We present a novel optimisation approach for incentive contract design within a project setting. the structure of the remuneration is one of the key challenges faced by the project owner when (s)he decides to hire a contractor. The proposed technique builds on the recently proposed contract design methodology by Kerkhove and Vanhoucke (Omega, 2015). Specifically, a novel multi-objective scatter search heuristic is proposed and implemented using parallelisation. Both single- and multi-population implementations of this heuristic are compared to the original full-factorial approach as well as commercial optimisation software. The results of the computational experiments indicate that the single-population parallel scatter search procedure significantly outperforms the other solution strategies in terms of both speed and solution quality.
The purpose of this paper is to explain why product-centric manufacturers utilize advanced services not as vehicles of transformation, but of reinforcement, to strengthen their established business model logic based on selling products and basic product-related services.

This study investigates how interorganizational imitation influences management control decisions in a supply chain setting. Control design in interfirm exchanges is traditionally thought to be based on the principle of matching, where organizations install MCS that align with the transaction context. However, despite these theorized interrelationships, misaligned transactions commonly exist in practice. In this study, we propose a framework on the potential sources of such misalignment. We argue that control misalignment can be attributed to imitating behavior, by which organizations adopt MCS following the example of other organizations. Based on survey data collected from firms involved in a supply chain triad, we demonstrate that buyers control their upstream suppliers partially by imitating how their downstream customer controls them. Notably, buyers appear to imitate despite variations in transaction context, creating a basis for misalignment in line with our predictions.
Although researchers have extensively stressed the critical role of line managers in the effective implementation of HR practices, little is known about what exactly causes managers to enact these practices. In this paper, we draw from signaling theory, theory of planned behavior and social exchange theory to investigate both the antecedents and the outcomes of front-line management's enactment of performance management (PM) activities. Results from two Belgian samples of 731 front-line managers and 425 employees show that line management's beliefs regarding the usefulness of PM activities mediate the relationship between HR support and line management's implicit person theory, on the one hand, and PM enactment, on the other. This relationship is moderated by the manager' span of control. Furthermore, line management enactment shows to be positively related to employee engagement and job satisfaction.

We propose two classes of semi-parametric estimators for the tail index of a regular varying elliptical random vector. The first one is based on the distance between a tail probability contour and the observations outside this contour. We denote it as the class of separating estimators. The second one is based on the norm of an arbitrary order. We denote it as the class of angular estimators. We show the asymptotic properties and the finite sample performances of both classes. We also illustrate the separating estimators with an empirical application to 21 worldwide financial market indexes.
The timely completion of a project is one of its main factors for success. During the scheduling phase, a project buffer can be installed to protect the project deadline. During the execution phase, tolerance limits that generate warning signals when the project deadline is endangered should be constructed to monitor the buffer consumption. These tolerance limits will be constructed for the dynamic progress data provided by the Earned Value Management/Earned schedule methodology (EVM/ES). In this paper, we incorporate information on the availability of scarce resources into the construction of analytical tolerance limits for EVM/ES, in order to improve the efficiency and reliability of these tolerance limits. In order to review the performance of the limits, a computational experiment has been carried out in which they are compared to analytical tolerance limits that disregard the availability of resources. Results have shown that the performance of analytical tolerance limits can be significantly enhanced by incorporating the available resource information.

The business process management (BPM) discipline is starting to recognize the importance of context-awareness. In spite of this recognition, few studies investigate the effect of diverse contextual factors on BPM. To fill this gap, the study statistically analyzes the effect of organization size and sector, as specific contextual factors, on the adoption of BPM. The latter is measured by means of BPM capabilities for which data was collected from 2309 employees in 72 organizations. The study relies on the Contingency Theory by hypothesizing that, in practice, organizations adopt BPM by taking into account factors that fit an organization's context. Surprisingly, the results do not show a dependency between BPM adoption and organization size, suggesting that BPM adoption levels can equally be achieved by large or small organizations. In contrast, a dependency is found for organization sector (partly based on market velocity), suggesting different BPM adoption practices and/or speed in different sectors.
