We propose new heuristics along with an augmented-neural-network (AugNN) formulation for solving the makespan minimization task-scheduling problem for the non-identical machine environment. We explore four task and three machine-priority rules, resul

For the task-scheduling problem, we propose an augmented neural-network approach, which allows the integration of greedy as well as nongreedy heuristics (AugNN-GNG), to give improved solutions in a small number of iterations. The problem we address i

Given the orientation towards groups and the increase in the use of Group Decision Support Systems (GDSS) for distributed groups, we study communication mode and incentive structure to learn how these two factors influence group decision making. This

We propose a new approach, called Augmented Neural Networks (AugNN) for solving the task-scheduling problem. This approach is a hybrid of the heuristic and the neural networks approaches. While retaining all the advantages of the heuristic approach,

This paper presents and solves a hierarchical model for the location of service facilities and further looks at the operational issues associated with managing such facilities. By the very nature of the demand they serve, service systems require that

In today's virtual organizations, the type of communication mode that individuals use to interact with others may influence their decision outcomes and the information they exchange with others. The information that the individuals exchange is often

In this paper we study the problem of survivable network design (SND). The problem can be stated as follows: Given a set of nodes, possible edges and costs for each edge and the number of permitted node or edge failures between each pair of nodes, we

We study an integrated logistics model for locating production and distribution facilities in a multi-echelon environment. Designing such logistics systems requires two essential decisions, one strategic (e.g., where to locate plants and warehouses)

Combinatorial optimization problems are by nature very difficult to solve, and the Capacitated Minimum Spanning Tree problem is one such problem. Much work has been done in the management sciences to develop heuristic solution procedures that subopti
