A new statistical profile monitoring technique to monitor and detect changes in logistic profiles with an application in the tourism industry is presented in this paper. In the statistical process control literature, profile is usually referred to as a relationship between a response variable and one or more explanatory variables. In the tourism case study presented in this paper, time is consi...

Abstract— In some real case problems, a relationship between a response variable and one or more explanatory variables called as profile is desirable to be monitored over time instead of the response variable itself. There are many techniques in the literature for monitoring the profiles. A special case of the profiles is where the response variable follows a binomial distribution known as Logi...

In certain statistical process control applications, quality of a process or product can be characterized by a function commonly referred to as profile. Some of the potential applications of profile monitoring are cases where quality characteristic of interest is modelled using binary,multinomial or ordinal variables. In this paper, profiles with multinomial response are studied. For this purpo...

In conventional profile monitoring problems, profiles for different products or process runs are assumed to have the same length. Statistical monitoring cannot be implemented until the whole profiles are obtained. However, in some cases, a profile should be monitored when it growth with time, so that the root causes can be identified and automatic compensations can be initiated as early as poss...
