Optimal location of routes for vehicles transporting hazardous materials

Article Abstract:

The problem of optimizing the routes for transporting hazardous substances to minimize pollution and injuries to people is explored. Specifically, a fixed-route model which characterizes the problem such that meteorological conditions determine the emission of contaminants in the event of an accident is proposed. From this, a branch and bound procedure is developed to locate the optimal routes given that the origin and destination sites are fixed.

Optimal positioning of new product-concepts: some analytical implications and empirical results

Article Abstract:

A discussion of identifying specific locations for optimal new product-concept positioning in the perceptual product-attribute space centers on the efficient definition of discontinuous innovations. Results show that deriving accurate analytical expressions is intractable with at least three segments. Therefore, different approximations are used to identify the location of optimal new product-concept positioning.

A multicriteria Pareto-optimal path algorithm

Article Abstract:

A proposed efficient algorithm for deriving the complete set of efficient paths such as Pareto-optimal paths whihc are derived from a preassigned source node to a preassigned terminal node in a network. The complete set is obtained by collecting one efficient path per efficient objective vector since one of the latter may correspond to multiple and distinct efficient paths.
