Which type of aggregate plan is preferable when a company produces custom or special purpose equipment, one-of-a-kind items, or highly perishable…

A chase aggregate plan, also known as a demand matching strategy, adjusts production rates to match demand in each period. This is achieved by varying workforce levels or production hours. This strategy is preferable for custom, one-of-a-kind, or highly perishable products because it minimizes or eliminates finished goods inventory. Holding inventory of such items is impractical, impossible, or too costly due to spoilage, obsolescence, or the inability to predict specific customer requirements.

A. A level aggregate plan: This strategy maintains a constant production rate, using inventory to buffer demand fluctuations, which is unsuitable for custom or perishable goods.

C. A hybrid aggregate plan: While a hybrid plan might be used, the pure chase strategy is the most direct and preferable approach for the specific product types mentioned.

D. A modified sales and operations plan: Sales and Operations Planning (S&OP) is the process that creates an aggregate plan; it is not a type of plan itself.

In Chapter 14, "Sales and Operations Planning," the text explains that a chase strategy is ideal for make-to-order firms or those with perishable goods, as inventory cannot be stockpiled.

Chapter 13, "Aggregate Planning and S&OP," contrasts the chase strategy (minimizing inventory) with the level strategy (using inventory), noting the chase approach is common in service organizations and for certain product types.
