ase Study No$.1$: Hypermarket XYZ Demand ForecastingContext:Hypermarket XYZ is preparing for the upcoming Festival week by reviewing sales trends from last year to determine adequate inventory levels. Seasonal products like Chicken, Mutton, Eggs, Potatoes, Onion, and Chilies were sold in high quantities during the previous Festival week. However, since then, a new competing hypermarket has opened nearby, creating uncertainty regarding how much demand will be diverted to the competitor.Despite this, the neighborhood around Hypermarket XYZ has seen continued growth, with the hypermarket itself averaging a $1\%$ growth in sales month$-$over$-$month, even after the competitor opened. In preparation for the festival season, Hypermarket XYZ plans to run more advertisements and introduce new deals, expecting a $5\%$ increase in sales compared to the previous year.Demand Forecasting Analysis:$1.$Sales Data from Previous Year:The hypermarket is utilizing historical sales data from last years Festival week to estimate demand for similar seasonal products. This approach aligns with quantitative demand forecasting, specifically time series analysis, where patterns in past data are used to predict future demand$\mathrm{.}2.$Impact of Competition:A new hypermarket opening nearby could shift some demand away from Hypermarket XYZ$.$ To account for this, the hypermarket must adjust its forecast by factoring in competitive conditions. This might involve analyzing competitor pricing, product offerings, and consumer loyalty trends to refine demand predictions$\mathrm{.}3.$Population Growth:Despite the competition, the neighborhoods growing population $($with an average $1\%$ month$-$over$-$month increase in customers$)$ suggests that overall demand may still rise. This demographic change is a key factor influencing demand forecasting, as more households in the area could offset the loss of customers to the competitor$\mathrm{.}4.$Promotional Strategies:Hypermarket XYZ plans to boost advertising and offer new deals, which should further stimulate demand. These marketing strategies are expected to increase sales by $5\%,$ and the forecasting model must incorporate the potential effect of these promotions on customer purchasing behavior.Conclusion:To prepare for the festival season, Hypermarket XYZ can adopt a blended forecasting approach, combining historical sales data with current market trends and competitive analysis. The expected $5\%$ increase in sales, despite the competition, is reasonable given the growing local population and enhanced promotional efforts. However, continued monitoring of competitor activity and customer feedback will be essential to fine$-$tune the forecast and avoid over$-$ or underestimating dem
