An Analysis on Make-or-Buy Decision Making in Serial Production System

MATSUKAWA Hiroaki

17th International Conference on Production Economics pro-Prints (Innsbruck, Austria) ,

2012.02

Oral presentation (general)

We construct a make-or-buy decision-making model for a serial manufacturing system considering internal making cost and external purchasing cost. Internal making cost consists of fixed cost and variable cost, while external purchasing cost is exhaustively determined by outside supplier. Since decision-making in previous stage affects decision-making in successive stage, the model becomes quite complicated. In this paper, we introduce a binary switching variable to each production process so that to control material flow in the manufacturing system, consequently have a solution to the make-or-buy decision making observing the value of the switching variables. We prove some characteristics of the model associated with the switching variable, and develop an easy algorithm to find optimal solution.

AN ANALYSIS OF MML AGENT SIMULATION UNDER UNIFORM DISTRIBUTION OF GAIN PARAMETER

Oral presentation (general), Asian Association of Management Science and Application

We often use uniform distribution to describe diversity of agent values. And
this description often used in agent simulation which mimics real society on
computer what which we call an artificial society. In this paper we show
that, an agent simulation under uniform distribution may cause wide
divergence of final convergent consensus points, though we give a fixed
initial macro consensus value to an artificial society facing an alternative
decision. Because intuitive observation provides a same convergent value of
final consensus for a given initial value of macro consensus, we call this
uncertainty or divergence of the final consensus the pitfall of agent
simulation. Through numerous simulations, we found that the divergent final
consensus have some order %and follows zeta distribution, and the mechanism
of the uncertainty were unveiled in this paper.

VOCとロバスト性を考慮した多目的同時最適化モデルの提案

MATSUKAWA Hiroaki

日本経営工学会平成23年度秋季研究大会 (盛岡、日本) ,

2011.11

Oral presentation (general)

より良い製品企画からスムーズな生産移行に至るまでの過程において，顧客の声(VOC:Voice Of Customer)の反映，技術開発などによるロバスト性の確保，技術アイデアを再利用した企画，そして企画から販売・廃棄にいたる製品ライフサイクルの全フェーズに関連する部門が、企画や開発設計などの段階に参加・協働するCEの採用など，これらの原則を統合した新製品開発は生産者側にとって必要不可欠である．そこで本研究では，新製品の設計変数を，VOCとロバスト性という2つの視点からバランスのとれたパラメータ設計が可能になるように，多目的計画法を用いてQFDとタグチメソッドを統合し，それをさらに生産段階まで拡張を行う．

需要予測モデルの実用化における問題点

MATSUKAWA Hiroaki

日本経営工学会平成23年度春季研究大会 (名古屋、日本) ,

Oral presentation (general), 日本経営工学会

需要予測は難しい．その理由はいろいろあるが，本質的には激しい競争を通じて人工的に形成された複雑で不確実は市場が原因である．ものが足りなかった昔，衣食住行の商品予測は比較的に単純で，例えば1つの家庭において1年のおコメの消費量は正確に予測することができた．従って，全国のお米の消費量の予測も同程度の精度で予測することができた．
