Good morning interns,
This is Ms. Gorman from the sales department. We have just secured a new, multi-million-dollar account! We are so good here in the sales department of Heavy-Duty Box Inc. The manufacturing director, Mr. Tsosie, has instructed me to send this problem out to all of you as this will be a deciding factor in which of you get offered the full-time positions available at the end of the internship! Our new client, Beastie Bearings Inc., needs the heaviest duty box we make here at Heavy-Duty Box for their bearings. The following email from Ms. Venegas from Beastie Bearings provides the information you will need. Remember, our mark-up sales price is 150% of what it costs us to manufacture the product. The cheaper it is for us to produce the box, the lower the cost for our client. There is also a grading rubric attached that Mr. Tsosie will be utilizing in evaluating your work. I would advise you to follow it well if you want a position!
Good luck interns,
Ms. Frances…
In a factory where there are three shifts: The machine overhead cost is found to be £8.20 / hr, the labour overhead cost is found to be £30.20/hr, and the premises overhead cost is found to be £3.50/hr.
Using the principle of overhead costing:
If a single component takes 23 minutes to manufacture on the milling machine. What is the cost / part? You should include machine costs, labour costs and premises costs in your answer, but you can neglect material and energy costs.
Express your answer in £ rounded up to the nearest penny.

- A Company produces mechanical probe to update OWSVS (Offensive-Warfare-Support- Vehicle- Systems). For the process of making a mechanical probe, 10 process steps are needed. It is calculated that the scrap rate and rework rate are 12% and 9%, respectively. The average setup time, average machining (operational) time and the average non- operational time can be expressed as: 2.4 hours, 9.6 minutes, and 9.6 hours, respectively. a) With a batch size of 520 mechanical probes, what must be Manufacturing Lead Time (MLT) in hours? b) With 8 hours per shift and two shifts per day, if the plant works 5 days a week, what is the MLT in weeks? c) If the availability factor can be expressed as 81%, then what must be the value of MLT? (in hours and weeks)arrow_forwardSuppose your company has just found $100,000 worth of outdated inventory in an old warehouse (this is the original manufacturing cost). Your boss asks you to consider two options: (1) re-engineer the outdated parts at a cost of $30,000, and ideally resell them for $60,000, or (2) scrap them for $15,000 cash (which is certain) in a second-hand market. What advice would you give your boss? Explain in your own words and give the data that supports your answer.arrow_forwardTask 3: In the context of maintenance costing, planning, and scheduling, clarify the following: What are the general categories of potential maintenance costs? Please provide examples for each category. Also, link this to the field trip you participated in at Al-Nabil factory and explain how these costs are calculated. Explain the practical meaning of the Work Order System for maintenance planning. Please discuss how this approach is used at Al-Nabil Factory. Additionally, emphasize the importance of maintenance planning and its impact on the overall productivity of the plant. Clarify the maintenance inventory management system used at Al-Nabil factory? Please explain its ultimate significance in terms of the factory's availability and overall maintenance costs. Clarify the maintenance inventory management system adopted in Al-Nabil factory and its ultimate significance in terms of factory's availability and the overall maintenance costs.arrow_forward
- A product whose total work content time = 50 minutes is to be assembled on a manual production line. The required production rate is 30 units per hour. From previous experience with similar products, it is estimated that the manning level will be close to 1.5. Assume E = Eb = 1.0. If 9 seconds will be lost from the cycle time for repositioning, determine: The cycle time, and How many workers and Stations will be needed on the line.arrow_forwardBriefly explain the following basic steps in manufacturing processes 1). Marketing 2). Production quality control 3). Sourcing the raw material 4). Design and engineeringarrow_forward(a) There are several reasons why a certain manufacturing process is selected. Explain how time-scale allowed for design and manufacture can influence selection of a manufacturing process. Give one example. (b) Explain how flexibility in production can become an important manufacturing process requirement. Give one example.arrow_forward
- Cushion is an area throughout some workstations & tasks in manufacturing processes. Evaluate the statement below, agree or disagree? "Larger cushion is always better for manufacturing processes"arrow_forwardAnswer all questions please! Will leave a rating!arrow_forwardAn emergency situation has arisen in the milling department, because the ship carrying a certain quantity of a required part from an overseas supplier sank on Friday evening. A certain number of machines in the department must therefore be dedicated to the production of this part during the next week. A total of 1000 of these parts must be produced, and the production cycle time per part = 16.0 min. Each milling machine used for this rush job must first be set up, which takes 5.0 hr. A scrap rate of 2% can be expected. Assume availability = 100%. (a)If the production week consists of 10 shifts at 8.0 hr/shift, how many machines will be required? (b)It so happens that only two milling machines can be spared for this emergency job, due to other priority jobs in the department. To cope with the emergency situation, plant management has authorized a three-shift operation for six days next week. Can the 1000 replacement parts be completed within these constraints?arrow_forward
- Elaborate with examples, The Importance of Machines in human Life.arrow_forwardAs an engineering manager, suppose that the outputs of a company producing fire sensors amounted to 20,000 units in 2009, and that the value of the actual inputs to this company were 200,000 dinars, and the planned production for 2009 is 30,000 units. Required: Calculate the efficiency and effectiveness of this company for the year 2009, if you know that there is a production damage rate of 2%?arrow_forwardProvide a definition of Lean Manufacturing and explain why it is important for the training as an Industrial Engineer.arrow_forward
