This thesis addresses the problem of worst-case steady-state design of process systems under uncertainty, also known as robust design. Designing for the worst case is of great importance when considering systems for deployment in extreme and hostile environments, where operational failures cannot be risked due to extraordinarily high economic and/or environmental expense. For this unique scenar...

A1: After graduating from the Department of Mathematics at Hokkaido University (in Sapporo) in 1965, I engaged in developing an interpreter and a compiler for Lisp 1.5 at Hitachi Central Research Laboratory. The work was done based only on McCarthy’s manual [12]. When I was implementing the compiler, I realized that I was just looking at the interpreter written in the manual. Then the idea that...

Cyber-physical systems, used in domains such as avionics or medical devices, perform safety-critical functions where a fault might have catastrophic consequences (mission failure, severe injuries, etc.). Their development is guided by rigorous practice standards to avoid any error. However, as more software-based functions are integrated into a system, interaction complexity has increased signi...

Distributions of contact stresses at the neutral point in metal forming are very hard to be properly predicted due to the complex interface situation and lack of suitable friction models. In this paper, the dynamic friction model in which the friction depends on both time rate of strain and normal pressure has been applied to predict contact stresses in cylinder upsetting. Case studies have sho...

Clarity of Presentation • Does the introductory section explain motivation and orient the reader? • Are the concepts clearly present-ed? • Is the submission logically organ-ized? • Are titles and keywords used ap-propriately? • Is the submission's length appropriate to its scope? • Are conclusi...

Current research on business process management (BPM) outlines the importance of business process reengineering and its role in improving business process. As well, requirements on context-awareness go forward including BPM in many research areas. That is why, in this paper, we introduce a methodology for BPR consisting on: (i) using the process context in order to discover the process nature, ...

The growing use of commercial products in large systems makes evaluation and selection of appropriate products an increasingly essential activity. However, many organizations struggle in their attempts to select an appropriate product for use in systems. As part of a cooperative effort, the Software Engineering Institute (SEI) and the National Research Council Canada (NRC) have defined a tailor...

Process modeling has gained prominence in the information systems modeling area due to its focus on business processes and its usefulness in such business improvement methodologies as Total Quality Management, Business Process Reengineering. and Workflow Management. However, process modeling techniques are not without their criticisms [13]. This paper proposes and uses the Bunge-Wand-Weber (BWW...

Critical Infrastructure Protection importance is seen as basic element of maintaining vital societal functions from social and economic perspective. In relation to the needs of optimal and relevant protection and security measures selection is necessary to establish framework for Critical Infrastructure protection evaluation in relation and interconnection to risk assessment. This article discu...

Business process deviance refers to the phenomenon whereby a subset of the executions of a business process deviate, in a negative or positive way, with respect to its expected or desirable outcomes. Deviant executions of a business process include those that violate compliance rules, or executions that undershoot or exceed performance targets. Deviance mining is concerned with uncovering the r...
