Assignment -1Sub: POM Submission Date: 13/02/2013 SEM –II Example 1: Following Table shows various tasks in an assembling operation. Find a) Theoretical minimum cycle time b) Theoretical minimum number of workstation c) Assign task to workstations using the LOT rule d) Calculate the efficiency of the assembly line. Task A B C D E F G H I Example 2 Maureen Marcy is designing the layout for a new business in town, The collegiate Spa. From visiting spas in neighboring towns, she has compiled the following data on movement between spa activities. Help Maureen determine where to locate each activity on a 2*3 grid so that nonadjacent moves are minimized. 1 1- Relaxation Launge 2- Facial 3-Massage 4-Power Shower 5-Mineral Bath 6-Suana 10 30 50 2 50 3 25 4 5 75 6 75 50 25 50 Precedence Requirement C A A,C A B D G G,H Task Time (min) 10 20 30 15 10 20 10 15 15 50 D Performance Time (min) 1 2 2 4 3 4 . theoretical minimum no of workstations. Using the following information. compute cycle time.E C. Which layout is better? Layout A Layout B 5 3 4 1 2 6 4 5 3 2 6 1 Product M N O Dept Processing Sequence 6-4-3 1-5-2 4-2-6 Quantity per Month 1000 2000 3000 Example 4: The TLB Yogurt Company must be able to make 600 party cakes in a 40-hour week. No diagonal movement is possible. draw precedence diagram. The distance between adjacent dept is 10 m.Example 3: Figure given below shows two layout options for a facility. The table shows the dept processing sequence of various products and their quantities per month. Balance the assembly line & calculate its efficiency. Work Element A B C D E F Precedence Requirement A B A. . Following table gives Factor ratings and location ratings (1 to 10) for the three locations. Noida and Gorakhpur. Factors Factor Ratings 3 5 4 2 4 3 1 3 Kanpur 4 10 9 6 8 7 5 3 Location Ratings Noida 6 5 10 7 3 2 1 8 Gorakhpur 3 4 5 6 7 8 6 4 Close proximity to markets Close proximity to raw materials Transportation facilities Basic Amenities Acceptance by local people Availability of cheap land Low construction costs Easy availability of cheap labor Example 6: A state university is attempting to locate the best site for a new student center and athletic complex.Example 5: There are three location options for a new leather goods manufacturing company.: Kanpur. These coordinates of these housing and class room areas and daily student populations are as follows: Anderson Dorm Complex X = 1000 Y= 1250 W=7000 Ball Housing Complex X=1500 Y=2700 W=9000 Carter Classroom Complex X=2000 Y=700 W=11500 Derring Classroom complex X=2200 Y=2000 W=4300 Determine the best site for the new student center & athletic complex. The university administration would like to know what the best location is relative to the four main concentrations of student housing and classroom activity on campus. Suggest the best location for the new factory. The assembly line operates 7.Example 7: The following table gives information about the existing facilities of a beverage company. if the marketing dept. and calculate efficiency.
