ABSTRACTThe author reviewed the conceptual, methodological, and empirical problems associated with across‐individual tests of expectancy theory predictions of work behavior. Based on the literature it was hypothesized that within‐individual expectancy theory predictions would be superior to across‐individual predictions. Using a sample of 159 college students, results were generally supportive: mean across‐individual and mean within‐individual correlations were r=.24 and r=.35, respectively. Also, in light of the widespread use of incremental (marginal) decision algorithms in various disciplines, it was hypothesized that a return on effort (ROE) predictor would yield better correlations than the conventional maximum expected benefits predictor. As hypothesized, correlations using the ROE predictor consistently exceeded correlations using the maximum expected benefits predictor in both the across‐ and within‐individual paradigms r=.27 versus r=.18, and r=.52 versus r=.35,

ABSTRACTAlthough the diffusion and transmission of cyclical impulses are basic characteristics of economic and business activities, traditional studies of business cycles do not provide an effective measure of cyclical interaction. The purpose of this paper is to use spectral analysis to determine the cyclical patterns of multivariate economic and business time series. The proposed methodology was applied to the regional industrial diversification problem.

摘要:

ABSTRACTAs a result of the passage of the Occupational Safety and Health Act of 1970, many employers are confronted with a multiple decision situation. The employer would like to comply with federally imposed standards as quickly as possible, but the employer must consider the budgetary limits under which he can profitably operate while achieving compliance. A goal programming model can be formulated to solve the problem. In this paper a review of the OSHA requirements is made, and a case example is presented to demonstrate the applicability of goal programming to resolving the budgetary pressure of OSHA compliance.

摘要:

ABSTRACTThis paper reports on a simulation study which was undertaken to determine if float could be significantly reduced by altering a bank's check‐processing priority assignments. Float, the dollar value of check payments not yet collected from parent banks, represents a significant opportunity cost in terms of lost interest income to receiving banks. The study consisted of a comparison of a major city bank's present checksorting decision rules based on minimization of check handling, versus a proposed sorting scheme based on dollar magnitudes of checks. The reults of the research indicated that float could be substantially reduced and interest income increased by employing the proposed priority of scheduting rule

摘要:

ABSTRACTThis paper formulates a multi‐period course scheduling problem as a zero‐one programming model. Under various constraints, and for a planning horizon of several terms, the model seeks to maximize: (1) the faculty course preferences in assigning faculty members to courses, and (2) the faculty time preferences in allocating courses to time blocks,viaa two‐stage optimization procedure. The multi‐period structure of the model, strengthened by the explicit inclusion of a wide‐range of constraints designed to represent various special requirements has enabled the model to capture the many dynamic features of the course scheduling problem at the college level. As such, it can be used not only for long‐range or short‐range departmental planning, but also as a suitable framework toward the development of a larger, and all‐inclusive course scheduling decision system. The paper begins with a brief review of several related studies and then presents a multi‐period scheduling model and its extensions. Some numerical examples are used to test the model, and the authors' experience, resulting from such tests with several computer codes, is reported. The possible directions for future research a

摘要:

ABSTRACTIn this paper the results of an extensive simulation study are reported to provide empirical evidence on the Evaluation and Bound approach. Some rules for implementing the procedure interactively on a computer are also examined and compared experimentally. The results suggest that the Evaluation and Bound procedure, in conjunction with an appropriate strategy of implementing it, would reduce considerably the information requirement of the decision maker in the choice of a preferred multiattribute alternative.

摘要:

ABSTRACTThis paper illustrates how multivariate spectral analysis can be used to analyze complex, dynamic, business systems. Important temporal aspects of multiple time series are captured in the frequency domain by the coherence, phase, and gain statistics. A computer simulation of a time domain model produces sample results which demonstrate how the timing relations between two series can be reversed when the effects common to both series are partialled out. Finally, an empirical multivariate analysis of beef prices is used to determine the timing relations among prices at different levels of the production‐distribution syste

ABSTRACTThe author discusses the well known (by faculty) but seldom articulated (to students) mathematical reason that the simple EOQ model can be optimized by equating total, rather than marginal, costs.

摘要:

ABSTRACTThis note discusses a theoretical peculiarity about the interrelationships between the sample size and the two types of decision errors in hypothesis testing theory. It is shown that for a given decision rule, while the alpha error invariably diminishes as the sample size becomes larger, the beta error could increase for certain values of the parameter under the alternative hypothesis.
