A simple mathematical model describing the diffusion of a new, infrequently purchased product is proposed. Many previous papers have reported that the differing behaviour of quot;innovatorsquot; and quot;imitatorsquot; is fundamental to the diffusion process. However, previous models have failed...

Key Features:Helps readers build an in-depth understanding of design reuse and its support to product development and product family designPresents a holistic model to integrate a variety of design reuse issuesOffers methods and aids to assist low-cost, high-performance product design for...

Use of common parts for different products (commonality) is important methods for managing product variety and preserving competitiveness in the age of mass customization and supply chain competition. In literature, the advantages of inclusion of common components in a product family are well...

This paper demonstrates the sensitivity of the linear programming approach in the estimation of productivity measures in the primal framework. Specifically, the sensitivity to the number of constraints (level of dis-aggregation) and imposition of returns to scale constraints is evaluated....

Previous research on optimal R&D subsidies has focussed on the long run. This paper characterizes the optimal time path of R&D subsidization in a semi-endogenous growth model, by exploiting a recently developed numerical method. Starting from the steady state under current R&D subsidization in...
