Managing Time in Workflow Systems
- …Even though currently available workflow management systems (WFMSs) offer sophisticated modeling tools for specifying and analyzing workflow processes, their time management support is rudimentary. Existing time management functionality mainly addresses process simulations (to identify process b…

Towards Distributed Workflow Process Management
- …Today, companies are driven by the rate at which technologies change and move towards global enterprises and virtual organizations in order to stay competitive. In global and virtual enterprises, business processes consist of multiple sub-processes that may span multiple time zones, organizational b…

The BeSS Object Storage Manager: Architecture Overview
- …this paper we have presented the architecture of the BeSS storage system. The alpha implementation of BeSS was completed in November 1993 and a beta release was completed in November 1994. BeSS has been implemented in C++ and it is operational for…

Transactions in the Client-Server EOS Object Store
- …This paper describes the client-server software architecture of the EOS storage manager and the concurrency control and recovery mechanisms it employs. Unlike most client-server storage systems that use the standard two-phase locking protocol, EOS o#ers a semi-optimistic locking scheme based on a mu…

Predictive Workflow Management
- …In this paper, we propose a new area for research in workflow management systems: the use of predictions in managing workflows. Predictions can be beneficial in making various decisions during workflow management such as: when to escalate? How much execution time to allow for each process step? What…

Reducing Escalation-Related Costs in WFMSs
- …Escalations refer to the actions taken when workflow activities, which constitute business processes, miss their deadlines. Typically, escalations increase the cost of business processes due to the execution of additional activities, the compensation of finished activities, or the intervention of hi…

Unix Network Peogramming
- …EOS is a generic object manager providing key kernel facilities for the fast development of high-performance database management systems and persistent languages. EOS is based on the client-server architecture with support for concurrency control and recovery. This document provides a brief overv…

Performance Evaluation of Two-Shadow Speculative Concurrency Control
- …Speculative Concurrency Control (SCC) [Best92a] is a new concurrency control approach especially suited for real-time database applications.…

Time Management in Workflow Systems
- …Management of workflow processes is more than just enactment of process activities according to business rules. Time management functionality should be provided to control the lifecycle of processes. Time management should address planning of workflow executions in time, provide various estimates ab…

Temporal Modeling of Workflows with Conditional Execution Paths
- …In this paper, we present a novel technique for modeling, checking, and enforcing temporal constraints in workflow processes containing conditionally executed activities. Existing workflow time modeling proposals either do not discriminate between time constraints that apply to disparate execution p…
