A production process at Brianna Bryant 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). 6 units/hr 2.5 units/hr Sawing Sanding Q Assembly 0.8 units/hr Welding 5 units/hr Assembly 0.8 units/hr Drilling 2.1 units/hr a) is the bottleneck. b) The bottleneck time is minutes per unit (round your response to two decimal places). c) The throughput time of the overall system is minutes (round your response to two decimal places). Assembly 0.8 units/hr d) If the firm operates 11 hours per day, 20 days per month, the monthly capacity of the manufacturing process is units (enter your response as a whole number).
What information is not found in the Quantity Schedule section of the cost of production report? Units started into production Total units to account for Cost of units started this period Units transferred to the next department
Each unit of A is composed of one unit of B, two units of C, and one unit of D. C is composed of two units of D and three units of E. Items A, C, D, and E have on-hand inventories of 20, 10, 20, and 10 units, respectively. Item B has a scheduled receipt of 10 units in Period 1, and C has a scheduled receipt of 50 units in Period 1. Lot-for-lot (L4L) lot sizing is used for Items A and B. Item C requires a minimum lot size of 50 units. D and E are required to be purchased in multiples of 100 and 50, respectively. Lead times are one period for Items A, B, and C, and two periods for Items D and E. The gross requirements for A are 30 in Period 2, 30 in Period 5, and 40 in Period 8. Find the planned-order releases for all items
Product Z is made from three units of A, two of B, and four of C. A, in turn, is made of one unit of C and five of D. A customer order was received for 200 units of Z in Week 8.

Moore's Law is used in the construction of ERP. Is Moore's Law still applicable in the modern era?
Examine the diagram, which contains the processing order for a transaction file and a master file for a sequential file update process. Indicate the order in which the transactions are processed. Indicate which master file records are updated and which are read and written, unchanged, into the new master file. Also illustrate the relationship between the transaction file and the master file, that is, T = M, T < M, and T > M, in your answer. How would the update change if a direct access file is used instead?
13. Selecting the victim to be rollbacked to the previous state is determined by the minimum cost. The factors determining cost of rollback is a. How long the transaction has computed, and how much longer the transaction will compute before it completes its designated task. b. How many data items the transaction has used. c. How many more data items the transaction needs for it to complete and how many transactions will be involved in the rollback. d. All of the above
Given the data D = 5000 units, and EOQ = 500, and assuming a 250-day work year. What is the expected time between orders? (value after the full number) Hint: Find the cycle time, multiply with 250-day work year (in days) (rounded).
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?
