During an eight-hour shift, 750 non-defective parts are desired as a result of a manufacturing operation. The default operation time is 15 minutes. As the operators of machine are inexperienced, the actual time they take to perform the operation is 20 minutes, and, on average, a fifth of the parts that start to be manufactured are lost. Assuming that each one of the machines used in this operation will not be available for one hour in each shift, determine the number of machines needed.
A manufacturing plant produces a product 'A' that requires one unit of 'B' and ½ unit of 'C'. Each unit of 'B' is comprised of one unit of 'D', two units of 'E', and one unit of 'F'. Each unit of 'C' requires ½ unit of 'G' and three units of 'H'. The manufacturing lead times for the components are as follows: 'A' - two weeks, 'B' - one week, 'C' - two weeks, 'D' - two weeks, 'E' - three weeks, 'F' - one week, 'G' - two weeks, 'H' - one week. There are 20 units in stock for each of these components. 100 units of 'A' are needed for delivery in seven weeks: a) Develop the product structure and indexed bill of materials for the product. b) Create a gross and net requirements plan for the manufacturer of the product.
An industrial engineer has designed two alternative methods for accomplishing
a production job. Both methods involve the acquisition of the same working place
and other capital equipment to be used for this job only.
Method A calls for a crew consisting of three men each costing Php30/hr.
This method will result in the production of 10 units per hour of which two will be
reject.
Method B calls for a crew of two men each costing Php35/hr and should
result in the production of eight units per hour of which one will be reject.
The cost of the direct material lost in each reject is Php20. If a certain total
number of units is to be produced find which method is economical?

Until recently, the company had a strong engineering focus and tended to promote people to senior executive positions from the engineering areas. Consequently, almost all of the company's 14 senior executives joined the company over 20 years ago as junior engineers. There is increasing pressure on NewTel to become more market and service oriented. As a result, four people were hired last year from firms to fill new senior executive positions in marketing and service departments. The external hires were necessary because current employees were not sufficiently qualified. Now, there are signs of tension among senior executives, particularly during budget deliberations where there is limited discretionary spending on new corporate activities. The four new hires have been thwarted in their attempts to have the company invest more in marketing and customer…arrow_forward
- There is an upstream Picking department that feeds two downstream Packing departments: Pack Singles and Pack Multis. Those Packing departments feed to a Shipping department that loads the outgoing trucks. 40% of your Pick volume goes to Pack Singles and has a packing rate of 104 units per labor hour (uph). 60% of the Pick volume goes to Pack Multis and has a pack rate of 215 units per labor hour. Your pickers pick both Single and Multi items throughout the day at an overall average rate of 114 units per labor hour. All units that are packed in both processes go through the Ship process at a rate of 570 units per hour.

- Company ZWZ manufactures three products in a serial system; Product XA is manufactured in Stage 1, Product XB in Stage 2, and XC in Stage 3. Product XB has a sales potential in the market; hence, some of it can be sold at the end of Stage 2, and the remaining can be moved to Stage 3. The third stage produces Product XC, and then delivers it to customers. Two units of Product XA produced in Stage 1 are required for each unit of Product XB in Stage 2. In addition, four units of Product XB produced in Stage 2 are required for each unit of Product XC in Stage 3. Stage 1 can only use regular time; however, Stage 2 has the options of using regular time and overtime in manufacturing. On the other hand, Stage 3 has only one alternative, which is subcontracting.
