Geographical Information Systems (GIS) involve the manipulation of large spatial data sets, and the performance of these systems is often determined by how these data sets are organized on secondary storage (disk). This paper describes a simulation study investigating the performance of two...

The network design problem with relays (NDPR) is defined on an undirected graph G = (V, E, K), where V = {1, … , n} is a vertex set, E = {(i, j) : i, j ∈ V, i j} is an edge set. The set K = {(o(k), d(k))} is a set of communication pairs (or commodities): o(k) ∈ V and d(k) ∈ V denote the...

Traditionally, IT security investment decisions are made in isolation. However, as firms that compete for customers in an industry are closely interlinked, a macro perspective is needed in analyzing the IT security spending decisions and this is a key contribution of the paper. We introduce the...

Scope and Purpose – For solving combinatorial optimization problems, neural networks have traditionally been outperformed by traditional heuristic techniques developed specifically for the problem in question. This research is a step toward integrating the problem specific knowledge embedded...

Reverse distribution, or the management of product return flows, induced by various forms of reuse of products and materials, has received growing attention throughout this decade. In this paper we discuss reverse distribution, and propose a mathematical programming model for a version of this...

The theory of incomplete contracts has been used to study the relationship between buyers and suppliers following the deployment of modern information technology to facilitate coordination between them. Previous research has sought to explain anecdotal evidence from some industries on the recent...

As Internet technologies for long-distance transmission fall in price, and the volume of data transmission surpasses that of voice transmission, networks developed solely for the Internet are becoming the trend. However, long-distance Internet technologies add considerable delay to the signal...

Purpose: This study aims to examine the factors influencing enterprise risk management and propose a framework for identifying and explaining the components of enterprise risk management. To enable broader analytical thinking about risk factors, the framework utilizes the resource-based theory...
