Abstract

Wide use of automatic process control systems and the usage of high-performance systems containing a number of computers (processors) give opportunities for creation of high-quality and fast production that increases competitiveness of an enterprise. Exact and fast calculations, control computation, and processing of the big data arrays – all of this requires the high level of productivity and, at the same time, minimum time of data handling and result receiving. In order to reach the best time, it is necessary not only to use computing resources optimally, but also to design and develop the software so that time gain will be maximal. For this purpose task (jobs or operations), scheduling techniques for the multi-machine/multiprocessor systems are applied. Some of basic task scheduling methods for the multi-machine process control systems are considered in this paper, their advantages and disadvantages come to light, and also some usage considerations, in case of the software for automatic process control systems developing, are made.

Highlights

Nowadays an enterprise cannot exist in the competitive environment and even function at all if processes and operations control of production are not carried out in an automatic mode by control systems [9]
It is not necessarily to use automatic process control system (APCS) in production everywhere; it is possible to carry out automation step by step, starting with the labor-consuming processes, and processes requiring high accuracy
Basic task scheduling algorithms, which can be used in case of design of automatic process control systems, are considered

Summary

Introduction

Nowadays an enterprise cannot exist in the competitive environment and even function at all if processes and operations control of production are not carried out in an automatic mode by control systems [9]. These algorithms are used to create such task schedule or operations execution which in case of execution on APCS gives minimum time of result receiving [16]. Basic task scheduling algorithms, which can be used in case of design of automatic process control systems, are considered.
