The lead time is 2 weeks. The current on hand inventory, at the beginning of week 1 is 360 units. If the order
cost is $540 per order and the inventory cost is $3 per unit per period, and the order quantity is the computed
part period (or a multiple of the computed part period) when it is necessary to place an order, what is the total
cost for the 8 week period? Report as a whole number with no commas.
Answer:
The correct answer is: 4590
A company uses various machines in the preparation of ice cream. The firm has been successful until recently when it noticed growing repair expenses for the various machines it uses. Over the past 20 months, the machines have broken down at the rate indicated in the following table:
Each time a machine breaksdown, the company estimates that it loses an average of US$300 in production time and service expenses. Should the company opt to purchase a service contract for preventive maintenance by Angeles Machineries Inc., (AMI) there will still be breakdowns, averaging one breakdown per month. The price for this service by AMI is US$150 per month.
a. If the company continues as is, what is the expected no. of breakdowns based on past history?
b. What will be the cost of breakdowns per month to the company without a preventive maintenance contract?
c. What will be the cost of breakdowns per month to the company with a preventive maintenance contract?
d. Should they engage the…
1) An electric motor’s torque is a function of the speed at which it rotates. Many brushed AC motors have a linear toque curve as shown below. If the power output of the motor is equal to the torque (T) multiplied by the rotational speed in rad/s (w), what is the maximum power you can get out of the motor if the stall torque (Tstall) is 0.001 Nm and the no load speed (wno load) of 10,500 RPM? Give answer in Watts.

- Consider the following tasks that must be assigned to four workers on a conveyor-paced assembly line (i.e., a machine-paced line flow). Each worker must perform at least one task. There exists unlimited demand unless stated otherwise.

Supplies of any amount can be had at any required time but each ordering costs Rs. 50/-. Cost of holding the commodity in inventory is Rs. 2/- per unit per day while the delay in the supply of the item induces a penalty of Rs.10/- per unit per delay of one day.

Parts arrive following EXPO(5) distribution. Upon arrival, the parts will be send to the shops where they will be processed, each part will be transported individually (assume the parts move by themselves without the need of a resource) and the move time takes UNIF(2, 3) minutes. Once the parts arrive at the shop station the parts are distributed among the machines by selecting the machine with the shortest queue, if there are ties, then the tie breaker is the machine index (Machine 3 is prioritized over machine 2, and 1, and machine 2 is prioritized over machine 1). There is no maximum buffer capacity to be considered. Processing time for each machine is constant and is equal to 7 minutes. All three machines have failure modes; the machines have up times and down time as following: Machine 1 Up Time expo(140) min, Down Time UNIF(S, 10) min, Machine 2 up time EXPO(100) min and down time UNIF(S, 15) + 5 min while for machine 3 up time…arrow_forward
- True, False or Uncertain. Explain your answer. Own wage elasticity JELLlincrease if product demand elasticity n? is high. In short run, when there is an increase in wage rate, each firm will hire less labor and so the industry labor demand is simply the horizontal summation of firm's labor demand. а. b. Labor demand is represented by the marginal revenue produce schedule (MRP) when we have competitive product market while it will be represented by the value of marginal product schedule (VMP) when we have a product market monopolist. When elasticity of substitution, SLK, increase that means the L and K are less substitutable, and the isoquant will be L-shaped.

The forecast for the fourth year was 876 units.

A typical part is processed sequentially through 10 machines in batch sizes of 1. The shop contains a total of eight conventional machine tools and operates 40 hr/wk of pro duction time. Average time values on each part per machine are: machining time = 0.5 hr, work handling time = 0.3 hr, tool change time = 0.2 hr, setup time = 3 hr, and non operation time = 12 hr. A new programmable machine is being considered that can per form all 10 operations in a single setup. The programming of the machine for this part will require 20 hr; however, the programming can be done off-line, without tying up the machine. Setup time will be just 2 hr because simpler fixtures will be used. Total machining time will be reduced to 80% of its previous value due to advanced tool control algorithms; work han dling time will be the same as for one machine; and total tool change time will be reduced by…arrow_forward
