An Improved Counterexample To The Rudimentary Primal Algorithm, Robert Haas, Kamlesh Mathur, Harvey M. Salkin

Research Reports from the Department of Operations

The rudimentary primal algorithm (RPA) is a simple and convenient algorithm to solve all-integer integer programs; its considerably more complex alternative is the "simplified primal algorithm" (SPA) of Young [3] and Glover [1]. The RPA has not been demonstrated to converge, however; Mathis [3] and Salkin [4] have in fact presented counterexamples for which it cycles indefinitely with period six. The counterexamples depend critically, though, on a rigid choice of the "optimal" pivot columns; Mathis' example converges if alternative columns are selected, and we observe here that Salkin's converges quickly too. The issue thus remained open whether the RPA might …

An Efficient Resource Directive Algorithm For Multicommodity Network Flow Problems, Chandrashekhar Madhukar Khot

Research Reports from the Department of Operations

Resource directive algorithms for multicommodity network flow problems are decomposition schemes that work by transforming the problem into one of finding the best possible allocation of capacities to the competing commodities. The transformed problem has a piecewise linear convex master program, with single commodity network flow subproblems, which can be solved fast. Resource directive algorithms presented in the literature have attempted to exploit the convexity of the objective. However, the best resource directive algorithm available, the subgradient algorithm, remains heuristic in nature. On the other hand, optimizing algorithms are usually computationally effective variants of the revised simplex algorithm; are roughly …

Design Of A Model Generator For Simulation Modeling In Slam [Tm 610], Henry C. Co, Shih-Ken Chen

Research Reports from the Department of Operations

[Published circa 1986-1988]. We present a menu-driven model generator for simulation of job shop-like systems such as the flexible manufacturing system (FMS). The model generator creates a "combined discrete-network" model which can be run directly on the IBM-PC version of SLAM II. The model traces the flow of materials in a closed network of resources. A data file for the discrete-event elements of the SLAM model enhances the flexibility of the model generator. The resulting model has the capability to incorporate various types of work stations (machining centers, loading and unloading stations, inspection stations, heat treatment and cleaning stations, temporary …

Coordination Of Multilevel Optimization And Benefit Allocation For Cooperating Producers With Emphasis On Agricultural Integration, Asher Tsafrir, Hovav Talpaz, Arnold Reisman

Research Reports from the Department of Operations

This paper develops a methodology for: The joint planning of activities by several cooperating but independent producers, where such cooperation can have synergistic results and an equitable distribution of the benefits resulting from the activities executed according to the above plan. The first objective is addressed using multilevel optimization techniques and the second using concepts from Rawls' theory of distributive justice, Aumann-Shapley prices and methodologies of Billera and Heath and of Mirman and Tauman which rendered the above operational. Although the paper focuses on agricultural cooperatives it points out potential applications in the health services and in the public sectors.

We present a fast algorithm for finding the routing sequence of the transporter in a bay type AS/R system. The methodology requires minimal computer hardware and CPU time. It is based on the analysis of the tree date structure abstracted from the problem. Some test cases are evaluated on a 100-aisle by 50-items-per-aisle AS/R system configuration.

Sequencing In Flexible Manufacturing Systems And Other Short Queue-Length Systems, Henry C. Co, T.J. Jaw, Shih-Ken Chen

Research Reports from the Department of Operations

There is a proliferation of applied probability models in the literature on flexible manufacturing systems. Many of these models make the LIFO, FIFO assumptions, but in actuality, there are a host of other sequencing rules that can be, and are applied. We investigate the impact of the sequencing rules in an effort to validate the robustness of these applied probability models.

Managerial Focal Points In Manufacturing Strategy, Arnoud De Meyer

Research Collection Lee Kong Chian School Of Business

Through analysis of specific decisions in the management of manufacturing in 163 companies, we have identified the key dimensions along which mort of the differences among manufacturing strategies can be explained. Previous research—mostly based on clinical observations—has focused on describing the typical decision categories in manufacturing strategy. Our large sample has allowed us to move beyond that and focus on the differences among manufacturing strategies. Data were collected by mailed questionnaires as a part of a large research project ‘Manufacturing Futures’. The responses to a list of 35 specific current action programmes in manufacturing were reduced through a principal component …

A Proactive, Systematic Approach To Finding Research Topics In The Management And Social Sciences, Arnold Reisman

Research Reports from the Department of Operations

This paper offers a step by step methodology by which most if not all researchable topics within a given field of knowledge can be systematically identified. The method is based on transforming a descriptive taxonomy into a prescriptive one. Two disparate literature surveys, one for Combining Probability Distributions in Rational Group Decision Making and the other for Perishable Inventory Theory are used to demonstrate the efficacy of the procedure.

Expansion Of Knowledge Via Consolidation Of Knowledge, Arnold Reisman

Research Reports from the Department of Operations

This paper addresses the need to consolidate knowledge while expanding it by creating taxonomies and/or generalized formulations. A number of ways to achieve that end are delineated and embedded in a suggested taxonomy of taxonomies. Selected works from both the "hard" and the management sciences are summarized to demonstrate the variety of knowledge consolidating role models and to test the effectiveness of the Taxonomy of Taxonomies.

Evaluation Of Word Processing Cost Effectiveness, Nicholas E. Tedesco

Company Resistance To Complex Fasb Statements: The Case Of Sfas 33, Kenneth Yale Rosenzweig

Accounting Faculty Publications

Over the past fifteen years, the Financial Accounting Standards Board (FASB) has issued numerous pronouncements designed to narrow the differences in accounting practice and thereby increase the usefulness of financial statements by making them more comparable among different enterprises. Though questions have often been raised over the years about the complex and prescriptive nature of these pronouncements, Statement of Financial Accounting Standards No. 33, “Financial Reporting and Changing Prices” (SFAS 33), has perhaps been the most controversial. The above statement required subject companies to generate and publish information that was radically different from that produced in accordance with conventional financial …

The Expected Cost Of Ruin And Insurance Premiums In Mutual Insurance, Charles S. Tapiero, Laurent L. Jacque

Research Reports from the Department of Operations

The purpose of this paper is to provide a quantitative definition and assessment of the expected cost of ruin in mutual insurance. In addition, some implications are drawn regarding the actuarially fair premium policyholders may be willing to pay for mutual insurance. A special case is treated, yielding analytical results that allow a comparative static analysis of the effects of ruin on premium payments and an assessment of the cost of ruin-free mutual insurance contracts.

A Prognostication Of Just-In-Time Efficacy In American Manufacturing, Mark L. Kahan

Theses

"Just-in-time" is a Japanese philosophy of business management which has as its ideal the complete elimination of waste in the process of adding value to a product. Some experts have contended that its basis is not cultural, but technical, and is thus applicable to American manufacturing concerns. After an initial exploration of economics and productivity concepts, and of U.S. logistics, inventory, and purchasing practices, the matter of Just-in-time will be addressed, both theoretically and in terms of Japanese business and labor relationships and culture. Then, based upon a case study consisting of observations made at a traditional American manufacturer, this …

Ranges For Negotiation In International Countertrade, Duu-Cheng Fuh

Research Reports from the Department of Operations

Countertrade is a modern version of barter trading. This thesis provides a texonomy for the various formats of countertrade in practice today. Each of the formats classified is also mathematically modeled. Under the thoery of comparative advantage this thesis derives quantity ranges within which negotiations can take place and both sides will profit. The thesis proves that product bundling increases negotiating latitute. The thesis also is concerned with deviations from comparative advantage. The situations of absolute comparative advantage and of comparative disadvantage are introduced to calculate quantity ranges using various types of product bundling. The extent of government subvention and/or …

Minimization Of Total Tardiness In Many-To-Many Pickup And Delivery Systems, Carolyn Kidder Cuff

Research Reports from the Department of Operations

In the problem considered, the objective is to minimize the total tardiness in a schedule which includes many pickup and many delivery locations. Due to the large number of items and fixed number of vehicles, a feasible schedule picking all items up after their known ready time and delivering them before their due times generally does not exist. Algorithms for single and multivehicle instances are developed. A branch and bound algorithm developed for the single vehicle finds an optimal solution. However, its use is limited to comparatively small problems. The alternative heuristic consists of 2 phases. First, the vehicle is …

Physician Manpower Planning For Developing Countries, Fidelis Madeke Ikem

Research Reports from the Department of Operations

Physician manpower requirements of most developing countries can often be met by either developing local training facilities, by sending indigenes to train abroad, by recruiting expatriate physicians, or some combination of the above. Foreign training and having expatriate physicians often involve expenditures of scarce foreign exchange in competition with other development projects. Planning the training of physicians to meet the healthcare manpower requirements of a developing nation is viewed in this research as being analogous to capacity planning in a multi-stage industrial production of a single product. Physicians are the single "product" to be "produced". The number of medical schools …

Impact Of Hospital Administration Training: A Study, C A K Yesudian

IIMB Management Review

Historically hospitals were considered as charitable institutions and run bya few committed persons who carried almost the total burden of providing services. But today hospitals have not only grown in size, but also these have highly qualified professional, paraprofessional and technical manpower handling highly sophisticated technology, to provide high quality health careto a maximum number of pesons in need of different kinds of health services. Therefore, hospitals today are very complex organisations to be managed effectively and efficiently. However, professional management is lacking in our hospitals which has severe repercussions on the patient care delivery of the hospitals. Management problems …
