OPERATIONS MANAGEMENT: SUSTAIN ACCESS C
- Question 4 Santizit, Inc. produces a constant supply of hand sanitizer bottles (adjusted for seasonality) to its distributors. Recently the sales team increased their forecast to the distributors. With the updated sales forecast, the operations management met to discuss the need to revise their optimal, or economic, order quantity. During the meeting, your manager assigns you to calculate the economic order quantity of cases of hand sanitizer bottles that the plant would need to achieve to meet the forecasted supply to the distributors. The operations supervisor provides you with some key information. • There are 12 bottles in each innerpack. • Each case contains 5 innerpacks. • The average annual holding cost per case is $6. • The cost per order is $130. • The plant operates Monday through Friday and has two weeks per year that it is shut down for maintenance. The maximum inventory at the end of each production run is 4% greater than the demand. • Assume daily demand of 12,703 bottles…arrow_forwardQuestion 3: Jerry has preferences over cats, c, and hats, h, that can be described by u(c, h) = min{2c, 2h}.

The XYZ steel company must determine a policy for ordering coal to operate 15 converters. The ordering cost is $85/order and the cost of holding coal is 15% of the purchasing cost. The XYZ has a contract to obtain the coal for $14 per ton for the coming year. Each converter requires exactly 8 tons of coal per day to operate, and the firm operates 300 days per year. a. Determine the optimal quantity of coal to receive in each order. b. Determine the total inventory-related cost associated with the optimal ordering policy c. Optimal number of orders to place per year and number of operating days between orders, based on the optimal ordering. d. The XYZ is now considering to the following discount policy provided by supplier: Order Quantity (tons) 1,000 - 1,999 Price per ton $14 $12 $10 2,000 - 2,999 3000+ Please help the XYZ to determine the amount the firm should order.arrow_forwardquestion 6 In a Q system, the demand rate for strawberry ice cream is normally distributed, with an average of 295pints per week.The lead time is 8 weeks.
