Common use of Qualitative Analysis Clause in Contracts

Qualitative Analysis. On the way towards the quantitative results which we seek our state-space analy- sis delivers qualitative insights about the function of the system being modelled. We list three of the things which we learn here: 1. The system is deadlock-free for all configurations. No binding of service in- stances to service parameters gave rise to a model with a deadlock. 2. The system is livelock-free for all configurations. No binding of service in- stances to service parameters gave rise to a model where states could be visited only a finite number of times (a transient state, in Markov chain terminology). 3. All activities in the model are weakly live. That is, for each activity (such as supload) there is some configuration which allows that activity to occur, although it may be blocked in other configurations. Put more plainly, the SRMC model has no “dead code” (activities which can never occur).
