The product’s popularity is driven by its high-quality ingredients and targeted market-ing campaigns, attracting pet owners across urban and suburban markets. The demanddata for the past six months, carefully recorded to reflect seasonal trends, promotionaldiscounts, and pet adoption events, is presented in the table below. Accurate forecastingis critical for the manufacturer to manage raw material procurement, schedule produc-tion runs, and coordinate logistics with distributors, ensuring pet stores are well-stockedwithout excess inventory that could increase storage costs.Table 1: Monthly Demand Data for Premium Dog Fooda) Using a 3-month simple moving average, calculate the forecasted demand for month7 to guide the manufacturer’s production planning.b) Using exponential smoothing with a smoothing constant of 0.2 and an initial fore-cast for month 1 of 1,200 bags, calculate the forecasted demand for month 7 .
Question 4: Production Scheduling for a Furniture Assembly Workshop
A specialized furniture assembly workshop produces two types of wooden chairs, ModelX and Model Y, on a single assembly line to supply home furnishing retailers. Theworkshop operates in a competitive market, requiring precise scheduling to meet deliverydeadlines and maintain customer satisfaction. Producing Model X chairs takes 0.9 hoursper unit due to detailed craftsmanship, while Model Y chairs require 1.3 hours per unitbecause of additional finishing processes. Switching the assembly line from Model X toModel Y requires a setup time of 3.5 hours to reconfigure tools and adjust workstations,while switching from Model Y to Model X takes 2.5 hours. The workshop must produce90 units of Model X and 70 units of Model Y in a week to fulfill a major order, withthe assembly line available for 55 hours per week. The production manager needs tocalculate key scheduling metrics to optimize the production sequence, prioritizing thesequence that minimizes setup time to maximize efficiency and meet deadlines.
Calculate the total production time required for 90 units of Model X and 70 unitsof Model Y, excluding setup times.
Calculate the total time (production + setup) required to produce the requiredunits, using the sequence that minimizes setup time.
Question 5: Process Flowchart for Furniture Assembly
Based on the production process described in Question 4, draw a detailed flowchart toillustrate the sequence of steps for producing Model X and Model Y chairs in the furnitureassembly workshop. The flowchart should include the following steps: receiving raw ma-terials (wood and hardware for both chair models), setting up the assembly line for ModelX, producing Model X chairs, setting up the assembly line for Model Y, producing ModelY chairs, inspecting finished chairs, and packaging for delivery. Incorporate decisionpoints for selecting which chair model to produce first, handling defective units (assumea 4% defect rate for both models), and looping to process additional . Clearly
