Establishment of ship construction production plan

Description

Establishment method of producting plan when vessel is constructed

1 is a block diagram showing a method for establishing a production plan during ship construction according to the present invention;

Figure 2 is a block diagram showing the flow in general ship construction,

Figure 3 is a block diagram showing the linking state of a small schedule according to the middle schedule in Figure 2;

The present invention relates to a method of establishing a production plan when a ship is constructed, and more particularly, when manufacturing a ship's production plan, a main production is performed by separating process steps such as assembly and mounting, and processing, designing, etc. It relates to a production plan for shipbuilding that can be separated into plans and supporting production plans that support it, reducing the steps of the production plan and improving the accuracy of the plan.

In general, in order to build a ship, as shown in FIG. 2, the sales plan is started according to the type of vessel (commercial vessel, special vessel, etc.), size (drainage), etc., and a large schedule is planned in the production plan. .

Once the sales design is established, the detailed design and the purchase schedule are established accordingly, and the mid-schedule plan is established to link with the purchase schedule.

When the detailed design and the mid-schedule plan are established, the production design necessary for production is established again, the small schedule necessary for the production is established by department and process, the purchase materials are received, and the production is executed.

Of course, by establishing a production schedule and production plan, personnel arrangement, dock arrangement, workshop arrangement, drying facility schedule adjustment, and outsourcing company schedule adjustment are required for ship construction schedule.

The production schedule of the above-described production schedule is about one year, and then a detailed small schedule according to the time of each department and process.

In other words, when establishing a mid-sized schedule, each department, such as assembly, painting, design, and mounting, and each process such as preceding, trailing, cabin, specialty, captain, captain, and battlefield, establishes a schedule according to the time.

As shown in FIG. 3, this is subdivided according to the production schedule according to the production plan, and then a small schedule plan and a weekly execution plan for processing, assembly, design, painting, and mounting are established, and then executed according to the plan. will be.

For example, when the chairman schedule is established, the detailed chairman stages of the plumbing, neck chairman, and machine chairmen will be separated, and the small schedule plan will be progressed while establishing a weekly plan accordingly.

Of course, the remaining small schedule, such as processing, assembly, painting, mounting will also proceed after establishing the same as the detailed plan.

However, as described above, when the medium schedule plan is established according to the detailed design and the small schedule plan, which is a production plan, is established and proceeded accordingly, the schedule schedule of assembling, designing, processing, painting, and mounting is performed, respectively. The development and progress of the plan is very complicated, and this causes the small schedule to not proceed smoothly according to the weekly execution plan.

In other words, because there are so many departments that carry out small schedule planning and weekly execution planning, it is difficult to check the progress of each, and in the case of correlated processes, for example, the assembly step is completed only after the machining step is completed. Because of the establishment and progress, there is a problem such as delay between ship dryers due to the mismatch of mutual plans and increase of construction cost.

Accordingly, an object of the present invention is to solve the above problems, and the processing and assembly steps that are correlated when establishing a small schedule, which is a production plan according to the medium schedule plan during ship construction, and the preceding chairman, the following chairman and By establishing a plan by dividing the design stage into main production and supporting production respectively, it provides a production planning method for ship construction so that the assembly stage and the design stage are not restricted by the processing stage and the design of the design.

In order to achieve the above object, the present invention, after a large schedule plan and a mid-schedule plan is established according to the sales design and detailed design by the server computer at the time of ordering ship, respectively, according to each department, process according to the medium schedule plan In the method of establishing a production plan when the ship is built each schedule,
When the small schedule plan is established, the post-processes are classified as the main production plan in a process having an association relationship in which one process must be completed to perform the next process,
Pre-processes to be preceded by the post-processes are classified into a supporting production plan;
And a schedule of the main production plan is input to the server computer and the schedule is adjusted, so that the schedule of the support production plan is input to the server computer and adjusted according to the main production plan. .

1 is a block diagram illustrating a method for establishing a production plan when a ship is constructed according to the present invention. A mid-year plan (baseline plan), which is a yearly plan, will be established, and a small schedule (production plan) will be established based on this.

In other words, if a mid-schedule plan for each department and process is established according to the detailed design, a small schedule plan, which is a production schedule for each department and a process, is established in accordance with the above-described medium schedule plan.

For example, the small schedule may be classified into machining, assembly, design, painting, and mounting to establish a plan for each department. Because the chairman, the machineman ... must be finished before or after the design work, assembly, painting, and mounting are classified as the main production plan, and processing and designing are classified as supporting production.

Of course, the criteria categorized into the main production plan and the support production plan are classified into the main production and the support production by classifying the one that can be carried out until the next process, such as the relationship between processing and assembly.

That is, in this embodiment, assembly, preceding design, subsequent design, preceding painting, preceding mounting, and mounting belong to the main production plan, and processing and designing are classified as supporting production plans.

As described above, if the production schedule is established at the stage classified into main production and subsidiary production, processing and designing are classified as subsidiary production, which simplifies the main production schedule and the establishment and progress of main production schedule planning It becomes easy.

In addition, the processes such as assembly, preliminary design, post-design, post, preload, and painting applied to the main production schedule have little or no restrictions on each other and thus do not affect each production process. There is no variable in the schedule of the stages (such as no pre-assembly processing to complete the assembly), thus improving the accuracy of the scheduling.

Of course, the steps categorized into the support plan separately establish the production plan and the machining is established in connection with the production schedule of the assembly, and the design of the chairman is established in connection with the schedule of the preceding and succeeding chairmen.

The main production plan and the supporting production plan are respectively input to the server computer through the departmental client computer and integratedly managed by a predetermined program such as ERP. Enter it on the server computer to have connectivity.

As described above, if the plan is to be changed after the production of the main production plan and the supported production plan input to the server computer, the plan only needs to be changed for the assembly, painting, and mounting plan which are actual production plans.

In other words, when attempting to change the above-described assembly process and design process, conventionally, the assembly, processing, designing, designing, mounting, and painting processes had to be changed in sequence. By changing the bay and making the above-described support and machining process such as the fabrication process and the design process change in conjunction with the main production plan, it is also very easy to change the production schedule plan.

As described above, the present invention classifies the main production plan and the support production plan when establishing the ship production plan (for example, classifying the process that should be finished first in the related processes as the processing plan should be completed before the assembly process as the support plan). By reducing the stage of ship production planning and establishing a supporting production plan, it is advantageous to make the planning and schedule progress smoothly and accurately.
