Work assistance device, work assistance method, and work assistance program

Abstract

An integer programming problem generation unit 38 acquires, from a production plan information DB 52, production plan information related to figure numbers for which setup work is yet to be performed,and formulates, as an integer programming problem, on the basis of the acquired production plan information, and predetermined restrictions, a problem for optimizing the execution order of the setupwork. An integer programming problem solver unit 40 uses GLPK or the like to determine the execution order of the setup work for each figure number. In this case, the integer programming problem generation unit 38 calculates, on the basis of the production plan information, a temporary setup work start time Si for each figure number of each mounter line, and, if the difference between Sj of figurenumber j and Si of figure number i which belongs to a different mounter line is equal to or greater than a threshold value DT, sets the setup order relationship between figure number i and figure number j to the order i->j. Accordingly, an appropriate execution order for the setup work can be determined with little computational complexity.

Description

technical field [0001] The present invention relates to a work assistance device, a work support method, and a work support program. Background technique [0002] In production lines such as surface mount lines and devices that perform various productions, the sooner the time (production completion time) assigned to each production line and device is completed in advance in terms of cost and delivery, the better. [0003] In the case of multi-variety and low-volume production in production lines and equipment, since the types of products (called "drawing numbers") change many times a day, it is necessary to change the settings of the production line and equipment each time (for example, , refer to Patent Documents 1 to 3, etc.). Such a setting change is called a "schedule", and a job for setting the change is called a "schedule job". During the scheduled work, production lines and devices are stopped. [0004] In many cases, one operator is in charge of scheduling work fo...

Problems solved by technology

[0009] In the optimization problem, since the number of production lines and devices increases, the number of combinations increases, so there is a possibility that the calculation will take a long time, or the combination may burst and cannot be calculated
