# Conception for a simultaneous capacity and price control

Chapter

## Abstract

The design of a concept for SCPC needs, firstly, the specification of the requirements for SCPC as a method for RM in the context of the revenue maximization problem. This includes the description of the addressed planning levels, which have to be considered in the SCPC and the planning tasks that have to be executed. Following the central planning tasks of RM, its underlying application constraints are outlined. The formulation of the objective system of SCPC leads to several problems influencing the operational design of the solution concept. The development of the solution and its first areas of application indicate the appropriate implementation of SCPC.

*Forecasting*is the prediction of an event, a state or a development over time. Qualitative and quantitative forecasting techniques can be distinguished. In this context, especially quantitative methods are relevant. Examples are exponential smoothing, regressions or various autoregressive and moving-average methods [Lancaster/ Salkauskas 1986; Schlittgen/Streitberg 1987; Bamberg/Baur 1998, pp. 217; Tempelmeier 2005].Google Scholar - 41.Corsten/ Stuhlmann [1998] and especially Fandel/Blaga [2004] discuss the external factor as a difference criterion between the service and production industries.Google Scholar

- 49.A classical example for the setting of aspiration levels is the conduction of offensive or defensive environmental protection in companies. With the given competing objectives “profit margin maximization” and “pollution minimization”, an offensive protection strategy would be to minimize pollution under the constraint of a minimum profit margin. The defensive alternative is to maximize the profit margin under consideration of maximum pollution levels [see Wagner 1990, p. 14].Google Scholar

*Simulation*is the reproduction of time-related processes in a model, in order to draw conclusions about the behavior of a real system [see VDI 1993]. Conventional simulation methods can be found in Fujimoto [1999].Google Scholar - 58.A
*knapsack problem*is a problem in combinatorial optimization. Given a set of items with a specific cost and value, the problem is to determine the number of each item that is, for instance, allocated as efficient as possible with respect to a limiting factor (e.g. capacity) [see Martello/ Toth 1990].Google Scholar - 59.Thereby, the functional specifics are non-negativity, continuity, differentiability and the downward slope [Phillips 2005, pp. 40].Google Scholar
- 61.Certain limitations to price differentiation can be stated: Imperfect segmentation (missing knowledge of the willingness to pay of each customer), cannibalization (customers with high reservation prices trying to get lower prices, e.g. discount prices of airlines) and arbitrage actions (third parties buying at low prices and selling the good at a higher price to people with higher reservation prices) [Phillips 2005, p. 77].Google Scholar

*Integer programming*is a special case of linear programming with the unknown variables being integer [Schrijver 1998.]Google Scholar - 67.Thereby, a continuum of possible capacity and price adjustments exists depending on the flexibility and the costs of changing [Talluri/ van Ryzin 2004, p. 176].Google Scholar
- 68.A central problem in the context of RM is thereby the presence of censored (constrained) data where only the accepted requests of customers are stored in the data basis. Rejected offers (from the supplier or consumer side) are not saved. Thus, not the real demand and transaction structure is reproduced in the data. Several techniques are available for the unconstraining of data [Talluri/ van Ryzin, pp. 473].Google Scholar
- 69.The
*price elasticity*of demand ε can be explained as the percent change of demand (in our context the amount of requested capacity units, x) with respect to one percent change in the price (p): ε=†x/x/†p/p. The price elasticity can be the reason for significantly different price levels in different markets despite that the same product is sold. If the demand is price-elastic, even small variations of the price lead to a noticeable change in the demand. A price-inelastic demand does not change with price modifications [Varian 1999, pp. 257].Google Scholar - 70.A
*data warehouse (DW)*is a “subject-oriented, integrated, time-variant, nonvolatile collection of data in support of the management”s decision-making process“ [Inmon/ Hackathorn 1994]. This definition is only one of the various attempts to describe the complex structure of a data warehouse with its typical components of data input (with the important data extraction and transformation process [Bauer/ Günzel 2000]), data management (with the meta-database, the central data base and data marts, as well as the storage system), and the data deployment (use of the data base for the analyses relevant for the operative and communicative CRM) [Devlin 1997].Google Scholar - 71.
*Data Mining*is the automatic knowledge discovery in large databases in order to find complex or complicated patterns with the help of specific data mining techniques (e.g. rule induction, decision trees) [Witten/ Frank 1999; Tan/ Steinbach/Kumar 2005; Hippner et al. 2001].Google Scholar
