While there have been many improvements in the teaching of operations
research/management science (OR/MS) in recent years, students continue to have great …

Object-oriented approaches have received attention in management information systems
development due to the advantages over the traditional approaches claimed by the …

The need to develop schedules for projects with resource constraints and cash flows arises

Formulation of a model involves organization of certain elements of reality into an abstract
structure that exhibits features and characteristics of the reality. The formulation process is …

From the formulation point of view, the Integer Programming (IP) formulation is no more than
indicating some decision variables in a Linear Programming model to integer variables …

Since formulating linear programming models from scratch is knowledge-intensive and,
hence, very costly, knowledge-based formulation support systems have been proposed. The …

This research investigates the automatic identification of typical embedded structures in the
Integer Programming (IP) models and automatic transformation of the problem to an …

The increase of computing power of the microcomputers has stimulated the building of direct
manipulation interfaces that allow graphical representation of Linear Programming (LP) …

Model management research investigates the formulation, analysis and interpretation of
models. This paper focuses on the formulation aspects of modeling so that the task can be …

In the integer programming model, structural identification and relaxation is an approach that
generates the Lagrangian problem of the model. The approach is based on a semantic view …
