1 is a road through which a schematic view of the interrelationship between a simulation system for mid-scheduling evaluation and a mid-schedule planning system according to an embodiment of the present invention, the mid-schedule through a simulation before finalizing the mid-schedule plan established in the mid-schedule planning system After verifying the establishment result, the process of confirming the schedule is added.

Figure 2 is a schematic view showing the configuration of a simulation system for the evaluation of the schedule according to an embodiment of the present invention.

In FIG. 1, the input module 110 receives the data for the middle schedule plan, which is a simulation target, from the middle schedule database 15 of the middle schedule planning system 10 that establishes the middle schedule plan, and the simulation system 100 for the middle schedule evaluation. Processed according to the format that can be processed in the simulator module 130 and stored in the database module 140.

The user interface module 120 receives a request for a simulation of a middle schedule, which is a simulation target, from a user, and receives simulation input information and simulation option information.

In this case, the simulation input information and the simulation option information received from the user are stored in the database module 140 through the simulator module 130.

In this case, the simulation input information includes the number of the middle schedule plan to be simulated, the middle schedule start date by activity, the completion date of the middle schedule by task, and production resource information (working days, manpower, facilities), and the like. This includes the schedule selection, simulation condition, and result analysis condition information.

The simulator module 130 uses the simulation input information and the simulation option information input through the user interface module 120 to perform a simulation on the medium schedule plan, which is a simulation target authorized from the input module 110, and during the simulation. All generated data is stored in the database module 140.

As described above, the simulator module 130 includes a machining process, a small assembly process, an assembly process, a pre-design process, a pre-PE process, a pre-painting process, a BP1 process, a post-PE process, a BP2 process, a mounting process, included in a mid-schedule plan, Simulation is carried out for the trailing equipment process and the trailing paint process. Each process has a detailed model, and each model is distinguished by an industry code.

In addition, the simulator module 130 is different from the process and the type of work to be performed according to the panel or assembly block is injected and the order of execution is also different, the simulation is carried out by reflecting this when performing the simulation, some panels or assembly blocks are changed to each other Since the merge occurs, if the panel or block is combined when reflecting this, one representative panel or block is displayed.

The above-described simulator module 130 builds a work integration network through the work information registered for each line and the relationship information between the jobs, and then simulates the schedule schedule of all the ships based on this network.

Here, the work information for each ship includes a work code for each ship, a block name, a process and a work type, code information for a detailed work type, a start date and a completion date of a work, information of a work department and a unit workplace, and weight information, and the relationship between work Information is data that defines the relationships between jobs.

As shown in Fig. 3, there are three types of relationships between jobs, where the FS (Finish-Start) type is a case where a post-task is started after the predecessor is completed, and the FF (Finish-Finish) type is The successor task is launched later than the predecessor, but when it completes is the same as the predecessor and the successor task, in which case a job is journaled by more than one task, and the start-start type is predecessor. This is the case when and post-tasks are started at the same time. In this case, two or more tasks are combined into one task.

When the above-described simulator module 130 simulates the middle schedule plan based on the task integration network, the FS type waits for a block until the completion task start date after completion of the predecessor task. Because the post-task is journalized, the predecessor and the post-task are queued together until the start date of the next task in the post-task. In the SS type, the post-task only merges with the post-task when it finishes first, so only the post-task waits for blocks. Let's do it.

In addition, as shown in FIG. 4, the simulator module 130 performs simulation according to a task-based simulation method of performing simulation based on individual tasks. In the case of the FS type, the simulator module 130 has a margin between the preceding task and the following task. Since there may be a period, wait for the predecessor after the predecessor has been performed, and for the FF type and SS type, because the predecessor and the successor do not affect the simulation. It is recommended that the operation be terminated after only the operation of.

Meanwhile, the database module 140 stores simulation input information and simulation option information received from the user through the user interface module 120, and provides the input at the request of the simulator module 130. All data generated by the simulator module 130 is stored.

In addition, the database module 140 performs a function of providing the simulator results of the simulator module 130 to the middle schedule database 15 of the middle schedule planning system 10.

The output / analysis module 150 is performed by the simulator module 130 to output the data stored in the database module 140 so that the user can see it, and analyze the information required by the user.

Here, the output / analysis module 150 provides various types of information desired by the user, such as a graph, a maximum value, and a minimum value.

5 is a road showing an example of the screen provided by the input module of the present invention, the input module 110 provides an input window including a navigation button and the start simulation button, the user clicks the navigation button to schedule After selecting a middle schedule plan to be simulated among the middle schedule plans stored in the middle schedule database 15 of the planning system 10, and clicking the start simulation button, the data for the selected middle schedule plan is displayed in the middle schedule evaluation system. Processed according to the format that can be processed in 100 is stored in the database module 140.

6 is a road showing an example of a screen provided by a simulator module of the present invention, the simulator module 130 includes an start button, a stop button, and a reset button to provide an event controller window for adjusting a simulation. Click the button to run the simulation. Click the stop button to stop the simulation. Click the reset button to initialize the simulation and run the simulation again.

The time displayed in the event controller window described above is the start date of the first batch of tasks.

As described above, the simulator module 130 expresses one process as a large factory and expresses the detailed work as a lower factory to perform a simulation. In addition, the air field is represented before each business to express the work waiting to be put into each business, and the tasks of the middle schedule plan to be simulated are placed in each process and business based on the individual work according to the relationship type. Will be performed.

Meanwhile, as illustrated in FIGS. 7A and 7B, the output / analysis module 150 outputs, in real time, the amount of water waiting for the process and the work and the amount of work in progress as a graph while the simulation is performed. It is preferable. Here, the output reference is set to the number of blocks and weight to display the work unit of the work type to be able to grasp the real-time load change of the workplace.

8A and 8B are roads illustrating screens provided by the output / analysis module of the present invention. The output / analysis module 150 provides a result analysis window including a maximum / minimum navigation tab and a specific view navigation tab. The maximum and minimum navigation tabs are used to analyze the maximum and minimum values of workplace loads for a specific process and plant. After selecting a process and plant, set up all of the standby / workplaces, analytical criteria, work departments, and so on. If you click button, you can analyze the maximum / minimum time point and work list of the workplace.

On the other hand, the point-in-time navigation tab is used for load analysis of the workplace at a specific point in the simulation period. When the point-in-time, process and construction, standby / worksite, analysis criteria, work department, etc. are all set, click the navigation button. Analyze and provide load and work list information at a specific time in the workplace.
