1. A certain batch of parts is routed through six machines in a batch production plant. The setup and operation times for each machine are given in the table below. Batch size is 200 and the average nonoperation time per machine is15 hr.

Suppose the part in the previous problem is made in very large quantities on a production line in which an automated work handling system is used to transfer parts between machines. Transfer time between stations is 30 sec. total time required to setup the entire line is 102 hr. Assume that the operation times at the individual machines remain the same as in the previous problem, Determine (a) manufacturing lead time for a part coming off the line,…
A flow-line mass production operation consists of six manual workstations. Work units are moved synchronously and automatically between stations, with a transfer time of 10 secs. The manual processing operations performed at the six stations take 45 sec, 50 sec, 40 sec, 42 sec, 30 sec, and 55 sec, respectively. Determine (a) cycle time for the line, (b) time to process one work until through the six workstations, (c) average production rate, and (d) time to produce 20,000 units.
A certain job shop specializes in one-of-a-kind orders dealing with parts of medium-to-high complexity. 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…
A company makes two kinds of door Knobs, standard and deluxe ,the making process cost the company 15$ for the standard and 20$ for the deluxe by making on a grinder and a smoother machines, which they can be run for at most 80 hours a week, each standard one needs 2 hours on the grinder, and 4 hours on the smoother, and each deluxe one needs 4 hours on the grinder and 3 hours on the smoother ,the company sales at 25$,35$ for the standard and the deluxe respectively. To have the profit it wants the company decide to make at least 15 knobs from them at a week, formulate the linear programming model?
A toy manufacturing uses 51030 rubber wheels per year for its popular dump truck series. The firm makes its own wheels, which it can can produce at a rate of 800 per day. The toy trucks are assembled uniformly ( at a constant rate ) over the entire year. Carrying cost is $ 1.50 per wheel per year. setup cost for the production run of the wheel is $ 47. The firm operatyes 243 days per year. Determine each of the following: 1-Optimal run size 2-Use your final answer from part 1 to determine minimum total annual cost for carrying and setup 3-Cycle time for the optimal run size 4-Run time
A drug store sells 30 bottles of antibiotics per week.Each time it orders antibiotics, there is a fixed ordering costof $10 and a cost of $10/bottle. Assume that the annualholding cost is 20% of the cost of a bottle of antibiotics, andsuppose antibiotics spoil and cannot be sold if they spendmore than one week in inventory. When the drug store placesan order, how many bottles of antibiotics should be ordered?
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…
A CNC milling machine has a purchase price of £120,000 and it is considered from an accounting standpoint to be depreciated to zero value over a period of 5 years. If the machine is to be used for 2 shifts with each shift working for 37 hours/ week and 45 weeks/ year. What is the machine cost/ hr which must be charged in order to amortise/repay the costs over the 5 year period? To make the calculation simpler, you can assume that over the 5 year period you will be required to pay back 8% interest on the sum borrowed. Express your answer in § / hour rounded up to the nearest penny
A process currently services an average of 59 customers per day. Observations in recent weeks show that its utilization is about 90 percent, allowing for just a 10 percent capacity cushion. If demand is expected to be 70 percent of the current level in five years and management wants to have a capacity cushion of just 4 percent, what capacity requirement should be planned? The needed capacity requirement is nothing customers per day. (Enter your response rounded up to the next whole number.)
Q5: A manager of an inventory system believes that inventory models are important decision making aids. Even though often using an EOQ policy, the manager never considered a backorder model because of the assumption that backorders were “bad” and should be avoided. However, with upper management’s continued pressure for cost reduction, you have been asked to analyze the economics of a backorder policy for some products that can possibly be backordered. For a specific product with D = 1200 units per year, Co = 160, = 4, and = 25, what is the difference in total annual cost between the EOQ model and the planned shortage or backorder model? If the manager adds constraints that no more than 25% of the units can be backordered and that no customer will have to wait more than 18 days for an order, should the backorder inventory policy be adopted? Assume 300 working days per year.
Estimate the effort, time, production and the number of personnel necessary for the development of a Communications system that has a size of 30,000 LDC. In this project there are factors that influence the development and ensure the proper functioning of the system. These are: Complexity of development, staff qualification and advanced knowledge of the language in which it will be developed. Each factor in the order described has a weighted value of 1.15, 0.7 and 0.91 respectively. It is important to mention that the monthly payment per person working in the development is $2,200.
