Here's the what-if scenario: Assume that the LA warehouse becomes temporarily or even indefinitely disabled since facing a large-scale labor disruption. Re-optimize the network considering this new constraint.
Here's the scenario comparison analysis:
Scenario Constraint Scenario vs What-if Scenario
Summary The Constraint Scenario exhibits a higher total cost of $7,424,575.45 compared to the What-if Scenario's total cost of $6,611,905.60, signifying a difference of approximately $812,669.85, which indicates a more expensive operation in the Constraint Scenario. The average service time is slightly higher in the Constraint Scenario (0.72 days vs. 0.70 days), suggesting that the What-if Scenario provides a marginally quicker service. Moreover, the average end-to-end service time…

Here's the what-if scenario: Assume that Dallas plant has lost power. It cannot serve the DCs anymore and has to remain locked indefinitely. Re-optimize the network considering this new constraint.
Here's the scenario comparison analysis:
Scenario Constraint Scenario vs What-if Scenario
Summary In comparing the Constraint Scenario to the What-if Scenario, a few key differences highlight the efficiencies evident in the supply chain. Firstly, the total cost in the Constraint Scenario is lower at $7,424,575.45, while the What-if Scenario incurs a total cost of $7,486,369.12, resulting in a cost delta of $61,793.67. Additionally, although both scenarios exhibit the same average service time of 0.72 days, the What-if Scenario has a more favorable average end-to-end service time of 2.41…

- Employee In-Service Training ASSIGNMENT: In-Service Training. The intern is required to plan and implement two in-service training sessions for employees. Each in-service should last at least 10 but not more than 30 minutes and should be given to all employees affected. The preceptor or supervisor/unit manager must approve all in-service topics. 1) One presentation should be related to a policy or procedure of any kind (e.g. proper use of equipment); 2) The second presentation must be related to sanitation or safety. For each in-service presentation, the intern must develop a written class plan and a visual aid (may be a handout, poster, PowerPoint slide presentation, etc.) appropriate to the life experiences, cultural diversity and educational background of the target audience. The intern must also measure behavior change. Note, this cannot be measured by a written pre- and post- test. That would be measuring knowledge.

- For dietary management in a nursing home. As detailed as possible.arrow_forwardA small furniture manufacturer produces tables and chairs. Each product must go through three stages of the manufacturing process – assembly, finishing, and inspection. Each table requires 3 hours of assembly, 2 hours of finishing, and 1 hour of inspection. The profit per table is $120 while the profit per chair is $80. Currently, each week there are 200 hours of assembly time available, 180 hours of finishing time, and 40 hours of inspection time. Linear programming is to be used to develop a production schedule. Define the variables as follows: T = number of tables produced each week C= number of chairs produced each week According to the above information, what would the objective function be?
