Which of the following is the correct value for the resulting line's efficiency? a. 0.500 b. 0.833 c. 0.973 d. 0.990 e. None of the above workstation cycle time? a. b. c. d. 4 minutes 5 minutes 6 minutes None of the above 13. Refer to the above information: What is the Theoretical Number of Workstations? a. b. 6 c. d. None of the above Which of the following is a basic type of production layout format? a. Process flow diagram b. Workcell Center c. Systematic plan d. Simo charts 16. Which of the following basic types of process structures is one which similar equipment or functions are grouped together? a. Project b. Workcenter c. Manufacturing cell d. Assembly line e. Continuous process 14. e. Manufacturing cel 17. Which of the following refers to the physical presence of the customer in a service system? a. Creation of the service b. Customer contact c. Intermittent production d. Continuous production e. None of the aboveExplanation / Answer
12.
Cycle time is maximum amount of time a product is allowed to spend at each workstation so that the production rate is achieved.
Cycle time = Available time/demand rate = TAKT time
Demand rate = 400 units per week
Available time = 8 hours per day x 5 days per week
(since the task times are given in minutes)
Available time = 60 minute per hour x 8 hours per day x 5 days per week = 2400 hours per week
Available time = 2400 hours per week
Cycle time = 2400 minutes per week/400 units per week = 6 minutes per unit
Cycle time = 6 minutes per unit
ANS: c. 6
13.
Theoretical Minimum number of workers required = Total work time/Cycle Time =
Total work content = 4 + 3 + 1 + 5 + 3 + 2 + 3 = 21 minutes
Theoretical Minimum number of workers required = ?Ti/CT = 21/6 = 3.5
Adjusted number of W/S = 4 work stations
ANS: c. 4
14.
ANS: a. project
Workcenter is combination of task to be done by single resource
Manufacturing cell – resources are arranged to produce particular product families
Assembly line – resources are arranged according to the requirement of product stages sequence.
Continuous process – resources are arranged according to the requirement of product stages sequence.
15.
Efficiency = Total work content/(# of workstation x cycle time) x 100
Efficiency = 25/(6 x 5) x 100
Efficiency = 88.33 %
ANS: b.
16.
Ans: e.
Except manufacturing cell, remaining options are used for representing process steps.
17.
Customer contact represent the physical presence of the customer in a service system.
ANS: b.
