A computer scientist's introductory guide to business process management (BPM)

Computers play an integral part in designing, modelling, optimising and managing business processes within and across companies. While Business Process Management (BPM), Workflow Management (WfM) and Business Process Reengineering (BPR) have been IT-related disciplines with a history of about three decades, there is still a lack of publications clarifying definitions and scope of basic BPM terminologies like business process, BPM versus WfM, workflow, BPR, etc. Such a myriad of similar-sounding terminologies can be overwhelming for computer scientists and computer science students who may wish to venture into this area of research. This guide aims to address this gap by providing a high level overview of the key concepts, rationale, features and the developments of BPM.

Courier problems

Courier problems

Courier problems comprise a set of recently proposed combinatorial optimization problems, which are inspired by some novel requirements in railway wagon scheduling. In these problems, scheduling strategies of some mobile couriers are considered. These mobile couriers initially reside at some fixed location. They are assigned some duties of commodity transfer between different pairs of locations. The scenario may be static or dynamic. The motivation is to optimize the movement of the couriers over the constraint of the traversed path or the associated cost. We discuss here some varieties of the courier problems formalized on graphs and address the potential methods of their solution.
