6 3] The MPS works within the constraints of Production plan but produces more specific schedule by individual products. 4] MPS and MRP are not related with each other. 18. In management prospective, Kanban is a visual indicator that triggers replenishment of item, such as 1] Card 2] Bin 3] Rack 4] Store SYMBIOSIS CENTRE FOR DISTANCE LEARNING (SCDL) Subject: Production and operations management Fill in the Blanks 19. BLANK means assignment of task or work to a facility. 1] Controlling 2] Loading 3] Coordinating 4] Directing 20. The loss due to non-absorption of overheads for the period the machine is under breakdown is called as :BLANK 1] Opportunity cost 2] Down time cost 3] Added setup cost 4] Cost of repairs 21.

7 1] Shutdown Maintenance 2] Design-out Maintenance 3] Corrective Maintenance 4] Preventive maintenance 22. The :BLANK includes preventive maintenance activities which are carried out when the machine is still running. 1] Running Maintenance 2] Design-out Maintenance 3] Working Maintenance 4] Preventive maintenance 23. BLANK is the amount of time the master schedule extends into future. 1] Time Fence 2] Supply Chain 3] Planning Horizon 4] Critical Path 24. In case of Batch Production , when batches are small, :BLANK is the ratio of direct workers to supervisors, and vice versa. 1] Equal 2] Higher 3] Lower 4] Negative 25. BLANK activity is concerned with looking at events that will occur in future. 1] Planning 2] Staffing 3] Scheduling 4] Coordinating SYMBIOSIS CENTRE FOR DISTANCE LEARNING (SCDL) Subject: Production and operations management 26.

The :BLANK ---- represents the irreducible minimum time required to complete an activity. 1] Pessimistic time 2] Standard time 3] Normal time 4] Crash time 28. BLANK cost is the resultant of failure of the product delivered to the customer or put into the service. 1] Prevention Cost 2] External Failure Cost. 3] Appraisal cost 4] Hidden cost State True or False 29. Production Planning can be centralised or decentralised, Production Control will always be diffusive activity. 30. Once three time estimates are converted into a single time estimate, there is no fundamental difference between PERT and CPM as regards to time analysis of the network. 31. A sampling plan which perfectly discriminates will have vertical OC curve.

9 32. Six sigma does not strive for perfection. 33. Any proposed change must not be intimated to workers in advance. 34. The role of operations management is to transform a company s inputs into the finished goods or services. 35. Six Sigma uses proactive thinking. 36. The main purpose of Kanban Systems is to streamline manufacturing and procurement processes rather than relying on computer simulation to suggest when to order. 37.
