Object-oriented applications are increasingly being deployed in distributed computing environments. Technologies, such as Java RMI, and architectures, such as CORBA, DCOM, and Enterprise Java Beans, are facilitating and enhancing this trend. The performance and eventual success of these applications is dependent on distribution decisions made by the application designer. This decision is a comp...

We propose a dynamic slicing algorithm to compute the slices of aspect-oriented programs. We use a dependence based intermediate program representation called Aspect System Dependence Graph (AOSG) to represent aspect-oriented programs. Then, we propose the dynamic slicing algorithm for AOPs, which is an extended version of EMDS algorithm for object-oriented programs. Our algorithm is based on m...

BACKGROUND Prolonged standing has been hypothesized as a vital contributor to discomfort and muscle fatigue in the workplace. The objective of this study was to develop a decision support system that could provide systematic analysis and solutions to minimize the discomfort and muscle fatigue associated with prolonged standing. METHODS The integration of object-oriented programming and a Mode...

Concurrent Design (CD) involves collaboration, coordination, and information-based co-decision making within a potentially distributed multifunctional team. This paper shows that a generic process-centered environment kernel, based on fine grain and decision-oriented task modeling, using customizable product models, providing capabilities for task model refinement at run time, and true collabor...

This paper introduces a novel approach to the real-time decision-making in service-oriented manufacturing systems, addressing the myopia problem usually presented in such systems. The proposed decision method considers the knowledge extracted from the Petri nets models used to describe the services process behavior, mainly the T-invariants, combined with a multi-criteria function customized acc...

in this study, mazandaran water and wastewater company’ performance is evaluated by using an input-oriented data envelopment analysis. as a principle, the performance of each organizational unit or organization should be measured as far as possible and what cannot be evaluated cannot be well governed. one method of evaluating the performance of units is data envelopment analysis method. one of ...

Diagnostic decisions in dynamic environments often require trade-offs between decision accuracy and timeliness. The longer a diagnostic decision is postponed, the more the accuracy of the decision may increase, while at the same time the probability of successfully executing remedial actions decreases. Kerstholt (1994) reports that in a task where a continuous process had to be monitored, subje...

Reusability is considered to be the key for achieving productivity and quality in software, and much has been claimed about the particular contributions of the object-oriented paradigm towards the achievement of these goals. Object-oriented frameworks are coarse-grained reuse units, composed of a set of classes speci cally designed to be re ned and used as a group. In this paper, we discuss the...

The modelling of pedestrian behaviour in a real-world environment is a complex problem, mainly due to the unpredictable nature of human decision making. Agent-oriented simulation moves away from traditional all-knowing and "controlling" simulations and towards reality, where pedestrians exhibit different behaviours depending on their knowledge of the environment and other personal characteristi...

Service-oriented architecture (SOA) have been adopted by organizations in a wide variety of industries, however, best practices have still yet to mature. This article, which is part of a larger study on SOA, develops a normative decision model introducing key factors that influence the timing and approach of adopting a SOA. The decision model is based on the results of multiple case studies of ...
