The constant Internet growth and improvements in distributed technology have prompted the emergence of large-scale heterogeneous systems. Service-Oriented computing enables the design and development of heterogeneous distributedsystems.through composition of individual services. However, majority of existing service composition systems.have centralized execution control and management servers. We propose a new model for building distributedsystems. which is based on coopetition principle. The coopetition-based distributed system consists of a set of services that cooperate and compete in order to achieve the overall goal. Thus, the control and management of execution workflow are decentralized and divided between distributed services. In this paper, we describe a set of synchronization, communication, and collaboration mechanisms that provide the support for development of coopetition-based distributedsystems. The coopetition mechanisms are implemented as platform-independent Web Services conforming to the WS-* standard set.

Challenge of graceful migration through upgrades and updates is a daunting task for process control systems. Issues confronted include aging hardware and software, as well as shortage of process experts with knowledge of vintage control systems. We offer techniques and solutions for graceful evolution to current generation control system. Our approach covers entire system including HMI, Controller, I/O and Field Interface Layers. We showcase stepwise implementation approach while addressing the concerns. We also provide cost-benefit analysis and pre-requisites for choosing specific evolution path.
