Today's Production Technology
1. Today’s Production in a Packaged World
By Gan Chun Chet (August 2016)
Quite remarkable that today production figures are governed by customers’ appetite. As
worldpopulationincreasesyearafteryear,thisdemandhastobe meetto serve the required figures.
In a period of economic recovery (also stability required) comes an era of rapid increase in demand,

This is a typical scenario of business atmosphere in today’s production environment which
affected investors.The risk involvedis too much in the sense where in some cases investorsare not
gettingbackthe promisedreturns.Onthe otherhand,itisa lossof investmentthat businessmanare
not able to get back its initial investmentvalue due tothe sluggishmarket inailingeconomy andthe
increased structural cost. Business closure and debt occurs amongst investors which dampen the
future.

Imagine the image and reputation of the particular organisation of interest at sight, are of
similar views on either side – whether you are a customer or a buyer. In fact, at point of sales, your
perception of your customer is the same as their perception on your products/services and there is
where a productispurchased.

not matter as long as the bottleneck in critical processes are identified and rectified, not affecting
those inthe waitinglist(orthroughput),i.e.toolongwaithoursordevelopmentleadtimeforinstance.
Itwasfoundthatthe bottleneckof the processmainly duetothe packagingmachineisineach
setup activity. Therefore, one of the new technology developed to meet this change requirement is
as follows:-

Is it A Changed World or Still A Changing World?
The drive for automation, whether fully or semi built-in has occurred. In the automated
productionenvironment,fullyautomatingrepetitivetasksandsemi-automateothers,will reduce the
cost of ownership eventually. However, it is unlikelyto eliminate all the manual task due to cost
matters. Therefore, perform in-house studies appropriately before embarking on the type of
