Identifying an optimal positioning strategy for new products is a critical and difficult strategic decision. In this research, we develop a genetic algorithm based procedure called GA SEARCH that identifies optimal new product positions. In two simulation comparisons and an empirical study, we compare the results from GA SEARCH to those obtained from the best currently available algorithm (PROD...

For a child with multiple physical challenges, toileting has often been regarded as a nuisance, an interruption, an added burden. New thinking about health and disability, however, has recast toileting as a critical intervention and an opportunity to teach meaningful skills. These skills, happily, are within reach for nearly every child. Provided with the right environmental modifi cations and ...

Motivated by applications in retail, online advertising, and cultural markets, this paper studies the problem of finding an optimal assortment and positioning of products subject to a capacity constraint in a setting where consumers preferences can be modeled as a discrete choice under a multinomial logit model that captures the intrinsic product appeal, position biases, and social influence. F...

There is a great need for having reliable and accurate positioning technique for many wireless network technologies such as the Wireless Ad Hoc Networks, Wireless Sensor Networks, Vehicular Ad Hoc Networks, and Wireless Local Area Networks. In addition, the Mobile Computing which still in the development phase requires good localization system for the mobile nodes. The system must allow each no...

The availability of reliable underwater positioning systems to localize one or more vehicles simultaneously based on information received on-board a support ship or an autonomous surface vessel is key to the operation of some classes of AUVs. Furthermore, there is considerable interest in reducing the number of sensors involved in acoustic navigation/positioning systems to reduce the costs invo...

OBJECTIVE To develop recommendations for positioning the second-generation pacing esophageal stethoscope for transesophageal atrial pacing in patients positioned prone (P), right lateral decubitus (RLD), and left lateral decubitus (LLD). DESIGN Prospective; patients assigned consecutively. SETTING Tertiary and university hospitals. PARTICIPANTS Thirty (10 in each position group) adult pat...

In this paper we address the problem of locating a mobile response unit when demand is distributed according to a random variable on a line. Properties are proven which reduce the problem to locating a non-mobile facility, transforming the original optimization problem into an one-dimensional convex program. In the special case of a discrete demand (a simple probability measure), an algorithm w...

The first Dynamic Positioning (DP) systems emerged in the 1960’s from the need for deep water drilling by the offshore oil and gas industry, as conventional mooring systems, like a jack-up barge or an anchored rig, can only be used in shallow waters. GustoMSC has been developing DP drill ships since the early 1970’s and it is still one of their core businesses. DP systems automatically control ...
