model, a firm can increase the product’s global quality by increasing the integrality of the product’s architecture. Higher … integrality, however, also increases the degree of interaction between the two components’ designs, making coordination between … invests more to reduce engineers’ turnover rate. A lower turnover rate, in turn, increases the integrality of the product …

Universally balanced combinatorial optimization games

Demange, Gabrielle; Deng, Xiaotie - In: Games 1 (2010) 3, pp. 299-316

This article surveys studies on universally balanced properties of cooperative games defined in a succinct form. In particular, we focus on combinatorial optimization games in which the values to coalitions are defined through linear optimization programs, possibly combinatorial, that is subject...

The Power of Integrality: Linkages between Product Architecture, Innovation, and Industry Structure

Fixson, Sebastian K.; Park, Jin-Kyu - Sloan School of Management, Massachusetts Institute of … - 2007

A substantial literature stream suggests that many products are becoming more modular over time, and that this development is often associated with a change in industry structure towards higher degrees of specialization. These developments can have strong implications for an industryÂ€Ù³...
