The Tinkan Company produces one-pound cans for the Canadian salmon industry. Each year the salmon spawn during a 24-hour period and must be canned immediately. Tinkan has the following agreement with the salmon industry. The company can deliver as many cans as it chooses. Then the salmon are caught. For each can by which Tinkan falls short of the salmon industrys needs, the company pays the industry a 2 penalty. Cans cost Tinkan 1 to produce and are sold by Tinkan for 2 per can. If any cans are left over, they are returned to Tinkan and the company reimburses the industry 2 for each extra can. These extra cans are put in storage for next year. Each year a can is held in storage, a carrying cost equal to 20% of the cans production cost is incurred. It is well known that the number of salmon harvested during a year is strongly related to the number of salmon harvested the previous year. In fact, using past data, Tinkan estimates that the harvest size in year t, Ht (measured in the number of cans required), is related to the harvest size in the previous year, Ht1, by the equation Ht = Ht1et where et is normally distributed with mean 1.02 and standard deviation 0.10. Tinkan plans to use the following production strategy. For some value of x, it produces enough cans at the beginning of year t to bring its inventory up to x+Ht, where Ht is the predicted harvest size in year t. Then it delivers these cans to the salmon industry. For example, if it uses x = 100,000, the predicted harvest size is 500,000 cans, and 80,000 cans are already in inventory, then Tinkan produces and delivers 520,000 cans. Given that the harvest size for the previous year was 550,000 cans, use simulation to help Tinkan develop a production strategy that maximizes its expected profit over the next 20 years. Assume that the company begins year 1 with an initial inventory of 300,000 cans.

The director collected $3000 amount as funds for the tournament on the condition that the amount will be spent on buying prices and trophies and for the two-day tournament and also arranging food for people participating in the tournament. The funds were collected as donations from the people. However, the manager of the club said that as the club is struggling in making profits, $1500 would be spent on the tournament, and the remaining $1500 will be considered as pure profits. This was not acceptable by the person who arranged the funds for the tournament after convincing people that the entire amount will only be used on the tournament. 1. Was it right in challenging my manager? Should I have handled this differently?

Emily works for a small software company and oversees software quality assurance. The company recently developed an inventory control system for a national clothing manufacturer. The system gathers sales information on an hourly basis from clothing retailers nationwide. This information is then used by all departments (including the accounting, shipping, and ordering departments) to control the functions of the clothing manufacturer. Emily suspects that the inventory functions of the system are not sufficiently tested, although they have passed all their contracted (legal) tests. However, she is pressured by her employers to sign off on the software. Whilst she is only required to perform tests which have been agreed to in the original contract, her considerable experience in software testing has led her to be concerned over the quality of the system. Her employers say that they will go out of business if they do not deliver the software on time. Emily knows that if any section of…
Solenn and Nico Bolzico, both graduate students, moved into an apartment near the university.

Jennifer has a small business mixing and selling essential oils. One product is a mixture of two oils, lavender and peppermint. She asked her assistant, Carmen, to check on two suppliers to determine the costs for her next batch. Carmen contacted the suppliers and got quotes from each for the order. She misplaced the number of ounces of each oil she needed to purchase. The information she has is: Supplier A: lavender: $5.80$5.80/ounce peppermint: $4.20$4.20/ounce Total cost: $128.40$128.40 Supplier B: lavender: $4.50$4.50/ounce peppermint: $5.00$5.00/ounce Total cost: $124$124 She decides to solve a system of equations to determine the number of ounces of lavender, LL and of peppermint, PP, she should order. What system of equations can Jennifer use to find LL and PP?
Hyewon Kim owns her own catering business. She continually monitors her other expense costs, including the cost of liability insurance for drivers of her catering vans. This year, Hyewon’s auto insurer advises her that insurance rates for her coverage will increase by 15 percent next year. The insurance company also states that if Hyewon will institute a preemployment drug-testing program for those employees who will drive her vans, there will be no insurance rate increase. Hyewon does not currently require potential employees to agree to be drug-tested prior to becoming employed in her business, but it is legal to do so in her state. What should Hyewon tell potential employees about her reason for implementing a preemployment drug-testing program? What should she do if a potential employee refuses to agree to the test?

When SS Electroplating Company started the electroplating operations in a residential location in Bengaluru, it received a notice from the pollution Control Board to install the effluent treatment plant within 15 days, failing which they would seal the plant. The Director of the company collected the information that it would cost about 10,00,000 to buy an effluent treatment plant, an area of about 600 sq.feet to install it over a period of 2-3 months, & running cost of about 40,000 per month for the purchase of material like costic soda & others. The effluent contained nickel, synide, cromium, cadminum & zinc, which were to be treated separately using different chemicals. After effluent liquid of about 800 litres per day was treated, the sludge was to be dried, packed, stored & dumped in a government notified place. The entire process would not only cost substantial amount, but also would need additional area of about 600-700 sq. feet The company gathered information…
Case: AGUSTINE SCHOOL PROM Many children of high-income families in Cabanatuan City and Nueva Ecija are sent by their parents to study in exclusive schools in Manila. Unmindful of the costs, the parents maintain the view that real education has a high price tag. The public elementary schools as well as the public high schools are perceived, rightly or wrongly, as not being able to deliver the quality of educational services needed. Even if this is so, enrolment in public schools has swelled to more than 60 students per class. The rule in public schools, except college, is to accommodate everybody. Currently, the opening of Montessori and private elementary schools in the area has provided some relief to parents who want quality education for their children. The older private schools are now competing with the new Montessori and private elementary schools which charge higher tuition fees. Miss Jana Agustin is a teacher at the same time marketing officer to promote the school. She…
