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…

A Company produces a component for use in the aerospace industry. The component consists of three parts (A, B and C), which are purchased externally and cost 50c, 60c and 70c per piece respectively. Parts A and B are assembled first on assembly line 1, which produces 150 components per hour. Part C undergoes a drilling operation before being finally assembled with the output from assembly line 1. There are six drilling machines in total, but only three are currently operational. Each drilling machine drills part C at a rate of 30 parts per hour. The final assembly line has a production capacity of 100 components per hour. At present, components are produced eight hours a day, five days a week.
If the need arises, management can add a second shift of eight hours for the assembly lines only.
The cost of assembly labour is 40c per assembly operation for each assembly line; the cost of drilling labour is 20c per part. For drilling, the cost of electricity is 10c per part. The overhead cost…

- Quasi-Tech Corporation produces specially machined parts. The parts are produced in batches in one continuous manufacturing process. Each part is custom produced and requires special engineering design activity (based on customer specifications). Once the design is completed, the equipment can be set up for batch production. Once the batch is completed, a sample is taken and inspected to see if the parts are within the tolerances allowed. Thus, the manufacturing process has four activities: engineering, setups, machining, and inspecting. Costs have been assigned to each activity using direct tracing and resource drivers as follows: Activity Expected Cost Activity Driver Activity Capacity Engineering $1,000,000 Engineering hours 5,000 hours Setups 900,000 Setups 200 setups Machining 2,000,000 Machine hours 25,000 machine hours Inspection 800,000 Inspection hours 2,500 inspection hours Quasi-Tech produces two models: Model C and Model D.

- Two vital stages in a production process are assembly I and assembly II. The unit load for the assembly I stage is 7.0 ( 50% higher for high skill) minutes, while it is 10.0 (30 % higher for high skill) minutes for assembly II. There are 7 employees working in assembly I and 8 employees working in assembly II. 65% of low skill labor and 35% of high skill labor are required at both stages. .

- ABC Limited is a manufacturing firm with a workforce of more than 100 employees. Mr Peter has recently joined the firm as the account payable clerk. Miss Emma is the accounting department head, and she is concerned about the cash disbursement system. Therefore, she has asked Mr Peter to analyse the firm's cash disbursement system and identify the internal control weaknesses from the system. Following is the description of the cash disbursement system. In the temporary file, the account payable clerk receives the supplier's invoice and reconciles it with the purchase order. The accounts payable clerk records the purchase in the purchases journal from the clerk's computer terminal and records the liability by adding a record to accounts payable subsidiary ledger.
