Impact of Information Technology Management Practices on Customer Service

Journal of Management Information Systems (2001)

Jahangir Karimi Toni M. Somers Yash P. Gupta

Recently,despite huge incentives and subsequent increases in investment in customer relationship management technology, many firms have not been able to increase their customer satisfaction index ratings. The purpose of this paper is to gauge whether IT management practices differ among firms where IT has a major role in transforming marketing, operations, or both, which give the firms advantage by affecting their customer service. Several research hypotheses are tested using data obtained from a survey of 213 IT-leaders in the financial services industry. The results clearly indicate that the IT-leader firms have a higher level of IT management sophistication and a higher role for their IT-leaders compared to IT-enabled customer focus, IT-enabled operations focus, and IT-laggard firms. This paper concludes with the implications for both researchers and practitioners.

Multi-Objective Optimization of an Ethylene Oxide Reactor

International Journal of Chemical Reactor Engineering (2011)

Allan Vandervoort Jules Thibault Yash P. Gupta

In this study, multi-objective optimization is performed for a reactor producing ethylene oxide from ethylene. The optimization considered three objectives: the maximization of the ethylene oxide production and selectivity, and the maximization of a safety factor related to the presence of oxygen in the reactor. The Pareto domain for this optimization problem was first approximated using the Objective-Based Gradient Algorithm, and the Pareto-optimal solutions were ranked using the Net-Flow procedure to determine the best operating conditions. From the optimization results, it is recommended that the ethylene oxide reactor be operated at high inlet pressure and gas temperature, and low inlet volumetric gas flowrate and chemical reaction moderator concentration. These operating conditions led to the highest ranked compromise solution, balancing the trade-off between each of the three objectives. Finally, it was found that a decrease in the inlet pressure or variation in the volumetric gas flowrate could readily lead to operating conditions outside of the Pareto domain, and these input variables should therefore be carefully controlled throughout operation of the reactor.

Impact of Competitive Strategy and Information Technology Maturity on Firms’ Strategic Response to Globalization

Journal of Management Information Systems (1996)

Jahangir Karimi Yash P. Gupta Toni M. Somers

:Recently the globalization of competition has caused many firms in the financial services industry to integrate their information systems. Based on a selective review of literature from strategic and information management disciplines, a model is developed to study the finns' strategic response to Europe 1992 and Canada-U.S. Free Trade Agreements. According to a survey of 213 managers, this study finds that competitive strategy, infonnation technology (IT) maturity and size influence: firms' perceived increase in IT investment. Further, this study fInds that the degree of IT integration within finns is a primary detenninant of finns' willingness to use IT as part of their strategic response to globalization. It suggests that the new competitive strategies will be increasingly technology-based global initiatives that are affected by the finns' IT maturity.

Design of a discrete robust controller using a first-order model approximation

International Journal of Systems Science (2005)

Jonathan R. Webber Yash P. Gupta

In this paper, a discrete controller with integral action is designed for a linear time invariant stable process based upon a first-order model approximation. Sufficient conditions in the form of simple inequalities are derived to ensure asymptotic stability. It is shown that this condition becomes both necessary and sufficient in the special case where the control interval approaches the open-loop settling time. The stability criterion is a closed-form inequality equation that is well suited for real-time calculation of the admissible controller parameter space.

Characteristic equations and robust stability of a simplified predictive control algorithm

The Canadian Journal of Chemical Engineering (1993)

Yash P. Gupta

Abstract In predictive control, control calculations are done such that the difference between the desired and the predicted response of the process is minimized. The number of points on the prediction horizon at which the error is minimized and the number of future control moves considered affect the on‐line computational effort involved in the solution of the constrained optimization problem. Earlier papers have shown that the control performance obtained using the DMC algorithm can also be obtained by using a simplified algorithm where the error is minimized at one point and one future control move is calculated. Because of its computational advantages, the simplified algorithm is analyzed further in this paper. Its transfer function is compared with the transfer function of the DMC algorithm. Characteristic equations to select tuning parameters are presented. The paper also compares the robust stability of the simplified and the DMC algorithms on SISO and MIMO process models. The results provide additional support to the viability of the simplified algorithm and thus indicate that it is possible for some processes to benefit from predictive control with only modest computational resources.
