A company with a capacity of 3,000 units a month has fixed costs of P1,500 a month and labor costs of P10 a unit. Material costs are P5 per unit. The company has been producing at 80 percent of capacity and selling its product for P20. What would its net income be at 100 percent at capacity. What would its net income be at 120 percent of capacity if it is assumed that 20 percent more products could be produced on overtime at an extra P3 labor cost per unit for all production above 100 percent?
During an eight-hour shift, 750 non-defective parts are desired as a result of a manufacturing operation. The default operation time is 15 minutes. As the operators of machine are inexperienced, the actual time they take to perform the operation is 20 minutes, and, on average, a fifth of the parts that start to be manufactured are lost. Assuming that each one of the machines used in this operation will not be available for one hour in each shift, determine the number of machines needed.
FeVer Beverages is a typical coffee shop that operates at Batangas. Recently, the general manager is facing a challenge about not meeting their target lead time of serving the hot coffee of 15 minutes. The lead time starts from order taking until order serving. The staffing model of the shop has one cashier, one barista and a guard. The number of staff, equipment, and raw materials have been found sufficient. Based on the initial data analysis, the volume of customers has been stable. Because there is a need for the lead time to improve as to retain its customers and to even grow, a problem-solving effort has been started using the Lean Six Sigma DMAIC approach. Using the FEVER Beverages, you should create your own Project Charter and SIPOC Diagram.
as the staff director of a new hospital, you are planning to hire cardiologists rehabilitation and infectious diseased specialists. according to recent data, each cardiology case averages $ 12,000 in revenue, each physical rehabilitation case $19,000, and each infectious diseased case, $14,000. you judge that each specialist you employed will expand the hospital caseload by about 10 patients per week. You already have 3 cardiologists and rehabilitation specialists bring in one government researched per year, while each infectious diseased specialist brings in three. Your board of directors would like your weekly revenue to be as large as possible. How many of each kind of specialist should you hire? a. State the LP in standard form, defining all variables? b.

The ore of a gold mine in the Mountain Province contains, on the average, 2 gram of gold perton. One method of processing cost ₱1,800.00 per ton and recovers 90% of the gold, whileanother method cost only ₱1,400.00 per ton and recovers 85% of the gold. If the gold can besold at ₱8,000.00 per gram, which method is better and by how much?
The College of Business and Public Administration at Benton University has a copy machine on each floor for faculty use. Heavy use of the five copy machines causes frequent failures. Maintenance records show that a machine fails every 2.5 days (or l = 0.40 failure/day). The college has a maintenance contract with the authorized dealer of the copy machines. Because the copy machines fail so frequently, the dealer has assigned one person to the college to repair them. The person can repair an average of 2.5 machines per day. Using the finite-source model, answer the followingquestions: a. What is the average utilization of the maintenance person?b. On average, how many copy machines are being repaired or waiting to be repaired?c. What is the average time spent by a copy machine in the repair system (waiting and being repaired)?
• Use this information for the question below. Low-Grade Copper Ore $571 per Ton High-Grade Copper Ore $843 per Ton Coloma Cooper Incorporated is able to produce $640 worth of copper from one ton of low-grade copper ore. Because of its higher copper content, Coloma can produce $940 worth of copper from one ton of high-grade copper ore. A mining company is offering to trade 7,250 tons of low-grade copper ore for 5,000 tons of high-grade copper ore. Assuming Coloma currently has 5,000 tons of high-grade ore, what should it do?
The Schmedley Discount Department Store has approximately 300 customers shopping in its store between 9 A.M. and 5 P.M. on Saturdays. In deciding how many cash registers to keep open each Saturday, Schmedley’s manager considers two factors: customer waiting time (and the associated waiting cost) and the service costs of employing additional checkout clerks. Checkout clerks are paid an average of $67 per hour. When only one is on duty, the waiting time per customer is about 10 minutes (or hour); when two clerks are on duty, the average checkout time is 6 minutes per person; 4 minutes when three clerks are working; and 3 minutes when four clerks are on duty. Schmedley’s management has conducted customer satisfaction surveys and has been able to estimate that the store suffers approximately $10 in lost sales and goodwill for every hour of customer time spent waiting in checkout lines. Using the information provided, determine the optimal number of clerks to have on duty each Saturday to…
A company producing a standard line and a deluxe line of dishwashers has the following time requirements (in minutes) in departments where either model can be processed. Standard Deluxe Stamping 3 6 Motor Installation 10 10 Wiring 10 15 The standard models contribute $20 each and the deluxe $30 each to profits. Because the company produces other items that share resources used to make the dishwashers, the stamping machine is available only 30 minutes per hour, on average. The motor installation production line has 60 minutes available each hour. There are two lines for wiring, so the time availability is 90 minutes per hour. Write the formulation for this linear program. What are the optimal daily production quantities of each product and the optimal daily profit?
Management of High Tech Services (HTS) would like to develop a model that will help allocate their technician’s time between service calls to regular contract customers and new customers. A maximum of 80 hours of technician time is available over the two-week planning period. To satisfy cash flow requirements, at least $800 in revenue (per technician) must be generated during the two-week period. Technician time for regular customers generates $25 per hour. However, technician time for newcustomers only generates an average of $8 per hour. To ensure that new customer contracts are being maintained, the technician time spent on new customer contracts must be at least 60% of the time spent on regular customer contracts. Given these revenue and policy requirements, HTS would like to determine how to allocate technician time between regular customers and new customers so that the total number of customers contracted during the two-week period will be maximized. Technicians require an…
The Cove is a midsized furniture store. Sales staff are assigned standard shifts (1st shift usually takes place between the hours of 9 a.m. and 5 p.m. 2nd shift is worked between 5 p.m. and 1 a.m. 3rd shift typically takes place between the hours of 12 a.m. and 8 a.m.), and the number of customers arriving per shift averages 40, Poisson distributed. A salesperson can deal with one customer in 5 minutes on average and costs the company $100 per shift in salaries and fringe benefits. Service times closely follow an exponential distribution. The manager is reviewing the number of salespersons to schedule for each shift. The cost of customers waiting before they receive service has been estimated at $2 per minute in terms of lost sales and loss of goodwill. a. If management wants to minimize the cost of both sales staff and customer wait times, how many salespersons should be working in each shift? b. What is the cost per shift to the company if they use the number of salespersons you…
