Question

Waymouth Manufacturing operates a contract manufacturing plant located in Dublin, Ireland. The plant provides a variety of electronics products and components to consumer goods manufacturers around the world. Cycle time is a critical success factor for Waymouth, which has developed a number of measures of manufacturing speed. Waymouth has studied the matter and found that competitive contract manufacturers have manufacturing cycle times (MCE) of about 37%. When last calculated, Waymouth's MCE was 32% Key measures from the recent month's production, averaged over all the jobs during that period, are as follows: Average Time (hours) 24.e 0.5 4.5 Activity New product development Materials handling Order setup Machine maintenance Order scheduling Inspection of completed order Pack and move to storage or ship Manufacturing assembly Order taking and checking Receiving and stocking raw materials Inspection of raw materials at start of production Required: Determine the manufacturing cycle efficiency (MCE) for the recent month (Round your answer to 1 decimal place.) Manufacturing cycle efficiency (MCE)

Answer 1

  

Ans.	Manufacturing cycle efficiency = Total processing time / Total cycle time * 100
	18 / 37.50 * 100
	48.0%
	*Calculations for Total processing time:
	Manufacturing assemly hours are the total processing time.
	*Calculations for Total cycle time:
	Materials handling	0.5
	Order setup	4.5
	Mahine maintenance	1.5
	Order scheduling	4.0
	Inspection of completed order	3.5
	Pach and move to storage or ship	0.5
	Manufacturing assembly	18.0
	Receiving and stocking raw materials	4.5
	Inspection of raw materials at start of production	0.5
	Total Cycle Time	37.5
	*New product development and Order taking & checking are not included in the
	calculation of Total cycle time.
