Application of Queueing Theory in Setting Standards of Auxiliary and Service Work

This article deals with possiblities of application of queueing theory for setting standards of auxiliary and service work. The aim of this article is a survey and description of situations where the queueing theory can be used as an effective tool for standardization of overhead work. It includes not only setting of optimal number of workers but also equipping workers with appropriate tools, setting of number of served machines or gadgets and frequency of their reparation. The opening part pays attention to some basic terms about queueing theory from the proffesional literature. It includes description of open and closed systems, their differences and their application in setting standards of auxiliary and service work Next chapter brings the advantages and disadvantages of these systems according to examples from the production. The next advantage of this theory is the fact that it can provide not only information about time consumption of the particular operation but also about its labour costs and other expenses. This is also very important source for the following decision of management. Open systems provide information about number of workers in the team of repairers and assemblers or how many workers should be employed in the dispatch office or in the stock. The closed systems can be used by the multimachines service, mainly by setting numbers of setters. According to independent research activity there is an example of application of queueing theory in setting optimal number of drivers of fork-lift trucks for particular working area of a company in the car industry.
