In our simulation project ProHTA (Prospective Health Technology Assessment), we want to estimate the outcome of new medical innovations. To this end, we employ agent-based simulations that require workflow definitions with associated data about workflow instances. For example, to optimize the clinical pathways of patients with stroke we need the time and associated costs of each step in the cli...

We live in a digital era. Nowadays almost all accounting and production project information are collected into long electronic spreadsheets that easily accessible for the managers so they can extract data analyze it according to their needs. In every work project, especially production, IT or manufacturing, there is need perform an elaborated risk management, just because gap of uncertainty fro...

Workflow management systems are widely adopted for implementing business processes. Archival workflow [3] is a precise representation of the archival process, reflecting the formal coordination mechanisms between archival activities and manual processes with respect to the specific requirements of the local governing body. Understanding key performance indicators of archival processes is consid...

Abstract Thermal injection methods are usually used for high viscosity oil. The results of previous studies showed that the combination SF and SFF had highest increase in oil recovery but still requires further study to determine optimum strategy. This work is purposed optimize development scenario a combined CSS-SF applied heavy field located Sumatera, Indonesia. factor NPV become objective fu...

Petroleum reservoir modelling requires effective multiscale methods for the numerical simulation of two-phase flow in porous media. This paper proposes the application of a novel meshfree particle method to the Buckley-Leverett model. The utilized meshfree advection scheme, called AMMoC, is essentially a method of characteristics, which combines an adaptive semi-Lagrangian method with local mes...

Since business workflows are closely related to enterprise performance, successfule execution of workflow is a critical driving force for strategic advantages of enterprise. Therefore, it is quite essential to customer satisfaction and productivity enhancement that structural errors in workflow instances must be detected and their performance must be evaluated before their enactments. For a str...

A workflow system defines, creates and manages the execution of business workflows with workflow engines, which interpret workflow definitions, and interact with task performers. As most of non-trivial organizations have massive amount of workflows to process simultaneously, there is ever-increasing demands for better performance and scalability of workflow systems. This paper proposes a workfl...

Grid computing is becoming a mainstream technology for large-scale distributed resource sharing and system integration. Workflow management is emerging as one of the most important grid services. In this work, a workflow management system for grid computing, called GridFlow, is presented, including a user portal and services of both global grid workflow management and local grid sub-workflow sc...
