This paper considers a multi-stage adaptive test (MST) where the testlets at each stage are determined prior to the administration. The assembly of a MST requires target information and target response functions for the MST design. The targets are chosen to create tests with accurate scoring and...

The innovative and dynamic nature of E-business enables small companies to compete with multinational corporations via online marketing. This paper serves as a guide from a practitioner’s perspective to embark in E-business while traditional marketing strategies are diminished. Three...

This article reports a series of process-based models for the development of e-business using enterprise software applications. Merging management technology in workflow systems is a critical step to provide service-oriented architecture and on-demand business. We propose a value-oriented...

This paper develops models for water planning that simultaneously consider investment and allocation decisions. The framework is demonstrated for a region which includes the counties of San Luis Obispo and Santa Barbara in California. The quadratic discontinuous mathematical programming...

This paper investigates the problem of obtaining a compromise/consensus from a set of ordinal rankings of n objects supplied by m committee members. Earlier work by Cook and Seiford (Cook, Wade D., Lawrence M. Seiford. 1978. Priority ranking and consensus formation. Management Sci. 24 (16)...

A specially-structured integer programming model, called the multiple-choice nested knapsack model, is developed in this paper. The model is characterized by variables which are partitioned into multiple-choice sets and resource constraints which are nested across the multiple-choice sets. The...

This paper presents the application of a modified mixed-integer programming algorithm to plan menus in which the portion size of the menu items can vary over a specified positive range. Previous mathematical programming formulations of menu planning problems have either required the variables...
