3. List and explain in detail various techniques to sustain continuous improvement.
4. You have been employed as a quality assurance manager for a small metal fabrication firm (100 people). Your first assignment is to certify the suppliers and schedule a visit to each. Make a checklist with scoring criteria for your visit.
5. Efficiency has been defined as “doing things better” and effectiveness as “doing better things.” Describe how benchmarking can be used to improve both efficiency and effectiveness.
6. Explain five benefits that could be realized by implementing an ISO 9000 quality system.
7. Briefly describe the difference between sequential engineering and quality by design (or concurrent) engineering.
8. Do those who smoke cigarettes or drink alcohol assume the risk of getting lung or liver disease? Do those who jump on a trampoline assume the risk of falling off? Explain your answer.
9. The bearing department is planning their schedule for the following week. They need an understanding of last week’s performance. The schedule called for two 8-hour shifts per day for five days. Downtime charged to production averaged 76 minutes per day. Downtime charged to maintenance averaged 135 minutes per day. Calculate the actual running time and the percentage of available time.
10. What are the advantages and disadvantages of document management on the Internet?
Quantitative Techniques
1. a. “Statistics is the nerve center for Operations Research.” Discuss.
b. State any four areas for the application of OR techniques in Financial Management, how it improves the performance of the organization.
2. At the beginning of a month, a lady has Rs. 30,000 available in cash. She expects to receive certain revenues at the beginning of the months 1, 2, 3 and 4 and pay the bills after that, as detailed here:
3. What is degeneracy? How does the problem of degeneracy arise in a transportation problem? How can we deal with this problem?
4. Give the various sequencing models that are available for solving sequential problems. Give suitable examples.
5. A company has determined from its analysis of production and accounting data that, for a part number KC-438, the annual demand is equal to 10,000 units, the cost to purchase the item is Rs 36 per order, and the holding cost is Rs 2/unit/pear
a. What should the Economic Order Quantity be?
b. What is the optimum number of days supply per optimum order?
6. A TV repairman finds that the time spent on his jobs has an exponential distribution with a mean 30 minutes. If he repairs sets on the first-come-first-served basis and if the arrival of sets is with an average rate of 10 per 8-hour day, what is repairman’s expected idle time each day? Also obtain average number of units in the system.
7. What is critical path? State the necessary and sufficient conditions of critical path. Can a project have multiple critical paths?
8. Explain and illustrate the following principles of decision making:
a. Laplace b. Maximin c. Maximax d. Hurwicz e. Savage f. Expectation
9. A salesman makes all sales in three cities X, Y and Z only. It is known that he visits each city on a weekly basis and never visits the same city in successive weeks. If he visits city X in a given week, then he visits city Z in next week. However, if he visits city Y or Z, he is twice as likely to visit city X than the other city. Obtain the transition probability matrix. Also determine the proportionate visits by him to each of the cities in the long run.
10. “When it becomes difficult to use an optimization technique for solving a problem, one has to resort to simulation”. Discuss.
Quantitative Techniques
1. Distinguish between decision making under certainty and decision making under uncertainty. Mention certain methods for solving decision problems under uncertainty. Discuss how these methods can be applied to solve decision problems.
2. Distinguish between probability and non-probability sampling. Elucidate the reasons for the use of non-probability sampling in many situations in spite of its theoretical weaknesses.
3. What are models? Discuss the role of models in decision-making. How can you classify models on the basis of behavior characteristics?
4. What are matrices? How are determinants different from matrices? Discuss few applications of matrices in business.
