Managing stochastic demand in an Inventory Routing Problem with transportation procurement

We study an Inventory Routing Problem in which the supplier has a limited production capacity and the stochastic demand of the retailers is satisfied with procurement of transportation services. The aim is to minimize the total expected cost over a planning horizon, given by the sum of the inventory cost at the supplier, the inventory cost at the retailers, the penalty cost for stock-out at the retailers and the transportation cost. First, we show that a policy based just on the average demand can have a total expected cost infinitely worse than the one obtained by taking into account the overall probability distribution of the demand in the decision process. Therefore, we introduce a stochastic dynamic programming formulation of the problem that allows us to find an optimal policy in small size instances. Finally, we design and implement a matheuristic approach, integrating a rollout algorithm and an optimal solution of mixed-integer linear programming models, which is able to solve realistic size problem instances. Computational results allow us to provide managerial insights concerning the management of stochastic demand.     

Fostering innovation through innovation friendly procurement practices: a case study of Danish local government procurement

Innovation has been at the forefront of procurement policy in Denmark in recent years. The policy incentives emphasize public procurement of innovation as a way to accelerate the development and application of environmental and health technologies, but also as a way to achieve a competitive advantage, growth and job creation. This paper uses a single case study to illustrate the procurement of a chemical-free cleaning system by the local government in Denmark. It describes the public procurement of innovation project in the response to an unsolicited bid from the supplier, and highlights the importance of innovation-friendly procurement practice for supporting innovation. The study identified indirect innovation effects of public procurement and number of conditions that have supported success of public procurement of innovation project such as close and early engagement with supplier; role of supplier acting as a technology champion; competence for applying functional specification; political support; sufficient resource allocation and institutional match between involved organizations. These findings lend support to the idea that public procurement of innovation may have occurred as a result of innovation-friendly procurement practice regardless of the lack of an explicit intention to promote innovation and challenge assumptions on which emerging policy initiatives are based on. These findings also suggest that the local government procurement may have a role to play in supporting innovation that goes beyond current definition of public procurement as a mission-oriented instrument to be exploited for resolving social challenges. These understandings could contribute to further policy development that may lead to a situation where public procurement of innovation is utilized to a greater extent than it is today in Denmark.

Coal demand,market forces,and U.S. coal mine closures

Economic transitions have the potential to displace workers and cause social unrest. Coal mine closures and the resulting employment losses in rural areas have become salient issues. Using data on coal mine and power plant operation, we model closure as a function of expected profits, which allows us to compare the effects on mine closure of specific demand and supply shocks to expected mine profits. Increasing costs of production have had a large impact on closures, but lower natural gas prices and lower electricity demand have played more recently important roles.     

Social service purchasing in China: Rationale,features, and risks

As part of a broader program of market reform, China's local governments are progressing an agenda of purchasing child welfare and other social services from the nongovernment sector, primarily to expand capacity and address vast unmet need. This paper draws on current research evidence to explore the approaches to purchasing emerging in China, examining the rationale for purchasing and models of supply, competition, and regulation. While some approaches are modeled on direct service contracting, direct purchasing of social service “posts” is also used, aimed at achieving goals of professionalization alongside service expansion. Overall, the review shows purchasing is helping to rapidly expand service scale and capacity; however, regulatory strategies for managing and mitigating risks to quality and access appear lacking. This highlights the need for further scholarship aimed at developing the robust risk management strategies which are required to support high quality, sustainable provision of purchased services.     

中国共产党党内集中教育经验研究

纵观百年发展历程,在革命、建设与改革开放的关键时期,中国共产党始终高度重视以党内集中教育方式加强党的思想建设,推进管党治党,提高党的建设科学化水平,积累了宝贵的经验。有效开展党内集中教育,必须始终坚持以理论武装为首要目标和任务,始终围绕正确的政治路线和政治方向,聚焦党内突出问题,坚持以人民为中心的价值导向,坚持“关键少数”教育与“绝大多数”教育相结合,构建党内集中教育长效机制,不断巩固党内集中教育实践成效。     

A Qualitative Study on Home Modification of Rural Caregivers for People with Dementia

Opinions about the responsibility for procuring sheltered housing in Norway have been studied among people 50 and older. Until recently, Norway offered standard public provision, where the state has been the central provider and organizer of care for the elderly. The results indicate great support for public responsibility for providing sheltered housing for the frail elderly, which is only marginally affected by background characteristics. However, older people's attitudes as to whether they would choose private housing provision are affected by income, age, and knowledge of the market, and many are uncertain. Women and low-income groups are overrepresented among those who are uncertain.
