Organizational learning: conceptual challenges from a project perspective

Do-it-yourself (DIY) is a staple element of the spare time activities of many households, but little is known about the extent to which basic repair work is carried out through DIY and about the quality of this work. Through secondary analyses of UK government data (English House Condition Survey and Family Expenditure Survey), this paper examines the scale of DIY work by owner-occupiers, how work is organized, the interrelationship of DIY work, the use of unpaid help, and the use of contractors. It considers the types of work carried out, the characteristics of those who tackle DIY or use unpaid help, the dwelling types most likely to experience DIY work, and the motivations of and constraints on those home-owners who do it. The paper concludes with a discussion on the policy implications of these findings for government and the building industry. Although most DIY work is cosmetic and does not deal with basic repair and maintenance, the sheer scale of DIY ensures that it makes a contribution to improving housing conditions. The provision of more advice, information and education by government, local authorities and the private sector could ensure that more DIY work is of better quality and that home owners give priority to essential repairs whether or not they tackle these themselves.

CBR Revision Model for Improving Cost Prediction Accuracy in Multifamily Housing Projects

For any construction project to succeed, it is very important to accurately estimate the construction cost during the project’s initial stage. This is why there has been much interest lately in cost prediction models that use case-based reasoning (CBR). It has been pointed out, however, that existing CBR-based cost prediction models may yield inaccurate results even though they could survey optimal similar cases, if the number of cases in the case base is not enough. As opposed to the existing CBR-based construction cost prediction models, this study developed a CBR revision model that reflects the “revise” phase of the CBR cycle (retrieve, reuse, revise, and retain) based on nine multifamily housing projects executed recently by “A” Housing Corporation. To verify the developed model, a case study was performed using three case projects completed by “B” and “C” Housing Corporations. The result showed that the prediction error ratio after the Revise (I) phase decreased from 97.44 to 22.58%. This model can be effective when there are insufficient established cases in the case base.     

从皇城到投资者的城市—北京城的扩展与建设

北京具有2000多年的城市历史，留下许多层面的城市结构和建筑类型，目前，北京城的心脏依然是故宫，而且老城的几何秩序似乎仍然主宰着整个大都市，作为13亿人民的政治和文化中心的北京，正寻找着能够充分体现现代化成就和中国特色的建筑风格，北京也同样必须作出巨大的努力，来解决实现了房屋，基本设施和环境问题，最后，北京需要一个区域性发展的新概念，来控制城市的动态扩张。     

有租借仓库并允许缺货的随机存贮模型

库存管理中已经存在的EOQ、(S,s)等经典模型,尚无法解决“有租借仓库”、“允许缺货”和“随机交货”并存的存贮管理问题。本文提出了针对上述三个条件并存情况下的存贮模型,将统计意义下单位时间损失费用作为指标函数来评价该方案,并将单品种固定库存总量随机存贮管理模型推广到多品种固定库存总量随机存贮管理模型中,给出了非线性规划模型。最后给出实例,采用优化算法在MATLAB下对模型求解。

Private Enterprise in Eclipse? A Reassessment of British Housing Policy in the 1940s

Conventional analyses of housing policy in most European countries treat the 1940s as a decade when private enterprise was eclipsed by social housing programmes. As a result, private enterprise is also eclipsed in most accounts of housing and housing policy in the early post-war period. This paper draws on the British experience to show that if the policy narrative is traced from wartime plans rather than from post-war action, and if the question of who actually built post-war social housing is raised, then a different picture emerges. From the middle of 1942 British civil servants and ministers were engaged in detailed planning for post-war housing, in both the short and long term. Private enterprise was assumed to have a major role to play in the long term, and a supporting role in the transitional period. In practice the post-war Labour Government relied on local authorities as housing developers, who themselves relied on private contractors to build the houses. The eclipse of private enterprise was, therefore, more apparent than real.
