A production process at Kenneth Day Manufacturing is shown in the figure below. The drilling operation occurs separately from, and simultaneously with, the sawing and sanding, which are independent sequential operations. A product needs to go through only one of the three assembly operations (the operations are in parallel).

(a) T. Smunt Manufacturing Corp. has the process displayed below. The drilling operation occurs separately from and simultaneously with the sawing and sanding operations. The product only needs to go through one of the three assembly operations (the assembly operations are "parallel"). ASSEMBLY SAWING SANDING 78 min/unit 15 min/unit 15 min/unit WELDING ASSEMBLY DRILLING 25 min/unit 78 min/unit 27 min/unit ASSEMBLY 78 min/unit 1. Which operation is the bottleneck? 2. What is the throughput time for the overall system? 3. If the firm operates 8 hours per day, 22 days per month, what is the monthly capacity of the manufacturing process? 4. Suppose that a second drilling machine is added, and it takes the same time as the original frilling machine. What is the new bottleneck time of the system? 5. Suppose that a second drilling machine is added, and it takes the same time as the original drilling machine. What is the new throughput time?

The drilling operation occurs separately from, and simultaneously with the sawing and sanding operations. Welding starts when both drilling and sanding operations have been completed. After welding, a product needs to go through only one of the three assembly operations (the operations are in parallel, where parallel lines perform the exact same operation). Considering the process times at stations, what is the process time of the system (in min/unit)?
These four steps make up what is called a machine cycle but is more often known as a process loop. When it comes to machine cycles, what factors do most people prioritise? Should I be concerned that I may have to replace machine cycle parts when they wear out? Is it feasible that doubling the number of modules available would make toggling between them easier?
New Mode Y Delay A Yost-Perry Industries (YPI) manufactures a mix of affordable guitars (A, B, C) that are fabricated and assembled at four different processing stations (W, X, Y, Z). The operation is a batch process with small setup times that can be considered negligible. The product information (price, weekly demand, and processing times) and process sequences are shown below. Purchased parts and raw materials (shown as a per-unit consumption rate) are represented by inverted triangles. YPI is able to make and sell up to the limit of its demand per week with no penalties incurred for not meeting the full demand. Each workstation is staffed by one highly skilled worker who is dedicated to work on that workstation alone and is paid $15 per hour. The plant operates one 8-hour shift per day and operates on a 5-day work week (i.e., 40 hours of production per person per week). Overhead costs are $9,000/week.

XYZ is famous for homemade pizzas which are crisp with thin crust and varied toppings giving the pizzas fabulous tastes. XYZ· is revamping its order processing and pizza-making process. In order to deliver fresh pizza fast, six work elements must be completed as shown in the table below :Element Description Precedence Time (in min)A Receive order - 2·0B Shape dough A 1·0C Prepare toppings A 2·0D Assemble pizza B, C 3·0E Bake pizza D 3·0F Deliver pizza E 3·0Construct a precedence diagram for the process.If the demand is 120 pizzas per night (5:00pm to 1:00am), compute the cycle time for the process. Compute the lead time for the process.What is the theoretical minimum number of workstations needed to achieve the required production?How will you balance the production line to produce and deliver 120 pizzas per night? What is the actual minimum number of workstations needed?
Suppose a final assembly is produced by assembling two components. THE The first component, A, is produced internally and goes through three process steps, which are stamping, forging and machining, with scrap estimates of 10%, 15% and 25%, respectively. For every three produced units of component A, two are used in the final assembly and one is separate to meet spare parts needs. The second component, B, which is used exclusively in final assembly, is purchased from a supplier external and inspected on arrival; 2% do not pass inspection. A unit of the component purchased is required for each final assembly. The final assembly process produces 5% of scraps. Spare parts demands for component A and final Su assembly match to 1,000 and 5,000 units, respectively. How many input units are needed for produce component A, and how many units of component B should the firm buy?
True or False: "Bottleneck refers to a stage in a process that limits the capacity of the entire system to produce more."

The diagram below represents a process where two components are made at stations A1 and A2 (one component is made at A1 and the other at A2). These components are then assembled at station B and moved through the rest of the process, where some additional work is completed at stations C, D, and E. Assume that one and only one person is allowed at each station. Assume that the times given below for each station represent the amount of work that needs to be done at that station by that person, with no processing time variation. Assume that inventory is not allowed to build in the system. Al 0.3 min. A2 0.4 min. B 0.75 min. D 0.65 min. 0.60 min. E 0.55 min. What is the average hourly output of the process when it is in normal operation? Average hourly output units
