b) Geoffrey runs a kitchen that provides food for various canteens throughout a largeorganization. A particular salad is sold to the canteen for R100 and costs R80 to prepare.Therefore, the contribution per salad is R20. Based upon past demands, it is expected that,during the 250 working days per year, the canteens will require the following daily quantities:. On 25 days of the year, 40 salads.. On 50 days of the year, 50 salads.•On 100 days of the year, 60 salads.On 75 days 70 salads.The kitchen must prepare the salads in batches of 10 meals in advance. The manager hasasked you to help decide how many salads the kitchen should supply for each day of theforthcoming year. Setup the payoff matrix for this problem.

5.B) Biona Enterprise usually gets everyday order of a hundred dozen units while the production can make triple amount of the orders. Thus, any surplus must be deposited in the storage with a cost of $9.50 per unit. Once order takes place, the enterprise will serve it within four working days at $200 for the delivery charges. The enterprise works five days a week and closes it operations three weeks per year while keep some stocks approximately 3% of the yearly demand. (a) Find the optimum value of ordering.

Your market research indicates that they want a burger that is loaded with everything as long as it meets certain health requirements. Money is no object to them. The ingredient list in the table shows what is available to include on the burger. You must include at least one of each item and no more than five of each item. You must use whole items (for example, no half servings of cheese). The final burger must contain less than 3000 mg of sodium, less than 150 grams of fat, and less than 3000 calories. To maintain certain taste quality standards you'll need to keep the servings of ketchup and lettuce the same. Also, you'll need to keep the servings of…
Old Pueblo Engineering Contractors creates six-month “rolling” schedules, which are recomputed monthly. For competitive reasons (it would need to divulge proprietary design criteria, methods, and so on), Old Pueblo does not subcontract. Therefore, its only options to meet customer requirements are (1) work on regular time; (2) work on overtime, which is limited to 30 percent of regular time; (3) do customers’ work early, which would costan additional $5 per hour per month; and (4) perform customers’ work late, which would cost an additional $10 per hour per month penalty, as provided by their contract. Old Pueblo has 25 engineers on its staff at an hourly rate of $30. The overtime rate is $45. Customers’ hourly requirements for the six months from January to June are January 5000 February 4000 March 6000 April 6000 May 5000 June 4000 Develop an aggregate plan using a spreadsheet. Assume 20 working days in each month. 12. Alan Industries is expanding its product line to include three…

Demand for stereo headphones and music players for joggers has caused Nina Industries to grow almost 50 percent over the past year. The number of joggers continues to expand, so Nina expects demand for headsets to also expand, because, as yet, no safety laws have been passed to prevent joggers from wearing them.
