Mr. Elf owns a show store. Currently, he has 10 pairs of shoes that require resoling and polishing. He has a machine that can resole one pair of shoes at a time, and the time required for
the operation varies with the type and condition of the shoe and the type of sole that is used. Shoes are polished on a machine dedicated to this purpose as well, and polishing is always
done after resoling. His assistant generally does the polishing while Mr. Elf does the resoling. The resoling and polishing times (in minutes) are:

1. The first job to be processed is Job
2. The third job to be processed is Job
3. The fourth job to be processed is Job
4. The fifth job to be processed is Job

A serial process has 5 steps – A (4), B(5), C(2), D(6), and E(3) – that have to be performed in this order. The numbers in parentheses are the times (in minutes) needed to process a unit. For each unit produced by this process, the process has a total idle time of:

An order for 200 units of a product is processed on work
centers A and B. The
set up time on A is 45 minutes and the run time is 5 minutes per piece. The
set up time on B is 40 minutes and the run time is 8 minutes per piece. The
wait time between the two operations is 2 hours. The move time between A
and B is 15 minutes. Wait time after operation B is 1 hour and the move time
into stores is 50 minutes. There is no queue at either work station. Calculate
the total manufacturing lead time for the order.

- Modify the machine-to-job assignment model under the assumption that only three of the four jobs must be completed. In other words, one of the four jobs does not have to be assigned to any machine. What is the new optimal solution?arrow_forwardA manufacturing plant produces a product 'A' that requires one unit of 'B' and ½ unit of 'C'. Each unit of 'B' is comprised of one unit of 'D', two units of 'E', and one unit of 'F'. Each unit of 'C' requires ½ unit of 'G' and three units of 'H'. The manufacturing lead times for the components are as follows: 'A' - two weeks, 'B' - one week, 'C' - two weeks, 'D' - two weeks, 'E' - three weeks, 'F' - one week, 'G' - two weeks, 'H' - one week. There are 20 units in stock for each of these components. 100 units of 'A' are needed for delivery in seven weeks: a) Develop the product structure and indexed bill of materials for the product. b) Create a gross and net requirements plan for the manufacturer of the product.arrow_forwardConsider a two-step process that handles three types of customers. Each resourceis staffed by one employee. Type 1 customers spend 5 minutes at resource 1 and 2 minutesat resource 2. Type 2 customers also spend 5 minutes at resource 1, but spend 10 minutes atresource 2. Finally, type 3 customers spend no time at resource 1 and 8 minutes at resource2. Each hour, the demand is 10 customers of type 1, 4 customers of type 2, and 2 customers oftype 3. Where in the process is the bottleneck? What is the flow rate for each customer type?arrow_forward
- A product is completed when 18 tasks are done. These tasks are assigned to 6 workstations (each workstation handling several tasks) in an assembly line set up. All workstations work the same amount of time (= cycle time), and move the (partial) product to the next workstation, and repeat this process. The last workstation generates the finished product. We need 1200 units made every day (= 8 hours). If we run this line with a cycle time of 0.3 minutes, what is the most amount of work (in minutes) that can be done on this product? (Give the answer with one decimal place)arrow_forwardBE Spreadsheet Mike Reynolds has four assignments due in class tomorrow, and his class times are as follows: Time 9 a.m. 12 p.m. 2 p.m. 5:30 p.m. Each class lasts one hour, and Mike has no other classes. It is now midnight, and Mike estimates that the marketing, finance, psychology, and OM assignments will take him one, four, five, and seven hours, respectively. Assume that all time till the last class begins can be spent on completing assignments but each assignment should be done till the time of the class on the same subject. (Mike can prepare assignments for the next classes during previous classes.) Use the Excel Sequencing template to determine how he should schedule the work. Use minus sign to enter negative lateness values, if any. Enter the half an hour value as 0.5, e.g., 3:30 p.m. should be entered as 15.5. If your answer is zero, enter "0". Round your answers for the due date, lateness, and tardiness to one decimal place. Round your answers for the average values to two…arrow_forwardYour team has been assigned to complete 10 client projects over the next two months. These projects and their processing times (time taken to complete a project once started, in days) are described in the table below. In addition, each project has a due-date that has been set by your internal marketing team so that the customers will be delighted with your service if you complete the project by the due-date. However, your team has only enough resources to pursue exactly one project at any given time. Once started, a project is worked through its completion and is not interrupted. As a result of the sequence in which you choose to handle projects, each project will either be on time, or late if it is completed past the due date. If a project is late, the amount of time by which it misses its due-date is called its tardiness. The objective is to pick the sequence in which to complete the projects so as to minimize the total tardiness in the schedule. What is the minimum total tardiness…arrow_forward
- Consider a manufacturing process depicted by the following flowchart. flowchart Station A has 3 parallel operators, A1, A2, and A3. Station C has 2 parallel operators, C1 and C2. Each unit only needs to be processed by one of the operators A1, A2 and A3. After being processed at Station B, a unit then needs to be processed by either C1 or C2. The process time of the individual operators are given as follows. A1, A2, and A3: 12 minutes B: 14 minutes C1 and C2: 6 minutes. The process initiates the production of a new unit every 18 minutes. What is the utilization of Operator C2 in percentage? Note: Provide a number without the % mark. Round your final answer to 2 decimal places if it is not a whole number.arrow_forwardA roller coaster is being designed for a new theme park. Two "trains" are on the track at any given time. One train is being unloaded/reloaded while the other is moving along the track. The track itself takes 10 minutes to complete. The train being loaded should depart before the arriving train is no closer than one minute away. Each car of a train accommodates four people. Loading a car is estimated to take 6 seconds per passenger. Unloading is estimated to take 6 seconds per passenger. Suppose that (unlike actual roller coasters), only one car can be loaded or unloaded at a time. Unloading can NOT occur at the same time as loading. In order to maximize the number of potential passengers, how many cars should the train be made up of? Round your answer to the nearest whole car.arrow_forwardRoedel Electronics produces tablet computer accessories, including integrated keyboard tablet stands that connect a keyboard to a tablet device and holds the device at a preferred angle for easy viewing and typing. Roedel produces two sizes of integrated keyboard tablet stands, small and large. Each size uses the same keyboard attachment, but the stand consists of two different pieces, a top flap and a vertical stand that differ by size. Thus, a completed integrated keyboard tablet stand consists of three subassemblies that are manufactured by Roedel: a keyboard, a top flap, and a vertical stand. Roedel's sales forecast indicates that 7,000 small integrated keyboard tablet stands and 5,000 large integrated keyboard tablet stands will be needed to satisfy demand during the upcoming Christmas season. Because only 500 hours of in-house manufacturing time are available, Roedel is considering purchasing some, or all, of the subassemblies from outside suppliers. If Roedel manufactures a…arrow_forward
