Abstract

PURPOSE:To obtain the system for generating and changing automatically a lead time and a standard time by collecting an actual result value in a job site of the lead time and the standard time required for a day's schedule plan and heaped management of a subsystem of a production control system and fetching it into the system summing it up automatically, and calculating the maximum value, an average value and the minimum value. CONSTITUTION:The standard time and a lead time are generated and changed automatically by adding newly an actual result value editing part 6, an actual result editing information selecting part 7, an actual result information file 8 and an actual result information collecting part 9, to a conventional process developing part 2, a heap developing part 1, a reference day's schedule file 3, and a reference information registering part 4. Up to the present, the standard time and the lead time are inputted from a terminal machine by executing a calculation by a time measuring or WF method of a product flowing in an actual job site, therefore, excessive time is required and also, the standard time is changed frequently and time is required for its correction. Since such a measurement and a calculation are unnecessary, the time taken therefor can be shortened remarkably.

Description

Detailed Description of the Invention

[0001]

[Industrial application field] Data for calculating lead time and standard time required for schedule management and pile management, which are subsystems of the production management system in the manufacturing industry, are data for calculating the start date, completion date, number of units, and required The present invention relates to a system for importing actual values such as man-hours and defective units into a system, and automatically creating a lead time of a standard schedule file for schedule management and progress management, and a standard time for pile management.

[0002]

2. Description of the Related Art The lead time used for schedule management and the standard time used for pile management also change when the standard time changes. The standard time changes frequently due to product design changes, operator familiarity, equipment deterioration, and site improvements. Conventional standard time is calculated by actually measuring the actual processing time by machine type, work process, number of units, or by the WF method, and lead time is measured by the non-processing time (transportation, stagnation time) and the processing time of the equipment. , Calculated and determined the total time from order receipt to shipment within the factory. Table 1 shows the details of the lead time.

[0003]

[Table 1]

It takes a very long time to actually measure the above-mentioned time with a product flowing in the field and determine it for each machine type and work process. When design changes, rationalization of worksites, and work changes frequently occur, they are measured each time and the database changes are input over time.

[0005]

[Problems to be Solved by the Invention] Regarding the setting of lead time and standard time for each model and work process, which are indispensable for the system operation of schedule management and pile management, products that have been used in actual sites Since the processing time and non-processing time of (1) are actually measured and determined by the stopwatch, there are skilled measurement personnel, and the measurement also takes time. It also takes time to input it into the database file of each system. The present invention is for eliminating the time of time measurement and input.

[0006]

[Means for Solving the Problems] In order to eliminate the measurement time of the machining time and the non-machining time, and the lead time obtained from them, and the input time to the system database of the standard time,
Key-in from the POP or terminal from the POP or terminal without measuring or calculating the standard time and lead time as in the past, but the number of products actually flowed in the field, the number of units according to the work process, required man-hours, defective units, defect countermeasure time, etc. Etc. will be stored in the performance collection file of this new system at regular intervals. The lead time and standard time are obtained by calculating and tabulating these data from the once / month result file in the same model and the same work process in the result value editing section.

[0007]

[Function] In the conventional system for performing schedule management, progress management, and pile management, a reference value information registration unit for registering standard time and lead time, a reference schedule file to be filed, a model type,
Generally, there is a process procedure development unit for each work process and a mountain development unit for performing a process-specific pile. In the present invention, a performance information collection unit that collects performance values at the site, a performance information file that files the performance results, and a performance value editing unit that calculates and totals the performance values are newly added, and the performance values are stored in the POP or terminal on the site. When input from the machine, the file is automatically calculated and the data of the conventional standard schedule file is updated, and the standard time and the lead time are automatically changed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is an example of a conventional computer system principle block diagram of reference schedule registration, files, and process procedures. From the display terminal 5 for inputting standard values, input processing such as machine type (by product number), process, number of units, work center, load status information, etc. is executed, and the detailed information of the entered schedule is stored in the reference schedule file 3. Is stored. In the standard schedule file, in addition to the detailed information of the standard information registration unit 4, the Gantt chart of the standard schedule of each model as shown in FIG. Detailed information such as piles of each process is also stored.

Conventionally, the actual time is actually measured at the site, or the standard time calculated by the WF method or the lead time from the order reception to the product shipment is input from the display 5 of the reference value input, and is generated in the process procedure developing unit. The lead time is input to the reference schedule for each model and process, and the Gantt chart of each reference schedule for each model and process is stored in the reference schedule file. Further, the piles by department generated by the pile developing unit are also stored in the standard schedule file.

However, the standard time is frequently changed on an everyday basis in extreme cases due to design changes, habituation of workers, aging of mechanical equipment, rationalization of work sites, improvement of work and the like. If the standard time changes, the lead time also changes. Therefore, if the standard time is measured or calculated by the WF method as in the conventional case, it takes a lot of time, and a lot of man-hours are required to input the standard time. The present invention solves these problems.

FIG. 4 is an example of a block diagram of the computer system principle of the present invention. It has a display 5 for inputting reference values similar to the conventional one, a reference information registration unit 4, a reference schedule file 3, a process procedure development unit 2, and a mountain development unit 1, and inputs the standard time and lead time of the results of the present invention. A display or POP terminal device 10 for inputting information, a performance information collecting unit 9 for collecting those data, and those data for each model,
Achievement information file 8 that is filed by process and number of units, or the actual value edit unit 6 that extracts the data of the same model or similar model from the actual file and calculates the three values of maximum, average, and minimum, which of the three values It is composed of the achievement edit information selection display 7 which determines whether to use.

Embodiments of the present invention will be described below with reference to the drawings. First, regarding the standard time, data such as the number of parts per process, the number of processes, the time required for machining, the defect correction time, the number of defective units, and the lead time are the start date and the completion date of each process for each model. , Or input from the display 10 of the terminal at regular intervals (hourly or daily), it is stored in the performance information file 8 from the performance information collecting unit 9. The stored data is extracted from the performance information file 8 on a monthly basis, and the performance value collection unit 6 calculates the standard time for each part and each operation. Next, the standard time is calculated for each part, work, and lead time for each of the same model and similar models, and three values of the maximum value, the average value, and the minimum value are calculated, and those three values are calculated in the display of the performance edit information selection 7. You can change it monthly if you decide which one to use, or if you specify any of the three values, it will continue every month and it will be stored in the reference schedule file and generated by the process procedure development unit 2. The lead time of the Gantt chart of the schedule is automatically changed, and the standard time of the process-specific pile generated in the pile developing unit is automatically changed.

When the lead time is determined in a factory where many products are ordered in the same manner, the lead time of the process-specific result for each product number is input as performance information and stored in the performance information file 8. From the file once a month, the lead time code for each withdrawal process is the same or similar in the actual value editing unit 6 and the lead time code is added to the same and stored in the reference schedule file as the reference schedule. The lead time will be decided if the lead time code is added to the product number and arranged from the next month.
