Engineering design is a sequential process such that the design team will need to complete one complete cycle before revisiting the earlier step for potential revision.

2.1 You are tasked with planning of maintenance tasks at a water treatment facility. A critical pump has failed unexpectedly, causing significant downtime. Meanwhile, another pump of the same type has been operating without any issues. Illustrate using a diagram the planning process that highlights the difference between a maintenance task for an asset that has failed and a maintenance task that prevents failure from occurring. (6) 2.2 You are the working at a power generation plant. Over the past six months, the plant has experienced inconsistent performance from its critical assets, resulting in occasional production losses. The maintenance team recently implemented a new maintenance strategy to address this issue. Indicate the different methods to consider when assessing the effectiveness of the maintenance strategy. (3) 2.3 At a manufacturing facility, operators are primarily responsible for running production equipment, while the maintenance team handles all repairs and…

Company ABC is planning to introduce a new advanced model for their Juice Maker product. The process is mainly fabrication of parts followed by assembly of the final product. The design team of the company is assigned to perform the following tasks. Show how the data is obtained (survey, literature, actual from records). Justify any assumptions used in your analyses. Strategy 1. To set strategy of the operation function based on the following: a. Quality as OQD and cost as OWD. b. The company position itself based on cost. c. The company policy of minimizing use of natural materials to be adopted and deployed. Product Design 2. To design the new model of the product based on the following analyses: a. Use of QFD as a design tool.

Suppose that a company needs 1,600,000 items during a year and that preparation for each production run costs $500. Suppose also that it costs $23 to produce each item and $4 per year to store an item. Use the inventory cost model to find the number of items in each production run so that the total costs of production and storage are minimized.

Operational research is a scientific approach for decision making that seeks to determine the best design under the constraints. Select one: O True O False

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 manufacturer has the following data regarding a product: Fixed cost per month = Rs. 50000 Variable cost per unit = Rs. 200 Selling price Per unit = Rs. 300 Production capacity = 1500 units per month If the production is carried out at 80% of the rated capacity, then the monthly profit (in Rs.) is

CAD process is the subset of design process. true O false

Inventory Control A company anticipates there will be a demand for 20,000 copies of a certain book during the next year/. It costs the company $0.50 to store a book for 1 year. Each time it must print additional books, it costs $200 to set up the equipment. NOTE: We assume that the demand is uniform. Let • x= number of books printed during each printing run ● y= = number of printing runs

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. Minimum wage imposed by the government is always bad for the economy because it increase unemployment and deadweight loss. с. d. e. 3.

Quality has been defined as customer satisfaction (or "fitness for use"). Quality can also be defined as "conformance to specifications". In theory, if you create the right specifications and then manufacture a product that meets these specifications, you should achieve customer satisfaction.  Consider the following four scenarios for a particular product: A) Conforms to specifications and is competitive in its adequacy.   B) Conforms to specifications and is not competitive in its suitability.    C) It does not conform to specifications and is competitive in its education.   D) Does not conform to specifications and is not competitive in its education.   Which of these are not, in theory, feasible, but in practice occur and cause a lot of conceptual confusion?  Can you cite some examples?

Q#1: Discuss benefits of Quality and explain Dimension of Quality which helps us to select any product or services for any organization in your own words.

A factory production department consists of a large number of work cells. Each cell consists of one human worker performing electronics assembly tasks. The cells are organized into sections within the department, and one foreman supervises each section. It is desired to know how many work cells should be assigned to each foreman. The foreman’s job consists of two tasks: (1) provide each cell with a sufficient supply of parts that it can work for 4 h before it needs to be resupplied and (2) prepare production reports for each work cell. Task (1) takes 18 min on average per work cell and must be done twice per day. The foreman must schedule the resupply of parts to every cell so that no idle time occurs in any cell. Task (2) takes 9 min per work cell and must be done once per day. Neither the workers nor the foreman are allowed to work more than 8 h/day. Each day, the cells continue production from where they stopped the day before. (a) What is the maximum number of work cells that…

Assignment A company manufactures two products X and Y, which require the following resources. The resources are the capacities machine M1, M2, and M3. The available capacities are 50, 25, and 15 hours respectively in the planning period. Product X requires 1 hour of machine M2 and 1 hor of machine M3. Product Y requires 2 hours of machine M1, 2 hours of machine M2 and 1 hour of machine M3. The profit contribution of products X and Y are $ 5 and $ 4 respectively. 1- Formulate the above problem as (LP) and set up the standard linear programming model and represent the information in a table. 2- Solve the problem by using the graphic method.

Inventory Control and Planning Lehen Vinters imports a certain brand of beer. The demand, which may be assumed to be uniform, is 1,250,000 cases/year. The cost of ordering a shipment of beer is $500, and the cost of storing each case of beer for a year is $2. Determine how many cases of beer should be in each shipment if the ordering and storage costs are to be kept at a minimum. (Assume that each shipment of beer arrives just as the previous one has been sold.)

The M–N plant manufactures two different products: M and N. Selling prices and weeklymarket demands are shown in the following diagram. Each product uses raw materialswith costs as shown. The plant has three different machines: A, B, and C. Each performsdifferent tasks and can work on only one unit of material at a time.Process times for each task are shown in the diagram. Each machine is available2,400 minutes per week. There are no “Murphys” (major opportunities for the system tofoul up). Setup and transfer times are zero. Demand is constant.Operating expenses (including labor) total a constant $12,000 per week. Raw materialsare not included in weekly operating expenses.a. Where is the constraint in this plant?b. What product mix provides the highest proi t?c. What is the maximum weekly proi t this plant can earn?
