Market environment surrounding enterprises and various organizations is globalized ever faster and very fluid. Establishment of sustainable competitive advantage is sought for every organization to develop, survive and adapt in such managerial circumstances. Innovation is one of useful managerial principle. In this paper, the applicability of Actor-Network Theory (ANT) as an analytical viewpoint to innovation studies was discussed. ANT is a prime example of the Socio-Technical approach. First, precedent innovation studies were surveyed and current streams of the studies were confirmed. Then, precedent innovation studies applied ANT were surveyed and the differences between them were clarified. From these differences, the usefulness and applicability of ANT as an analytical viewpoint to innovation studies were concluded. One of reasons is, ANT analyzes innovation from not the viewpoint of reductionism but the viewpoint of relationship. Furthermore, the viewpoint of ANT has an affinity for the viewpoint of innovation studies in general management studies, especially the viewpoint that focuses on process and network. Starting on the study of innovation using ANT, it will have the complexity that all things are treated as variables without the assumption that something is constant tacitly. However it has the possibility to discuss the innovation topic from the difference views and to derive some unique results. Lastly, two issues for innovation studies using ANT were brought.

地域暖房の熱輸送システムの設計計画問題において, (イ)配線系サイズの縮小化, (ロ)ポンプ規模の縮小化および(ハ)熱交換器系サイズの縮小化という設計目標をそれぞれ独立した目的関数として考え, 一つの非線形多目的最適化問題として定式化した. 上記問題に対し, 計算機を対話形式で援用してシステム構成機器の主要設計要目を合理的に決定する一手法を提案し, 設計事例を通じてその有効性の検証と最適解の特徴を検討した.

This paper describes a strategy for foreign direct investment (FDI) of multinational enterprises when manufacturing costs change with time. This FDI planning problem is formulated in order to determine how many manufacturing facilities are needed in each country when they are needed, and how many products should be manufactured to meet the product demand in each country. It is assumed that both product demand and manufacturing costs in each country change with time. Finally, an algorithm for finding an optimal solution of the FDI planning problem is developed and an example is demonstrated.
