Case Scenarios. ‌ In order to see how the contract’s main variables affect the players utilities, it is necessary to propose different scenarios, changing the value of parameters in different ranges. However, not all variables will change in the scenarios. On the contrary, there are parameters that remain constant throughout the project (as mentioned on Section 5.1). Each scenario presented provides results for further analysis on the variables behavior. For this purpose, 6 variables were defined to take into account for all scenarios: Due to the randomness of the variables and strategies, each realization will be composed of 500 iterations of the problem. The number of iterations was verified with variables’ standard deviation convergence, hence, the mean value is a good estimation of the variables distribution.

Case Scenarios. In this section we exemplify the on-off model de­ duced from the SLA and other parameters as described in Sections 4, 5 and 6. A discussion of the sensitivity of the parameters is provided. First we want to recall the main approximations and assumptions used. Appendix A validates the approxi­ mation of the independence of number of failures and the accumulated down times and discusses the insen­ sitivity to fluctuations in the failure intensity. The main assumptions are related to the dependability SLOs given in Section 3.1. Note that SLAs typically define the max­ imum number of failures. In Sections 7.1 and 7.2 we deal with the problem under the assumption of a con­ stant failure intensity, i.e., a homogeneous failure pro­ cess. In Section 7.4 the result from a simulation study is shown, demonstrating that the results obtained are insensitive to fluctuations in the failure intensity. The model of the deployment cost is as given in Section 5. A compensation is assumed to be paid if one or several of the SLOs are violated during an observation interval as described Section 4.
