Wegmans Bakery produces cheesecake for sale. The bakery, which operates 5 days per week and 52 weeks per year, can produce 40 cakes per day. The bakery sets up cake production operation and produces the predetermined quantity Q has been produced. The setup cost for a production run of cheesecake is $250. The holding cost is $5 per year. The annual demand for cheesecake is constant during the year and is equal to 3900. Determine the following: Round answers to the nearest whole number. (a) the optimal production run quantity (Q). (b) the total annual inventory cost (AHC+AOC). (c) the optimal number of production runs per year. (d) The run length (production run time).
Q. Wegmans Bakery produces cheesecake for sale. The bakery, which operates 5 days per week and 52 weeks per year, can produce 40 cakes per day. The bakery sets up cake production operation and produces the predetermined quantity Q has been produced. The setup cost for a production run of cheesecake is $250. The holding cost is $5 per year. The annual demand for cheesecake is constant during the year and is equal to 3900. Determine the following: Round answers to the nearest whole number. (a) the optimal production run quantity (Q). (b) the total annual inventory cost (AHC+AOC). (c) the optimal number of production runs per year. (d) The run length (production run time).
Calculate total annual production: Calculate the bakery's total annual production capacity.Total annual production = 40 cakes/day ∗5 days/week ∗52 weeks/yearTotal annual production = 40∗5∗52Total annual production = 10400 cakes/year
Use EPQ model for optimal quantity: Use the Economic Production Quantity (EPQ) model to find the optimal production run quantity Q.EPQ formula: Q=(2⋅D⋅S)/H⋅P/(P−D)Where D= annual demand, S= setup cost, H= holding cost per unit per year, P= production rate.First, calculate P, the production rate.P = Total annual production / Total working days in a yearP = 10400 cakes/year / (5 days/week ⋅52 weeks/year)P = Q=(2⋅D⋅S)/H⋅P/(P−D)0P = Q=(2⋅D⋅S)/H⋅P/(P−D)1 cakes/day
Plug values into EPQ formula: Now, plug in the values into the EPQ formula. D=3900 cakes/year, S=$250, H=$5/cake/year, P=40 cakes/day.Q=(2×3900×250)/5×40/(40−3900/260)Q=(2×3900×250)/5×40/(40−15)Q=1950000/5×40/25Q=390000×1.6Q=624.5×1.2649Q=790.14Round S=$2500 to the nearest whole number.S=$2501 cakes
Calculate total annual inventory cost: Calculate the total annual inventory cost AHC+AOC.AHC (Annual Holding Cost) = 2Q×HAOC (Annual Ordering Cost) = QD×SFirst, calculate AHC.AHC=2790×5AHC=395×5AHC=$(1975)
Determine production runs per year: Now, calculate AOC. AOC=7903900×250AOC=4.9367×250AOC=$(1234.18)Round AOC to the nearest whole number. AOC≈$(1234)
Calculate run length in days: Add AHC and AOC to get the total annual inventory cost.Total annual inventory cost = AHC+AOCTotal annual inventory cost = 1975+1234Total annual inventory cost = $3209
Calculate run length in days: Add AHC and AOC to get the total annual inventory cost.Total annual inventory cost = AHC+AOCTotal annual inventory cost = 1975+1234Total annual inventory cost = $3209Determine the optimal number of production runs per year (N).N=QDN=7903900N=4.9367Round N to the nearest whole number.AOC0 runs/year
