We consider operational planning horizons required for managing shop floor resources. Our concept of horizons is different from those developed in the literature for aggregate production planning; the focus is on operational-level decisions. Our problem is of scheduling machine setup changes and we conduct the study on a system implemented at a manufacturing facility. This system schedules machine...
Among the most important decisions managers make is the determination of the most effective advertising strategies (and their associated tactics) and the determination of the market segments for which each strategy will be effective. Little research has explored the application of prospect theory based framing tactics (described in the text) to advertising. In this research we empirically test three...
An operational two-stage expert system is built with rule induction. The first stage examines the admission decision process for applicants to an MBA program, while the second stage focuses on the prognosis for degree completion for those actually admitted. It is this performance prediction capability that is submitted as the major contribution of the system. While given the opportunity to make use...
This paper examines the relationships between the intensity of IT investment and four performance impact measures relating to computerization. Data were collected via a questionnaire survey of the retail industry in Singapore. Results suggested that the intensity of IT investment has negligible relationships with information quality and improvement in work environment. Information quality is positively...
This paper presents an integrated knowledge-based system (KBS) that assists project managers in identifying potential risk factors and the corresponding project risks. The knowledge acquired from previous experience is captured by the proposed project risk identification model which incorporates the work breakdown structure (WBS). The knowledge is then translated into rules for the KBS. A prototype...
Information systems (IS), in recent times, have moved away from their traditional role as back office support to a new role in which they are recognized as key organizational resources. This new role, and the introduction of new technologies, have led to new ways for organizations to restructure and manage their IS function. These changes have considerably altered the IS executive's work environment,...
Taguchi proposed a loss function approach for tolerance setting that trades off two conflicting factors, i.e., cost to improve quality and loss. This approach has been used in recent quality control activities. Since quality affects the customer preference for a product, the latter should be considered in the determination of quality level through tolerance setting. In this note, loss as a function...
Despite the growing recognition of the importance of managing knowledge for improving the competitive performance of organizations, there have been little systematic research attention to the dynamics of knowledge accumulation and their implication for corporate performance. This research study develops a model to address this lacuna. The model is based on a theory that stresses innovation and intra-organizational...
This study extends an earlier benchmark study which examined the intellectual structure, major themes and reference disciplines of decision support systems (DSS) over the last two decades (1970-1990). Factor analysis of an author cocitation matrix over the period 1991 through 1995 extracted five major areas of DSS research (group DSS, model management, implementation, design and an unnamed factor)...
