制約緩和によるロット編成システム

This paper discusses the solution method for a lot making problem. The developed system makes automatic lot making possible by using a constraint relaxation method for order specification and delivery time under the recent situation that are diversification of product types and decrease in order size. This constraint relaxation is realized by developing a rule interpretation function. This constraint relaxation method for lot making problem is useful in having the following functions.
(1) Setting of lot making constrains to meet management goals
(2) Ease of setting constrains for even non-experts in lot making
(3) Robustness to change of product types
Applying the system to the actual plant can reduce lot making time and improve delivery time.
