Modeling and Simulation of Workflow Processes Using Multi-level Petri Nets

Modeling and Simulation of Workflow Processes Using Multi-level Petri Nets

Modeling and simulation play an important role during the earliest stages of the developing life-cycle of workflow management systems. This work presented a modeling methodology for the specification of workflow processes. The use of n-LNS allows modular and hierarchical descriptions of the workflow management system. The models can be separately defined and then related through transition labeling; furthermore, the models may be easily updated because of the modularity and flexibility of the complete model. This feature allows addressing large systems exhibiting more complex behaviors than that obtained using “flat” PN.

Managing Workflow Processes through Access Control Policies

Managing Workflow Processes through Access Control Policies

An activity can be complex or atomic. A complex activity includes a set of activities as its children. An atomic activity has no child activities, i.e., for an atomic activity a, ¬x sup(x)=a. When a workflow model is instantiated as a process, an atomic activity should be assigned and it is also called a task. Each activity consists of a set of basic attributes denoted as a={aid, name, type, …}, in which aid, name and type are the unique id, name and type of the activity a. The function type of (a) returns the type of activity a. Inheritance relationships can be defined among activity types. An activity type can be referenced to some process models in the workflow library. For example, an activity type ―component development‖ in a software development project may have reference to two process models. One is ―internal development‖ as depicted in Figure 1(b) and the other could be ―outsourced development‖.

I. Overview. II. Vulnerability Management Improves Security. III. Automating Vulnerability Workflow is Crucial

While remediation is the ideal, cyber thefts of tens of millions of personal and corporate records at TJX Companies, DSW Inc., CardSystems Solutions, Inc. and many others show that some organizations need to work harder at proactive security. Effective remediation entails continuous processes that together are called Vulnerability Management. The workflow and related technology defined by vulnerability management help organizations to efficiently find and fix network security vulnerabilities and document compliance. This guide describes the major workflow processes of vulnerability management and how QualysGuard, as an on demand software-as-a-service (SaaS) automates most of these for fast, cost-effective remediation and compliance documentation.

Peer-to-peer form based web information systems

Peer-to-peer form based web information systems

The access rules we require in a form’s definition implicitly impose an order in which fields may be assigned values. Hence it is possible to infer a workflow process corresponding to a form. Turning to some more theoretical issues w.r.t. XForms, we note that the recommendation is very complex owing to the fact that users have a very ex- pressive language in which to describe forms. Not only does XForms use the full power of XML Schema’s type system, it also introduces a rich constraint lan- guage. This expressivity precludes finding decidable problems such as completion. In our ongoing work, we will take a different approach, limiting expressive- ness to allow the study of decidability problems. 2.2 Workflow Processes

Initiating Organizational Memories Using Ontology Network Analysis

Initiating Organizational Memories Using Ontology Network Analysis

Context-awareness: this has been recognized as the Achilles’ heel for OMs. One proposed remedy, advocated by proponents of marrying workflow processes and OMs (see, for example [3]), seems to work well in settings where workflow processes are ei- ther existing, or are relatively easy to identify and model. ONA takes a different approach in tackling context-awareness. We do not assume that workflow processes will exist, but we merely rely on ontological resources which we assume exist or could be constructed. Contextual relevance can be achieved in a number of ways thanks to the genericity of ONA. We could rely on ad- hoc technologies, such as profiling users’ interests by using agents [37] or by embedding personalization facilities in thin Web clients [24], or rely on identification of users’ tasks [11]. In addition, our reliance on organizational ontologies gives us the ability to exploit knowledge about users identity (obtained from system-entry logs), and thus help guess their information needs.

REANA: A System for Reusable Research Data Analyses

REANA: A System for Reusable Research Data Analyses

The REANA platform overview is presented in Figure 1. It consists of a client used by the researchers and a cluster that runs the platform itself. The users can interact with the system by means of a command-line client or a web user interface. Typical usage scenarios will be described in Section 3. The REANA cluster is composed of a set of micro-services that permit to instantiate, launch and monitor computational workflows based on client re- quests. The architecture of the platform will be described in Section 4. The computational workflows run on supported backends (Kubernetes on OpenStack) and use container tech- nologies (Docker) to instantiate necessary environments. A shared storage (Ceph) is used for the various workflow steps to exchange temporary results.

This indicates the management time required to develop a formal policy, document procedures, and audit results will yield a strong, positive return. We conclude that although security managers complain about the headaches involved in establishing repeatable processes and perform- ing regular audits, the data supports that this standard practice offers considerable value and fewer management headaches in the long run.

Service Oriented Architecture (SOA) in the Real World - Free Computer, Programming, Mathematics, Technical Books, Lecture Notes and Tutorials

Service Oriented Architecture (SOA) in the Real World - Free Computer, Programming, Mathematics, Technical Books, Lecture Notes and Tutorials

The acronym SOA prompts an obvious question – what, exactly, is a service? Simply put, a service is a program that can be interacted with via well-defined message exchanges. Services must be designed for both availability and stability. Services are built to last while service configurations and aggregations are built for change. Agility is often promoted as one of the biggest benefits of SOA – an organization with business processes implemented on a loosely- coupled infrastructure is much more open to change than an organization constrained underlying monolithic applications that require weeks to implement the smallest change. Loosely-coupled systems result in loosely-coupled business processes, since the business processes are no longer constrained by the limitations of the underlying infrastructure. Services and their associated interfaces must remain stable, enabling them to be re-configured or re-aggregated to meet the ever-changing needs of business. Services remain stable by relying upon standards- based interfaces and well-defined messages – in other words, SOAP and XML schemas for message definition. Services designed to perform simple, granular functions with limited knowledge of how messages are passed to or retrieved from it are much more likely to be reused within a larger SOA infrastructure. As stated earlier, recalling basic OO design principles regarding encapsulation and interface design will serve us well as we design and build reusable Web Services. We can extend these OO principles into the world of Web Services by further understanding the frequently cited ―four tenets‖ of Service Orientation:

3. Select tools and methods, and instruct team members. There are a variety of tools from simple to complex, manual to automated, those that follow “common sense” and those that follow a defined methodology. An important note is that many of the defined methodologies are derived from manufacturing processes. Assembly line production of widgets is often far removed from the focus on health care, and knowledge workers who perform mental processes. The best approach is one that marries the tools from

Service Based Support For Scientific Workflows

Service Based Support For Scientific Workflows

The following is a pilot implementation of a service based scientific workflow framework that provides effective access to diverse, distributed scientific tools across different organizations using the de facto Web Services technologies (UDDI, SOAP and WSDL). The idea is that every organization should publish their service descriptions with a centralized registry and have full control on how services interact and execute. The interested user will be able to locate these services and invoke them either on their own or as parts in a workflow. The framework will expose the workflow to the outside world as a means of enabling services from different organization to interoperate seamlessly where services communicate with each through standard interoperability protocols and perform the tasks defined in the workflows. The specific case study is composition and integration of Bioinformatics data acquisition and analysis services into an end-user workflow.

Achieving Dynamic Inter-organizational Workflow Management. by Integrating Business Processes, Events, and Rules*

Achieving Dynamic Inter-organizational Workflow Management. by Integrating Business Processes, Events, and Rules*

In the highly competitive and rapidly changing and expanding global marketplace, business organizations often form a virtual enterprise with others to achieve various business goals. Traditional workflow technology is used to coordinate the activities of an organization. Since the business environment of a virtual enterprise is highly dynamic, it is necessary to develop a workflow management technology that is capable of handling dynamic workflows across enterprise boundaries. This paper describes the development of a dynamic workflow model and a dynamic workflow management system for modeling and controlling the execution of inter-organizational business processes in a virtual enterprise environment. The dynamic inter-organizational workflows are used to integrate e-services provided by the participating organizations. The dynamic workflow model (DWM) described in this paper enables the specification of dynamic properties associated with a business process model. It is an extension of the underlying model of the Workflow Management Coalition’s Workflow Process Definition Language by adding connectors, events, triggers and rules as modeling constructs, encapsulating activity definitions, and supporting e-service requests. We also introduce a constraint-based, dynamic service binding mechanism for the enactment of business processes. The technique for run-time modifications of the process models to alter the course of executing workflow instances is also addressed in our work. The dynamic workflow management system is a part of an information infrastructure being developed for supporting Internet-based Scalable E-business Enterprise (ISEE).

Invoicing and Workflow

Invoicing and Workflow

To continue their improvement efforts, which they have been pursuing as part of an initiative for over five years, the focus is on automation and supplier enablement. They are currently receiving electronic invoices over a procurement network (for approximately 25% of the overall volume), and supplementing those efforts with document imaging of paper invoices and a portal for the remainder of suppliers. "We're offering a choice in terms of Purchase Order (PO) receipt and invoice channels, with hubs, EDI, portals, etc.," says the director. "The portal is the most difficult, though, due to log-on and manual data entry." Already boasting performance on-par with the Best-in-Class, their current efforts have netted the company year-over-year improvements in both processing time and cost (in the 5% to 10% range), on top of a slight increase in the percentage of early payment discounts captured. But they are not planning to rest on their laurels. Their plan is to replace the remainder of currently-manual processes with automation, by introducing data extraction from invoice images, implementing an electronic

Implementation of Systems Redesign: Approaches to Spread and Sustain Adoption

Implementation of Systems Redesign: Approaches to Spread and Sustain Adoption

Following identification of operational barriers, Lean tools and concepts—such as 5S, visual controls, and constraint management—are introduced to the project team through the use of health care-based case studies and hands-on simulation exercises. The latter exercises are developed specifically to mimic actual health care situations, such as locating equipment and supplies on a nursing unit and patient flow through an emergency department. Multiple rounds are conducted to simulate actual process improvement and to build team members’ confidence in applying Lean tools. These tools are then directly applied to the project team members systems and processes in order to improve the functionality of clinical processes associated with practice bundles.

E-Transcript Web Services System Supporting Dynamic Conversion Between XML and EDI

E-Transcript Web Services System Supporting Dynamic Conversion Between XML and EDI

As XML becomes a standard for communications between distributed heterogeneous machines, many schools plan to implement Web Services systems using the XML e-transcript (electronic transcript) standard. We propose a framework that supports both XML e-transcript Web Services and existing EDI e-transcript systems. The framework uses the workflow engine to exploit the benefits of workflow management mechanisms. The workflow engine manages the e-transcript business process by enacting and completing the tasks and sub-processes within the main business process. We implemented the proposed framework by using various open source projects including Java, Eclipse, and Apache Software Foundation’s Web Services projects. Compared with traditional EDI systems, our proposed system was evaluated to have higher reusability and scalability and save developers time and cost. It also provides users with rich look and feel user interfaces.
