It states that the Tax Reform Act of 1969 altered the nature of tax switching by forcing banks to report both gains and losses on transactions in government and corporate bonds as ordinary income rather than as capital gains. It presents major demand factors that contribute...

The just-in-time (JIT) system has been studied extensively and implemented by a number of US firms as an ell'ective production system. The core of JIT involves determination of lot size and setup time reduction so as to increase manufacturing flexibility while minimizing the inventory level. This decision problem usually involves multiple conflicting objectives and mixed-model production. In this paper, goal programming (GP) is applied to a real-world JIT problem involving fabrication of differe...

One of the most difficult tasks of state highway patrol administrators is allocation of manpower; i.e. determining the most effective level of operational manpower for patrol tasks. Typically, administrators resolve the allocation problem by relying on prior statistical data and by employing subjective analysis. In general, only limited systematic analyses have been applied to the problem. The paper presents an integer goal programming model for allocating highway patrolmen to road segments with...

The location-allocation problem involves multiple shipping destinations, with known demands for a given product and known transportation costs from sources to destinations. The problem is to determine the number of facilities and their locations in order to best service the shipping destinations. This paper presents an approach to facility location which allows the analysis of multiple conflicting goals as an extension of previous solution approaches. Specifically, the paper applies the branch a...

Virtually all models developed for transportation problems have focused upon the optimization of a single objective criterion, namely the minimization of total transportation costs. They have generally neglected or often ignored the multiple conflicting objectives involved in the problem, the priority structure of these objectives, various environmental constraints, unique organizational values of the firm, and bureaucratic decision structures. However, in reality these are important factors whi...

Rule induction is aimed at finding stable dependences in data. The approaches to rule induction can be roughly divided into two groups: data-driven and model-driven. Although the majority of induction techniques used in data mining are data driven, implementing some elements of the model-driven approach may be useful in domains where comprehensive prior knowledge exists. This paper illustrates that use of information about ordinal scales for some o...

Many classification tasks can be viewed as ordinal. Use of numeric information usually provides possibilities for more powerful analysis than ordinal data. On the other hand, ordinal data allows more powerful analysis if compared to nominal data. It is therefore important not to overlook knowledge about ordinal dependencies in data sets used in data mining. This paper investigates data mining support available from ordinal data. The effect of cons...

This meta-analysis (114 studies, k = 157, N = 21,616) examined the relationship between self-efficacy and work-related performance. Results of the primary meta-analysis indicated a significant weighted average correlation between self-efficacy and work-related performance, G(r±) = .38, and a significant within-group heterogeneity of individual correlations. To account for this variation, the authors conducted a 2-level theory-driven moderator analysis by partitioning the k sample of correla...

Most educational software packages for management science/operations research (MS/OR) introduced in the 1980s were designed mainly to obtain model solutions efficiently. As an effective teaching (or learning) aid, MS/OR software should be designed as a drill and practice program to encourage the student's participation in solving a model. It should also provide clear explanations of the solution procedure. Consequently, educational MS/OR software should adopt a solution algorithm that can help ...

Multiattribute decision making involves tradeoffs among alternative performances over multiple attributes. The accuracy of performance measures are usually assumed to be accurate. Most multiattribute models also assume given values for the relative importance of weights for attributes. However, there is usually some uncertainty involved in both of these model inputs. Outranking multiattribute methods have always provided fuzzy input for performance scores. Many analysts...

Over the last two decades before 1987, Korea has achieved a truly remarkable economic growth. After the World War II, Korea was one of the world's poorest countries, heavily dependent on agriculture and financially dependent upon the U.S. foreign aid. Since 1961, however, with strong political leading, sound economic planning, and hard work on the part of Korean people, Korea has overcome its lack of natural resources and achieved a real annual growth rate of over 9% in GNP. Exports, which reach...

Korea has achieved remarkable economic growth over the last twenty-five years. The strong leadership and sound economic planning of the government were important elements of this growth. However, perhaps the most important driving force behind Korea's economic success has been a group of large business conglomerates, referred to as Chaebols. The economic and political power of these Chaebols is enormous. The total sales of the top five Chaebols exceeds 50% of Korea's GNP, while the total exports...

Multiple attribute decision making is important in many decision making contexts where tradeoffs are involved. The use of qualitative input has proven especially attractive, allowing subjective inputs to be used. However, such systems inherently involve uncertainty with respect to parameter inputs, especially when multiple decision makers are involved. This paper presents the method of grey related analysis to this problem, using interval fuzzy numbers. ...

The decomposition algorithm has received increasing attention in recent years not only as a computational technique for large-scale management models but also as a systematic tool for designing organizational structure and information systems in decentralized organizations. The Kornai-Liptak (1965) decomposition algorithm is effective in providing important managerial implications from the solution. However, the major deficiency of the technique is a wide fluctuation of solutions in its converge...

This essay draws from the emerging positive psychology movement and the author’s recent articles on the need for and meaning of a positive approach to organizational behavior.

Organizations that can effectively combine TQM and ...

This paper considers the transfer batch scheduling problem for a two-stage flowshop with identical parallel machines at each stage. Two cases of separable and inseparable setup times and processing times are examined. A scheduling rule similar to Johnson's rule is suggested to minimize makespan. The scheduling method developed in this paper subsumes many existing methods for two-stage flowshop makespan minimization. A numerical example is presented to illustrate the scheduling method.

Albania is a country with many unique characteristics. It is the last country in Europe to escape from the communist system and also still the poorest nation in Europe.
