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 purpose, multinomial Log it regression (MLR) is considered as the basis. Then, the MLR is converted to Poisson GLM with Log link. Two methods including Multivariate exponentially weighted moving average (MEWMA) statistics, and Likelihood ratio test (LRT) statistics are proposed to monitor MLR profiles in phase II. Performances of these three methods are evaluated by average run length criterion (ARL). A case study from alloy fasteners manufacturing process is used to illustrate the implementation of the proposed approach. Results indicate satisfactory performance for the proposed method.

The Shirbit polymetal prospect area is located in 30 km north-east of Ahar city within the Ahar-ore filed in around of Shivardagh batholith. Intrusion of granodiorite igneous bodies into the Eocene trachyte to andesite associated with pyroclastic interlayers caused widespread silicic, argillic and propylitic hydrothermal alteration associated with the Cu, Mo, Pb mineralization as quartz-sulfide (± oxide, carbonate, sulphate) vein and veinlets. Most of chalcopyrite, pyrite and molybdenite veins together with malachite, azurite and iron hydroxides were concentrated in the trachytic-andesitic units with silicic-argillic alteration. The turning point of this study includes investigating the possibility of Log-Log C-P method for separating geochemical anomalies of ore forming elements from the background, accurately determining the cut-off grade, decreasing the area of anomalies, and determining the number of stages of enrichment of elements in the study area compared to the multivariate statistical methods. For this purpose, 85 stream sediment samples taken from a systematic geochemical network were analyzed using ICP-MS method. In order to identify the susceptible mineralization areas by using of concentration-perimeter double Logarithmic method, thee background values and anomalies were separated for each element in the region. Then, elemental anomaly maps were prepared and finally the distribution maps of the ore-forming elements were mapped and the relevant anomalies were distinguished. The results of using C-P fractal method indicates the presence of possible anomalies of Cu, Mo and Ti elements in the eastern, northeastern, and southwest parts of Shirbit area.

In the critical review of the book “Ethics of management” written by Tomas Klikavar (2010), the present article has paid attention to the general approach of the author, the conceptual tools used, and the way of reasoning. According to the author, management, especially business management, due to the importance it attaches to the survival of the organization, has placed its fundamental principle on increasing benefit and earning profit, therefore, morality is not its fundamental issue, and it can even commit immorality in some cases, according to the necessity of tendencies and dispositions . As a theoretician of management ethics, from a historical point of view, the author has tried to show that business management has always been associated with unethical experiences, an experience that has continued until the present day as a kind of modern slavery. He believes that management ethics as an inter-discipline, which is considered a branch of management knowledge in terms of its subject, must be more intertwined with philosophy in practice. Finally, although the author has been able to show the inherent contradiction of management, especially business management, with ethics and provide a solution based on this, the fact that the author has succeeded in presenting a different theory in the field of “management ethics” is a matter of doubt and reflection.
