future time, the expansion and contraction of time edges of the task rectangles can be achieved by changing the height of data edges of the task rectangles, the expansion and contraction of the time edges of the task rectangles lead to change of the height of the data edges, and accordingly the predication to the whole project can be achieved by utilizing the relationship of the task rectangles.
Description
Affiliated technical field
The present invention relates to a kind of method of project management, can utilize the method for this project management to realize decomposition, plan, tracking, prediction project task.
Background technology
At present; Known project scheduling arrangement method; Be generally gunter drawing (Gantt chart) method, be about to project decomposition and be after a series of work to represent the duration of work with the length of line segment, rule of thumb confirm each start time of working after; It is arranged in the program relation between can not the embodiment task in the chart.Another kind method is a Network Program Method, and after the duration of promptly working confirmed, the relation between the job search (representing with the time difference) was confirmed the priority arrangement of work according to the relation between the work, the relation between can the embodiment task in chart.The problem that exists is when the task in the project is followed the tracks of; Like work when at the uniform velocity carrying out; Regard the line segment total length as 100% workload; Accomplish 30% length at line segment subscript notes 30% like workload, the time of correspondence position and the difference of supervision time are regarded the time that work shifts to an earlier date or lags behind as; Essence can not be that above-mentioned difference is (under the constant prerequisite of former input resource in the time that task under the constant situation of the resource of finishing the work prolongs or shifts to an earlier date; Task Percent Complete and duration have not been the original plan corresponding relation; Concrete visible my special article is discussed) time that promptly task will prolong or shorten completion under the constant situation of resource do not know; Maybe will keep the original plan duration constant, resource will increase the amount of minimizing and not know.Can't realize prediction, and this only is for the at the uniform velocity plan of progress to future work time and resource, the problem of existence, and at the uniform velocity make progress work and can't carry out tracking prediction especially for non-.
Network planning only is that these work are coupled together (during use apart from relation) with certain logical relation; Because of representing that with line segment there are the problems referred to above in duration expression work itself; Nature with the network planning of formation have the problems referred to above equally; Can not the project duration consequence that produce be predicted (preceding forward line commonly used result that the project duration is carried out prediction result is wrong, sees that specifically I discuss by special article) to existing the input.Adopt travel-time table to reach the relation between the task simultaneously, when task can not be carried out according to plan, between the work the time be not that a fixed value will take place to prolong or the variation of shortening apart from relation, more cause the mistake that predicts the outcome.Be that traditional method can not realize tracking, the prediction to project duration, resource, only can carry out temporal plan project.
Can not carry out tracking prediction to the project duration in order to overcome existing method, even or the result of prediction generating also be wrong, the present invention provides a kind of project scheduling, tracking, forecast method, realizes the project scheduling, tracking, prediction.
The technical method that the present invention adopts is: the task in the project (work) is adopted task rectangle (resource rectangle) expression; A vertical edges that constitutes certain area figure, area figure of task rectangle representes that resource, another horizontal sides represent duration; The area figure that resource accumulation (product of resource and duration) in time constitutes is referred to as the task rectangle; Promptly the figure with certain area has replaced the former line segment of representing work, here with the unified task that is referred to as of each work.
The resource here is a generalized concept, and for the factor of all driving tasks or project, we all are referred to as resource, and we also are referred to as resource like abstract concepts such as tensity etc.
The resource here can be a constant amount; Or the amount of phase change; Or continually varying amount; The constant amount task rectangle of accumulating formation in time will be a rectangle in this way, and the task rectangle that constitutes when the accumulation in time of continually varying amount will not be the rectangle stack of a plurality of small rectangle task rectangles (or can be regarded as), still be referred to as (because of a large amount of situation of reality are rectangle) with the task rectangle here.
A project can be decomposed into a plurality of task rectangles, and project can be regarded the stack of a plurality of task rectangles as, and the task rectangle that a plurality of task rectangle stacks form is claimed most project task rectangle.Can certainly carry out the stack of some task rectangle on demand,, the task rectangle under the contract superposeed, form contract task rectangle as according to the contract.
There is certain restricting relation between the task rectangle that project decomposition goes out; These restricting relations are sought out, utilize symbol that these restricting relations are explained out, connect these task rectangles; Constitute a series of task rectangles that are mutually related; Be referred to as to concern task rectangle (or being referred to as to form network, formation network task rectangle), the chart of drawing is referred to as " concerning the task histogram ".
Tracking through to the task in " concerning the task histogram " realizes the tracking to project, and As time goes on some tasks will be in the implementation process, adds up the interior performance of time in the past of these tasks; The resource and the time of dropping into; Represent that with the task rectangle (like a certain task is 100 squares, and actual performance is 20 squares, and input is 10 people; Elapsed time is 2 days, and then the task rectangle in the time in the past is: 10 (resource) * 2 (time)=20 (task rectangle amount); The task rectangle amount of 80 squares of correspondences of residue is measurable in the Future Time is: 80 (task amounts square) * 20 (task rectangle amount) ÷ 20 (task amount square)=80 (task rectangle amounts)), get final product.Also can adopt the mode of Percent Complete, calculate the number percent that intact task quantities accounts for the quantities of whole task, make and drop into consistent with it the getting final product of number percent that task rectangle amount accounts for whole task rectangle amount.Prediction for task rectangle in the Future Time; What adopt here is the consistance with the proportionate relationship of the proportionate relationship of task rectangle in the time in the past and task performance and interior task rectangle of Future Time and task performance; Predict task rectangle amount in the Future Time, also can adopt other proportionate relationship, like the proportionate relationship that provides by norm; What be that resource characteristics adopts is social average ability characteristic, is not the existing resource capability characteristic that drops into.Also can remove the unsettled part of resource capability characteristic in the time in the past, adopt the corresponding relation of the intact amount of resource capability steady component and task to predict the task rectangle amount in the Future Time.Can consider more accurately that for making prediction the resource capability characteristic can change in different time to some extent; Comparative Examples relation revise (as winter with summer resource ability characteristics possible different; When the time in past when winter, Future Time was summer; When the proportionate relationship between application winter service rectangle and the task performance goes to predict that Future Time is the task rectangle in summer, possibly revise) the proportionate relationship in winter.
Dropped into the task rectangle and occurred in the time in the past, immutable, only need to describe strictly according to the facts; The task rectangle is not implemented in the Future Time; After prediction was accomplished, area was certain, can be through raising or reducing the resource limit; Cause the time limit shortening or prolongation (shorten equally or time expand the limit, cause the rising or the reduction on resource limit).Cause the whole variation that concerns the task histogram through the relation between the task rectangle, realize prediction project.
With the passing of time; Future Time in " concerning the task histogram " will constantly become history the time, and prediction item status therebetween will constantly become the situation of actual generation, find out and utilize project a situation arises in the time in the past that (situation can be accumulated utilization; Promptly as gathering once the then situation in situation prediction first all backs Future Time in the time point in first week first week capable of using weekly; Time point in second week utilizes first week and the second all situation, in by that analogy), still continuable constant (like the resource capability characteristic) in Future Time; Go to predict Future Time the project situation, accomplish until project.The finished item actual conditions are to the covering of prediction case, and " concerning the task histogram " shows as intact task rectangle not intact task rectangle is covered." concerning the task histogram " is converted into the project reality record diagram from initial prognostic chart, and with the continuous increase of actual conditions to the overlay capacity of prediction case, predicts the outcome more accurate.
The method that project is followed the tracks of is, and draws the not coverage diagram of intact task rectangle of the intact task rectangle of reality to prediction in the past in the time, in Future Time, draws the not intact task histogram of residue task.The intact task rectangle that " concerning in the task histogram " do not drop into or the task rectangle that takes place all can be referred to as to predict.
We are in the past and Future Time interface point place in residing arbitrary moment in the time lapse process, and it is immutable to be in the time in the past project status, also needn't review, and are in that project status takes place as yet in the Future Time, can arrange and change.Through to project situation in the time in the past parse the characteristic that can extend in the Future Time, and be that factor is removed project status in prediction or the adjustment Future Time with this characteristic.Be different from original employing actual conditions and plan contrast and review in the past the mode of thinking come track project.
Concern that the represented project scheduling of task histogram need carry out, also need rely on fund, personnel, material, etc. supply; The supply of fund, personnel, material etc. itself has regular hour and process, with these times and process; Set up the fixation process module; Find out the relation between (foundation) these procedure modules and the task rectangle, utilize symbol that these relations are explained out, set up being connected between procedure module and the task rectangle; Form dissimilar task histograms, like " payment funding task histogram ", " personnel concern the task histogram ", " material concerns the task histogram ".When " concerning the task histogram " changes because of the tracking to project causes, the situation in the above-mentioned figure Future Time also will be followed variation, and the situation in the time in the past will be described according to actual conditions strictly according to the facts.
The invention has the beneficial effects as follows; The still constant factor in Future Time that dependence and the accumulation that can separate out each task and each key element in the project utilizes that project shows in the time in the past; As component of forecast to following project situation; Realization is to Future Time mean terms purpose duration, resource, and fund etc. are predicted and arranged to reach the record to project situation in the time in the past.
Below in conjunction with accompanying drawing and embodiment this method is further specified.

Embodiment
The title of each task (1) fills in the work title hurdle in Fig. 1; The task rectangle (2) of corresponding each task (1) fills in the progress hurdle; The accumulation of resource (3) on the time (4) constitutes task rectangle (2); And the height (quantity) (5) of mark resource (4), show among the figure that the height of resource (3) in the task completion phase in when plan is constant, as resource limit (4) in the completion phase when the plan highly difference then should be decomposed into different task task rectangle; Or with the expression of the resource (3) of corresponding ratio differing heights, resource height (quantity) (5) correspondence marks respectively.
The task status that this example adopts is described the restricting relation between formula (previous task state description formula (8), this task status are described formula (9), rearmounted task status is described formula (20)) the statement task.
The preposition relation (6) of each task (1) or be referred to as restricting relation in the analysis chart is inserted preposition relation (6) preposition relation in the hurdle in Fig. 2 of each task (1).Preposition relation (6) is numbered (7) naturally by previous task, and previous task state description formula (8), this task status are described formula (9), constitutes the expression formula of the preposition relation (6) of this task.
Need after the foundation excavation task is accomplished, just can construct like the foundation construction task; Then the foundation excavation task is the previous task of foundation construction task, concerns in the hurdle that the expression formula of preposition relation (6) constitutes in that foundation construction is preposition; The foundation excavation task is numbered (7) naturally, writes and does 1; Previous task state description formula (8) (being the state description formula of foundation excavation task) is write and is a100% (a representes area, 100% expression area completed percentage); This task status is described formula (9) (being the state description formula of foundation construction), writes and is a0% (a representes area, 0% expression area completed percentage).Promptly number 1 and be the identiflication number of task, the task status of 1 bottom is described the state description formula of formula for numbering 1 corresponding task, and the state description formula of foot is the state description formula of this task.
Concern in the hurdle as the form removable task is preposition; The previous task of 3 these tasks of expression (form removable) is the 3rd main body construction; A100%t7 representes the state description to the 3rd task, after promptly the intact task rectangular area (a representes area) of task reaches 100% again through 7 days (t express time); A0% representes the state description to this task, and promptly the intact task rectangular area (a representes area) of this task is 0%.The expression previous task accomplishes that this task begins after 7 days.Promptly, describe the state of this task, realize related at this basic point with the basic point that appears as of the state point of preposition task description.
Except that the area (a) shown in this, the time (t), can also resource height (s) (like the resource height arrival value of a certain previous task time after a task just possess the beginning condition) cycle (T) (like a certain period of state property phase appearance of a certain previous task; A certain state also periodically appears in this task); The mode that promptly adopts multivariate to describe; Rather than work (task) relation in the common network planning is only described with the unitary variant of time; When being alleged apart from relation (problem and mistake about the time spent exists apart from the relationship description work relationship specifically referring to the relevant article that I delivered, no longer detail here)
Tightly move forward to the position of satisfying preposition relation (6) (modes that available many wheels move, specific practice sends out article relevant referring to me, here detailed description no longer) according to the time location of the preposition relation (6) of each task (1) the task rectangle (2) that each task (1) is corresponding.
The rearmounted relation of this task of searching (1) promptly follows this task (1) closely afterwards, because of this task (1) reason limits the task (1) of its start time, postposition relation (18) is filled in rearmounted the relation in the hurdle.Essence only needs to concern that preposition seeking the task of containing this task (1) the preposition relation (6) of (7) of numbering naturally in the hurdle inserts this task (1) rearmounted task thereafter and concern in the hurdle, and changes the numbering naturally of the script task (1) on it (7) into rearmounted task and number (7) naturally and get final product.Wherein prepositionly concern that the previous task state description formula (8) in the hurdle becomes, rearmountedly concern in the hurdle that this task status is described formula (19), this task status is described formula (9) and is become, and rearmounted task status is described formula (20).
Civil engineering task rectangle (2) is by foundation excavation, foundation construction, main body construction, form removable among Fig. 1 among Fig. 3; Task rectangle (2) stack constitutes; Form civil engineering contract task rectangle; Curtain wall construction, indoor installation, all corresponding corresponding contract of interior decoration construction also should be the stack of a plurality of task rectangles (2), do not do in the present embodiment one by one and launch.Through Fig. 3 can be that unit realizes the contract performance is followed the tracks of with the contract.
Task rectangle (2) is the project task histogram of the stack formation of all task rectangles (2) among Fig. 1 among Fig. 4, can realize on the whole the duration and the running resource input situation of project are held through Fig. 4.
Follow the tracks of in the face of task down:
Fig. 5 for track to second when week the project situation; Add up through field condition at first weekend, the foundation excavation task is accomplished, and input is a digging machine; Represent and blacking (intact task rectangle) with task rectangle (2) on the construction speed hurdle that then mark task rectangle (2) highly (5) is one.
Add up foundation construction at second weekend and begin to have dropped into 50 people from task, then in the past in the time intact task rectangle (2) be resource (50 people) to accumulation in time at second weekend, see among Fig. 5 that task rectangle (2) blacking is partly represented in the foundation construction progress hurdle.It is 70% that the foundation construction task of this moment is accomplished; Maintenance task completed percentage is identical with task rectangle ratio, and then intact task rectangle also should account for 70% (be blacking part task rectangular area account for whole task rectangular area 70%) of whole task rectangle, draws task histogram (2) in second all foundation construction time in the past and the Future Time; Shown in the foundation construction construction speed hurdle; Dash area is that not intact task square in the Future Time (can be like the manual drawing concrete steps, calculates not intact task rectangular area earlier, 50 * 7 * 30% ÷ 70%=150; Then excess time, edge lengths was 150 ÷ 50=3; Resource limit height is 50 still, in Future Time, draws rectangle, and paints dash area with oblique line and get final product)
When adding up field condition second weekend, find the main body construction task; Beginning to drop into resource (5) 200 people in second the 5th day week constructs; Then in the corresponding time of origin in construction progress control hurdle, draw intact task histogram equally, shown in the main body construction progress hurdle.This moment, the statistical subject construction task accomplished 4%, kept the task completed percentage identical with task rectangle ratio, and then the not intact task rectangle in Future Time should be 96%.Method for drafting is the same, and is as shown in the figure.(as comparing with Fig. 2, can find that the main body construction start time is ahead of schedule, reason is fulfiling ahead of schedule of foundation construction, for main body construction gets into the condition that provides).Shifted to an earlier date though find the main body construction task start time, it will be 17 01 days weeks that the duration will exceed 16 durations in week of original plan duration this moment.Put aside that to adjustment, because of causing the main body construction task of whole claim for eot, resource is accumulated the task rectangle that forms this moment, still unstable to the output of task.
Fig. 6 is the project situation when tracking to for the 3rd week, and the project field condition is added up, and the height (5) of resource (3) still is 200 people, then draws among intact task rectangle such as Fig. 6 main body construction task rectangle blacking part.Adding up the quantities completion this moment is 20%, keeps the intact task rectangle ratio of intact task rectangle identical with project completed amount construction in progress amount ratio, the intact task rectangle of the same drafting of method.Thereafter the task rectangle in the Future Time that is associated moves according to relation is corresponding.Find that the duration will be above 16 weeks of plan this moment; To be extended down to for 17 01 days weeks; As think that the project duration can not accept; Then need adjust the resource reduction of erection time, the adjustment that can be conceived to this job rectangle resource (3) also can be conceived to the adjustment of other job resource (3), and the resource of actually adjusting which task shortens the duration in the Future Time; Need take all factors into consideration the cost that field condition contractual relation and resource increase bring, adjust the duration in the project Future Time with the resource of adjustment main body construction task below.
The task histogram that concerns shown in Figure 7; For requiring main body construction still to accomplish by being arranged in the original plan in 5 weeks, promoting main body construction task rectangle resource (3) limit, to be moved to the left (4) edge lengths of whole task rectangle time be former 6 weeks, because of the task rectangular area constant; (3) limit of corresponding time will be increased to 288 people, and (manual drawing can be read main body construction in Fig. 6; Not intact task rectangle time span is 36 days in the Future Time, highly is 200 people, and then not intact task rectangular area is 200 * 36=7200 not.7200 ÷ 26=277 people.) this moment engineering will 15 the week 05 days completion, be lower than for 16 weeks.
Project situation when Fig. 8 tracks to around the; The project field condition is added up, and the height (5) of resource (3) is 277 people, directly main body construction task rectangle blacking is all around got final product; The main body construction task amount has accomplished 45% around the statistics the;, the ratio that keeps intact task rectangle not finish the task rectangle is identical with the ratio of project completed amount construction in progress amount, then can obtain remaining task rectangle ((200 * 9+277 * 7) * 55% ÷ 45% ≈ 4570).To remain the task rectangle and be plotted in (duration is 4570 ÷, 277 ≈ 16) among Fig. 8.The corresponding corresponding adjustment in task associated task rectangle position, then as shown in Figure 8, predict that the whole duration was 15 02 days weeks.
Fig. 9 is that the stack (contract) of Fig. 8 concerns the task histogram; Mainly be used for the contract is that unit follows the tracks of the contract implementation status; When to the task rectangle (2) that concerns the task in the task histogram when following the tracks of, this figure will be through obtaining after task rectangle (2) stack to task automatically.Will completion after 802 days weeks at measurable civil engineering contract around the, as contrast and will be finished in advance former 9 weeks of contract.
Figure 10 is the tracing figure of project task histogram; Stack for all task rectangles among Fig. 8; Through with the contrast of original plan project task rectangular profile line (10), can the knowledge project drop into the variation of resource, prediction duration and the possible situation of back hysteresis in advance of duration contrast in the original plan.To fulfil (intact task rectangle is on outline line (10) left side) ahead of schedule in prediction all around in this example.Not more clearly in the presentation graphs task rectangular profile line can use other color showing.Can hold the integral body progress and the input situation of project intuitively through project task rectangle tracing figure.
Figure 11 concerns the task histogram for contract payment, and payment process module (11) is carried out relatedly among the figure through payment task relation (13) and task rectangle (2), and when task rectangle (2) when changing, payment process module (11) is followed the occurrence positions variation.The formation of payment process module (11) is paid the horizontal line (14) of duration and the payment fracture phase (5) and arrow (15) formation of horizontal line (14) fracture that duration is paid in expression by expression in the drawings.When arrow (15) representes to estimate payment during for wave, when arrow (15) is represented to pay during for solid line.Payment process module (11) is set up according to an engineering demonstration contract in this illustration, and like the demonstration contract requirement (CR), the engineering payment in advance should be earlier than the first seven day of starting date; Do not pay after 7 days, the employer sends and wants money notice, still nonpayment; Stop construction after 7 days, know that thus the whole time of payment is two duration horizontal lines (14) of seven days, but have a fracture phase (12) (why to be referred to as the fracture phase between seven days at two; Be because it makes the fracture of duration horizontal line; And this part duration possibly be an open season for zero also maybe be very long, unpredictable.Like this example, the employer possibly in time send out public notice after 7 days, also possibly fail in time to send out public notice, or the employer has the reasonable ground of nonpayment etc., and causing this fracture phase is also can not know a couple of days or last month, and the whole procedure module time is with corresponding prolongation).Payment arrow (15) can slide backwards on procedure module (11) rear end (16), and expression so far all meets the payment agreement.Setting up of corresponding progress money and settlement money payment process module (11) thereafter is similar.
In this example; Payment process module (11) is represented with model front end (17) and the model rear end (16) and the relation of task rectangle (2) with the relation of task rectangle (2); If expression be payment process module (11) front end (17) and task rectangle (2) relation the payment task that fills in task concern the top in the hurdle, if rear end (16) then fill in the below that the payment task of task concerns the hurdle.
In this example; What the expression formula top of payment task relation (13) was represented is the state point of task rectangle (2); What the bottom was represented is the distance (represent that like a100% task rectangle (2) completion is 100% end point, t0 representes that the front end (17) of procedure module (11) is 0 apart from the time gap apart from this state point) of the state point of procedure module (11) front end or rear end and task rectangle (2).
In this example, payment task relation from left to right each row order each row order is corresponding from left to right with the hurdle inner model, the relation of expression procedure module (11) and task rectangle (2).
Figure 12 is the tracing figure around Figure 11 to the time, and the variation that concern the task rectangle according to stack (contract) concerns according to the payment task and obtains automatically.Payment in the time in the past fills in the table according to the actual delivery situation to be represented with solid arrow (15), and the payment in the Future Time is obtained with wave arrow (15) expression by payment task rectangle relation, and the amount of money adjusts according to the payout status in the time in the past.
Contract payment concerns the task histogram; Can follow the actual development situation of project; Understand easily and when to pay in the fund and the future of having paid; And the slip phase of payment (refer to that fund is paid the earliest and paid interlude at the latest in the scope that regulation allows, fund at this moment between in the section, the random time payment all can.) how long have.Through prediction to paying the bill in the Future Time, be convenient to prepare fund in the appropriate time, reduce financial cost.
Figure 13 concerns the task histogram for material, and material arrival process module (11) is through setting up the contact with task rectangle (2) with material task relation (13) among the figure.The time that horizontal line (14) expression material arrival continues is (in the task foundation construction; The arrival on prefabricated basis possibly spend two day time from first car basis arrival to all prefabricated basic arrival of last car, then uses two days durations of horizontal line (14) expression); Link to each other with free float (17) thereafter (by row's free float; Purpose is under situation about meeting accident, and leaves the processing time, guarantees that goods arrives).
Figure 14 is consistent with Figure 13, and the name of material among Figure 13 is filled in the name of material hurdle, and the procedure module among Figure 14 (11) is consistent with the procedure module (11) among Figure 13.It is convenient more clear than Figure 13 to make to the observation of material time of arrival.The foundation of material task relation (13) and explanation are with aforementioned payment task relation (13)
Figure 15 for Figure 14 track to around the time figure; The time in the past material arrives and fills in the table according to actual conditions; With solid arrow (15) expression, arrives the actual duration with horizontal line (14) expression, procedure module rear end (16) move according to material relation (13) that (purpose is to know that material arrives and the time interval of reality use; Can select procedure module rear end (16) related with material (13) not related, free float (17) is not drawn yet.), the material in the Future Time obtains according to material relation (13) moving process module (11) time of arrival automatically.Shift time will move after free float (17) will not cause the task rectangle as being no more than behind wave arrow (15) in the material supply procedure module (11) in the Future Time; Move after when surpassing free float (17), will causing corresponding task rectangle (2) according to material task relation (13); The back Mobile Communication of task rectangle (2) is the relation of putting (18) later; Cause moving of a series of task rectangle (2) again, form in the case concern the task histogram.
Figure 16 is the corresponding material supply figure of Figure 15.
Corresponding above-mentioned same procedure; That adopts sets up different procedure modules according to different requirement; Through the related method of task relation foundation with the task rectangle; Also can set up construction equipment and concern that task histogram, workmen concern that task histogram, contract formulation concern the task histogram, project concerns task histogram etc. in earlier stage, here narration no longer one by one.
