At the beginning of fall you currently have 30 workers, but you plan to hire temporary workers at the beginning of summer and lay them off at the end of summer. In addition, you h

Conclusion Aggregate planning provides the link between the corporate strategic and capacity plans and workforce size, inventory quantity. and production levels. It does not involve detailed planning. It is also useful to point out some practical consideration – in aggregate planning. First, demand variations are a fact of life, so the planning system must include sufficient flexibility to cope with such vari

Pres old Capacity

Pres old Capacity A final requirement for the successful implementation of yield management is that the lowerpriced capacity can be sold in advance. This limits the availability of capacity to the high erpriced market segments. As an illustration, hotels usually work with conference planners several years in advance of a conference, offering a given number of rooms at the lowest room rates. Travel groups usually pl

Product Perishability

Product Perishability The underlying reason that yield management can be applied to many types of services is the perishability of service capacity. In other words, service capital cannot be saved for future use. (Wouldn’t it be great if the airlines could save all of their empty seats during the year for use during the Thanksgiving and Christmas holiday periods! I Given that capacity in a service operation

High-Fixed and Low- Variable Costs

High-Fixed and Low- Variable Costs High-fixed and low-variable co ts allow a firm to offer significant discounts while still being able to cover variable costs. When a service firm has this type of cost profile, profits are directly related to sales. In other words, the more sales generated. the more profits made. For example, if the variable cost associated with having a hotel room cleaned is estimated at $25 (w

Yield Management

Yield Management Aggregate planning in services is very different from that in manufacturing. This is due, in large part, to the fact that the capacity of service operations is often viewed as highly perishable  because it cannot be saved or inventoried for future use. For example, the empty seats in a restaurant on Monday morning cannot be saved for use on Saturday night when  it is very busy. Thus. services d
