Deterministic Approximations To Co-Production Problems With Service Constraints And Random Yields, Gabriel R. Bitran, Thin Yin Leong
Deterministic Approximations To Co-Production Problems With Service Constraints And Random Yields, Gabriel R. Bitran, Thin Yin Leong
Research Collection School Of Computing and Information Systems
Production planning problems where multiple item categories are produced simultaneously are examined. The items have random yields and are used to satisfy the demands of many products. These products have specification requirements that overlap. An item originally targeted to satisfy the demand of one product may be used to satisfy the demand of other products when it conforms to their specifications. Customers' demand must be satisfied from inventory. The problem is formulated with service constraints and a near-optimal solution is provided to the problem with a fixed planning horizon. Simple heuristics are proposed for the problem solved with a rolling …

Growing competition in the investment banking industry has given rise to increasing demand for high functionality software applications that can be developed in a short period of time. Yet delivering such applications creates a bottleneck in software development activities. This dilemma can be addressed when firms shift to development methods that emphasize software reusability. This article examines the productivity implications of object and repository-based integrated computer-aided software engineering (ICASE) software development in the context of a major investment bank's information systems strategy. The strategy emphasizes software reusability. Our empirical results, based on data from 20 projects that delivered software for …
How To Arrive At Computer Integrated Manufacturing: A 3-Year Survey, Arnoud De Meyer
How To Arrive At Computer Integrated Manufacturing: A 3-Year Survey, Arnoud De Meyer
Research Collection Lee Kong Chian School Of Business
The large majority of modern production companies have at their disposal a multitude of computer systems. The immediate challenge for these companies consists of integrating these computer systems and databases. How will one arrive at this integration? On the basis of a questionnaire administered in 1985, 1986 and 1987 among a group of large European manufacturers, one comes to the conclusion that this integration is one of the immediate priorities for this group of companies. They do not intend to implement turnkey systems. but instead will integrate the different databases and computer systems gradually. One can see emerging islands of …
Parameter Non-Stationarity In A Model To Estimate The Business Value Of Information Technology, Robert J. Kauffman
Parameter Non-Stationarity In A Model To Estimate The Business Value Of Information Technology, Robert J. Kauffman
Research Collection School Of Computing and Information Systems
Developing robust and refined measures to quantify strategic impacts is a major challenge facing researchers who seek to improve methods for IT investment evaluation. This paper presents a means to test for parameter "non-stationarity" in a model which quantifies the strategic contribution of IT. An iterative "jackknife" procedure is used to diagnose if different local competitive and demographic conditions present in branch banking enhance or suppress leverage on deposit market share associated with membership in an ATM network. Preliminary results suggest this approach will be useful for managers who need to evaluate similar ITs which operate in different environments.
Designing A Budgeting System With Planned Confusion, John Joseph Williams
Designing A Budgeting System With Planned Confusion, John Joseph Williams
Research Collection School Of Accountancy
The article explores the potential virtues of dual budgeting processes coexisting within a single budgeting information system for organizations experiencing changing environments. The treatment of discretionary cost activity in the traditional budgeting process is discussed and a comparison of the effectiveness of the techniques of zero-based budgeting and traditional budgeting is presented. Using both approaches simultaneously is said to hold potential for combining the best of both methods, but the cost-effectiveness of such a dual budgeting process is noted as a limiting factor.
