Service channel queue system

The simulation, which ranks 5th among graduate queuing system students, doctoral students took as2 out (with Linear Programming). In the US in 1979 in a survey of 137 large companies, 84% of firms queueing system techniques reported that they used the simulation. In 1980 queueing system techniques AIIA (American Institute of Industrial Engineers)


Commissioned by the Operations Research queuing system department in a survey simulation recognition in terms of2 techniques, use and interest has been seen as in terms of 1. Technical. In 1989, large firms in the simulation from another survey use2 terms have been technical (Erol, 1998) are examples run also came to the door to see a variety of CNC machine operation.

One service channel queue system shown in Figure 1. Accordingly, the process of coming to the time between their arrival is a random variable (Taha, 1982). Likewise, the purpose of solving the problems of a random variable. Time to pass the necessary procedures for the transaction is to optimize the total cost of waiting for the mini (Hicks, 1994). Simulation input information necessary to solve the problems with the tail consists of the following: the time between the arrival of the transaction centers and processing times (Hillier queuing system and Lieberman, 1989).

This simulation study was carried out queuing system in the private sector in the joinery factory CNC machine tools. When giving an overview of the functioning of the production line; After the logs are cut and dried (35 x 45 mm) into sliced timber, sliced timber door frame is formed after combining the frame sections. This frame is mounted inside the honeycomb tissue with staples to be put in the door frame. The cut sheets stacked in the appropriate size, (91 x 2.11) plates on both sides of the frames are sent to the press and an adhesive surface is pressed. Then come the coatings pressing process, this process carried out after cutting and the edges of the door is brought to the dimension line is cleaned and net measure.

After this stage, the key sequence queuing system to these doors, hinges, latches, comes binoculars and surface scratches on the pattern of operations. These operations are conducted in high-speed computer-controlled CNC machine. The feeding of CNC cutting line and dimension line is, it was observed that the time randomly distributed the doors from coming here.


The queuing system door is subjected to the same process of change at all from the time of service. Changing shapes drawn on the door according to incoming orders and processing time as a result of this may be different for the doors. The purpose of the simulation is that the single-channel CNC accepting some assumptions we define as service providers is to observe the work at a certain time. One of the assumptions is to accept that the sizing and dimensioning of the line so that the door to a continuous mass production is made.
