Vikiki Furniture, Inc. produces all types of office furniture. The "Executive Secretary" is a sofa-bed that has been designed using ergonomics to provide comfort during long work hours. The sofa-bed sells for $138. There are 580 minutes available during the day, and the average daily demand has been 65 items. There are eight tasks: Task performance time (min) task must follow task listed A 4 -- B 7 -- C 6 A, B D 5 C E 6 D F 7 E G 8 E H 6 F, G Total 49 min What is the Cycle time for this operation?
An electricity power plant was redesigned so that the old system consisting of a single large display screen which could be seen by all of a team of three operators was replaced by individual workstation screens for operators. This worked well until there was a problem which resulted in dangerous gases being released. The team of operators had great difficulty in finding the source of the problem and deciding what to do. Because they no longer have access to all the information, they have to spend time explicitly co-ordinating their understanding of the situation by talking to each other. Under the old system, the knowledge would be shared – one operator would know what was happening with another’s area of the plant without explicit communication. Although the team’s individual responsibilities would still have been clearly divided, the knowledge of the system would be shared. How could the new system of individual workstations be modified to make better use of distributed cognition?

A linear programming computer package is needed. EZ-Windows, Inc., manufactures replacement windows for the home remodeling business. In January, the company produced 15,000 windows and ended the month with 9,000 windows in inventory. EZ-Windows' management team would like to develop a production schedule for the next three months. A smooth production schedule is obviously desirable because it maintains the current workforce and provides a similar month-to-month operation. However, given the sales forecasts, the production capacities, and the storage capabilities as shown, the management team does not think a smooth production schedule with the same production quantity each month possible. February March April Sales forecast 15,000 16,500 20,000 Production capacity 14,000 14,000 18,000 Storage capacity 6,000 6,000 6,000 The company's cost accounting department estimates that increasing production by one window from one month to the next will increase total costs by $1.00…

XYZ Company produces and sells 2 products, Lambda and Gamma, and the production process goes through two departments. Traditionally Manufacturing Overhead (M/O) cost is applied on the basis of direct labor hours (DLH); estimated M/O cost is $ 5,757,500 and the estimated DLH is $12,250 for the most recent period.The team decided to replace traditional plantwide costing system to activity-based costing system. There are 3 activity cost pools which represent 3 activity areas at the plant. Direct Labor wage rate is $ 30 per hour. Compute total cost per unit (for lambda and gamma) using activity-based approach. (round your numbers).
Personnel Planning; TDABC Recent competitive pressures have caused National InsuranceCompany to examine policies regarding personnel planning. As a start, the company has decided toexperiment with and develop a time-driven ABC model for its claims processing center.A study of this support center indicates the following three primary activities: remote processingof customer claims, 0.5 hour; onsite processing of customer claims, 1.0 hour; and updating/maintaining customer records, 0.2 hour. Onsite processing is required for larger claims, while remote processing is done for smaller claims. (For onsite processing, assume—for simplicity—that the claimsprocessors use their own automobiles.) All claims will require that the customers’ records be updated.The claims processing center currently employs three full-time employees. Total annual cost ofthe center (salaries, depreciation, utilities, etc.) is estimated at $255,000. The net amount of availablepersonnel time per year for this…
The assembly line process for a manufacturing company requires the completion of eight tasks to assemble one unit of a product. The table below shows the task numbers, task times, and precede tasks. The diagram below show the precedent relationships for the eight tasks. The company CEO set a target throughput rate of 400 units per day. The company’s factory design plan calls for the assembly line to operate 7.2 hours a day for five days a week. Task # Task Time (seconds) Task Time (minutes) Preceding Tasks #1 14.0 0.23 None #2 26.0 0.43 #1 #3 10.0 0.17 #2 #4 18.0 0.30 #1 #5 23.0 0.38 #4 #6 12.0 0.20 #5, #7 #7 25.0 0.42 None #8 20.0 0.33 #3, #6 Sum 148.0 2.47 If the assembly line described in Question #6 is balanced using the “shortest task time first” decision rule, which of the following set of tasks will be assigned to the first workstation of this assembly line?
