Managers of research and development (R&D) programs are often confronted with questions of what determines R&D spending (i.e. R&D search intensity) and when R&D spending is unprofitable (i.e. Reservation Technology Level). Three determinants of R&D spending are identified: the current technology...

The efficient operation of a beef cattle feedlot is governed by the purchase and selling weights and prices of the animals and by the feeding system used. The optimal feeding system will involve feeding least cost rations to animals at every stage in the production process. A method is described...

In many computer applications messages of various lengths need to be stored in some storage device. In this paper we examine the problem in which a fixed number of record lengths can be used to store messages. Whenever a message arrives, it is stored in the smallest possible record which is at...

We consider the problem of selecting capacity additions from a finite set of possible facility sizes to meet demand at a single location over an infinite horizon. The problem is motivated and illustrated by an application to the planning for the deployment of long haul transmission facilities in...

A heuristic algorithm employing dynamic programming is presented for solving the two-dimensional cutting stock problem where all the small rectangles are of the same dimensions, but without the usual restriction that the cutting be done with "guillotine" cuts, i.e., cut which must be made in...
