|Abstract: ||The purpose of this paper is to present a study of mathematical model of system analysis of efficient production processes. Its
objective is to perform productivity balance calculation based on data obtained from injection moulding process. Discussion on
system analysis of production processes for productivity enhancement is presented. The definitions of machining time and idle
time are given. The importance of coefficient of machine is also discussed. The methodology adopted in the study was to
calculate the coefficient of machine of injection moulding process. The productivity balance diagram is presented to illustrate
various losses associated with productivity. The productivity balance is developed based on mathematical calculation proposed
and various productivity losses were identified. The improvement can be made based on these losses. An investigation was based
on data obtained from injection molding machine from a company in Klang Valley. The main findings from this study include
the main losses in injection moulding process can be divided among all the losses at the ratios of idle times as
0.45:11.11:0.1:0.06. These losses are QI = 0.003 parts/min, QII = 0.0562 parts/min, QIII = 0.0005 parts/min and QIV =
0.0003 parts/min. It is concluded that engineers have to create new machines with continuous processing without cyclic idle
time in order to step up the automation, to solve problem in changing automatic tool, to increase the reliability of the machine,
to create real automatic control of manufacturing system, to adapt automatic control of quality of parts and to determine
accurate and flexible production system.|
