Abstract
Today, production planning and scheduling becomes very important part of production management because companies have to react to dynamic market conditions and rising customers requirements for shorter delivery times, lower prices and better quality and services. They can use a lot of sophisticated methods and approaches to make their planning processes more efficient and thus meet growing customers requirements. However, using these new approaches is not so easy in all types of production systems. This paper deals with production planning and scheduling in discrete batch production that is just an example of very complicated production system. This type of production process is susceptible to demand fluctuation and facility exceptions and this implies bottleneck shifting. Therefore it is quite difficult to implement methods such as Theory of Constraints (TOC) for production planning improvement in the standard way. One part of this paper is a case study wherecurrent production planning and scheduling in real factory is improved just through the use TOC principles.
Highlights
One of the key activities of production management is manufacturing planning and scheduling that can greatly influence production performance
Production system, which is analysed below in this paper as a case study, had very similar problem with production planning and scheduling. This factory with discrete batch production wrestled with constraints resources and their low utilization as well.its production planning and scheduling process has been improved by using Theory of Constraints (TOC) principles and bottleneck management which has helped the company to shorten production lead times and reduce stocks as you can see in the paragraphs
It was processed the short analysis of other research works in the field of Theory of Constraints based production planning and bottleneck management where authors describe some difficulties with production planning in discrete batch production
Summary
One of the key activities of production management is manufacturing planning and scheduling that can greatly influence production performance. Already Tomas Bata, who founded the world-famous shoe company on the beginning of 20th century, regarded production planning as one of the most important parts of business management (Trnka&Bejčková, 2010; Zelený, 2010). He was gradually followed by famous managers who started to deal with production planning problems more frequently as they perceived its importance. One of these persons was Eliahu M. It is absolutely necessary to recognize and properly characterize the type of production process and choose the most suitable method for production planning improvement (Ferenčíková, 2011)
