I. (i) What are the objectives of facilities planning?
(ii) State the important questions that must be resolved in developing a material handling plan that wi0 support manufacturing and distribution.
(iii)State the issues that may have a long range impact on the strategic facilities plan.
2. (i) Explain your understanding of: (a) material flow planning hierarchy, (b) work simplification approach to material flow and (c) principle of minimizing the cost of material flow.
(ii) Explain the concept of activity relationship and space requirements used as a foundation for the facility plan.
(iii)What are the advantages and disadvantages of product (line production) layout?
3. (i) The assembly task elements and their assembly precedence requirements are Immo. An output of approximately 65 units per hour is required and the plan is to produce them all on one assembly line. Show a schematic of the number of stations What is the gem] possible efficiency? Use Ranked Positional Weigh Technique (preferably) or trial and error method in solving the assembly line problem.

(ii) What is the purpose of buffer design in flow lints? State the two buffering techniques that use decoupling for the purpose.
(iii) State the two major costs involved in providing a buffer.
4. (i) (a) The average operator of a certain company performs at 100% (avenge path) and the tinge of performance is from about 60% to 140%, and the distribution is assumed to be oormaL Determine the station speed of the company's assembly line assuming that it is set for the operator whose pace is 85% of average (Z value for 25% or 15% a 1.04 or, -1.04).
(b) Suppose the assembly line is decoupled and the line could be act for an avenge operator, what would be the gain in station speed?
(ii) Explain the characteristics of the following two programs in the context of computerized layout of multiple items: (a) CRAFT and (b) CORE LAP.
(iii)State the basic requirements of computerized layout programs for multiple items.
5. (i) Explain the concept of manufacturing cell
(ii) What are the benefits of integrating manufacturing cell with Just-in-Time (JIT). Total Quality Management (TQM) and Total Employee Involvement (TEI) concepts?
(iii) What is your understanding of: (a) logistics system and (b) flow patterns?
6. (i) State the steps that we followed in designing a material handling system.
(ii) What are the desirable attributes of shipping and receiving facilities plans?
(iii) State the characteristics of. (a) powered roller conveyors. (b) bridge cranes. and (c) Industrial robots.
7. (i) What are the advantages of centralizing tool and gauge cribs in a production plant? (h) State under what circumstances it would be desirable to decentralize tool and gauge cribs.
(iii) As an industrial engines you are asked to conduct a feasibility study to justify the consolidation of tool and gauge cribs and presiding a dispatching system in a manufacturing plant so that tools and gauges can be delivered directly to the production operators and manufacturing inspectors.
(a) Explain clearly the specific advantages of such a system.
(b) How would you conduct the study with particular reference to the collection of the relevant data and information to justify the project?
