A.
Interpretation: The possible contribution of ‘queuing theory’ for designing and/or controlling flexible manufacturing systems is to be discussed.
Concept Introduction:A flexible manufacturing system (FMS), as the name indicates, has a high degree of flexibility to quickly adapt to changing patterns of manufacturing so as to be able to produce a large variety of dis-similar items.Such systems, normally, consist of many computer controlled equipment which can be quickly reprogrammed for changes.
A queue is formed wherever there is a set of service providers and a set of service receivers−whether human or machine. Whatever are the rate of arrival of the service receivers and the servicing rate of the providers; sooner or later there will be either a queue of receivers or there will be unutilized providers. This concept has been researched mathematically to develop algorithms for various situations.

Interpretation:the possible contribution of ‘simulation’for designing and/or controlling flexible manufacturing systems are to be discussed.

Simulation means making an almost similar model (an attempted copy) of any product/process and to try it out several times to verify that the performance meets or shall met expectations. Computer applications enable large number of simulations in a very short time. This is mostly based on probability and statistical theories.

Programming is what prepares/schedules a computer for work. Mathematical programming involves use of optimizing models with high degree of mathematics. It provides a calculated analysis of the decisions likely to be taken by managers.

EBK PRODUCTION AND OPERATIONS ANALYSIS
- At Quick Car Wash, the wash process is advertised to take less than 6 minutes. Consequently, management has set a target average of 330 seconds for the wash process. Suppose the average range for a sample of 7 cars is 10 seconds. Use the accompanying table to establish control limits for sample means and ranges for the car wash process. Click the icon to view the table of factors for calculating three-sigma limits for the x-chart and R-chart. The UCLR equals seconds and the LCLR equals seconds.

And with a probability of 0.52 and a 0.48 probability of 65,000 at $550. we However, he uses his value analysis team (option b), the firm expects sales of 75,000 units at $770, with a probability of 0.78 and a 0.22 probability of 65,000 units at $770. Value engineering, at a cost of $100,000, is only used in option b. Which option for this has the highest expected monetary value (EMV)? The EMV for option a is $? The EMV for option b is $? Which has the highest expected monetary value. A or B?arrow_forwardPart 1 of 2 Jim's Outfitters, Inc., makes custom western shirts. The shirts could be flawed in various ways, including flaws in the weave or color of the fabric, loose buttons or decorations, wrong dimensions, and uneven stitches. Jim randomly examined 10 shirts, with the following results shown to the right. Shirt Defects 1 7 2 1 4 13 3 10 2 8 5 9 10 8 7 a. Assuming that 10 observations are adequate for these purposes, determine the three-sigma control limits for defects per shirt.

- Management at Webster Chemical Company is concerned as to whether caulking tubes are being properly capped. If a significant proportion of the tubes are not being sealed, Webster is placing its customers in a messy situation. Tubes are packaged in large boxes of 144. Several boxes are inspected, and the following numbers of leaking tubes are found: Sample Tubes Sample Tubes Sample Tubes 1 7 8 7 15 7 2 7 9 8 16 9 3 6 10 7 17 3 4 4 11 1 18 7 5 8 12 8 19 7 6 7 2 9 13 14 1 20 6 7 Total 121 Calculate p-chart three-sigma control limits to assess whether the capping process is in statistical control.
