Abstract

A system is provided for the preparation of a cyclic maintenance work schedule table. The system includes a display unit which can show boxes defined by dates in a desired period and the names of individual workers. The system also has a worker data memory for storing scheduled work information of the individual workers during the period and work qualifications of the individual workers; a building data memory for storing the names, work details, last working dates, and contracted frequencies of maintenance work of buildings to be worked with during the period; a processor for deciding working dates in the period for the buildings stored in the building data memory; and another processor for allocating the names of the buildings in the descending order of the difficulty of work items on the basis of data - which have been obtained from the worker data memory, building data memory and working date deciding means - and, after one of the boxes has been filled with a predetermined working time, moving to another one of the boxes.

Claims

1. A cyclic maintenance work schedule table preparation computerized system retained by a contractor having concluded a contract with persons owning or managing buildings to have workers conduct maintenance of equipment installed in the buildings, said system having a display unit for showing thereon boxes wherein dates in a desired period, the names of individuals workers, and the names of the buildings allocated to the boxes to allocate the individual workers to the contracted buildings are displayed, said system comprising:

worker data memory means for storing scheduled work information of the individual workers during the period and work qualifications of the individual workers as to whether they can perform a two-man maintenance job or a one-man maintenance job;

building data memory means for storing the building names work details including whether each job is a two-man maintenance job or a one-man maintenance job, last working dates, and contracted frequencies of maintenance work of building to be worked during the period;

first means for computing the remaining working time of each worker in each box allocated with one or more buildings;

second means for computing working dates in the period for non-scheduled buildings whose working dates have not yet been designated, on the basis of the contracted frequencies of maintenance work stored in the building data memory means;

first means for allocating the buildings, whose working dates have been designated, to boxes of qualified workers on the designated working dates;

second means for allocating the names of two-man job buildings out of the non-scheduled building to the boxes on the basis of the data of the worker data memory means, the data of the building data memory means, and results from the said first and said second means for computing and, when the remaining working time of the workers whose names were allocated to the boxes becomes insufficient, the remaining two-man job buildings are allocated to other boxes; and

third means for subsequently allocating to boxes the names of one-man job buildings out of the non-scheduled buildings on the basis of the data of the worker data memory means, the data of the building memory means, results of said first and said second computing means, and when the remaining working time of the workers in these boxes becomes, insufficient, the remaining one-man job buildings are allocated to unallocated boxes.

2. A cyclic maintenance work schedule table preparation system according to claim 1, wherein each of the designated buildings has been designated not only in working date but also in worker or workers.

3. A cyclic maintenance work schedule table preparation system according to claim 2, wherein said second allocating means first allocates each designated building to the box of the designated worker or workers on the designated date.

4. A cyclic maintenance work schedule table preparation system according to claim 1, wherein said second computing means takes into consideration the frequencies of maintenance work and the last working dates.

5. A cyclic maintenance work schedule table preparation system according to claim 1, wherein said first computing means computes, with respect to each worker to whom the names of at least one building has been allocated, the remaining working time from the working time schedule for the allocated working date and the working time of the worker in a day.

6. A method for the preparation of a cyclic maintenance work schedule table on a cyclic maintenance work schedule table preparation computerized system, said system having a display unit capable of showing thereon boxes wherein dates in a desired period, the names of individual workers and the names of the buildings allocated to the boxes so that a contractor having concluded a contract with persons owning or managing buildings to have workers conduct maintenance of equipment installed in the buildings can allocate the individual workers to the contracted buildings, said method comprising the steps of:

providing a worker data memory for storing scheduled work information of the individual workers during the period and work qualifications of the individual workers as to whether they can perform a two-man maintenance job or a one-man maintenance job in;

providing a building data memory for storing the names work details as to whether each maintenance work is a two-man job or a one-man job, last working dates, designated working dates and contracted frequencies of maintenance work of building to be worked during the period;

reading from the building data memory at least one designated building whose scheduled maintenance work date has been designated and allocating the building so read to the box of at least one appropriate worker on said work date;

computing the remaining working time of each worker in each box allocated with a building;

computing working dates of the non-scheduled buildings on the basis of the last working dates and the contracted frequencies of maintenance work stored in the building data memory;

reading the names of two-man job buildings from the building data memory and allocating the two-man job buildings to boxes on dates permitting the maintenance work of the buildings, in which boxes the designated buildings have been allocated and working time still remains;

allocating remaining two-man job building to boxes on dates permitting maintenance work, in which boxes working time still remains;

computing the remaining working time of the boxes to which the two-man jobs have been allocated as described above;

reading one-man job buildings from the building data memory and allocating the one-man job buildings to boxes on date permitting the maintenance work of the buildings, in which boxes buildings have already been allocated and working time still remains; and

allocating remaining one-man job buildings to boxes on dates permitting maintenance work, in which boxes working time still remains.
