We investigate the fixed, sample-size, batch-mean procedure for creating confidence intervals from simulated data obtained from a stochastic queueing system with multiple customer classes. We show that, for a multiclass M/M/1 queue, serial correlation between customers of the same class...

In this study, we analyze firms’ membership in R&D (Research and Development) cooperation networks. Our main research hypothesis is that the membership in cooperation networks is related to the degree of the knowledge spillover. The approach focus on both cost symmetry and cost asymmetry. For...

A mathematical model is presented which incorporates many descriptive characteristics of decentralized R&D resource allocation processes. In general it is a member of the class of models referred to as decision process models. In specific it is representative of an R&D resource allocation...
