A DSS approach for implementing an online retail banking system: A case study

This article is based on the author's experience in supervising the development and implementation of a distributed online retail banking decision support system (DSS) for Arab National Bank (ANB) in Riyadh - Saudi Arabia. The system emphasizes the different components and characteristics of DSS in terms of flexibility, responsiveness, ease of use, interactive interface, and the use of an adaptive process for design and implementation. The system provides branch management with facilities for direct control and monitoring of branch operations and for immediate access to information needed for decision making. Customer service was drastically reduced from an average of 30 minutes per transaction to a one minute average. The prototyping approach made it possible to solicit user participation and to facilitate the training and conversion processes which in turn eased the way for smooth and successful implementation.

Bank branch operating efficiency: A comparative application of DEA and the loglinear model

In this paper, a comparison regarding the operational efficiency of individual branches of a bank is made, through the application to the same body of data of two different estimation methods: (i) Data Envelopment Analysis (DEA) and (ii) Loglinear Model Analysis. In addition to that, the study examines whether operations in the bank branches were conducted in regions of increasing, constant or decreasing returns to scale. The DEA results suggest that increasing, constant or decreasing returns to scale may be observed in different regions of the production function, whereas the Loglinear model suggests that increasing returns to scale are in operation.

The effect of employing advanced branching mechanisms in superscalar processors

This paper discusses the effect of employing advanced branching mechanisms in superscalar processors. The motivation behind employing advanced branching mechanisms in superscalar processors is to reduce the control dependence, or in other words the number of branch operations, in the program so that instruction-level parallelism can be exploited more effectively. The second effect achieved by reducing the control dependence in the program is a decrease of the amount of branch penalty due to less branch operations. In this paper, two advanced branching mechanisms are discussed. The first mechanism involves incorporating multiple condition registers in superscalar processors. The second mechanism is a novel multi-way branching scheme proposed in this paper. A quantitative analysis on the effect of the two branching mechanisms shows that incorporating multiple condition registers can boost the superscalar processor performance by a factor of 16% to 20% while employing the proposed multi-way branching mechanism can achieve even greater performance improvement, up to 47%.

An efficient three-point arc algorithm

For many applications a 2-D circular arc can be conveniently specified by three points that lie on the arc. Since the radius of curvature grows without bound as the three points become collinear, any practical algorithm must avoid calculating the arc's radius or functions of the radius. An algorithm that achieves this objective is presented. It is very efficient because it uses exclusively integer arithmetic and requires only addition, subtraction, comparison, and branch operation in the inner loop. >

Strings on hyperelliptic supersurfaces

Starting from a definition of a hyperelliptic superRiemann surface (HESS), we study its supermoduli space and the “superVirasoro” algebra on it. We map that algebra into a Z 4 p=2 parafermionic algebra on CP 1,1. Using explicitly supersymmetric bosonization of the first-order superconformal systems, we construct explicitly the primary fields of the parafermionic algebra: the branching and the spin operators. We give a simple prescription for the calculation of sdet D γ on HESS through correlation functions of these branching operators. As an example, we calculate the g = 2 superstring partition function and verify that the cosmological constant vanishes, after integration over the moduli space.

Mathematical modeling of hydraulic regimes in the transition between the surge tank and conduits of a hydroelectric station

1. The introduction into design practice of computer calculations of transients led, on one hand, to an increase of possibilities for analyzing various operating regimes of surge tanks, including those which investigators have lost sight of, and, on the other hand, required considerable expansion of the volume of data characterizing the operation of conduits, branches, and local resistances. 2. The developed method permits analytic determination of the relationship between the specific energies of flows in the fork of a tank in the complete range of its operating regimes. In this case two values of the resistance coefficient are used, one of which is determined with respect to the regime of the entry of the total flow from the diversion into the tank and the second with respect to the entry of the total flow from the tank into the diversion. 3. As a result of analyzing Soviet and foreign data of investigations of the hydraulics of forks [3, 4, 5] it was established that the resistance coefficient of a transition between a tank and conduits is composed of a constant component which depends on the geometry of the transition and a variable component determined by the relationship of discharges in the branches. 4. The use of the proposed analytic relations in calculating transitions on a computer increase the quality of modeling and reliability of the results obtained.

The temporal logic of branching time

A temporal logic is defined which contains both linear and branching operators. The underlying model is the tree of all possible computations. The following metatheoretical results are proven: 1) an exponential decision procedure for satisfiability; 2) a finite model property; 3) the completeness of an axiomatization.

A structured APL preprocessor

This paper presents a set of structured control statements for APL and a preprocessor to implement them. The preprocessor translates structured APL functions into APL functions using the branch operator to replace the structured statements. The translation is based on finding keywords, such as IF and WHILE, appearing in syntactically valid places in the function. Since no modification of either the APL interpreter or APL syntax is required, the APL editor can be used to modify structured functions. The preprocesor also produces an indented listing that aids in the debugging of programs.

Erisa.

In my opinion, the implications of the Employee Retirement Income Security Act of 1974 (ERISA), which was enacted in the U.S. on 2 September 1974, are of vital importance to U.K. pensions' actuaries.Pension schemes which are established in the U.K. by U.K. branch operations of a U.S. parent are subject to the provisions of ERISA. Furthermore, there have recently been suggestions that U.K. subsidiary company operations of a U.S. parent might also be required to prepare ERISA-style reports.Since U.S. enterprises account for some 13% of the U.K.'s total gross product in manufacturing in the private sector, almost every U.K. insurance company, firm of consulting actuaries or pension consultants will have come into contact with some aspect of, or question relating to, ERISA.

AGI establishes Congressional Fellowship

The American Geological Institute (AGI), in cooperation with the American Association for the Advancement of Science (AAAS), invites postdoctoral scientists or engineers and professionals in the geological field to apply for the recently established AGI Congressional Science and Engineering Fellowship. AGI thus joins the AGU and approximately 20 other professional scientific and engineering societies who sponsor Congressional Science and Engineering Fellows. AAAS coordinates the entire program, arranges the orientation and yearlong seminar programs, and assists in the selection process.By working for 1 year, beginning September 1, 1980, as a special legislative assistant on the staff of a member of Congress or congressional committee, fellows have an opportunity to contribute to the public policymaking process within Congress. The program includes an orientation on congressional and executive branch operations and a year‐long seminar program on issues involving science and public policy.

An Evaluation of the Need for New Information Technology to Support Branch Operations

The study focuses on the improvements in planning effectiveness and information selection that may result from a change in information processing technology at the middle management level. The subjects selected for inclusion in this study are branch managers and insurance executives from eight of the largest property-liability insurers. Participants were asked to work with and evaluate the comparative benefits of two information sources, one representing current practice-and the other representing new information technology. The latter information system utilized a computer terminal and interactive data accessing and forecasting routines. A significant number of decision science techniques has been developed and operationalized over the past three decades. However, the frequency with which quantitative models or the output of such models have been utilized successfully by line managers in their decision-making activities has been low-especially in view of the potential contribution of the models [1, 7, 9, 12]. Therefore, an implementation gap between the tools and techniques developed and the incorporation of those tools and techniques into management decision-making processes has resulted. The seriousness of the problem has heightened with advances in computer technology which now have made available to the field manager a plethora of peripheral and remote on-line, real-time access devices. The field manager could now submit input via a terminal to quantitative models and receive the output of such models as part of an overall computer-based information system of the firm. Whether managers at various levels in an organization will utilize the expanding capabilities of the organization's information system in order to increase the profitability of their respective operations is a critical issue today. The concept of implementation, as used in this paper, refers to the installation and use of quantitative models and data bases as part of an overall computerized information and decision-support system. The output of the system can be in the form of representations of the operating environment, solutions to planning and/or control problems, or simply Robert J. Campbell is an Assistant Professor of Accountancy, Miami Univerity, Oxford, Ohio. He has published in Taxes-The Tax Magazine and Cost and Management.

Problems Involved in the Organization of Computations in a Uniform Rearrangeable Control Computer System

Consideration is given to organization of parallel computation in the control computer system where the task is broken down into parallel-sequential segments (branches) depending on informational and logical conditions of program execution, As many single-type system control resources may be given to a program as there are current program branches. Each program branch may get as many single-type computational resources as there are ready-for-execution various or single-type instructions in the branch at the time. Free resources may be given to another program. Therefore, in addition to the conventional control levels (control of programs and instructions), the system has two more levels for program branch control and operator control. The joint application of the concepts of rearrangeability and parallelism enables effective adaptation of system hard- and software to different requirements of involved real-time control.

Transportation type problems with quantity discounts

AbstractIt is known to be real that the per unit transportation cost from a specific supply source to a given demand sink is dependent on the quantity shipped, so that there exist finite intervals for quantities where price breaks are offered to customers. Thus, such a quantity discount results in a nonconvex, piecewise linear functional. In this paper, an algorithm is provided to solve this problem. This algorithm, with minor modifications, is shown to encompass the “incremental” quantity discount and the “fixed charge” transportation problems as well. It is based upon a branch‐and‐bound solution procedure. The branches lead to ordinary transportation problems, the results of which are obtained by utilizing the “cost operator” for one branch and “rim operator” for another branch. Suitable illustrations and extensions are also provided.

Branching Restrictions and Commercial-Bank Costs

The relationships between bank size, organization, and operating efficiency have been the subject of intensive research.' For example, in recent articles the operating efficiencies of unit and branch banks2 and holding company and non-holding company organizations3 have been examined. To date, however, these efforts have not been extended to analyze the role of geographic constraints on the relationship between size, organization, and efficiency.4 Thus, in attempting to delineate new boundaries for allowable branching operations or justify existing restrictions, state legislators could appeal to little evidence on the effects of such constraints on bank operating costs. Accordingly, this paper compares the operating costs of banks in a sample of states which permit statewide branching with the costs of banks in a sample of states which allow only limited branching. The next section outlines a standard commercial-bank cost function and presents OLS estimates of the parameters of the cost function for banks in statewide branching states (SWBS) and banks in non-statewide branching states (NSWBS).

Panama as a Regional Financial Center: A Preliminary Analysis of Development Contribution

A of any kind is a city in which are concentrated financial activities-banking, insurance, and ancillary types of financial businesswhich cater to a region outside the city itself, which may include other cities as well. An financial center, like London or New York, and in a lesser way Paris, Hamburg, and Zurich, caters to the financial requirements of a region extending beyond the boundaries of the nation within which the city is located to embrace the whole world or a substantial part of it. In the case of London and New York, at least, the center developed from being a national financial center through the demand for financial services to cater to the needs of its government, citizens, and enterprises as they engaged in economic activities throughout the outside world or a significant part of it. In other words, the major international financial center developed from a strong base as a national financial center in a large and powerful country with the natural market support of citizens of that country who automatically turned to its financial center for financial services they needed in other countries and the advantage of knowing intimately the nature of the customers involved. Regional financial on the other hand, such as Hong Kong, Singapore, and Panama, derive their role primarily from a combination of geographical proximity to the countries in which the customers operate and the safety and ease of operation of subsidiaries, branches, and agencies of foreign banks whose head offices lie in the international financial centers, rather than in generating customers in other parts of the region through their own national size and international power and the competence of their own national banks in international financial business. In other words, they are largely hosts to foreign financial institutions that find it convenient to locate offices there rather than magnets of financial

Some Aspects of Industrial Movement from Johannesburg 1960–1972

Abstract The impetus to manufacturing movement from Johannesburg in the period 1960-1972 is examined. Analysis is undertaken of the employment-sizt: characteristics and the industrial structure of migrant establishmems and the study’s findings compared to those of previous investigations. Typically, the migrant firm is one undergoing a phase of expansion, employs over one hundred workers, is in the metal products or machinery trades, and effects movement through a complete relocation rather than by establishing a branch operation.

Fitting Branch Locations, Performance Standards, and Marketing Strategies to Local Conditions

THERE are many situations in which headquarters management desires to make proper allowance for local conditions in selecting new locations, evaluating current performance, and providing marketing support to several geographically separate units. Such units may include, for example, different sales territories, retail stores, banking facilities, and service stations. They could belong to such categories as branch, voluntary chain, or franchise operations. This article describes how chain marketing managers can more effectively screen new branch locations, set realistic performance standards for different communities, and pinpoint remedial actions through regression models. Examples are given from the savings field.
