Solve the Following Problems 1. Workload Balancing Digital Imaging (DI) produces photo printers for both the professional and consumer markets. The DI consumer division recently introduced two photo printers that provide color prints rivalling those produced by a professional processing lab. The DI-910 model can produce a 10cm x 15cm borderless print in approximately 37 seconds. The more sophisticated and faster DI-950 can even produce a 35cm x 50cm borderless print. Financial projections show profit contributions of $42 for each DI-910 and $87 for each DI-950. The printers are assembled, tested and packaged at Di's plant located in Shanghai. This plant is highly automated and uses two manufacturing lines to produce the printers. Line 1 performs the assembly operation with times of three minutes per DI-910 printer and six minutes per DI-950 printer. Line 2 performs both the testing and packaging operations. Times are four minutes per DI-910 printer and two minutes per DI-950 printer. The shorter time for the DI-950 printer is a result of its faster print speed. Both manufacturing lines are in operation one eight-hour shift per day. Requirement: Perform an analysis for Digital Imaging in order to determine how many units of each printer to produce. The recommended number of units of each printer to produce to maximize the total contribution to profit for an eight-hour shift. 2. Production Strategy A local healthfood cooperative runs a community cafe' and produces two vegetarian burgers. The large burger makes a profit of 85 cents per unit sold and the standard burger 55 cents. Each burger is made from three basic ingredients as shown below. The cafe' reckons it never sells more than a total of 100 burgers in any one day (unsold burgers have to be thrown away for health reasons) but that it typically sells at least 30 of the standard burgers every day and 25 of the large. Vegetable mix Soybean mix Crumb mix Large burger Standard burger Availability 30 grams 30 grams 4 kilograms 150 grams 100 grams 10 kilograms 20 grams 20 grams 1.5 kilograms Requirement: Provide management with advice as to what to do to maximize profit in this situation
