Textbook Question
Chapter 13.7, Problem 29P
The file P13_29.xlsx contains monthly time series data for total U.S. retail sales of building materials (which includes retail sales of building materials, hardware and garden supply stores, and mobile home dealers).
- a. Is seasonality present in these data? If so, characterize the seasonality pattern.
- b. Use Winters’ method to
forecast this series with smoothing constants α = β = 0.1 and γ = 0.3. Does the forecast series seem to track the seasonal pattern well? What are your forecasts for the next 12 months?

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? (a) Maximize T+C (b) Maximize 120T + 80C (c) Maximize 200T+200C (d) Minimize 6T+5C (e) none of the above According to the information provided in Question 17, which of the following would be a necessary constraint in the problem?

- Menu Planning Instructions Use the following questions and points as a guide to completing this assignment. The report should be typed. Give a copy to the facility preceptor. Submit a copy in your Foodservice System Management weekly submission. 1. Are there any federal regulations and state statutes or rules with which they must comply? Ask preceptor about regulations that could prescribe a certain amount of food that must be kept on hand for emergencies, etc. Is the facility accredited by any agency such as Joint Commission? 2. Describe the kind of menu the facility uses (may include standard select menu, menu specific to station, non-select, select, room service, etc.) 3. What type of foodservice does the facility have? This could be various stations to choose from, self-serve, 4. conventional, cook-chill, assembly-serve, etc. Are there things about the facility or system that place a constraint on the menu to be served?

Record the recipe with which you started and expand it to meet the number of servings required by the facility. Develop an evaluation rubric. Conduct an evaluation of the product. There should be three or more people evaluating the product for quality. Write a brief report of this activity • Product chosen and the reason why it was selected When and where the facility could use the product The standardized recipe sheet or card 。 o Use the facility's format or Design one of your own using a form of your choice; be sure to include the required elements • • Recipe title Yield and portion size Cooking time and temperature Ingredients and quantities Specify AP or EP Procedures (direction)arrow_forwardASSIGNMENT: Inventory, Answer the following questions 1. How does the facility survey inventory? 2. Is there a perpetual system in place? 3. How often do they do a physical inventory? 4. Participate in taking inventory. 5. Which type of stock system does the facility use? A. Minimum stock- includes a safety factor for replenishing stock B. Maximum stock- equal to a safety stock plus estimated usage (past usage and forecasts) C. Mini-max-stock allowed to deplete to a safety level before a new order is submitted to bring up inventory up to max again D.
