Abstract

PURPOSE:To properly allocate the jobs to the workers in accordance with the individual worker's ability time, the working subjects, the working forms, the number of jobs, and the time required for picking up one of products, and the moving time of workers. CONSTITUTION:A controller 27 subtracts the moving time of a worker from his/her ability time obtained from a reference table 11 for ability time via an arithmetic unit 15 for four rules of arithmetic and defines the result of this subtraction as the real working time. Then the controller 27 obtains a subject coefficient and a working form coefficient for operations based on the working subject and the working form which are inputted to an input device 17 via a coefficient conversion table 23 for subjects and a coefficient table 21 for working forms. At the same time, the basic picking time of a product, i.e., the subject of work is obtained from a picking time table 19 for products. Then a picking content sallocating device 13 allocates the number of following products so that the working time does not exceed the real working time and at the same time is approximate to this real working time.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a work load leveling method for leveling out the work load among workers engaged in the logistics industry.

〔overview〕

The present invention is a work load leveling method for leveling the work load among workers engaged in the logistics industry, in which the ability of each worker is converted into ability time, and the work object and work form are converted into calculation coefficients. By subtracting the time required for travel and instructing each worker on the appropriate work content, it is possible to fairly allocate work to each worker and obtain the required work time and required personnel in advance. It is something to do.

[Conventional technology]

Traditionally, in the logistics industry, there was no concept of ability-based work instructions and basic work movements, so the assignment of work to each worker and the evaluation of each worker's work were based on the number of boxes carried by that worker and the time required for labor. It was simply calculated from the above, and did not take into account the abilities and proficiency of each worker, the object of work, work style, and travel time.

Conventionally, there has been no method for fairly allocating work to each worker and obtaining in advance the required work time and the required number of workers.

[Problem that the invention seeks to solve]

As mentioned above, in the past, there was a problem in that the assignment of work to each worker and the evaluation of each worker's work were simply calculated from the number of boxes carried by that worker and the time required for labor. .

Conventionally, in order to obtain the required work time and the required number of workers in advance, there has been a problem in that it is necessary to rely on the experience of people who know the work in detail.

Conventionally, the amount of work required for a shelf made up of one type of box as shown in Figure 2 (a) and a shelf made up of two or more types of boxes as shown in Figure 2 (6) In this respect, the load in Figure 2(b) is greater than in Figure 2(a), but
In the past, there was a problem in that work assignments were unfair because they were not differentiated.

Conventionally, if the number of boxes is equal between a shelf consisting only of large boxes as shown in Fig. 3(a) and a shelf consisting only of small boxes as shown in Fig. 3(b), Since it was assumed that the amount of work was the same, there was a problem in that work could not be allocated appropriately.

The problem is that the form of work is not taken into consideration when allocating work, for example, the work of transporting an entire box and the work of removing and transporting some products from the box are handled in the same way. was there.

SUMMARY OF THE INVENTION An object of the present invention is to provide a work load leveling method that allows work to be fairly allocated to each worker and the required work time and required personnel to be obtained in advance.

[Means for solving problems]

The present invention expresses the ability of each individual worker by ability time T,
The work object is represented by a coefficient p, the work form is represented by a coefficient q, the number of pieces to be worked is represented by n, the time to take out one piece is represented by τ, the moving time is represented by t, and T≧Z (p×
It is characterized by finding n/ (where n'≦n) such that qxn'xr)+:Et and allocating work to each worker.

Further, the present invention provides pXq for each work object and work type.
The present invention is characterized in that Xτ is stored and wiped in a database, the time for each moving location is stored in the database, the ability time T is given to each worker, and the above n' is determined by referring to the database.

[Effect]

``Ability of the person'', ``object of work'', ``work type'', and ``travel time'' are input, and the leveled content of the work is output as a result.

Leveling is to determine the number in the equation (2) so that the following equations (1) to (2) are satisfied.

■(Actual working time) - (Capacity time T) - (Traveling time Σt) ■ (Actual basic picking time) = (Basic picking time τ
) X (coefficient p related to work object) × (coefficient q related to work form) ■ (picking time) - (actual basic picking time) × (
(Number of pieces n') ■ (Actual working time) ≧ (Picking time 1) + (Picking time 2) ++ (Picking time n) Here, the capacity time T is the work that the target person can do during working hours. This is the time required for an average-level beginner to perform this task. Travel time is the total amount of time required for travel. The basic picking time τ is the time required to pick the box or one product under normal conditions. The coefficient p related to the work object is a coefficient determined from the size and configuration of the box that is the work object.

The coefficient q related to the work type is a coefficient determined by the work type, such as whether the whole box is carried or a part of the contents is taken out and carried. The number n' refers to the number of boxes or products, and determining this number is the core of the present invention.
