Process simulation is an effective tool when used to simulate a system where a great deal of data exists for the process. This technique is however limited when it comes to simulating certain non-deterministic parts such as human behaviour and interaction, for which there may not be a great amount of data available. This work creates a unique hybrid model through the combination of process simulation with agent based simulation that simulates the non-deterministic parts of the process, as well as the deterministic parts. An actual industrial system forms the basis for the research, and the hybrid model is used to understand the effects that human deterioration has on the productivity of this system, as well exploring different scenarios that could lead to improved performance.

The electrochemical properties of 4-[(anthracen -9-ylmethylene)-amino]-1, 5-dimethyl-2-phenyl-1,2-dihydro-pyrazol-3-one have been carried out using cyclic voltammetry and convolution - deconvolution voltammetry combined with digital simulation technique at a platinum electrode in 0.1 mol/L tetraethyl ammonium chloride (TEACl) in solvent acetonitrile (CH3CN). In switching the potential to positive scan, the compound was oxidized by loss of one electron forming radical cataion followed by fast chemical step and the radical cation loss another two electrons producing trication which followed by chemical reaction (ECEEC). The investigated compound was reduced via consumption of two consecutive electrons to form radical anion followed by fast chemical step and the radical anion gain another electron to form dianion followed by chemical step (ECEC mechanism). The electrode reaction pathway and the chemical and electrochemical parameters of the investigated compound were determined using cyclic voltammetry, convolutive voltammetry and chronoamperometry. The Electrochemical data such as a, ks, Eo , D, and kc of the investigated pyrazole derivative were evaluated expeimentally and verified via digital simulation technique Electrochemical behaviour of the pyrazole compound under consideration was presented and discussed.
