Purpose – Information analysis tools enhance the possibilities of firm competition in terms of knowledge management. However, the generalization of decision support systems (DSS) is still far away from everyday use by managers and academicians. This paper aims to present a framework of analysis based on Bayesian networks (BN) whose accuracy is measured in order to assess scientific evidence. De...

Scenarios for a manned mission to Mars call for astronaut extravehicular teams to be accompanied by semiautonomous rovers. These rovers must be able to safely follow the astronauts over a variety of terrain with minimal assistance. We propose a color-based visual tracking system as a high-speed sensory approach for astronaut following. In previous work we characterized the accuracy of the syste...

We study a firm selling two products/services, which are differentiated solely in their prices and delivery times, to two different customer segments in a capacitated environment. From a demand perspective, when both products are available to all customers, they act as substitutes, affecting each other’s demand. Customized products for each segment, on the other hand, result in independent dema...

This paper investigates the strategic environmental decisions of a luxury car manufacturer. Through case study research, the investigation sheds light on why and how the company is adopting green technologies. Being pressured by different stakeholders to become greener, luxury car manufacturers carry significant opportunities for environmental improvement given the nature of their manufacturing...

A constraint specifies a relation or condition that must be maintained in a system. It is common for a single user graphic system to specify some constraints and provide methods to satisfy these constraints automatically. Constraints are even more useful in collaborative systems, which can confine and coordinate concurrent operations, but satisfying constraints in the presence of concurrency in...

Balancing business strategy and operations between electronic commerce and brick and mortar channels (‘clicks and mortar’) is an ongoing challenge for many businesses. A group of traditional ‘brick and mortar’ firms were examined in order to understand how they balance strategy and operations between electronic commerce and traditional (brick and mortar) business channels. Results of the study ...

In this paper we explore computing max-plus algebra operations and discrete event simulations on parallel hierarchal heterogeneous platforms. When performing such tasks on heterogeneous platforms parameters such as the total volume of communication and the top-level data partitioning strategy must be carefully taken into account. Choice of the partitioning strategy is shown to greatly affect th...
