ABSTRACTThe problem of scheduling jobs onM‐parallel processors is one of selecting a set of jobs to be processed from a set of available jobs in order to maximize profit. This problem is examined and a dynamic programming solution is presented which decomposes it into a sequencing problem within an allocation problem. The computation required for solution is found to depend on the sequencing problem as it is affected by the waiting cost function. Various forms of the waiting cost function are considered. The solution procedure is illustrated by an example, and possible extensions of the formulation are discusse

摘要:

ABSTRACTA computer simulation experiment was conducted to evaluate and compare seven individual item forecasting models across five different demand patterns. Results indicate the best model varies depending upon the demand pattern, the time period forecast, the noise level of the demand pattern, and to a lesser extent the measure of forecast error. Across all demand patterns, exponential double smoothing was best for the long run forecast and at least second best for the short run regardless of noise level in the demand patterns. Analysis of modelswithina demand pattern yielded, in most cases, several models as ranking equally well. The adaptive model developed here did not perform as well as some other models. For example, it ranked no better than third on a step function demand pattern.

摘要:

ABSTRACTThe paper illustrates the desirability and feasibility of the computer simulation technique in socio‐psychological research. A computer simulation model of a five‐man industrial work group is constructed. After the model has successfully passed a two stage validation procedure, an experimentation phase is conducted. In a 2 times 3 replicated factorial experiment, five years of simulated weekly data is used to test several hypotheses which relate the independent variables–supervisory style and worker interpersonal orientation–to productivity, worker job satisfaction and group cohesiveness. The hypotheses were derived from the findings of prior short‐lived laboratory and field research. The study indicates that the computer simulation approach is a valuable adjunct to the classical organizational research t

摘要:

ABSTRACTThis paper describes the application of a linear programming model to the process of resource allocation at Illinois State University. The model developed is a general model designed to assist academic administrators in allocating the scarce resources at their disposal. The model, and the assumptions upon which it is based, may be altered to suit the particular decision criteria of any particular academic institution.The linear programming model developed here maximizes an objective function which reflects the total net social profit realized by the university on its outputs to society. This objective function was maximized subject to a myriad of constraints which reflected the limitations of budget, space, and other scarce inputs. Further, the constraints reflect the joint interdependency of many parts of the university and the particular educational delivery system employed by a given department. The outputs of the model include the optimal mixture of academic outputs by the university, the optimal distribution and usage of inputs inside the university, and the shadow price of each input.While the linear programming model developed here is general and may be applied to any university, it was applied to Illinois State University in this paper. In the case of Illinois State University, the model recommended a substantial reduction in emphasis upon teacher education.

摘要:

ABSTRACTIn an experiment, thirty‐six professional insurance men employed the utility method, the worry method, and the comparison method in two insurance problems to determine the appropriate insurance coverage. It was found that the best act with the utility method almost always was no insurance, whereas the best act with the other two methods tended to be complete insurance. The utility method best act rarely agreed with the subject's actual preferred act, while the comparison method best act usually was the same or almost the same as the actual preferred act. While the worry method suggests that the subjects typically are risk averse, the utility functions obtained tend to show that the subjects typically are not risk avers

ABSTRACTThis paper gives an example of how to structure a set of lectures on eigenvalues and eigenvectors for students of economics, finance, or any of the other decision sciences. It is presented in a fairly self‐contained style, suitable for the relative beginner, but its main purpose is to present the instructor with a way to motivate definitions and tie key concepts togethe

摘要:

ABSTRACTThe evaluation of the effectiveness of faculty teaching is a difficult process. This paper presents the results of an experimental empirical investigation into the possibility of using a psycho‐linguistic measurement technique, the Semantic Differential, to measure faculty communication of terminology to students. This measurement could be used to supplement other teaching evaluation devices. The paper determines a set of “key concepts,” derives a set of S.D. meanings from a Faculty to act as a standard, and measures student meanings at the beginning and end of an introductory course. These sets of meanings are then com
