Analytical and Simulative Studies


In this chapter, the previous formal and empirical work will be used for conducting analytical and simulative studies on cooperative sourcing behavior and the resulting market effects in order to answer the research questions of this work.

    This represents the main difference between the cooperative sourcing problem and the optimal consortia structure problem from (Beimborn et al. 2004; Fladung 2006). The genetic representation of an OCSP individual comes along with only one row instead of ¦K¦ rows.Google Scholar

    Other approaches are: linearly decreasingPM over time, hyperbolic decreasing PM over time, and hybrid procedures with constant probability during the first periods and decreasing probability after a certain threshold period (Schwefel 1981).Google Scholar

    Furthermore, it should be noted that the optimized library network in (Fladung 2006) consisted of 20 libraries, while the simulation studies in the subsequent sections are conducted with 100 banks and 5 business functions (instead of one procurement process). Thus, the problem size is 25 times larger.Google Scholar
