ABSTRACT Increasingly, projects are executed by networks of organizations. The networked form of organization has many important implications for project risk management. Information processing theories introduce mechanisms for processing information inside organizations as well as among organizations to reduce the uncertainty and equivocality inherently present in international projects. This study aims to examine the risk management practices involved at a project network level through an empirical analysis of one complex large project network executed in a challenging institutional environment. With regard to network level risk management, the paper identifies eight formal information processing m...

ABSTRACT This paper presents robust optimization models for a multi-product integrated problem of planning and scheduling (based on the work of Terrazas-Moreno & Grossmann (2011) [1]) under products prices uncertainty. With the objective of maximizing the total profit in planning time horizon, the planning section determines the amount of each product, each product distributed to each market, and the inventory level in each manufacturing site during each scheduling time period; the scheduling section determines the products sequence, start and end time of each product running in each production site during each schedul...

ABSTRACT A feasibility assay is conducted for electromyography measure in sternocleidomastoid and platysma, tenting to use it on Brain-Computer Interface (BCI) feedback. It is proposed a case of study for four healthy subjects with an average of 35 years old, two females and two males. Methodology proposed includes signal acquisition and processing with feature extraction of RMS, Mean and Variance. The data are acquired with the AD board ...

ABSTRACT A key issue regarding the reliability of scientific prediction is uncertainty, which also affects its possibility as scientific knowledge. Thus, uncertainty is directly related to the epistemological limits of prediction in science. Within this context, this paper considers the obstacles to scientific predictions that are related to uncertainty. The analysis is made according to the twofold character of the limits of science, which is characterized in terms of the “barriers” and the “confin...
