Question
Chapter B, Problem 22P
a)
Summary Introduction
To determine: The optimal solution using linear programming software.
Introduction:
Linear programming:
It is a linear optimization technique followed to develop the best outcome for the linear programming problem. The outcome might be to maximize profit, minimize cost, or to determine the optimal product mix. The outcome will take the constraints present in achieving the solution into consideration.
b)
Summary Introduction
To identify: If there is any unused time on any of the machines at the optimal solution.
c)
Summary Introduction
To determine: The worth for adding an additional hour of time on third machine.
d)
Summary Introduction
To determine: The increase in profit by adding an additional 10 hours of time on the second machine.

PRODUCT MIX: The JP Manufacturing Company produces two products. Resource requirements for production are given in the table. There are 1500 hours of assembly worker hours available per week, 600 hours of paint time, and 200 hours of the inspection time. Regular customers will demand at least 150 units of the regular line and 90 of the super. Formulate an LP model that will determine the optimal product mix on a weekly basis.

A recruiter for a job placement agency is considering whether to pay $50,000 per year to lease a new recruiting facility in a prime location in Washington D. C. He estimates it will cost $50 per recruit to process the paperwork at this new location. He receives a $75 commission for each new recruit he processes. Part A - If the office space at this new location has design and effective capacities of 10,000 and 8,000 recruits processed annually, respectively, and 6,000 recruits will be processed per year, what will be the utilization of the office space?Part B - If his office space at this new location has design and effective capacities of 10,000 and 8,000 recruits processed annually, respectively, and he plans to be 90% efficient in his use of this space, how many recruits does he plan to process per year?
Benny is the manager of an office-support business that supplies copying, binding, and other
services for local companies. He must replace a worn-out copy machine that is used for black-
and-white copying. He is considering two machines, and each of these has a monthly lease
cost plus a cost for each page that is copied.
Machine 1 has a monthly lease cost of $639, and there is a cost of $0.030 per page copied.
Machine 2 has a monthly lease cost of $747, and there is a cost of $0.045 per page copied.
Customers are charged $.08 per page copied.
a. What is the break-even point for each machine?
b. If Benny expects to make 75,000 copies per month, what would be the monthly cost for
each machine?

- 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.arrow_forwardBenny is the manager of an office-support business that supplies copying, binding, and other services for local companies.
