(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)?
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?

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?

Solvo produces three types of trucks on one assembly line: the long-haul (L), the short-haul (S), and the vocational truck (V). Next month the company has orders for 1,100 long-haul trucks, 1650 short-haul trucks, and 550 vocational trucks. Chris Riggs, the production manager for Solvo, wants to try uniform production and mixed-model sequencing. Assuming 30 working days per month, what assembly sequence would you recommend, and how many times per day should the sequence be repeated. (Round answer to 0 decimal places) Assembly sequence?

JCL Inc. is a major chip manufacturing firm that sells its products to computer manufacturers like Dell, Gateway, and others. In simplified terms, chip making at JCL Inc. involves three basic operations: depositing, patterning, and etching. • Depositing: Using chemical vapor deposition (CVD) technology, an insulating material is deposited on the wafer surface, forming a thin layer of solid material on the chip. Patterning: Photolithography projects a microscopic circuit pattern on the wafer surface, which has a light-sensitive chemical like the emulsion on photographic film. It is repeated many times as each layer of the chip is built. • Etching: Etching removes selected material from the chip surface to create the device structures. The table below lists the required processing times and setup times at each of the steps. There is unlimited space for buffer inventory between these steps. Assume that the unit of production is a wafer, from which individual chips are cut at a later…
