About this issue

AFTER a concentrated dose of “operations research” and “economic” type of papers in the March issue (a special issue containing selected papers on R&D Management from the 1966 Military Operations Research Symposium), the papers in this issue again discuss a variety of topics related to the management of R, D, & E. This variety does, however, contain two papers — those by Ledley et al. and by Hulbert and Scalera — related to the theme of the March issue. This theme contains the pervasive questions in activities such as Research, Development, and Engineering: how much should we spend and how shall we allocate the available funds among various opportunities? Many papers in this Transactions over the past seven years have been concerned with such questions. Since useful and general answers are not yet in sight, this theme will continue to be explored in future articles.
