BBC is deciding whether to weld bicycle frames manually or to purchase a welding robot. If welded manually, investment costs for equipment are only $18000. The per-unit cost of manually welding a bicycle frame is $55 per frame. On the other hand, a robot capable of performing the same work costs $482000. Robot operating costs including support labor are $24 per frame. At what volume would BBC be indifferent to these alternative methods?
I need the excel formulas for the following, please! A concession stand manager at a baseball game must decide whether to have the souvenir vendors sell sun visors or umbrellas. There is a 30% chance of rain, a 15% chance of clouds, and a 55% chance of sunshine, according to weather predictions for the game. Because supplies can only be ordered 3 days before each game, the stand manager is unable to waituntil the day before the game to acquire the materials to be sold. The manager estimates the following profits will result from each decision, given the weather conditions. Given the following table, select the best decision using the following decision criteria.• Maximin• Maximax• Maximum likelihood criterion• Bayes’ decision rule Decision Rain Cloudy Sunny Sun Visors $-500 $-200 $1,500 Umbrellas $2,000 $0 $-900 Prior Probabilities 0.30 0.15 0.55
Glen Evans is an emergency medical technician for alocal rescue team and is routinely called on to renderemergency care to citizens facing crisis situations.

Glen claims his equipment has maximum probability offailure of 5%. Is he correct? b. What individual equipment reliabilities would guaran-tee an overall reliability of 96%?
Teddy Fields is the Kitchen Manager at the Tanron Corporation International Headquarters. The facility he helps manage serves 3000 employees per day. Teddy very much needs an additional dishwasher, and is interviewing Wayne, an excellent candidate with 5 years experience who is now washing dishes at the Roadway restaurant. Teddy normally starts his dishwashers at $12.00 per hour. Wayne states that he makes $13.00 per hour, a rate that is higher than all but one of Teddy’s current dishwashers. Wayne states that he would not leave his current job to take a “pay-cut”. Should Teddy offer to hire Wayne at a rate higher than most of his current employees? Why or why not?
Amazing restaurant uses customer checks with prenumbered sequence codes. Each person serving the food uses these checks to write up customer orders. Everyone involved is told not to destroy any customer checks; if a mistake is made, they are to void that check and write a new one. All void checks are to be turned in to the manager daily. Based on the above scenario, explain how does this policy help the restaurant control cash receipts?
A fundamental trade-off in the design of any business system is between efficiency and flexibility: one can't have ultimate efficiency and infinite flexibility at the same time. The simplification and standardization required to improve the efficiency of an operation inevitably restrict the things the system can do. In addition, the short-term changes and decisions needed to make an operation more flexible inevitably disrupt the smooth and predictable process flow needed for optimal efficiency. In the readings, you have seen that different system design philosophies and tools tend to generate different balances between efficiency and flexibility, which, in theory, allows you to design a system with the optimal balance between the two. As you have learned, the optimal balance between efficiency and flexibility depends on the competitive environment an organization expects to face in the future. You have also learned in this course that the future is notoriously hard to predict,…

Suppose the daytime processing load consists of 70% CPU activity and 30% disk activity. Your customers are complaining that the system is slow. After doing some research, you have learned that you can upgrade your disks to 2.5 times as fast as they are currently for $6,000 or you can replace your CPU with a 2 times faster one for $7,000. a. Which would you choose to yield the best performance improvement for the least amount of money? b. Which option would you choose if you don't care about the money, but want a faster system?
Quitmeyer Elec-tronics Incorporated manufactures the following six microcomputer peripheral devices: internal mo-dems, external modems, graphics circuit boards, CD drives, hard disk drives, and memory expansionboards. Each of these technical products requirestime, in minutes, on three types of electronic testingdevices, as shown in the table on this page.The first two test devices are available 120hours per week. The third (device 3) requires morepreventive maintenance and may be used only 100 hours each week. The market for all six computer components is vast, and Quitmeyer Electronics be-lieves that it can sell as many units of each product as it can manufacture. The table that follows summa-rizes the revenue and material cost for each product: DEVICE REVENUE PERUNIT SOLD ($) MATERIAL COSTPER UNIT ($)Internal modem 200 35External modem 120 25Graphics circuit board 180 40CD drive 130 45Hard disk drive 430 170Memory expansionboard 260 60 In addition, variable labor costs are $15…
