Question

HEAVYLOAD INC has 3 resources (Resource A, Resource B and Resource C) in its production process. The production process involves 3 products (Product A, Product B and Product C) being processed through these 3 resources. Currently, there is demand for 700 units of Product A, 1,200 units of Product B and 200 units of Product C per hour. The following bullets provide information about each resource:

At Resource A, the processing time for Product A is 14.112 seconds and for Product C is 50.4 seconds. Resource A does not process Product B. 4 workers currently work at Resource A but this resource only comprises 70% of their total work time for the company.

At Resource B, the processing time for Product B is 10.368 seconds and for Product C is 77.184 seconds. Resource B does not process Product A. 4 workers currently work at Resource A but this resource only comprises 80% of their total work time for the company.

At Resource C, the processing time for Product A is 17.28 seconds and for Product B is 10.368 seconds. Resource C does not process Product C. 4 workers currently work at Resource A but this resource only comprises 80% of their total work time for the company.

Assuming that demand for each of the 3 products (Product A, Product B and Product C) changes to 100 units per hour, answer the following questions:

a)What is the demand rate for Resource A, Resource B and Resource C in flow units per hour?

b)Find the capacity for Resource A, Resource B and Resource C in minutes per hour

c)Find the maximum hourly flow rate of Product A, Product B and Product C

d)Find the actual hourly flow rate of Product A, Product B and Product C

Answer 1

	Product A	Product B	Product C
Resource A Processing time	14.112 sec	-	50.4 sec	4 workers with 70% of total work time
Resource B processing time	-	10.368sec	77.184sec	4 workers with 80% of total work time
Resource C processing time	17.28sec	10.368sec	-	4 workers with 80% of total work time
Current demand per hour	700 units	1200 units	200 units
Assuming demand changes per hour	100 units	100 units	100 units
Processing time by Resource A for current demand in sec	9878.4	-	10080
(14.112* 700 units, 50.4 * 200 units)
Processing time by Resource B for current demand in sec	-	12441.6	15436.8
(10.368* 1200 units, 77.184* 200 units)
Processing time by Resource C for current demand in sec	12096	12441.6	-
( 17.28* 700 units, 10.368* 1200 units)
1 hour = 3600 sec
demand rate for Resource A per hour	2.744	-	2.8
(9878.4/3600,10080/3600)
demand rate for Resource B per hour	-	3.456	4.288
demand rate for Resource C per hour	3.36	3.456	-
Resource A in minutes per hour for 100 units	23.52	0	84
(14.112*100units/60sec for 1 min)
capacity of Resource A is 70%	16.464	0	58.8
Resource B in minutes per hour for 100 units	0	17.28	128.64
(10.368*100 units/60sec for 1 min)
capacity of Resource A is 80%	0	13.824	102.912
Resource C in minutes per hour for 100 units	28.8	17.28	0
(17.28*100 units/60sec for 1 min)
capacity of Resource A is 80%	23.04	13.824	0
