Description
Technical Field
The invention belongs to the technical field of a comprehensive method, and relates to one of main components of a project or task organization management and target control technology of the comprehensive method, in particular to a method for replacing the method for establishing a project or task organization management and target control plan by establishing a network model, gradually decomposing various projects or tasks, respectively establishing an organization management and target control plan by each level in a table mode, and establishing a project or task organization management and target control multi-level plan system by reverse gradual construction period control.
Background
In the beginning of the fifties of the last century, in order to meet the requirements of scientific research with complex relationships and technical development work organization management, advanced industrial countries in the world have been researched on new plan management technologies in sequence, wherein the U.S. has firstly researched CPM (critical line method) and PERT (plan review technology) successfully, and the methods are established on the basis of a working relationship network model and organically combine the formulation, coordination, optimization and control of a plan, so the method is called as a network planning technology abroad.
The PERT (plan review technology) invented in 1956 in the United states is applied to compiling a research plan of a North Star missile, and more than three thousand enterprises are coordinated, so that the plan is completed two years ahead of time according to preset time; the method is applied to the management and control of Apollo space planning which costs more than four billion dollars and mobilizes more than forty thousand manpower, and achieves good effects.
According to the statistics of the former Soviet Union government, the construction period of a building installation enterprise applying the network planning technology can be shortened by 20%, and the engineering cost can be reduced by about 10%.
In 3 1978, the american society for civil engineering and engineers journal commentary states that this method is currently the only new method for project management and that no new method will appear to replace it in the foreseeable future, and therefore we should enjoy it, use it, and improve it.
At present, network planning techniques are popularized and applied in various advanced industrial countries in the world, such as the United states, the Russia, the English, the Japanese, the French, the Germany, and the like.
The professor of Hualuo heptyl, a famous mathematic scientist in China, sets up a scientific system of an overall method on the basis of absorbing the technical theory of foreign network planning from the national situation of China, and is popularized and applied in production practice from the beginning of sixty years in the last century to obtain great economic benefits.
The network planning technology has the following defects and shortcomings, which influence and restrict the implementation, popularization and application of the network planning technology.
(1) Establishing the restriction of the network model rule of project or task organization management and target control plan and the restriction of the expression mode of the plane network model, so that most of project or task organization management and target controllers cannot complete, especially large or complex projects;
(2) the method is not beneficial to the restriction of the application of the computer technology, the application of the technology depends on the support of the computer technology, the establishment and modification of a network model, the calculation of time parameters, the optimization control of a construction period target, the optimization control of a resource target and the like, and the method is difficult to complete only by manpower;
(3) due to the restriction of application range, the CPM is only suitable for organization management and target control of a series of specific work directly decomposed from positive projects or tasks; PERT is only applicable to the review of non-affirmative project or task milestone targets; with the overall and rapid development of scientific technology, not only most projects or tasks have mixed characteristics, but also the organization method has mixed characteristics;
(4) the necessary functional technologies are lacked, and the main functional technologies are only: construction period-cost optimization technology; the construction period is unchanged, and the resource demand is balanced and optimized; the resources are limited, and the construction period is the shortest optimization technology; and non-affirmative project or task milestone target review techniques;
(5) the main functional technologies all have obvious defects and shortcomings, such as:
1) the construction period-cost optimization technology comprises the following steps: the critical line can be judged only after time parameter calculation is carried out on each line consisting of the critical work, and the project period-cost optimization can be carried out only by calculating the charge rate of each critical work, which is difficult or even impossible in the actual work;
2) the construction period is unchanged, and the resource balance optimization technology comprises the following steps: the optimization method does not consider the dynamic condition of resource demand of non-key work in the local (or maneuvering) time difference range, and is obviously unreasonable;
3) the optimization technology has the advantages of limited resources and shortest construction period: arranging the work started before the optimization time period at the most important head, and not considering the influence of the optimization of the non-critical work started before the optimization time period on the construction period;
4) the evaluation technology of the non-affirmed project or task milestone target does not consider the non-key milestone target interval Lagi-jThe impact on the estimated variance, etc.
The network planning technology is free of a method for establishing a project or task organization management and target control multi-level plan system by adopting reverse step-by-step construction period control, wherein step-by-step decomposition is adopted for various projects or tasks, and organization management and target control plans are respectively formulated at all levels.
The network planning technology belongs to a coordination method, and is one of application technologies of the coordination method; it can be said that the network planning technique is a orchestration method, and not vice versa.
