You are the project manager for a construction project (maybe capstone design) and you must schedule the various jobs which
must be completed before the project is finished. Some of the jobs can begin immediately but other jobs can only begin after
others are completed. For example, grading can begin immediately but laying a foundation must be delayed until the grading
is completed. The data below are for a project which includes ten jobs; the time it takes to complete each job is known and the
set of jobs which must be completed before each job can begin is known. Your objective is to find a schedule (i.e. beginning
times and ending times) for all of the jobs such that no jobs begins before any of its predecessors are completed and the time
when all jobs are finished is minimized. Formulate a linear programming model to solve the problem.
For the following problem, formulate the Linear program or LP as follows:
1) Define the decision variables and briefly explain the significance of…

Creative Robotics (CR) manufactures two lightweight robots designed for easier house-cleaning. The Alpha-ONE model is older, heavier, and is designed for carpet cleaning. The Alpha-TWO model is newer, lighter, and is designed primarily for wooden floor cleaning. The management team is trying to identify how to minimize the total costs of producing these two models. Their full-time workers consist of primarily manufacturing experts and about 3 people are required to commit themselves to manufacture the Alpha-ONE model and 4 for the Alpha-TWO model, per day. They have a total pool of 100 full-time workers now but are willing to hire more manufacturers if required. Similarly, the Alpha-TWO model is more complex and management has a pool of 20 part-time technical workers to help with the complexity, every day. Again, they are willing to hire more part-time workers if required to assist with the Alpha-TWO model. As far as staff allocations for additional assistance in manufacturing…

- Scheduling Bank Tellers Note: Setup example below in excel and Minimize total daily manpower cost in excel using solver. Mexico City Bank of Commerce and Industry is a busy bank that has requirements for between 10 and 18 tellers depending on the time of day. Lunchtime, from noon to 2 p.m., is usually heaviest. The following table indicates the workers needed at various hours that the bank is open. The bank now employs 12 full-time tellers, but many people are on its roster of available part-time employees. A part-time employee must put in exactly 4 hours per day but can start anytime between 9 a.m. and 1 p.m. Part-timers are a fairly inexpensive labor pool because no retirement or lunch benefits are provided them. Full-timers, on the other hand, work from 9 a.m. to 5 p.m. but are allowed 1 hour for lunch. (Half the full-timers eat at 11 a.m., the other half at noon.) Full-timers thus provide 35 hours per week of productive labor time.

- The newly-established pediatric department of a local hospital is in need of full-time nurses who will work in 8-hour shift per day and part-time nurses who will work in 4-hour shifts per day. Each day is divided into 6 four-hours periods, which requires different number of nurses., as shown in the table below: Time Period Index Time Period Covered 7am - 11am. 11am-3pm 3pm - 7pm 7pm - 11pm 11pm-3am 3am - 7am 1 2 3 4 5 6 Required Number of Nurses 7 9 12 5 4 3 The shifts of full-time nurses can begin at the start of any of the four-hour periods. Hospital policy requires that there must be at least two full-time nurses at each time period. Also, the number of part-time nurses cannot exceed the number of full-time nurses in any time period. Full-time nurses get paid at $160 per shift, while the part-time nurses get paid at $50 per shift. Formulate a linear programming model that will determine the nursing schedule so as to minimize the total cost.arrow_forwardI need solve this please fastarrow_forwardDo not use chatgpt.arrow_forward

Mechanical faults, which can severely reduce output, occur more frequently because people are not involved in much of the production process. These problems need to be caught quickly. One method for discovering these faults is through vibration analysis. Each type of problem generates a different type of vibration. The paper industry uses _____ to determine the type, severity, and location of vibrations in its machinery as well as to create a timetable for maintenance activities.
