Patient bill of rights 2001

Breaking gridlock on managed care reform, a bipartisan coalition in Congress introduced the newest version of a patient bill of rights. Unlike last year's ill-fated Norwood-Dingell bill, the Bipartisan Patient Protection Act of 2001 has strong bipartisan support; concern remains, however, on the provisions that allow patients to sue their managed care plan. The debate now focuses on the type of liability reform that Congress and the White House can agree on. If they are able to agree, a patient bill of rights may soon become law.     

Coastal Adaptation Planning in Fairbourne,Wales: lessons for Climate Change Adaptation

ABSTRACT

Adaptation to climate change is emerging as a central objective and policy frame for coastal communities. This paper examines recent climate change adaptation efforts in the UK, centring on the case of Fairbourne, Wales. The village is facing the long-term prospect of flooding and inundation due to the impacts of sea level rise. The recent Shoreline Management Plan for the area has recommended realignment of the coast and eventual decommissioning of Fairbourne. The paper draws on a qualitative research methodology of interviews, policy review and observation to narrate the case and provide key insights and lessons for planners working in environmentally vulnerable coastal settings and managing climate adaptation processes.     

Evolutionary Resilience and Strategies for Climate Adaptation

The aim of this study is to develop a framework by drawing on three broad perspectives on resilience, engineering, ecological and evolutionary, and to use this framework to critically examine the approach adopted by the draft London climate change adaptation strategy. The central argument of the study is that the Strategy's emergency planning-centred approach to climate adaptation veers between a standard ecological understanding of resilience and the more rigid engineering model. Its emphasis is on identifying ‘exposure’ and ‘vulnerability’ to risk from climate events and on bouncing back from the consequences of such exposures to a normal state, rather than on the dynamic process of transformation to a more desirable trajectory. The study concludes that fostering resilience involves planning for not only recovery from shocks but also cultivating preparedness, and seeking potential transformative opportunities which emerge from change.

Production planning for remanufactured products

This paper presents a methodology for production planning within facilities involved in the remanufacture of products. Remanufacturing refers to the process of accepting inoperable units, salvaging good and repairable components from those units, and then re-assembling good units to be re-issued into service. These types of facilities are common, yet many suffer from the unpredictability of good and repairable component yields, as well as processing time variation. These problems combine to make it extremely difficult to predict whether overall production output will be sufficient to meet demand. Low yields of key components can lead to shortages which require the facility to purchase new components for legacy systems, often with long lead times, thus causing overall delays. The approach developed here is a probabilistic form of standard material requirements planning (MRP), which considers variable yield rates of good, bad, and repairable components that are harvested from incoming units, and probabilistic processing times and yields at each stage of the remanufacturing process. The approach provides estimates of the expected number of remanufactured units to be completed in each future period. In addition, we propose a procedure for generating a component purchase schedule to avoid shortages in periods with a low probability of meeting demand. The proposed methodology is applied to an antenna remanufacturing process at the Naval Surface Warfare Center (NSWC). In this case study the proposed methodology identifies a potential shortage of a key component and suggests a corrective action to avoid significant delay in the delivery of remanufactured units.     

Revenue management for remanufactured products

Revenue management for remanufactured products has not been addressed in literature so far. There could be more than one quality level of the recovered products, which would draw different prices in the secondary markets. In this paper, we develop a pricing model to maximize the expected revenue from the recovered products. Numerical examples are included for illustration.     

The role of risk preferences and flexibility for risk management: lessons from a custom manufacturing environment

In this paper, we study the management of financial risks of a custom manufacturer in the specialty chemicals industry arising from increased volatility of profits caused by market uncertainty and growing competitive pressure due to globalization. We argue that such risk management can be established either by creating and utilizing flexibility or by adjusting the risk preferences. Using a model-based approach, we operationalize flexibility and risk preferences to show their effects on the profit/risk and the decision making of a firm through a stylized example motivated by the specialty chemicals business.

Screening new products for potential winners

New product success is predictable. This paper highlights the findings of an extensive study into new product success and failure, and pinpoints what separates winners from losers. The key success factors are: product superiority—delivering unique benefits to customers, upfront homework—before development gets underway, sharp and early product definition, a strong market orientation with constant customer contact and input, and quality of execution of key activities in new product process. Sadly many firms and new product efforts are lacking on these success factors. This points to the need for a more disciplined approach to product development. One solution proposed is the implementation of a stage-gate or formal new product process—a blueprint for the process from idea to launch. A generic stage-gate is outlined in the article. The experiences of managers in firms which have implemented such processes are investigated, and the performance results are positive: improved teamwork, less recycle, higher success rates and shorter cycle times.     

Reducing delivery times for OKP products

The management of the manufacture of ‘one-of-a-kind’ products (OKP) is a neglected field in production management. The key to an improvement in productivity and profitability in this field appears to depend mainly on a reduction in the delivery times for products, which in turn requires a reduction in material throughput times, and in design and production planning lead times. This paper looks at some of the ways which can be used to reduce OKP delivery times.     

Strategies for marketing new computer products

Using the example of the computer industry, this paper explains how the marketing of new ‘high technology’ products can be improved by tailoring the extent and focus of prelaunch marketing planning to the nature and focus of the marketing strategy chosen for the new product.     

Adaptation of some vehicle fleet mix heuristics

Standard models used for the combined vehicle routing and vehicle fleet composition problem use the same value for the unit running cost across vehicles. In practice such a parameter depends on several factors and particularly on the capacity of the vehicle. The purpose of this paper is to show simple modifications of some well known methods to allow for variable running costs; and also to assess the effect of neglecting such variability. Interesting numerical results, measured in terms of changes in total cost or/and fleet configuration, are found at no extra computational effort.     

Integrated Education for Resilient Urban Adaptation: Wildfire Risk Reduction in Australia

Abstract

Urban and regional planning education seeks, often through highly applied teaching, to develop students’ abilities allowing them to work meaningfully on emergent urban and regional issues. However, it is relatively uncommon that education itself develops alongside government policy and research agendas. This paper documents the development of a new tertiary wildfire management qualification prepared in partnership with planning and building agencies after the devastating 2009 Victorian wildfires. It is argued that the process of developing educational outcomes in this case paralleled an interactive and ongoing agenda of research, policy development and education that represents adaptive-ness facilitating resilience as learning and institutional change.     

ICT-based solution approach for collaborative delivery of customised products

Growing interest on business collaboration motivates today’s industries, especially small and medium enterprises (SMEs) to establish and manage dynamic and non-hierarchical business networks to respond to market opportunities with added business benefits. This business environment requires concurrent work and real-time information sharing between key business partners in order to design and develop customised products. The use of traditional communication media such as e-mail, phone and fax is not satisfactory to get real-time information and is time-consuming and most often ineffective. In such environments, an Information and Communication Technology (ICT)/Web-based technology supports real-time information sharing among networked SMEs for the collaborative design and manufacturing of customised products. This study proposes an innovative ICT platform supporting SMEs collaboration, through Web and the Internet of Things technologies, which follows the Net-Challenge conceptual approach and methodological guidelines for SMEs to form and operate virtual organisations for the collaborative development and delivery of customised products. The ICT Platform was assessed in three different industry domains, namely the textile and apparel, the footwear and the machine tools, respectively. This ICT solution promotes collaboration, with substantial advantages for SMEs including the reduction of costs and delivery time and improvement of the innovation potential.     

The experience effect and pricing for agricultural products

It has been found that for a wide range of industrial products the unit prices and costs decrease by a constant percentage when production volume doubles—this is called the experience effect. This unit price behaviour is also observed for certain classes of basic agricultural products. As international market competition increases, price behaviour differences among countries may lead farmers, their organizations and governments to better understand what are the causes of the differences so that they can maintain and improve their competitive position internationally.     

Coordinating pricing and production decisions for multiple products

We consider a dynamic problem of joint pricing and production decisions for a profit-maximizing firm that produces multiple products. We model the problem as a mixed integer nonlinear program, incorporating capacity constraints, setup costs, and dynamic demand. We assume demand functions to be convex, continuous, differentiable, and strictly decreasing in price. We present a solution approach which is more general than previous approaches that require the assumption of a specific demand function. Using real-world data from a manufacturer, we study problem instances for different demand scenarios and capacities and solve for optimal prices and production plans. We present analytical results that provide managerial insights on how the optimal prices change for different production plans and capacities. We extend some of the earlier works that consider single product problems to the case of multiple products and time variant production capacities. We also benchmark performance of proposed algorithm with a commercial solver and show that it outperforms the solver both in terms of solution quality and computational times.     

The resource recovery level decision for end-of-life products

Resource recovery from end-of-life (EOL) products is becoming increasingly engaged in by companies as a response to customer, consumer, government and social pressures, the electronics industry cites competitor pressures as being the main driver of EOL product take-back and recovery. Recovery can occur at three levels; i.e. product, part and material. Each of these options has economic and environmental advantages and disadvantages depending on the product type and a host of other influencing factors. The work described in this paper supports the decision as to the most favourable route from a cost and value perspective, a software model that provides such support is also described.

Competitive markdown timing for perishable and substitutable products

We model as a duopoly two firms selling their fixed stocks of two substitutable items over a selling season. Each firm starts with an initial price, and has the option to decrease the price once. The problem for each firm is to determine when to mark its price down in to maximize its revenue. We show that the existence and characterization of a pure-strategy equilibrium depend on the magnitude of the increase in the revenue rate of a firm when its competitor runs out of stock. When the increase is smaller than the change in the revenue rate of the price leader when both firms are in stock for all of the three possible scenarios, neither firm has the incentive to force its rival to run out of stock and if a firm marks its price down after the season starts, its inventory runs out precisely at the end of the season. When the increase is larger than the change of the price leader׳s revenue rate in one particular scenario, waiting until its rival runs out of inventory may be an equilibrium strategy for the larger firm even though this may lead to leftover inventory for itself. In other cases, there may be no pure-strategy equilibrium in the game. In certain regions of the parameter space, a firm׳s revenue may be decreasing in its starting inventory which shows that a firm may be better off if it can credibly salvage a portion of its inventory prior to the game. While most of our analysis is for open-loop strategies, in the final part of the paper, we show that the open-loop equilibrium survives as an equilibrium when we consider closed-loop strategies for an important subset of the parameter space.     

The Affordability of Flood Risk Property-Level Adaptation Measures

The affordability of property-level adaptation measures against flooding is crucial due to the movement toward integrated flood risk management, which requires the individuals threatened by flooding to actively manage flooding. It is surprising to find that affordability is not often discussed, given the important roles that affordability and social justice play regarding flood risk management. This article provides a starting point for investigating the potential rate of unaffordability of flood risk property-level adaptation measures across Europe using two definitions of affordability, which are combined with two different affordability thresholds from within flood risk research. It uses concepts of investment and payment affordability, with affordability thresholds based on residual income and expenditure definitions of unaffordability. These concepts, in turn, are linked with social justice through fairness concerns, in that, all should have equal capability to act, of which affordability is one avenue. In doing so, it was found that, for a large proportion of Europe, property owners generally cannot afford to make one-time payment of the cost of protective measures. These can be made affordable with installment payment mechanisms or similar mechanisms that spread costs over time. Therefore, the movement toward greater obligations for flood-prone residents to actively adapt to flooding should be accompanied by socially accessible financing mechanisms.
