Implementing ISA S88 for a discrete process with the Bottom-Up approach
(Wydawnictwa AGH, 2008) Linden, Dirk van der
During the nineties, the SP88 committee developed the ANSI/ ISA-S88 standard to improve the maintainability, flexibility, documentation (and other enhancements) of batch control plants. This standard links sequence- and formula- management software (on a computer platform) with control equipment (on a PLC or controller platform) in a structured way. The S88 models are developed to be as universal as possible. The implementation of a discrete process is treated in this paper. The presented application proves that a discrete process can be automated based on the S88 models as well, but the approach can differ from batching. For re-engineering an existing plant, the Bottom-Up is a good approach in general for small applications. The application of this paper introduces basic models and terminology of S88, and guidelines how to implement them.

Projektowanie dedykowanych systemów komputerowo wspomaganego harmonogramowania procesów dyskretnych
(Wydawnictwa AGH, 2009) Bach, Irena; Wójcik, Robert; Bocewicz, Grzegorz; Banaszak, Zbigniew
The way an enterpise's production capacity is used decides about its competitiveness. In that context studies aimed at designing of decision support systems (DSS) dedicated to discrete processes scheduling are of primary importance. The metodology of such DSS designing is presented on a projecs planning descission support system example. The concept of a new generation of interactive, game-like organized visual interface is proposed.
