Given information:
1 worker can assemble the horse sculpture in 16 minutes.
Calculation of flow rate:
Calculation of average inventory:
The total batch size of legs is 400 and the processing time is 2 minutes.
The average inventory is 100 legs.
e)
To determine: The number of body parts that needs to be made to minimize the inventory while not constraining the flow through the assembly.
e)
Explanation of Solution
Given information:
1 worker can assemble the horse sculpture in 16 minutes.
Calculation of batch size:
The target capacity is the flow rate at 3.75 sculptures per hour. There is 1 body in each component set. Therefore, the batch size will be:
The body parts batch size is 12.5 body.
f)
To determine: The number of leg parts that needs to be made to minimize the inventory while not constraining the flow through the assembly.
f)
Explanation of Solution
Given information:
1 worker can assemble the horse sculpture in 16 minutes.
Calculation of batch size:
The target capacity is the flow rate at 3.75 sculptures per hour. There is 4 body in each component set. Therefore, the batch size will be:
The leg parts batch size is 50 leg.

- Cablesplice, Inc.'s manufacturing process consists of five steps: making con- ductors, adding insulation, adding sheathing, irradiation, and printing and coil cuttingUnits are measured in meters. In 970,000 meters of cable, 700 defects were found in the conductors, and 75,000 defects were found in the insulation. In 440,000 meters of cable, 8,930 defects were found in the sheathing, and no defects were found in the remaining two steps.

- A machine makes two components; call them types A and B. It takes 630 seconds to switch production between the component types. During that time, no production occurs. When in production, each unit of A or B requires 0.5 second to be completed. The two components, A and B, are combined in an assembly process to make a final product; call it C. The assembly step can combine the two components into 1 unit every 4 seconds, or 15 units per minute. Suppose the machine rotates between one batch of 2,520 units of A and 2,520 units of B. In that case, what is the capacity of the machine in component pairs per minute, where a component pair is one unit of A and one unit of B?arrow_forwardA machine makes two components; call them types A and B.

After approval, the credit department clerk returns one copy of the sales order to the Sales Department, where it is reviewed and filed. The remaining two copies are sent to the warehouse. The Warehouse clerk picks the goods from the shelves and sends them along with one copy of the sales order to the shipping department. The third copy of the sales order is filed in the warehouse. Upon receipt if the goods, the shipping clerk prepares a shipping notice and sends the goods and one copy of the sales order to the customer.

- A machine makes two components; call them types A and B. It takes 250 seconds to switch production between the component types. During that time, no production occurs. When in production, each unit of A or B requires 0.5 second to be completed. The two components, A and B, are combined in an assembly process to make a final product; call it C. The assembly step can combine the two components into 1 unit every 2 seconds, or 30 units per minute. Assume there is ample demand. If the production schedule could be adjusted with the goal of minimizing inventory in the process, how many units of A should be produced before switching to component B? In other words, calculate the optimal batch size for component A. Assume the same number of units of B would be produced as well. answer:_______unitsarrow_forwardA machine makes two components; call them types A and B.
