Description

Description: TECHNICAL FIELD The present invention relates to a construction management system for managing construction work from a construction planning work before and after construction to various daily works during construction at a construction site.

(Conventional technology) Construction work includes earthwork, geotechnical work, reinforcing bar work, formwork work,
It is a collection of many specialized works such as concrete works.

Further, regarding each of these specialized works, the contents of the work management work range from technical work such as construction plans, quality, and process management to non-technical work such as procurement of labor materials and equipment and various notifications.

As a result, the number of items of construction management work becomes enormous.

The contents of the construction management work can be broadly divided into two: the work at the planning stage and the work at the construction stage.

The outline of the construction management work at the planning stage at the conventional construction site is shown below.

The work site manager (general manager of construction work) assigns the construction subject in charge to each construction management engineer assigned to the site.

Each person in charge carefully reads the design drawings, specifications, and question and answer documents with the designer to grasp the contents.

Based on the content of “”, various materials, and their own experience, clarify the types and quantities of labor, materials, equipment, and work procedures required for the construction subject in charge.

Create a construction drawing of the construction subject in charge,
Develop quality control plans and construction procedures.

Considering the following items, prepare a process plan for the construction section in charge so that there is no conflict with the overall process.

・ Overall process ・ Construction plan of construction work in charge, construction procedure ・ Required work amount and planned labor amount of work in charge ・ Capacity of production equipment such as lifting machines installed on site ・ Process plan of preceding and following construction subjects, Construction plan Procurement of various production resources based on the contents of "" to "" and preparatory work on site.

Taking into account the following items, the work from "" to "" is repeated as necessary.

・ Demand and supply status of labor materials and equipment ・ Progress of management work for preceding and following construction subjects ・ Design change The work manager adjusts the schedule and contents of the work between each construction subject to ensure consistency as a whole construction ,maintain.

On the other hand, the management work at the construction stage has a deeply pure technical color for quality, and there are many contents that can be judged on an objective scale, so the construction management engineer's personal efforts and will can be acquired in a short period of time. It is also possible to do so.

In addition, it is relatively easy to support the company and improve the management level of the entire company.

(Problems to be solved by the invention) By the way, there are many factors that require comprehensive judgment ability in the work at the planning stage. The factors are as follows.

In construction work, the designer of the structure, the supervisor of the construction work, the construction manager (contractor) of the construction work, and the contractor of each specialized work (subcontractor) are generally different economic entities, and each construction phase Communication and coordination until the unification of intentions among the subjects is complicated.

There are many uncertainties in the contents of the design drawings and specifications at the start of construction.

 Design changes are relatively frequent even after construction starts.

Such factors have a great influence on the schedule of the work in the planning stage.

In addition, even in the same construction subject, the procedure and schedule are different depending on the scale, grade, or the way of thinking of each engineer in charge.

In addition, the construction order of each construction subject and the context of management work among multiple related construction subjects are complicatedly intertwined, and these procedures, schedule planning, and so-called scheduling are also important know-how for engineers. The current situation is that it has a great impact on the productivity of the management work of construction projects, and eventually on the quality and construction period of construction, and the safety of construction.

Further, some construction management work is affected by exogenous fluctuation factors / uncertainty factors, such as determination of order deadline in consideration of delivery date. Therefore, the scheduling of construction management work depends largely on the intuition and experience of each construction management engineer, and the following points become problems.

The know-how of construction management largely depends on the experience and is difficult to be objective information. Therefore, comparing the productivity of construction management work,
At every level of individual technicians, its behavior is extremely large. In addition, it is difficult to transfer know-how systematically, and we have no choice but to rely on the accumulation of individual experience in leveling and improving levels.

If the type of structure constructed in the construction is inexperienced for the construction management engineer in charge, a huge amount of time will be spent for basic research, and at the same time it will be natural and common sense for experienced personnel. Management items / procedures /
There is a possibility of misunderstanding.

In the construction industry, the number of construction management engineers is declining, despite the fact that the construction volume in recent years has been stable at a relatively high level. As a result, the amount of management work per person becomes very large, and there is a high risk that management items, procedures, and points will be mistaken due to busy schedules.

In the past, many engineers were in charge of construction, and experienced engineers were responsible for the construction. However, in recent years, due to the above reasons, there are an increasing number of cases where relatively young engineers with little experience have to be responsible for construction work.

Further, conventionally, construction management schedule management software that operates on a personal computer has already been developed as a scheduling tool, but it has the following problems.

It is necessary for the construction management engineer to enter the extremely detailed and enormous amount of initial data such as the schedules of all the work belonging to all the management items. Therefore, the introduction of the system may increase the load.

After all, the value of the data to be input is determined by itself, and there is a possibility that problems similar to those in the case of the conventional method may occur, such as errors in management items, procedures, and points.

Simply displaying the schedule does not provide sufficient support to the construction management engineer.

The present invention has been made in view of the above points, and an object of the present invention is to provide a construction management system that simplifies the input of initial data and facilitates the scheduling of construction management work without individual differences. .

(Means for Solving the Problem) The present invention will be described with reference to FIG. 1 which is an embodiment. The present invention accumulates specialized knowledge about structures and construction techniques and management knowledge about a planning method. In addition, a knowledge base 12 whose knowledge is added and modified by a construction management expert, a man-machine interface 10 for inputting judgment criteria initial data and actual data regarding construction management work, and outputting processing results. By referring to the knowledge in the knowledge base based on the initial data input from the man-machine interface 10, the items, procedures and required days of the construction management work are automatically inferred to schedule the construction management work. Inference mechanism 11 automatically generated,
A database 14 for accumulating the schedule data generated by the inference mechanism 11 is provided.

Further, in the present invention, the inference mechanism 11 evaluates the progress by comparing the input result data with the schedule data stored and stored, and refers to the evaluation result and the knowledge in the knowledge base 12. It is characterized in that it can be configured to infer warnings and advice regarding progress.

(Operation) When the initial data is taken into the inference mechanism 11, the inference mechanism 11
Automatically and appropriately infers the items, procedures, and required days of construction management work based on the initial data based on the knowledge of the knowledge base 12, and automatically generates a schedule of construction management work. This simplifies initial data entry and allows scheduling without individual differences.

In addition, it is possible to automatically calculate appropriate work items, procedures and schedules for each construction subject, and to give warnings and advice to the work of the progress status with respect to daily work. ， The main points are correct and missing
The level of construction management is improved.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings.
FIG. 1 is an overall configuration diagram of a construction work management system.

In the figure, 10 is a man-machine interface, 11 is an inference mechanism, 12 is a knowledge base, 13 is a knowledge acquisition mechanism, and 14 is a database.

The man-machine interface 10 has a menu processing function that allows the user to operate each function of this system in a menu format, an initial data input processing function, a performance input processing function that inputs the actual progress of each work of the user, and Screen display,
It has a print processing function, and the man-machine interface 10 and the inference mechanism 11 are connected via an explanation system 15 for explaining the reasoning process performed to the user. A data input device 16 such as a keyboard, a display device 17 such as a CRT, and a printing device 18 are connected to the.

The inference mechanism 11 refers to the input initial data and the knowledge accumulated in the knowledge base 12 to automatically determine the most appropriate work item, procedure and schedule for each construction subject, and create schedule data. At the same time, the input actual progress status is compared with the created and saved schedule data to give warnings and advice.

The construction work schedule data inferred by the inference mechanism 11 is accumulated in the database 14. Also, the database 14
Stores data such as construction conditions.

The knowledge base 12 stores specialized knowledge about structures and construction technology, and management knowledge about planning methods for more efficient creation of rational process plans in terms of resource input methods and costs. To be done. And these knowledge,
It is designed to be added and modified by a construction management expert through a knowledge acquisition mechanism 13 connected to the man-machine interface 10.

In such a configuration, the second scheduling operation is performed.
It will be described with reference to the drawings.

When the system is started, the man-machine interface 10 displays a list of operation contents that the system can receive, that is, a menu on the display device 17 (step S
1). In the next step S2, one is selected from the menu displayed on the display device 17. For example, if the menu content is
If END, initial data input, schedule output, and actual result input, one of them, for example, initial data input is selected.

When the initial data input is selected, the process proceeds to step S3, and it is determined whether the initial data input is the first time. When it is determined that the initial data is input for the first time, the process proceeds to step S4,
Enter the outline of the entire construction.

That is, by operating the input device 16,
Contract amount, construction area, number of floors, structure, building use, designer,
Enter each data of the administrator and the orderer.

Then, the process returns to step S3 to determine again whether it is the first time.

Since the determination result here is not the first time, the process proceeds to the next step S5, a submenu is displayed, and 1 of this display menu is displayed.
Choose one.

Here, when the person in charge data input is selected, step S6 is performed.
Then, the name of the person in charge, the age, the name of the experience work subject, and the number of floors are input from the input device 16. The input personnel data is stored and saved in the database 14 (step S
7).

Further, when the construction subject data input is selected in the submenu selection step S5, the process proceeds to step S8, and the data of the person in charge, the construction subject name, the quantity, the specification, the planned start date, and the planned construction period are input from the input device 16. Is entered.

In the next step S9, the inference mechanism 11 makes an inference by referring to the knowledge in the knowledge base 12 based on the input initial data, whereby each of the most appropriate construction management work items, procedures, required days, etc. Automatically determine the decision items and automatically create schedule data for construction management work.

Then, in the next step S10, the created schedule data is stored and saved in the database 14.

If the schedule output of the display menu is selected in step S2, the process proceeds to step S11, and it is determined whether the operation is continued.

Here, when it is not continued, the process proceeds to step S1, and when it is determined that it is continued, the process proceeds to step S12. Step S12
Now, select the construction subject.

As a result, the database 14 storing the schedule data is searched (step S13), and the schedule data corresponding to the selected construction subject is output (step S1).
Four).

In step S15, the input work progress status of the construction subject is compared with the created and saved schedule data to evaluate the progress status.

From this evaluation result, it is determined whether or not a work delay has occurred, and it is determined whether or not to issue a warning (step S16).

If it is determined that there is a delay in the work of the construction subject, step
A warning is output in S17. In the next step S18,
Based on the warning data, the knowledge base 12 is referred to, the appropriate advice to the user is inferred, and output to the man-machine interface 10. Then, the result is displayed on the display device 17
To display.

Further, when the actual result input is selected in step S2, the process proceeds to step S20, and it is determined whether the operation is continued.

Here, if the operation is to be continued, the process goes to step S21 to select a construction subject.

In the next step S22, the work of the selected construction subject is selected, and in the next step S23, the actual progress status of the selected work is input.

Then, in the next step S24, the input progress status is stored in the database 14.

Thus, in the man-machine interface 10,
Menu processing is performed to facilitate data input operation, and initial data is input according to the instructions displayed by the menu processing, and construction is performed by the inference mechanism 11 while referring to the knowledge base 12 based on the input initial data. Since the schedule is created by automatically inferring each decision item such as management work items, procedures, required days, etc., the input of initial data is simplified, and in the work plan, each construction subject It is possible to automatically calculate the most appropriate work item, procedure, and its schedule, and automatically set the context of work between construction subjects.

In addition, since the system that can automatically infer the performance evaluation process, the warning, and the advice process, in daily work, in addition to simply displaying the schedule, the progress of each work, various warnings of delayed work and work Can provide means for recovering delays, advice for performing smooth work, etc., as well as instructions for each work and standard necessary documents and drawings by means of a display device 17 and a printing device 18, and a construction management engineer It can also be presented to.

Next, the operation of construction management work by this system will be described with reference to FIG.

First, in step S30, initial data is input.
With reference to this initial data and the knowledge base 12, a schedule table is automatically created and output (step S31).

In the next step S32, construction management work is carried out based on the schedule table.

Then, in the next step S33, the actual progress status of the work is input from the input device 16.

In the next step S34, it is determined whether the construction management work is completed.

Here, when it is determined that the process is completed, the process proceeds to step S35, and the knowledge base 12 is referred to based on the work completion result.

Then, in the next step S36, the result of the work completion is evaluated.

In the next step S37, the evaluation result is stored in the database 14.

When it is determined in step S34 that the work is not completed, the process proceeds to step 38, and it is determined whether there is a work delay warning.

Here, if there is no warning, the process proceeds to step S32, and if there is a warning, the process proceeds to step S39.

In step S39, the warning content is confirmed. Then, in the next step S40, the advice content for the warning is confirmed.

After that, in step S41, the work content and schedule are adjusted and changed, and coordination with other construction personnel is performed according to the advice content.

In the next step S42, the work content, schedule, etc. for which various adjustments based on the advice have been completed are registered in the database 14.

Then, in step S43, a correction schedule table is automatically created and output.

In such construction work management work, the schedule creation and adjustment of the construction management work can be saved, the contents of the schedule can be rationalized, and the items of the construction management work due to busyness, lack of experience, etc. It is possible to prevent errors and omissions in procedures and points, and systematize the accumulation and inheritance of know-how for construction management work.

The present invention is not limited to the above-described embodiments, but can be variously modified within the scope of the claims.

(Effects of the Invention) As described above, according to the present invention, various construction management operations at the construction planning stage are inferred based on initial data such as construction outline and construction process, and a schedule is automatically generated. As a result, it is possible to simplify the input of initial data and
It enables standardization and rationalization of construction management work. As a result, the quality, cost, process, and safety management levels of construction work can be improved, and the productivity of construction management work can be improved.

In addition, in daily work, not only the schedule is displayed, but also warnings and advice on the progress of work are possible, so errors and omissions in the items, procedures, and points of construction management work due to busyness, lack of experience, etc. Can be prevented and the level of construction management can be improved.

Furthermore, by looking at the progress status of the work of the construction subject that is not in charge, all technicians can grasp the whole picture of the management work of the whole construction, so the progress of the whole construction becomes very smooth, and It is possible to increase the weight of the construction management engineer for the purely technical work, which is the essential area of the engineer.
