Description

A kind of qualitative Time Optimization method of reversed gradual control multistage organization planning system

Technical field

The invention belongs to critical path method technical fields, are the masters of critical path method project or taskings management and target control technology Want one of component part, specifically, be it is a kind of use qualitative Time-cost optimization method, by each intermediate item or task use by Grade is decomposed, formulation respectively at different levels organizes and target control plan, by the project or task that reversely duration control is established step by step Organization and administration and duration of the target control multistage system of planning, be optimized to shorter than or equal to the target duration method.

Background technique

Eighties of last century early fifties, in order to be applicable in the development of production and the scientific research and technological development of relationship complexity The managerial needs of job engineering, each advanced industrial country has all successively carried out the research of planning management new technology in the world, wherein Successfully CPM (critical path method) and PERT (programme evaluation and review technique) is studied in the U.S. first, is established due to such methods and is closed in work It is the formulation of plan, coordination, optimization and control organically to be combined, on the basis of network model so being referred to as in foreign countries For network planning technique.

The U.S. is applied to the development of establishment Polaris missile in the PERT (programme evaluation and review technique) of invention in 1956 at that time Plan, has coordinated 3,000 many enterprises, and making plan, two years ahead completes on schedule；It is applied to cost more than 400 again later Hundred million dollars, mobilize manpower more than 40 ten thousand Apollo space program management and control, obtain good result.

It is counted according to kremlin, the construction and erection enterprises of application network planning technique, the duration can shorten 20%, engineering Cost can reduce by 10% or so.

In March, 1978, civil engineering association, U.S. proceedings comment on that this method is current only planning management newly side Method, and in foreseeable future, it is not in the new method of one kind to substitute it, therefore, we should enjoy it, use It, improve it.

Currently, each advanced industrial country, such as the United States, Russia, English, day, method, moral in the world, is all promoting and applying network planning skill Art.

The famous mathematician Hua Luogeng professor in China, from the national conditions in China, absorbing, external network planning technique is theoretical On the basis of, " critical path method " scientific system is established, and since eighties of last century early sixties, promotes answer in production practice With achieving huge economic benefit.

Since network planning technique is there are following many defects and deficiency, influences and restrict pushing away for network planning technique Row is promoted, popularization and application:

(1) restriction and planar network of project or taskings management and target control plannet model rule are established The restriction of model tormulation mode manages most projects or taskings and is unable to complete with target control person, especially compared with Big or more complex project；

(2) it is unfavorable for the restriction of computer technology application, the application of such technology depends on the support of computer technology, net Foundation, modification, the calculating of time parameter, the optimal control of constructing aims and optimal control of resource object of network model etc., only It is difficult to complete by manpower；

(3) restriction of application range, CPM are only applicable to type project or task certainly and are directly decomposed into a series of specific works Organization and administration and target control；PERT is only applicable to the evaluation of non-type project or task milestone target certainly；And with section Comprehensive fast development of technology, not only most projects or task have the feature of mixed type, and method for organizing also has There is the feature of mixed type；

(4) lack necessary function technology, major function technology only has: time-cost trade-off technology；Duration is constant, money Source demand balance optimizing technology；Resource is limited, duration most short optimisation technique；It is commented with non-type project or task milestone target certainly The technology of examining；

(5) all there is apparent defect and deficiency in major function technology, such as:

1) it time-cost trade-off technology: needs to carry out time parameter meter by the route that key job forms to each respectively After calculation, critical circuits can be just judged, need to calculate the rate of each single item key job, just can be carried out the optimization of duration-cost, This be in practical work it is highly difficult, it is even impossible；

2) duration is constant, resources balance optimisation technique: its optimization method does not consider non-key work in part (or motor-driven) Resource requirement current intelligence in time difference range, hence it is evident that unreasonable；

3) resource is limited, duration shortest optimisation technique: the work started before the period will be optimized and come most important first place, Do not consider influence size of the optimization of the non-key work started before the optimization period to the duration；

4) Evaluation technology of non-type project or task milestone target certainly, when not considering non-key milestone target interval Between Lag_i-jInfluence etc. to estimate variance.

Network planning technique belongs to critical path method, is one of application technology of critical path method；It may be said that network planning technique is system Method is raised, not vice versa.

The optimization and control of target duration is the target control of critical path method project or taskings management and target control technology One of system, embodiment is that Hua Luogeng professor is pointed: using critical path method, wanting the time to key job.

Since the time-cost trade-off method of traditional network planning technique haves the defects that following many and deficiency, influence And restrict the application of time-cost trade-off method:

(1) type project or task certainly are only applicable to and is directly decomposed into a series of specific work, the organization and administration of formulation Target Time Optimization and control with target control plan, and it is not suitable for overlap joint project or taskings' management and target control The target Time Optimization of plan and control；

(2) method for judging project or taskings management and the critical circuits of target control in the works, it is right respectively to need Each carries out time parameter calculating by the route that key job forms；

(3) need to calculate the rate of each single item key job；

(4) it does not identify project or taskings manage and the method for target control planned target duration；

Do not have each intermediate item or task using decompose step by step, it is at different levels formulate respectively organization and administration and target control plan, by The Time Optimization method of project or taskings management and the target control multistage system of planning that reversely duration control is established step by step Deng.

Summary of the invention

Present invention direct basis project first or taskings' management and the target control multistage system of planning judge key lines Road, then by the qualitative Time-cost optimization method away from, " work " deadline when critical circuits, overlap joint, by project or times The Time Optimization of business organization and administration and the target control multistage system of planning is to shorter than or equal to the target duration.

For the present invention by project or task by organization and administration and target control requirement, " work " decomposed is divided into type certainly " work " and non-type " work " two types certainly:

(1) certainly type " work ": completing time t required for " work "_i(or T_i) it is affirmative；

(2) non-affirmative type " work ": the time needed for completing " work " is non-affirmative, need to be carried out using three point estimations Complete the estimation of " work " time:

1)a_T、m_T、b_T, D_T=(a_T+4m_T+b_T) ÷ 6, σ_T ²=[(b_T-a_T)÷6]²

2)a_t、m_t、b_t, D_t=(a_t+4m_t+b_t) ÷ 6, σ_t ²=[(b_t-a_t)÷6]²

(2) organization and administration of the second level of project organic management and the target control multistage system of planning and target control plan, pass Total time difference is equal to zero, i.e. TF in the works for the organization and administration and target control of key sub-item_i=0 individual event mesh is project organization pipe Reason and the crucial individual event mesh in the target control multistage system of planning；Interval time between crucial individual event mesh is equal to zero, i.e. Lag_i-j =0 route is the critical circuits of second level organization and administration and target control plan；

(3) management of the three levels of organization of project organic management and the target control multistage system of planning and target control plan, are closed Total time difference is equal to zero, i.e. TF to the organization and administration of key individual event purpose in the works with target control_i=0 work is project organic management With the key job in the target control multistage system of planning；Interval time between key job is equal to zero, i.e. Lag_i-j=0 Route is the critical circuits of three levels of organization's management and target control plan.

The method and sequence of Time Optimization of the present invention: by the level-one of project organic management and the target control multistage system of planning It organizes and starts with the Time Optimization of target control plan, optimization sequence is as follows with method:

The optimization of bonding relation is carried out first: taking technology and organiztion measure, the sub-item that will successively carry out as much as possible (bonding relation FTS, and the sub-item of LT=0) is optimized for overlap joint organizational form, optional STS (LT_i)、FTF(LT_j)、STF (LT_i, LT_j), STS and FTF (LT_i, LT_j), STS and STF (LT_i, LT_i', LT_j), FTS and STF (LT, LT_i, LT_jOne of)； LT_i、LT_{I '}Desirable T_i50%~70%；LT_jDesirable T_j50%~70%；

When the sub-item successively carried out has multiple groups, after sorting by the following method, to coming group between last sub-item Relationship (bonding relation) is knitted to optimize:

(1) the tight preceding sub-item duration (T_i) long；

(2)T_iIt is identical, σ_i ²Small；

(7)R_jAlso identical, then tight preceding sub-item earliest may the time started (ES_i) early；

(8)ES_iAlso when identical, it is tight before sub-item sort in the works in organization and administration with target control it is preceding.

Note: when the formulation of project organic management and target control plan, do not consider that every " work " unit time mainly provides The requirement in source, by R_i=0 carries out the optimization of duration.

When being overlapped away from optimization: in the case where no optimizable bonding relation, take technology and organiztion measure, Away from, optimization sequence when shortening overlap joint as much as possible are as follows: FTS (LT ≠ 0) → STS → FTF → STF → STS and FTF → STS with STF → FTS and STF；When can be overlapped by original away from 60%~80% optimize；

When the sub-item that identical overlapping mode carries out is by multiple groups, after sorting by the following method, to coming last subitem Away from optimizing when overlap joint between mesh:
