  • A drawback of existing scientific workflow systems is the lack of support to domain scientists in designing and executing their own scientific workflows. Many domain scientists avoid developing and using workflows because the basic objects of workflows are too low-level and high-level tools and mechanisms to aid in workflow construction and use are largely unavailable. In our research, we are prototyping higher-level abstractions and tools to better support scientists in their workflow activities. Specifically, we are developing generic actors that provide abstract interfaces to specific functionality, workflow templates that encapsulate workflow and data patterns that can be reused and adaptedmore » by scientists, and context-awareness mechanisms to gather contextual information from the workflow environment on behalf of the scientist. To evaluate these scientist-centered abstractions on real problems, we apply them to construct and execute scientific workflows in the specific domain area of groundwater modeling and analysis.« less
  • Workflow Management Systems facilitate the description, modeling, analysis, enactment, and coordination of structured work processes by groups of people. These systems assist and mediate communication, interaction, understanding, and synchronization among collaborating people and processes within organizations. In this document, we review some of the salient history of workflow. Workflow systems and techniques have existed for decades but, despite progress in many areas, intelligent, industrial strength workflow systems are not well established; the models themselves tend to be too restrictive and the systems often lack flexibility. We believe that there are dimensions of human flexibility that are typically ignored within workflowmore » systems design. This document presents the CDO process meta-model which is a new model intended to address some dimensions of human flexibility within process models. This three dimensional meta-model characterizes various process models, and various process instances according to their level of performance, detail, and operationality. We also introduce Chautauqua, a process coordination system under development within the Collaboration Technology Research Group at the University of Colorado. We explain how Chautauqua addresses these three dimensions of human collaboration. We end by briefly making some projections about the likely state of workflow during the medium term future (e.g. year 2000).« less
  • Complicated business or engineering processes sometimes consists of a sequence of smaller tasks to be acted upon by several individuals collaboratively. We show how to use World Wide Web (WWW) for this type of workflow/process management. A task is modeled as a state and there are several types of transitions among the states. The model allows maximum concurrency for the tasks and reduces the waiting time between the task execution. The design of a software to automatically generate a workflow management system is described in this paper. A prototype of the system to integrate business processes has been constructed. Wemore » shall discuss the implementation issues of the software system.« less
  • The design of complex systems requires efficient tools and strategies to shorten the time-to-market interval from specification to product. The advent of frameworks was intended to combine different tools from different vendors to interact under a homogeneous environment. However, frameworks have become very complex software-systems that need experts to configure and maintain them. They are mainly used to integrate company specific products in one environment. Our approach of a Lean Integration Platform uses a standardized tool integration defined in the CFI Tool Encapsulation Specification. Based on this specification a decentralized tool server executes tool-requests distributed over a heterogeneous local ormore » wide area network. Of course, tool integration is only one problem to overcome in order to support tool-driven design. A complete coverage of the design domain requires apt solutions for design data management including versioning and configuration management, process management and project management, to name only a few. To create a lean and scalable system the integration platform concentrates on supporting workflow-driven designs with an open interface to additional components as flow editors, user management add-ons or a sophisticated product data management facility. The behavior of the work-flow system is highly configurable.« less
  • Sandia is a national security laboratory operated for the U.S. department of Energy by the Sandia Corporation, a Lockheed Martin Company. Sandia designs all non-nuclear components for the nation's nuclear weapons, performs a wide variety of energy research and development projects, and works on assignments that respond to national security threats - both military and economic. They encourage and seek partnerships with appropriate U.S. industry and government groups to collaborate on emerging technologies that support their mission. Today, Sandia has two primary facilities, one in Albuquerque, New Mexico, and one in Livermore, California. They employ about 7,600 people and managemore » about $1.4 billion of work per year. In 1995, a decision was made to move from their in-house developed systems to commercial software. This decision was driven partly by Y2K compliance issues associated with the existing operating system and support environment. Peoplesoft was selected for human resources and Oracle for manufacturing and financial. They implemented Peoplesoft for human resources (HR) in 1997. They then implemented 7 Oracle modules in manufacturing in October 1998, including WIP, BOM, engineering, quality, inventory, MRP, cost management and limited HR/purchasing/receiving functionality required to support manufacturing. In March of 1999, they brought a portion of their Projects module up to allow for input of project/task information by their line customers and on October 1, 1999, they went live with the fill-blown financial package. They implemented projects, GL, receivables, payables, purchasing, assets and incorporated manufacturing modules and HR. This paper will discuss the analysis and implementation of the purchasing module.« less
