According to the assigned case study, Consolidated Electric was faced with an inventory level v. customer service tradeoff. Review the assigned case materials provided and answer the following questions: Design an inventory control system for this business. Provide the formulas that you would use for a P System, Q system or other system you design. Compare these to the formulas currently used. Examine the data from the Appendix to note any peculiarities in demand that your system might encounter. What would you do about them? Describe how the system you have designed will help the company meet customer-service and cost objectives.

Inventory management systems are crucial components of operational efficiency for businesses like Consolidated Electric, especially when balancing inventory levels against customer service requirements. Effective inventory control reduces holding costs, minimizes stockouts, and ensures that customer demands are met promptly. This paper aims to design an appropriate inventory control system tailored to Consolidated Electric's needs, compare it with the current system, analyze demand data peculiarities, and discuss strategies to enhance service and reduce costs.
To begin with, understanding the current system is vital. If Consolidated Electric utilizes a basic reorder point or fixed-order quantity system without sophisticated modeling, implementing a more dynamic inventory control strategy may enhance performance. Common systems include the P system (periodic review) and Q system (continuous review). For this case, designing an appropriate system involves evaluating demand variability, lead times, and cost factors derived from case data and appendix analysis.
The P system, or periodic review system, involves reviewing inventory at regular intervals and placing orders to replenish stock up to a predetermined level. Its formula for the order quantity (Q) is given by:
- Q = (D × T) + (Z × σd × √T) - I
Where:
- D = average demand per period
- T = review period
- Z = service level factor based on desired probabilistic service level
- σd = standard deviation of demand per period
- I = current inventory position
In contrast, the Q system involves continuous monitoring of inventory levels, placing an order when stock drops below a reorder point. Its order quantity typically follows the Economic Order Quantity (EOQ) formula:
- EOQ = √(2DS / H)
Where:
- D = annual demand
- S = ordering cost per order
- H = holding cost per unit per year
The reorder point (R) is calculated as:
- R = dL + Zσd√L
Where:
- d = average demand per day
- L = lead time in days
- σd = standard deviation of demand per day
Comparing these formulas to current practices may reveal differences in how replenishment is scheduled and quantities are determined. If the current system lacks consideration for demand variability or does not incorporate safety stock, integrating these formulas can tighten control and improve responsiveness.
Analyzing demand data from the appendix, peculiarities such as seasonal fluctuations, sudden spikes, or irregular demand patterns must be addressed explicitly. For example, if demand exhibits seasonal peaks, incorporating seasonal indices into demand forecasting enhances accuracy. For demand spikes, safety stock levels should be adjusted accordingly, using the demand variability and desired service levels to compute appropriate safety stock levels:
- Safety Stock = Z × σd × √L
This approach ensures stock availability even during unexpected demand increases without excessively inflating inventory costs.
To improve customer service and reduce costs, the designed system should also incorporate the following strategies:
- Demand forecasting refinement using historical sales data and advanced statistical models such as exponential smoothing or ARIMA techniques for better accuracy.
- Adjusting review periods and reorder points based on demand volatility to prevent stockouts or overstocking.
- Implementing integrated inventory management software that provides real-time tracking and automatic reorder alerts.
- Establishing clear performance metrics such as service levels, inventory turnover rates, and order fulfillment times to continuously monitor and optimize the system.
Furthermore, close collaboration between procurement, sales, and warehouse teams ensures responsiveness to demand changes, thereby aligning inventory levels with customer satisfaction goals while controlling costs.
In conclusion, selecting and designing an appropriate inventory control system for Consolidated Electric necessitates understanding the demand characteristics, evaluating current practices, and incorporating formulas and strategies tailored to demand patterns and cost constraints. Blending the theoretical aspects of P and Q systems with real-world demand data analysis ensures that the company can achieve an optimal balance between inventory holding costs and customer service excellence. Implementing such systems with continuous improvement practices will position Consolidated Electric to meet its strategic objectives effectively.
