摘要:

AbstractThis paper describes a method for computations in linear programming which is midway between methods such as the “stepping stone” procedure for the distribution model in which no inverses of bases are kept, and the modified simplex method in which one carries along the complete inverse of the basis at each stage. It is designed to avoid division by pivots until the optimum basis has been obtained. Thus a small pivot will not affect adversely all subsequent st

摘要:

AbstractThis paper presents a detailed discussion of an economic model for the surveillance of a production process; it also presents optimal policies for making inspections of and adjustments to the process, which is characterized by a tendency to deteriorate after each adjustment. Some of the conclusions are for general processes, and, on the other hand, the more specific results are for Poisson processes.

摘要:

AbstractAn operational simulation is a collection of interrelating events. In order to code a simulation more easily for an electronic computer the events should be isolated, i.e., free from immediate interactions. Logical aid is used to determine cause‐effect relationships and eliminate impossible interactions from consideration. A timing model is set up, partitioning the events in time and space finely enough to insure their mutual exclusiveness. An automatic computer program is described that will compile mutually exclusive events, which may all be precoded as if occurring at one time and at one place. The program allows flexibility for adding, omitting, and replacing events or their parts, and for interrupting the simulation to allow human decisions to be incorporate

摘要:

AbstractIn this paper, the queuing problem characterised by Poisson arrivals and a wide class of service time distribution has been solved by applying the phase method under the condition of limited waiting space. This problem is already solved by Finch, but he gave only explicit solution for the case of exponential distribution. The phase method has an advantage of giving the solution in a form which is easily computable. Tables are presented for the operational parameters for exponential and 2‐Erlang service time distribution

摘要:

AbstractThis paper deals with the analytical study of the encounter of fighter interceptors with the incoming formation of an air task force of enemy bombers. An attempt is made to frame a stochastic model of the situation and to determine the probabilities of hit under different conditions. It is indicated that with reasonable estimates of the operational parameters involved the various probabilities are capable of optimization.

摘要:

AbstractIn this paper a stochastic model for an air defense problem has been developed, in which it is assumed that the time during which the formation of enemy bombers is in free‐state and in contact‐state follows general distributions, and the probability of hits follows a Poisson proc
