DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a production equipment planning system based on a plurality of standard planning models in which a data group relating to a plan and a procedure for determining a data group to be planned in the plan are described as objects. .

2. Description of the Related Art A comprehensive architectural production plan includes, within a large frame of the production plan, a process plan relating to a temporal plan, a construction method plan relating to a plan of assembling columns and beams, a scaffold and a crane. It consists of three pillars of a tentative design related to the planning of equipment such as (lifts). If each of these plans is independently advanced without considering any information of other plans, for example, depending on the contents of the construction method plan, it will be impossible to secure the delivery date in the process plan or it will be inconsistent with the temporary design plan. Or not. Therefore, these plans need to be promoted in a coordinated manner.

[0003]

However, in a conventional integrated system of production planning, a method is adopted in which subsystems of a process plan, a construction method plan, and a tentative design are simply connected in the order of use. In many cases, the system is reconfigured every time a planning function is added or changed.

Further, in the conventional case in which a plurality of subsystems are sequentially used, there are many duplications of inputs and the planning process is not clear. Therefore, if the plan change is repeated, maintaining consistency becomes a problem.

[0005] In recent years, the mechanization of assembly and transportation labor, the use of site plants, and the use of system molds due to the compounding of industrialization of frame structures have been remarkable in the introduction of construction robots in recent years. In addition, the number of production means for which provisional designs are targeted is increasing.

Further, in a systematic process plan utilizing a repetitive property by utilizing a planning method such as a multi-activity chart, an operation plan of a machine such as a crane, a work plan of a crew, a diversion plan of a temporary material, a PC Plant production plans are related to each other, and coordination between the plans is required.

An object of the present invention is to solve the above-mentioned problems, and an object of the present invention is to provide a flexible production equipment planning system in which a knowledge / planning function can be easily added and changed.

[0008]

For this purpose, a production equipment planning system according to the present invention comprises a plurality of standardized data sets which describe, as objects, a data group related to a plan and a data group to be planned in the plan. Standard planning to select a standard planning model from a plurality of standard planning model objects according to the planning model, production facility element information describing the attribute data unique to each element and the unique planning procedure as a production facility element object, and input planning conditions Model selection means, plan model generation means for modifying the model by reflecting the plan conditions from the selected standard plan model object to generate a plan model, and selecting production equipment from production equipment element information according to the generated plan model It is characterized by having a production equipment selecting means.

[0010]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a diagram showing one embodiment of the production equipment planning system of the present invention.

First, the input means 2 includes a building model such as the number of floors and heights (super-high-rise, low-rise), size, structure (steel frame, reinforced concrete), and environmental model such as site conditions and road conditions. This is for inputting other project information, inputting a non-inherited model, and other inputs. The model storage means 3 stores the standard planning model 3-1,
It has model information 3-2. The constraint information 4 is configured by, for example, a storage unit that stores and retains constraint information of another planning system. For example, in the case of a process plan in a building production plan, this information is obtained from a construction method plan or a temporary design drawing. The received constraint information, if it is a temporary design image, is information on various constraints received from a process plan or a construction method plan. Therefore, the constraint information 4 is configured to be connected to another planning system and to apply a constraint by applying a construction schedule priority rule, a cost priority rule, a labor priority rule, and the like from the other planning system to each planning system. It may be. The output unit 5 outputs a plan model and model information thereof. The processing means 1 has a standard plan model selecting section 1-1, a plan model creating section 1-2, and a model selecting section 1-3, and receives input project information, stored standard plan models 3-1 and model information. 3-2. After selecting a standard planning model from constraint information of another planning system, processing such as generation of a planning model and model selection is performed.

[0012] The standard planning model of a production facility is, for example, a type, quantity, arrangement, mutual relationship, etc. of production facilities prepared based on a case in a production facility plan corresponding to a specific production facility for on-site production such as frame construction. Is described as an object, and what the standard planning model has is a planning framework. This standard planning model is organized in a hierarchical structure, and a standard planning model (object) at the instance level is selected according to the planning conditions of a specific project, and the data items and procedures of the plan are transferred to the next planning model. Inherit. The data includes a data group related to the plan, and the procedure includes a procedure (planning procedure) for determining a data group to be planned in the plan.

The plan model of the production equipment is an object generated by giving a project-specific condition to a standard plan model object selected according to a plan condition of a specific project and changing the standard plan model, and based on the standard plan model. And is generated as another object. In this planning model, if the project-specific planning conditions are not fixed, objects are generated in a form similar to the standard planning model, and if there is a lot of condition information, objects defined to a detailed level are generated. Structure. Therefore, it has a flexible structure corresponding to the planning level. The plan model object inherits all the contents of the model, such as the relationship between the production facilities, held by the standard plan model object.

[0014] Production equipment as individual entities such as cranes (lifts) and transfer machines are organized as production equipment element objects, and attribute data unique to each element and a unique planning procedure are described. This production equipment element object is independent of the standard planning model object which is a knowledge base, and exists as a reference object in the external database.

As described above, the production facility planning system of the present invention decomposes a planning problem into a plurality of sub-planning problems, and expresses their interrelationships in a hierarchical network. (Plan model), and each model has a procedure for executing a plan. In addition, this plan model is selected and modified from the standard plan model. Such a plan aiming model object is prepared, the standard plan model object is modified, and the plan is prepared according to the procedures described in the object. Execute.

Next, a description will be given of an example in which the present invention is applied to a crane plan in a frame construction stage. FIG. 2 is a diagram for explaining the outline of the process of the present invention applied to crane planning, FIG. 3 is a diagram showing a classification example of a crane standard planning model, and FIG. 4 is a diagram showing an example of objects of a crane standard planning model. FIG. 5 is a diagram showing a generation example of a crane planning model, and FIG. 6 is a diagram for explaining objects of a crane model (production planning element).

The case where the production equipment planning system of the present invention is applied to a crane will be described. First, planning knowledge is consolidated into a standard planning model 3-1 and rules for selecting this standard planning model are defined in a standard planning model selecting section 1. -1. The standard processing procedure of the system selects a standard plan model from a plurality of standard plan model objects according to plan conditions received from a building model or the like of the input project information, as shown in FIG.

Based on the selected standard planning model, the model is modified by reflecting the project planning conditions, and a planning model in the plan is generated. If the model does not depend on the standard plan model, a non-inherited plan model is generated based on the input information.

According to the generated planning model, a model is selected using information on a model-specific object of a crane which is a production facility element.

The standard plan model of the crane is an object which is organized as a plan pattern based on a plan example of a crane plan at the frame construction stage and is made into an object.

The model includes, for example, an arrangement pattern of cranes that can be set up based on conditions of the site and the building position, a crane type (movable type, stationary type), a building type, a building height,
Are basically classified. In addition, a table is set based on a combination of a crane arrangement pattern and a crane type, and each model is classified in the table.

Each table subdivides the standard planning model according to the combination of the frame shape and site conditions as shown in FIG. The standard planning model is described as an object, has a crane type, the number of cranes, and the like as data items as shown in FIG. 4, and has a procedure for obtaining an installation position as an internal procedure (method).

In the selection of the crane standard planning model, a classification table of the standard planning model is selected from the site conditions of the project information, and a specific model on the classification table selected from the building shape information is selected. If there are multiple models selected, save them as alternatives and proceed with the plan.

The crane planning model has data items necessary for crane selection and a procedure for determining the data. As shown in FIG. 5, site conditions and building shape data of the selected standard planning model are applied. It was done.

The planning model inherits the data items and procedures of the standard planning model, and has specific data items and procedures relating to the maximum suspended load. The maximum lifting load data is
It is received from the building model (frame structure member model), and is data on the weight and position of the maximum suspended load determined by members unique to each frame structure.

Although the planning model is a model derived from the standard planning model as described above, it is also possible for the user of the system to set an original planning model, which is called a non-inherited planning model. The frame structure of the succession planning model is the same as the planning model that inherits the standard planning model. Also, the model can be modified for the inherited model, and the frame configuration of the model after modification does not change. When planning knowledge and data are small like this, the planning can be advanced depending on the model, and when there is abundant data, the planning model can be assembled by inputting the data necessary for the model configuration. A flexible system that can reflect intentions at various levels can be configured.

The crane model information has a procedure for checking the load condition required from the rated load plan model of each crane, and the frame configuration of the object is as shown in FIG. In the selection of the crane model, the object of the crane model information is searched according to the model selection information held by the generated object of the crane planning model. For all models that meet the selection conditions, cost calculation is performed based on the construction period data received from the process model, and final selection information is provided.

It should be noted that the present invention is not limited to the above embodiment, and various modifications are possible. For example, in the above-described embodiment, an example in which the present invention is applied to a building production facility plan, particularly to a crane, has been described, but it goes without saying that the present invention can be similarly applied to other production facility plans.

[0029]

As described above, according to the present invention, the plan function has a procedure for executing the plan according to the object-oriented paradigm, so that the knowledge / plan function can be easily added or changed. Moreover, in the construction production plan, it is broken down into a plurality of sub-planning problems, such as a process plan, a construction method plan, and a tentative design plan, and these sub-problems are further broken down into lower-order problems to construct a network model mutually. This allows for flexible integration of the system.
