经营策划与动态管理在海外冻结项目中的应用

由于冻结工法工艺的特殊性及新冠COVID-19后疫情时代影响,面临部分材料、设备在当地无法购买和加工,海上运输时间较长以及进出口清关手续复杂等难点,为了保证首个海外冻结项目高效施工和解决经营风险问题,同时有效精准掌握施工项目成本预算及目标控制,减少材料设备购买计划的重复性难题,首先提出了精细经营策划理念准确制定成本目标,其次通过海外市场了解确定了材料、设备国内外购买详细清单,最后通过实施过程中的动态管理把控实际成本与预算目标对比,为及时调整材料购买计划提供了依据。结果表明：第一次全面系统地取得了详细的施工材料设备详单;动态过程管理控制方法得到良好应用,取得节约16%成本效益;提高了海外项目团队管理水平。

The regulatory cycle stalled? An assessment of current institutional obstacles to regulatory reform in the provision of road-based public transport in Cape Town, South Africa

Wide-ranging and ambitious proposals for the comprehensive transformation of public transport systems in major South African cities, including Cape Town, have now been in play for a decade or more since the country’s post-apartheid transition. To date, progress in implementing such proposals has been, at best, much delayed and, in Cape Town, appears to have stalled, and may now be significantly compromised. This paper draws on aspects of the concept of regulatory cycles in the bus transport sector to explore some of the key factors which have given rise to this situation, focusing primarily on obstacles embedded in the present institutional framework which governs the provision of road-based public transport in the city. It specifically identifies difficulties in establishing an appropriately mandated and resourced agency at the local level to drive forward the transformation project and the sustained opposition of existing, largely ‘self-regulated’ minibus-taxi operators as key factors which have obstructed the introduction of the proposed regime of ‘regulated competition’. A tentative conclusion is offered to the effect that perhaps a partial or ‘hybrid’ transformation of the public transport system may be the best - and, indeed, possibly the most appropriate - outcome of the transformation process that can be anticipated under the present and foreseeable future circumstances prevailing in the city.

Sustainability Assessment of Transport Infrastructure Projects: A Review of Existing Tools and Methods

Abstract

Attempts to integrate sustainability in the decision-making process for transport infrastructure projects continue to gain momentum. A number of tools and methodological frameworks are available — such as rating systems, traditional decision-making techniques, checklists, and different evaluation frameworks and models. While these tools are highly valuable, some practical issues remain unsolved. There is also a need for more standardized tools to appraise the sustainability of transport projects. This paper is a presentation of a review on the current assessment tools of sustainability applied to transport infrastructure projects. The preliminary part of the paper is an explanatory and comparative analysis of the tools and methods in terms of their effectiveness to appraise sustainability. The analysis is a critical evaluation of the current state of the art to identify the limitations of existing approaches, point out new areas of research, and propose a sustainability appraisal agenda for the future.
