- An operation process consisting of 6 operations has the following waste detected in each of them. Determine the production volume that should be considered to cover the final volume of 5,000 per month. Calculate:1.- Quantity of production volume to be produced considering its SCRAP 2.- Quantity of production volume to be made per work shift, considering that the company works 20 days of the month with 3 shifts per day. 3.- Amount of monthly production volume that enter the operation 4. OP % SCRAP 1 .05% 2 .03% 3 .01% 4 .006% 5 .1% 6 .12%A final assembly plant for a certain automobile model is to have a capacity of 240,000 units annually. The plant will operate 50 weeks/yr, two shifts/day, 5 days/week, and 8.0 hours/shift. It will be divided into three departments: (1) Body shop, (2) paint shop, (3) trim-chassis-final department. The body shop welds the car bodies using robots, and the paint shop coats the bodies. Both of these departments are highly automated. Trim-chassis-final has no automation. There are 15.5 hours of direct labor content on each car in this department, where cars are moved by a continuous conveyor. Determine: (a) Hourly production rate of the plant, (b) number of workers and workstations required in trim-chassis-final if no automated stations are used, the average manning level is 2.5, balancing efficiency = 93%, proportion uptime = 95%, and a repositioning time of 0.15 min is allowed for each worker.A machine cycle, also known as a process loop, comprises four components. Which aspects of machine cycles are most valued? Is it necessary to be concerned about replacing individual components of machine cycles? Does the addition of another module assist in resolving the problem of switching between modules?
- . Aquatica makes underwater camera housings for divers. The process begins with a solid rectangular block of aluminum that is used to make a single housing. A computer numerically controlled (CNC) machine drills into the block to make the metal “frame” of the housing. Each block requires 15 minutes of drilling. The frame is then chemically treated in a series of baths. There is ample capacity in the treating stage. Finally, a worker must manually attach the various buttons and components to the metal housing. This assembly takes 120 minutes per housing per worker and Aquatica has 6 workers trained to do this task. The CNC machine requires a 30-minute setup time before the production of a batch can begin. a. If the CNC machine produces 14 housings between setups, what would be its capacity (in housings per hour)? b. Assuming the process is supply-constrained, what is the utilization (as a number between 0 and 1) of the CNC machine if it operates in batches of 14 housings? c. Assuming…Consider the following batch flow process consisting of three process steps performed by three machines. What is the capacity of the process given the following information? Batch size = 50 parts Step 1 - Processing Time = 1 minute/part; Setup time = 20 minutes Step 2 - Processing Time = 2 minute/part; Setup time = no setup Step 3 - Processing Time = 1.5 minute/part; Setup time = no setupPlease can u answer this true and false 1. The design capacity is often lower than the effective capacity. 2. To improve efficiency firms should train employees and correct quality problems. 3. Mass Customization processes are low volume and low variety 4. Process Strategies have long-term effects on efficiency and production flexibility 5. Continuous processes are high volume but a low variety of products. 6. Modules are parts or components of a product previously prepared, often in a continuous process. 7. Effective capacity is the number of units a facility can hold, receive, store, or produce ha pers 8. Utilization is the theoretical maximum output of a system in a given period under idea conctions
- Consider the following batch flow process consisting of three process steps performed by three machines. What is the capacity of the process given the following information?

I understand how you arrived at such answer. However, per my professor's answer key, states an answer of 30 units per hours (which could be wrong and I want to confirm), but my question is - is there any way the answer could be 30 units per hour? Thank you!What is OEE and also calculate the OEE from the given data in below table Items Data Shift Length 8 Hours Breaks (2) 15 minute and (1) 30 minute Downtime 47 minutes ideal Cycle Time 1.0 seconds Total Count 19,271 widgets Reject Count 423 widgetsXYZ company provides labor and space for the manufacturing and assembly operations and stocking various inventory items for production such as wire, cables, some electronic components, etc. XYZ company orders a variety of components and raw materials by contract. The company recently hired 100 part-time employees working four to six-hour shifts. Skilled employees must do several raw material conversions for packaging—there are currently three (3) such employees. The plant layout is a typical process layout - machines of similar types are located together. Each machine and employee must be scheduled over the day and the standard time period for planning is one (1) hour. Material handling is mainly done manually, although the company would like to consider conveyors or other automation to aid in automating their processes. XYZ company forecasts planned production for two (2) years on a rolling quarterly basis. Often, the customer changes the forecast, and these changes can occur as…
