SOLUTION: When multiple work is conducted at multiple places for the road work requiring lane control and traffic control, the master information such as work places, types of work, and work conditions is inputted to the server (computer) 1 of a management center, and the order of priority is stored. Input terminals 2 such as keyboards at the work places A, B, C are connected to the server 1 via communication circuits, and exceptional information and emergency information can be inputted. The computer of the server 1 controls schedules based on these information and displays the corrected schedules on output devices such as printers, CRTs, and liquid crystal displays at the work places A, B, C. The schedule control work can be simplified.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a work adjusting system, and more particularly to a work adjusting system for adjusting a schedule of a plurality of works accompanied by regulation of road facilities, railway facilities and the like.

[0002]

2. Description of the Related Art
When performing work such as road construction and road / rail repair work, lane restrictions and road closures are often implemented to ensure safety. In some cases, it may be more convenient to perform a plurality of tasks at the same place at the same time, but some tasks cannot be performed in the same time zone. For example, in the same location on a two-lane road on one side, if one work needs to control one lane and another work needs to control the other lane, traffic is impaired. Since it is possible, it cannot be done in the same time zone.

Further, there are cases where work cannot be performed due to exceptional events such as weather conditions and special events, and there are cases where other work cannot be performed unless a certain work is performed first. Conventionally, schedule management such as construction and equipment inspection is usually done by 1
The work schedule was created on a monthly basis, the desired dates and times for each work were entered in the table, and the work was adjusted while comparing and examining the presence or absence of competing work, the priority of work, and the presence or absence of exceptional events.

FIG. 11 shows a schematic view of a conventional work schedule adjustment flow. First, a list of operations that each company handles for one month is made into a list and submitted to the manager who adjusts the operations (step S101). Next, the administrator classifies the submitted work according to date and time and place (step S10).
2).

With respect to the divided work, the characteristics such as the importance of the work, the time taken, the possibility of simultaneous work with other work, etc. are judged (step S103). It is determined whether or not the work needs to be stopped due to an exceptional event such as weather conditions or traffic of an important vehicle (step S104). Based on the results of the above classification and judgment, the work is prioritized and the work that needs readjustment is extracted (step S105). The work that needs re-adjustment is a work that has been removed from schedule management, and it is necessary to determine the schedule again.

In step S106, if there is no work requiring re-adjustment, the schedule adjustment ends, but if not, the person in charge is notified of the work requiring re-adjustment by telephone or FAX, and the list is re-displayed. Request for submission (step S107). Conventionally, the above procedure
It was repeated until there was no work to readjust.

However, the construction and inspection are carried out by a large number of different types of contractors, and in the list submitted in step S101, only the work for which they are in charge is entered for each contractor, and other contractors are in charge. The current situation is that the working situation is not known at all. Skilled managers perform the classification and judgment after step S102, but the actual work on a monthly basis may amount to several hundreds, and this judgment takes a huge amount of time.

Further, preparation of a list, mailing, telephone contact,
Since work such as re-filling the list is also done manually, it usually took several days to complete the schedule adjustment. For example, there are 10 contractors outsourced work,
If there are 100 jobs each in a month, it takes 2 days for the contractor to submit the list and collect it in the hands of the management person, 5 days for the work classification, and the work characteristics and exceptional events. It took 3 days for the judgment, 2 days for the prioritization of the work, 2 days for the extraction of the work requiring adjustment, and 2 days for the notification of the re-submission of the list, a total of about 12 days.

[0009] In particular, when it is necessary to have skill in judging work classification and work characteristics, and when there are dozens of adjustment works, the adjustment work is complicated and the burden on the person making the classification and judgment is considerable. It was great. In addition, even if a skilled worker performs work adjustment, the confirmed work schedule may not always be a work-efficient schedule. Further, among these dozens of types of work, there are some in which the priority order of work is decided, and in many cases work that can proceed at the same time is known in advance.

Therefore, the present invention has been made in consideration of the above circumstances, and avoids redundant work from the list of submitted work requests, shortens the time for work adjustment, and improves efficiency. The present invention provides a work adjustment system that enables the creation of an effective work schedule.

[0011]

According to the present invention, an input means for inputting work information, a first storage means for storing a priority order of a plurality of works, and a work condition including information on the possibility of simultaneous work are stored. Second storage means, duplicated work extraction means for extracting a plurality of temporally and positionally duplicated works from the work information, and work extracted by the duplicated work extraction means according to the work condition and the priority order. And a duplication avoiding means for avoiding duplication, the duplication avoiding means determines the work having a high priority when it is determined that there is a duplication of work that cannot be performed simultaneously by referring to the work conditions. The present invention provides a work adjustment system characterized by selection.

The present invention further comprises a second input means for inputting an exceptional event affecting the performance of the work and the priority of the exceptional event, and an output means, wherein the duplicate work extracting means uses the exception information from the work information. The work that overlaps with the event temporally and positionally is extracted, and when the extracted work has a lower priority than the exception event, the duplication avoiding means does not confirm the extracted work and re-enters it. The output means may output the extracted work for prompting.

A pointing device such as a keyboard or a mouse can be used as the input means for inputting the work information and the second input means for inputting the exception information. The first storage means and the second storage means are RAMs.
It is preferable to use a rewritable storage element or medium such as

The work information input by the input means is information about the work to be adjusted, and the work name,
The work date, work place, etc. are included. The priority order stored in the first storage means is generally represented by a numeral. For example, a number "1" is given to the highest priority, and a larger integer is given as the priority becomes lower.

The working conditions stored in the second storage means are:
For example, whether a certain work can be carried out simultaneously with other work, whether a certain work is accompanied by special restrictions, and a certain work can be carried out only after satisfying predetermined conditions. Means characteristics and implementation conditions. It is preferable to store the above-mentioned priority order and working conditions in the RAM or the like before the actual adjustment.

The duplication work extraction means and the duplication avoidance means are usually composed mainly of a CPU, ROM, RAM, timer and I / O.
It is composed of a so-called microcomputer including an interface and the like. Further, in order to realize the function of each of these means, a program for executing work adjustment is stored in the ROM.
Alternatively, it is provided on the RAM. The output means means, for example, a printing device such as a printer or a display device such as a CRT or a liquid crystal display.

It is also possible to provide an input device including an input means for inputting work information separately from a device including other means and dispose the input device at a remote place. In this case,
The communication means may be provided in both the input device and the device including other means, and both may be connected by a communication line. Here, it is preferable that the input device includes a keyboard. The communication line used at this time is a dedicated line,

BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be described in detail below based on the embodiments shown in the drawings. Note that the present invention is not limited to this. FIG. 1 is a block diagram showing an embodiment of the work adjusting system of the present invention. This system is composed of a server 1 placed in a management center where work adjustment is performed, and a plurality of input terminals 2 for inputting work content and date and time.

Here, the server 1 is a computer such as a workstation or a personal computer, and comprises a keyboard, a display, a storage device, a communication device and the like.
The input terminal 2 is also composed of a workstation or the like. The input terminal 2 is arranged in the business office of each trader who actually performs the work and is usually away from the management center, so that the server 1 and the input terminal 2 are connected by a communication line. Depending on the scale of this work adjustment system, a dedicated line, ISDN line, analog telephone line, or the like is used for this communication line.

Each trader inputs request information about work to be performed in a certain month using his / her own input terminal 2 by a predetermined day of the previous month. For example, work request information as shown in FIG. 2 is input. The main request information entered here is
The work contents, work place, work date, start time, end time, and the like performed by the trader. Usually, each trader inputs these work request information without considering the work contents of other traders. Further, in FIG. 2, it is shown that lane regulation is necessary when performing the inspection work of the road traffic information board, and the characteristic values (lane regulation, priority order, etc.) necessary for the work are also input.

When such work request information is input from the input terminal 2, the input terminal 2 adds the identification information of the trader and creates transfer data. Then, the transfer data is transmitted from the input terminal 2 to the server 1 via the communication line and stored in the storage device in the server 1. In addition to such work request information, the server 1 stores master information necessary for work adjustment. The master information includes “road position information”, “work type” to be targeted, “work condition”, “priority order” of work, “exceptional event”, “possibility of simultaneous work”, and the like.

Here, "road position information" means a prefectural road,
It is the distinction of city roads, road numbers and names, and the distance between major points on the road. The “road position information” is used when determining whether the work places of the input request information are the same place, or how far the places of a plurality of works are.

"Type of work" means the name of work carried out by a contractor, for example, "rejuvenation work", "emergency repair work", "regular repair work", "new installation work", "equipment inspection".
and so on. In addition, the type of work (construction name),
It is preferable that the priority and the information about the possibility of simultaneous work are given to each and stored in the server 1. This work name, priority, and information about the possibility of simultaneous work are collectively stored and called a "work master", and one example thereof is shown in FIG. If work of the same priority is duplicated in the same place, the coordinator of the management center shall decide the work to be adopted.

The "working condition" of the master information is
It means the conditions to be considered when adjusting the work schedule. For example, "work A and work B cannot be performed at the same place at the same time", "work A requires lane regulation", "work C cannot be performed when the weather is rainy", "in different lanes on the same road" 2 or more work with lane regulation cannot be done within the same time zone within 2km before and after. "," When work B and work D are performed at the same place, work D must be prioritized. " The work condition “cannot be done afterwards” is stored in the server 1 in advance. These “work conditions” are conditions that the manager in charge of the management center has empirically found necessary or conditions to be satisfied for each individual work, and are input at the management center before work adjustment.

The "exception event" in the master information is
Although it is not the work itself, it is a factor that has an important influence on the work adjustment and is an event that must be taken into consideration at the work adjustment stage. A specific example of this exceptional event is shown in FIG. For example, when an event such as a VIP traffic of an important vehicle occurs, the construction is suspended for a predetermined time period. Also, special events such as marathons and parades, the existence of special police requests, deterioration of weather forecasts, and excess workforce can be one of the exceptions. As these “exception events”, in addition to the priority order, the date and time, the place, and the work content as shown in FIG. 5 are input in advance by the management center side and stored in the server 1 as the “exception event master”.

When the work having the same priority and the exceptional event are duplicated at the same place and at the same time zone, the exceptional event is prioritized and the duplicated work is once removed from the schedule in order to readjust it. Further, when two or more works having the same priority order are duplicated at the same place and at the same time zone, the works other than the work adopted by the coordinator are once removed from the schedule. The work that was missed from the schedule
It may be stored as a readjustment list in the server 1 and notified to the input terminals 2 of the respective companies in charge as readjustment work via a communication line.

FIG. 6 shows a specific example in which simultaneous work is impossible. The shaded area in the figure indicates the construction section including the lane regulation section. Although the lanes of the road traffic information board and the road illumination lights (points A and B) are different on the same road, the distance between both construction sections is within 1 km. Also, because the construction time zones overlap partially, if you do it at the same time,
Altered lanes may be dangerous and may lead to severe traffic congestion.

FIG. 7 shows a concrete example in which the work is impossible. This concrete example shows a case where an exceptional event of holding an international conference occurs. In this case, since an international conference is held within a predetermined period and important vehicles pass through a predetermined place, the inspection work of the road traffic information board is missed from the schedule.

Next, the flow of work adjustment performed in the server 1 will be described. The work adjustment is performed by extracting a duplicate work from the input request information of each supplier and repeating a series of processes of determining the possibility of duplicate work, determining the priority of the work, and determining whether there is an exceptional event. Done. When performing this determination processing, the server 1 described above
The work master, the exception event master, and the work condition stored in advance are referred to. By performing such work adjustment processing, it is possible to perform classification and determination processing in a few hours, which conventionally required several days, and shorten the overall processing of work adjustment.

FIG. 8 shows a flow chart of the work adjustment of the present invention. In step S1, each trader inputs work contents from the input terminal 2. In step S2, the work contents are input until all the works in one month unit by the trader are completed. At this point, all the input work content data is transferred to the storage device in the server 1 via the communication line. The above is the processing on the input terminal 2 side.

In step S3, after the work content data has been transferred, the server 1 sets the date to be processed to "1". The work content data transferred to the server 1 includes a work place, a work day, a start time and an end time. In step S4, it is determined whether or not there is overlapping work at the same place and at the same time zone by searching for data of all work contents having the same date.

For example, in the specific example shown in FIG. 6, the two works have the same date of December 05, and the work time zones partially overlap. Further, from the position information stored in the server 1, it can be seen that the point A on the △△ line and the point B on the △△ line are the sections where the construction section can be within 1 km. Can be considered to be. Therefore, in this case, it is determined that there is duplicate work at the same place and at the same time zone.

In step S4, if there is no overlapping work, the process proceeds to step S13, 1 is added to the date, and the process returns to step S4 to enter the work adjustment of the next day.

In step S5, when there is an overlapping work, it is determined whether the works can be performed at the same time.
Here, the work conditions described above are referred to. For example,
In the case of the specific example of FIG. 6, the work condition that “two or more works involving lane regulation in different lanes on the same road cannot be performed within the same time zone within 2 km before and after” is satisfied. Therefore, in the specific example of FIG. 6, it is determined that the two requested works cannot be performed at the same time, and the process proceeds to step S6. If the duplicate work is possible, the process proceeds to step S8.

In step S6, it is determined which of the duplicated works should be prioritized. Here, the priority information stored in advance in the work master is used. For example, in the specific example of FIG. 6, the overlapping work is “inspection work” and “repair work”, but according to the work master shown in FIG. 3, the order of the regular repair work (repair work) is 3, The order of equipment inspection (inspection work) is 5.
Therefore, since "repair work" has a higher priority than "inspection work", "repair work" is selected. Also,
The work other than the selected work is descheduled and pooled in the readjustment list in step S7.

FIG. 9 shows a concrete example of work adjustment. FIG.
Is a specific example in the case where two works compete at the same place and at the same time zone. “Regular repair work” with high priority is adopted, and “new work” is pooled in the readjustment list.

Next, in step S8, it is determined whether or not an exceptional event exists at the same place and at the same time zone. Here, the exception event master described above is referenced. If there is an exception event corresponding to the exception event master, the priority order of this exception event and the work selected in step S6 is compared and determined in step S9. Then, the higher priority is selected, but when the work selected in step S6 is removed, the work is pooled in the readjustment list (step S10). In the concrete example of FIG.
Since there is no exceptional event, the process proceeds to step S12.

FIG. 10 is a concrete example of the case where the work and the exceptional event compete at the same place and at the same time zone. Since both have the same priority, the exceptional event "important vehicle traffic" is prioritized, “Rejuvenation work” will be pooled in the readjustment list.

In step S11, it is determined whether or not the date of interest is the end of the month. If it is the end of the month, the process proceeds to step S12, and if it is not the end of the month, step S13.
Proceed to. In step S12, the work pooled in the readjustment list in step S7 and step S10 is displayed on the display screen of the server 1 to instruct that re-input is necessary. At this time, the re-inputtable time zone may be displayed.

Further, the fact that the re-input is necessary and the reason and the re-inputtable time zone may be transferred to the input terminal 2 of the trader who performs the work pooled in the readjustment list. By doing so, it is possible to greatly reduce the time and labor required for mailing a document for notifying that readjustment is necessary, telephone call, fax instruction, and the like. Furthermore, since the notification is made by data communication, it is possible to make the notification more reliably.

In the specific example shown in FIG. 6, the “road traffic information board inspection work” is a pooled work, but the input supplier name, work place, date and time, contents, etc. of this inspection work are displayed on the display screen of the server. Then, the free time zone that can be re-entered is displayed. Similar contents are also displayed on the input terminal 2 of the trader who performs the inspection work. The input terminal of the trader may sound an alarm sound in order to notify the person in charge of the trader that the re-input notification as described above has been given.

Upon receipt of the re-input notification, the trader may make internal adjustments as necessary and input a desired time slot from the notified free time slots. The re-input desired time zone is transferred to the server 1, and the adjustment is tried again according to the work adjustment flow shown in FIG. If the adjustment work described above is performed until all the work requested by the contractor is assigned to the schedule, the schedule adjustment of the work for one month is completed.

Since the information transmitted and received between the input terminal 2 of each trader and the server 1 is about several hundred bytes at most, the information transfer is completed within several seconds. Further, although a plurality of input terminals 2 are connected to one server 1, if a computer having a so-called workstation class processing capacity is used as a server, steps S3 and below shown in FIG. The work adjustment process can be performed in about tens of minutes.

Therefore, it can be considered that the new input and the re-adjustment input of the work contents on the input terminal 2 side by manpower take the most time, but the whole work adjustment including the manpower input is about one day. If you can complete it. That is, the examination time of each contractor at the work planning stage before inputting the requested work requires substantially the same procedure and time as before, but at the stage of adjusting all work, it takes 10 days or more for the conventional work adjustment. The time spent can be reduced to 1/10 or less by using the work adjusting system of the present invention.

As described above, the conditions for prioritizing the work to be adjusted and the possibility of simultaneous work are set in advance, the work with the higher priority is selected preferentially, and the duplicate work that is not selected is selected. Avoids duplication by prompting re-entry, so the time required for work adjustment can be dramatically reduced. Further, since an exceptional event that is not directly related to the work but has an influence is set in advance, it is possible to improve the work adjustment accuracy and create an efficient work schedule.

Further, even when a sudden exceptional event occurs after the work adjustment, the work adjusting system of the present invention can flexibly and swiftly respond. The work adjustment system of the present invention can be used in a system that monitors equipment that needs to perform a large number of restricted works. In addition to the road equipment monitoring system shown in the above-described embodiment, a railway and an airport can be used. It can be used in equipment monitoring systems for energy, energy, and buildings.

[0047]

According to the present invention, the work adjustment time can be shortened because the redundant work is avoided in accordance with the work condition stored in the storage means and the priority order. Further, since an exceptional event that affects the performance of the work is input and the work overlapping with the exceptional event is avoided according to the priority order, an efficient work schedule can be created.
