EDM: Earned Duration Management,a new approach to schedule performance management and measurement

The concept of schedule monitoring and control as one of the most important functions of project and program management has not been fully exploited. One possible explanation could be the dominance of the Earned Value Management System (EVMS, also known as EVM). EVM was originally developed as a cost management and control tool which was extended to track the schedule as well. EVM and its derivatives (e.g. Earned Schedule) use cost as a proxy to measure schedule performance to control the duration of the project. While there is a correlation between schedule, cost, quality, and scope of a project, using cost to control duration has proven to be misleading. In contrast to Earned Value and Earned Schedule, the authors have developed the Earned Duration Management (EDM) in which they have decoupled schedule and cost performance measures and developed a number of indices to measure progress and performance of schedule and cost, as well as the efficacy and efficiency of the plan at any level of the project. These new indices are easy to understand, have wider applications, and can be used by contractors, clients and the scheduling offices to assess and measure schedule performance. The newly developed duration performance measures are all schedule-based and can be used for forecasting the finish date of the project.     

An extension of the EVM analysis for project monitoring: The Cost Control Index and the Schedule Control Index

In this paper we propose two new metrics that combine Earned Value Management (EVM) and Project Risk Management for project controlling and monitoring. We compare EVM cost and schedule variances with the deviation the project should have under the risk analysis expected conditions.These two indexes allow project managers to analyse whether the project over-runs are within expected variability or there are structural and systemic changes over the project life cycle. The new monitoring indexes we present are the Cost Control Index and the Schedule Control Index.     

Development of virtual and real-field construction management systems in innovative, intelligent field factory

In this study, we proposed a concept of virtual and real-field construction management systems (VR-Coms), which is integrated with virtual construction simulation, planning, scheduling, and performance management systems to evaluate productivity and safety in virtual simulated and real-field constructions. And, we built up a computational environment to develop the VR-Coms. The VR-Coms offer supporting modules for learning and discovering solutions with objective to manage construction at right speed with improved humanware and constructability.

Application of system dynamics for developing financially self-sustaining management policies for water and wastewater systems

Recently enacted regulations in Canada and elsewhere require water utilities to be financially self-sustaining over the long-term. This implies full cost recovery for providing water and wastewater services to users. This study proposes a new approach to help water utilities plan to meet the requirements of the new regulations. A causal loop diagram is developed for a financially self-sustaining water utility which frames water and wastewater network management as a complex system with multiple interconnections and feedback loops. The novel System Dynamics approach is used to develop a demonstration model for water and wastewater network management. This is the first known application of System Dynamics to water and wastewater network management. The network simulated is that of a typical Canadian water utility that has under invested in maintenance. Model results show that with no proactive rehabilitation strategy the utility will need to substantially increase its user fees to achieve financial sustainability. This increase is further exacerbated when price elasticity of water demand is considered. When the utility pursues proactive rehabilitation, financial sustainability is achieved with lower user fees. Having demonstrated the significance of feedback loops for financial management of water and wastewater networks, the paper makes the case for a more complete utility model that considers the complexity of the system by incorporating all feedback loops.     

Comparison of two monitoring systems for Cu and Mo in the Swedish environment

Bio-geochemical samples (BGS) are roots of certain aquatic plants and mosses suitable for monitoring elements dissolved in stream water. The moose, a wild ruminant living in most parts of Sweden, represents higher trophic level and another manifestation of bioavailability. By analyzing BGS (n approximately 33600) and moose liver (n approximately 2400), a systematic survey has been performed in the terrestrial environment of Sweden. Cu and Mo are essential elements for life, and their presence is especially important for the Cu-dependent processes in ruminants. The availability of Cu and Mo as monitored in BGS and moose was visualized in the form of maps and subjected to further statistical analysis. The medians, with lower and upper quartiles indicated as intervals, for the country as a whole were: moose liver, Cu = 34 (20-59), Mo = 0.82 (0.58-1.06) mg kg(-1) wet weight; BGS, Cu = 50 (35-77), Mo = 9.0 (5.3-18.0) mg kg(-1) dry weight. The ranges of medians for the 22 Swedish counties were: moose liver, Cu = (20-62), Mo = (0.54-1.18) mg kg(-1) wet weight; BGS, Cu = (28-115), Mo = (5-47) mg kg(-1) dry weight. The relationships between the counties and the connections between the monitoring variables were elucidated by principal component analysis (PCA). It was demonstrated that two monitoring systems could give divergent results. An unexpectedly strong negative correlation was found between the county medians for Cu in BGS and moose liver. A possible explanation, based on the interaction between Cu and Mo in moose, could not be verified.

Soft systems methodology and integrated flood management: a study of the Adayar watershed,Chennai, India

This paper applies Soft Systems Methodology (SSM) within the context of action research and Integrated Flood Management (IFM). A case study from the Adayar watershed, Chennai, is provided as an example of how SSM can be used to understand complex situations and as a problem‐solving strategy for flood management. Flat topography, uncontrolled urban development, population growth, sand bar formation at the river mouth and low tidal action render complexity to flood management in Chennai. For effective flood management, a participatory and integrated approach, which includes stakeholders in the decision‐making process and an enabling institutional set‐up, is essential. As part of an integrated approach, the relationship between various organizations and the public is identified. SSM is an approach for addressing fuzzy problematic situations involving human activity. In this paper, SSM techniques like ‘Rich Picture Diagrams’ and ‘CATWOE analysis’ and participatory action research tools like ‘pairwise ranking’ and ‘force field analysis’ were investigated. Two workshops were conducted to define and explore the problematic situation, the role of various actors involved in the problem, to develop the conceptual model, to rank decision‐making criteria, and to analyse the forces for and against to solve the problem. The flood management approach provided in this paper can be used by government agencies and policy makers to manage floods.     

Environmental,social and economic information management for the evaluation of sustainability in urban areas: A system of indicators for Thessaloniki,Greece

The use of indicators constitutes internationally an important tool for assessing the progress achieved towards sustainable development. Measuring the sustainability in urban areas – which are crucial engines of local socio-economic development, but at the same time present concentration points of environmental decay – is a major challenge for environmental managers and decision-makers. This paper aims at the development and utilisation of a system of indicators as a dynamic tool for the management of environmental, social and economic information in order to evaluate sustainability in urban areas. In this context, guidelines for the system’s development and use are proposed, together with a suggestion for its communication among local stakeholders. An application of this system is demonstrated through a case study using the Greater Thessaloniki Area, Greece, a domain with considerable socio-economic development, which is also encountering significant environmental pressures.
