BIM-integrated portfolio-based strategic asset data quality management

A building's strategic asset management (SAM) capability has traditionally been limited by its site-based management. With the emergence of needs from clients about delivering a long-term portfolio-based building asset management plan that minimizes the asset risk and optimizes the value of their asset portfolios, SAM Units have emerged as a...

Framework to Evaluate Power Portfolio Dispatch Considering Balancing Market Participation

The power grid is rapidly experiencing a transformation driven by renewable and climate targets which pose a huge challenge to maintain the system stability and reliability, thus balancing services become more crucial now than ever. To provide balancing services in a cost-efficient way, it is necessary to develop predictive models which can...

Enhancing value capture by managing risks of value slippage in and across projects

Project-based firms have to capture value from the projects in which they engage. This can be challenging as firms need to reconcile project goals and organizational goals while attempting to avoid the slippage of value to other actors. Drawing on interviews with architects and clients, this research reveals how architectural firms used the...

Evidence-Based Software Portfolio Management

Based on the large amounts spent by software companies to develop new and existing software systems, we argue that an evidence-based approach that focuses on a software portfolio as a whole should be in place to support decision-making. We developed EBSPM as an evidence-based, practical model to support software companies to actively steer at...

Effort and Cost in Software Engineering: A Comparison of Two Industrial Data Sets

Context: The research literature on software development projects usually assumes that effort is a good proxy for cost. Practice, however, suggests that there are circumstances in which costs and effort should be distinguished. Objectives: We determine similar-ities and differences between size, effort, cost, duration, and num-ber of defects of...

Improving energy performance of Dutch homes: coping with general investment behaviours

Purpose: Recent findings from a monitor containing around 1.5 million homes in the Dutch non-profit rental sector show that the improvement of the energy performance of the respective homes is mostly carried out in small steps: single measures per dwelling dominate and deep energy renovations are rare. From the way in which housing providers...

Stochastic Optimal Control Based on Monte Carlo Simulation and Least-Squares Regressiond

In the financial engineering field, many problems can be formulated as stochastic control problems. A unique feature of the stochastic control problem is that uncertain factors are involved in the evolution of the controlled system and thus the objective function in the stochastic control is typically formed by an expectation operator. There are...

Accurate and Robust Numerical Methods for the Dynamic Portfolio Management Problem

This paper enhances a well-known dynamic portfolio management algorithm, the BGSS algorithm, proposed by Brandt et al. (Review of Financial Studies, 18(3):831–873, 2005). We equip this algorithm with the components from a recently developed method, the Stochastic Grid Bundling Method (SGBM), for calculating conditional expectations. When solving...

Improving energy performance: many small interventions or selective deep renovations?

Recent findings from a monitor containing around 1.5 million homes in the Dutch non-profit rented sector show that the energy improvement pace in the sector in the last years is too slow to meet the nationally agreed level in 2020. The findings also show that the improvement of the energy performance of the respective homes is mostly carried out...

Exploring the Project Portfolio Manager's Role: Between a Data Manager and a Strategic Advisor

Many companies adopt project portfolio management processes to manage multi-project environments effectively and efficiently. One of the key roles in this process is assigned to the project portfolio manager. This role is formally defined in various guidelines and standards of portfolio management. However, it is yet insufficiently addressed in...

The Power Trading Agent Competition

This is the specification for the Power Trading Agent Competition for 2012 (Power TAC 2012). Power TAC is a competitive simulation that models a “liberalized” retail electrical energy market, where competing business entities or “brokers” offer energy services to customers through tariff contracts, and must then serve those customers by trading...

Toward a general model of portfolio decision making

We develop a general model of how new product development portfolio decisions are made based on four diverse case studies. Previous research has investigated portfolio decisions as individually discrete decisions. We find that portfolio decision-making has to be considered as an integrated system of domain-based processes that produce evidence-,...
