This paper deals with a multi-period fixed charge production-distribution problem associated with backorder and inventories. The objective is to determine the size of the shipments from each supplier and backorder and inventories at each period, so that the total cost incurred during the entire period towards production, transportation, backorder and inventories is minimised. A 0-1 mixed intege...

Based on symbolic manipulation program Maple and using Riccati equation mapping method several explicit exact solutions including kink, soliton-like, periodic and rational solutions are obtained for (2+1)-dimensional variable coefficient Broer-Kaup system in quite a straightforward manner. The known solutions of Riccati equation are used to construct new solutions for variable coefficient Broer...

Kevin J. Boudreau HEC Paris Nicola Lacetera Case Western Reserve University Karim R. Lakhani Harvard Business School This paper presents econometric evidence of two independent effects of adding more competitors on innovation: 1) a competition effect whereby increasing rivalry shapes, and often decreases, incentives to expend effort and invest in innovation; and 2) a parallel search effect wher...

In an age of rapidly increasing network complexity and diversity, the idea of “bringing intelligence to the network” is becoming more of a necessity than “future work”. Since the early 1990’s, agent technology has often been proposed as a way of achieving this more effective, robust and above all autonomous network control. This article provides a brief tour of current trends in network develop...

OBJECTIVES This study's purpose was to identify the elements of a definition of evidence-based patient-centered care (EBPCC), the barriers to using EBPCC, and strategies for overcoming these barriers. METHODS This research project used focus group methodology with participants drawn from Society of Teachers of Family Medicine (STFM) members who attend STFM meetings and are interested in the i...

This paper provides a proposal for a thesis on plan generation in multiagent planning domains with self-interested agents. The research area involves Coalition-Planning Games in which agents are trying to maximise their own utility but can enter into unbreakable deals with other agents. The goal of the research is to provide algorithms for agents to generate plans that form stable solutions.

Conventional wisdom tells us that poverty is an absolute measurable state of being, a lack of access to goods and services, and as such can be assessed by metrics and indices. Mohammed Yunus, founder of The Grameen Bank turns conventional wisdom on its head. For Grameen, poverty is a conceptual rather than spiritual lack. Poverty is in what we perceive. Recognizing this is a prerequisite for th...
