Description

[0001] The present invention relates to a project scheduling system and method,

The present invention relates to a project schedule schedule, and more particularly, to a project scheduling system that enables a production planner in a shipbuilding industry to establish a system schedule (equipment installation) It is about the method.

In general, shipbuilders will start business design according to the type of vessels (merchant ships, special ships, etc.) and size (displacement), and also establish a large-scale schedule in the production plan to dry the ship or offshore structure . Once the sales design is established, detailed design will be made, and the purchase schedule will be established, and then a mid-term plan will be established to work with the purchase schedule.

Once the above detailed design and middle planning is established, production planning necessary for production is made again, and small schedules necessary for production are established by department and type of work, and then purchase materials and perform production. Of course, in this case, the production scheduling and the production plan are set up separately, and the manpower arrangement, the dock layout, the work place arrangement, the drying facility schedule adjustment, and the subcontractor schedule control are interlocked in the ship building schedule.

As described above, the production characteristic of the shipbuilding industry is that when ordering stock is ordered, the design is carried out simultaneously with the production, and the equipment and the related system equipment to be assembled according to the drying schedule have a process of being put in stock (or completed).

On the other hand, in establishing the schedule, the Project Master Schedule will be established in which the dock is constructed in the form of a boat and then the chairman works or installs the system. At this time, schedule of system installation and inspection should be established together with schedule of project. The system is typically installed during the design work of ships or offshore systems, and most of the design work is planned on a zoned basis. In other words, project scheduling establishes a schedule through a single schedule chart at the center of the zone, and forces the system information to be inserted into the schedule chart of each zone to establish the project schedule.

A conventional technique for establishing a production schedule in shipbuilding is disclosed in Korean Patent Laid-Open Publication No. 10-2005-0082895 (published on Aug. 24, 2005).

In the prior art disclosed in the patent literature, when establishing the production plan of a ship, the process steps such as assembling and mounting and the supporting processes such as processing and design are separated from each other, and the main production plan and the supporting production plan So that the stage of the production plan can be reduced and the accuracy of the plan can be improved.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a project scheduling system and method according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram of a project scheduling system according to a preferred embodiment of the present invention. The legacy database 10, the node generating unit 20, the data providing unit 30, the system installation activity activity generation unit 40, an inspection activity generation unit 50, a project master schedule database (PMS DB) 60, and a project schedule management unit 70.

Here, the legacy database 10, the node generating unit 20, and the data providing unit 30 refer to an in-house database system as a legacy system. The system installation activity generation unit 40, the inspection activity generation unit 50, the project master schedule database (PMS DB) 60, and the project schedule management unit 70 become one activity generation apparatus. The user (designer) interacts with the activity generating device to receive a necessary schedule chart and utilize it.

The legacy system and the activity generation device are located remotely from each other, and interface data through a specific communication interface. At this time, communication interfaces may be various, and communication interfaces such as normal Ethernet and TCP / IP may be used.

The legacy database 10 stores information related to installation and inspection of a system installed in a zone of a ship to be dried. Here, the term "system" refers to equipment installed in a specific area.

When the information request for installation and inspection of the system occurs from the project scheduling management unit 70, the node generating unit 20 generates a joint point, which is a point capable of managing the activity of the system in cooperation with the legacy database 10 And provides it to the project schedule management unit 70. Here, the activity means schedule-type information having information for scheduling.

The data providing unit 30 provides system installation and inspection data corresponding to the nodes generated in conjunction with the node generating unit 20. Here, since the system installation and inspection schedule are established in units of zones during the ship drying, it is preferable that the data providing unit 30 also provide system installation and inspection data corresponding to the nodes classified by the zone.

The system installation activity generation unit 40 processes the system installation data provided by the data providing unit 30 into a system installation activity form capable of scheduling and transmits the system installation data to the project schedule management unit 70.

The inspection activity generation unit 50 processes the inspection data provided by the data providing unit 30 into an inspection activity form capable of establishing an inspection schedule and transmits the inspection data to the project schedule management unit 70.

The project schedule management unit 70 receives a node through the node generating unit 20 and maps the system installation activity and the inspection activity to the received node and outputs the project activity to the project master schedule database (PMS DB) And provides a schedule chart and a master schedule chart based on the information when the user's plan request is generated. That is, the project schedule management unit 70 divides a specific zone into nodes, and stores the project master schedule information by mapping the system and the inspection schedule activities installed in the specific zone to node units.

The operation of the project schedule scheduling system according to the present invention will be described in detail as follows.

First, when the boat is completed in the dock at the time of ship construction, the system is installed in each zone by the next step, and the installed system is inspected. In this case, since ships are usually completed in units of zones and are combined with each other, it is desirable to establish a system plan for each zone and establish a schedule.

In order to set up and check the system, and to establish a project master schedule (PMS) for simultaneously planning the zone and the system, the user requests the schedule scheduling management unit 70 for scheduling. In response to the request, the project schedule management unit 70 provides a schedule chart and a master schedule chart based on the system installation activity and the inspection activity from the project master schedule database 60.

In order to provide the schedule chart and the master schedule chart, the system installation activity and the inspection activity should be generated. In order to do this, the legacy system is requested to interwork with the legacy system and generate information for the system installation and inspection activity. At this time, data is transmitted and received between the project schedule management unit 70 and the legacy system through a communication interface. The communication interface can use Ethernet or TCP / IP well known in the related art. In addition to these communication interfaces, various communication interfaces already known may be used.

When a request for system installation and inspection information occurs, the node generator 20 of the legacy system extracts system installation data and inspection data for a specific zone in cooperation with the legacy database 10, which is an in-house database. Here, it is assumed that the legacy database 10 stores system installation data and inspection data for an arbitrary area of the vessel in advance. Then, a node, which is a point where a specific zone is divided and an activity to be generated can be managed, is transmitted to the project scheduling management unit 70 through the communication interface. In addition, the extracted system installation data and inspection data are transmitted to the data providing unit 30. The data providing unit 30 transfers the system installation data for the specific zone to the system system installation activity generating unit 40 through the communication interface and transmits the inspection data to the inspection activity generating unit 50.

The system installation activity generation unit 40 processes the system installation data provided by the data providing unit 30 into a system installation activity form capable of schedule planning and transmits the processed data to the project schedule management unit 70. In addition, the inspection activity generation unit 50 processes the inspection data provided by the data providing unit 30 into an inspection activity form capable of establishing an inspection schedule and transmits the inspection data to the project schedule management unit 70. The check here means to confirm that the system is installed in the proper location.

The project schedule management unit 70 receives a node through the node generating unit 20 and maps the system installation activity and the inspection activity to the received node and outputs the project activity to the project master schedule database (PMS DB) . That is, the project schedule management unit 70 divides a specific zone into nodes, and stores the project master schedule information by mapping the system and the inspection schedule activities installed in the specific zone to node units.

Then, according to the planning request of the user, the scheduling chart and the master schedule chart are generated and provided based on the received node, the system installation activity and the inspection activity.

Here, the schedule chart is a chart for a zone, as shown in FIG. 2, which shows the schedule of a zone as a drying block unit in scheduling of a ship, and a system chart as shown in FIG. 3 showing schedule information of a specific equipment . Such a section-dedicated chart or system-dedicated chart is the same as the section-dedicated chart and the system-dedicated chart that are created for establishing the system in the area and the area when the schedule of the existing ship is established, and a detailed description thereof will be omitted.

As described above, when a zone and a system are established by a single schedule, there is a disadvantage that a schedule is not taken into account in consideration of production, installation and inspection schedules because the relation to the zone and the system is not considered. Since marine systems are typically intricately intertwined in many areas, planning independently of the area and system presents many problems. In addition, when the zone and system schedule are independently established as described above, there is a problem that the user must forcibly insert the system information into a single schedule chart of the zone unit to establish a plan.

Therefore, for the convenience of such inconvenience and schedule planning, the present invention also provides a system / region mixed chart as shown in FIG. 4 in which the zone specific chart and the system specific chart are mixed in the schedule chart. Here, the system / zone mixed chart is a chart that simultaneously displays the zone schedule and the system schedule via one chart. As shown in FIG. 4, the system / zone mixture chart is repeatedly displayed in the multiple zones if the system activities installed in the multiple zones are the same. The user (planner) can efficiently plan both the area and the system by using this system / zone mixture chart. In addition, if the zone and system installation schedule are implemented as a single chart, it is possible to check whether there is interference between the workers or what the preceding job is, which makes it easier to judge the work situation.

5, the master schedule chart includes a calendar area 81, a key event area 82, a header area 82, An area 83, and an activity area 84 where activity information is displayed.

In the calendar area 81, the smallest one column is designated as a week on a calendar day basis, so that the overall chart schedule is compressed and displayed. The key event area 82 is implemented so that the line and row key events are represented and are not duplicated in the same row in order to improve readability. The header area 83 is for dividing the area into large / medium / small areas, and the activity area 84 represents all the activities defined by the user. Herein, the activity area 84 includes an activity summary information area 85 for displaying the area where the system installation is completed as a central management item. That is, the user can designate a green route for the summarized activity information, which becomes the activity summary information area 85. [ That is, the activity summary information is expressed in the designated zone unit.

FIG. 6 is a flowchart showing a project schedule scheduling method according to the present invention. In FIG. 6, S represents a process of providing project scheduling in software in the project schedule scheduling management unit 70 in FIG.

As shown in FIG. 6, the project scheduling method according to the present invention includes: (a) requesting installation and inspection information of a system to be installed in a zone on a legacy side, (S10 to S20); (b) processing (S30 to S40) the system installation and inspection data into a system installation activity and an inspection activity form capable of schedule planning; (c) mapping the system installation activity and the inspection activity to the node and storing the mapping in the project master schedule database (S50); (d) generating a schedule chart and a master schedule chart based on the node, the system installation activity, and the inspection activity when the planning request is generated, and providing (S60 to S70).

The project scheduling method according to the present invention will be described as follows.

First, when the boat is completed in the dock at the time of ship construction, the system is installed in each zone by the next step, and the installed system is inspected. In this case, since ships are usually completed in units of zones and are combined with each other, it is desirable to establish a system plan for each zone and establish a schedule.

In order to set up and check the system, and to establish a project master schedule (PMS) for simultaneously planning the zone and the system, the user requests the schedule scheduling management unit 70 for scheduling. In response to the request, the project schedule management unit 70 provides a schedule chart and a master schedule chart in step S10. In order to provide the schedule chart and the master schedule chart, the following procedure is required.

That is, in step S10, the legacy system is requested to interwork with the legacy system to generate the system installation and inspection activity. At this time, data is transmitted and received between the project schedule management unit 70 and the legacy system through a communication interface. The communication interface can use Ethernet or TCP / IP well known in the related art.

In the legacy system, when a system installation and inspection information request is made, system installation data and inspection data for a specific area are extracted in association with the legacy database 10, which is an in-house database. A node is created by dividing a specific area and managing a generated activity, and transmits the node to the project schedule management unit 70 through the communication interface.

In step S20, the project schedule management unit 70 receives the zone node and the system installation and inspection data, and processes the system installation data received in step S30 into a system installation activity form capable of scheduling. Then, the inspection data received in step S40 is processed into an inspection activity form capable of establishing an inspection schedule.

In step S50, the project schedule management unit 70 maps the system installation activity and the inspection activity to the received node and stores the system installation activity and the inspection activity in the project master schedule database (PMS DB) 60. That is, the project schedule management unit 70 divides a specific zone into nodes, and stores the project master schedule information by mapping the system and the inspection schedule activities installed in the specific zone to node units.

Thereafter, when a user's plan request is generated as in step S60, a schedule chart and a master schedule chart are generated based on the nodes stored in the project master schedule database 60, the corresponding system installation activities and the inspection activities in step S70 And provide them.

Here, the schedule chart is a chart for a zone, as shown in FIG. 2, which shows the schedule of a zone as a drying block unit in scheduling of a ship, and a system chart as shown in FIG. 3 showing schedule information of a specific equipment .

As described above, when a zone and a system are established by a single schedule, there is a disadvantage that a schedule is not taken into account in consideration of production, installation and inspection schedules because the relation to the zone and the system is not considered. Since marine systems are typically intricately intertwined in many areas, planning independently of the area and system presents many problems. In addition, when the zone and system schedule are independently established as described above, there is a problem that the user must forcibly insert the system information into a single schedule chart of the zone unit to establish a plan.

Therefore, for the convenience of such inconvenience and schedule planning, the present invention also provides a system / region mixed chart as shown in FIG. 4 in which the zone specific chart and the system specific chart are mixed in the schedule chart. Here, the system / zone mixed chart is a chart that simultaneously displays the zone schedule and the system schedule via one chart. As shown in FIG. 4, the system / zone mixture chart is repeatedly displayed in the multiple zones if the system activities installed in the multiple zones are the same. The user (planner) can efficiently plan both the area and the system by using this system / zone mixture chart. In addition, if the zone and system installation schedule are implemented as a single chart, it is possible to check whether there is interference between the workers or what the preceding job is, which makes it easier to judge the work situation.

5, the master schedule chart includes a calendar area 81, a key event area 82, a header area 82, An area 83, and an activity area 84 where activity information is displayed.

In the calendar area 81, the smallest one column is designated as a week on a calendar day basis, so that the overall chart schedule is compressed and displayed. The key event area 82 is implemented so that the line and row key events are represented and are not duplicated in the same row in order to improve readability. The header area 83 is for dividing the area into large / medium / small areas, and the activity area 84 represents all the activities defined by the user. Herein, the activity area 84 includes an activity summary information area 85 for displaying the area where the system installation is completed as a central management item. That is, the user can designate a green route for the summarized activity information, which becomes the activity summary information area 85. [ That is, the activity summary information is expressed in the designated zone unit.

As described above, the present invention provides a project schedule chart considering the zone and the system at the same time, so that the user (planner) establishes an accurate and reasonable schedule using the schedule chart linked with the zone and the system.

Although the present invention has been described in detail with reference to the above embodiments, it is needless to say that the present invention is not limited to the above-described embodiments, and various modifications may be made without departing from the spirit of the present invention.

The present invention is applied to a technique for establishing a project master schedule in the shipbuilding industry. In particular, it provides a schedule chart that links the system with the area, so that it can be used for all industries that manufacture structures in marine structures and block units as well as ships.
