This thesis was designed specifically for developing the software called multiagent system MAS, that executes high performance concrete HPC mix design with the aim of tackling the arbitrary tedious and time consuming nature of conventional HPC mix designs. The MAS identifies the uses of intellectual autonomous entities called agents, capable of executing commands of which the essence is to use them for HPC mix design. These agents were created through the use of computer programming and coding involving a program language known as Hypertext pre-processor (PHP) with an agent logic strategy, derived following algorithms’ from an artificial intelligence protocol called a table driven system. The conventional mix design procedures of HPC which involves calculations from table readings and graph readings for HPC were converted into codes and fed into the respective agents following an algorithm. On application of the software, the analysis showed that for compressive strengths of HPC 60, 75, 80, and 86 N/mm2 the percentage difference between MAS and conventional HPC mix design for cement alone were 0.03683, 0.06385, 0.06246 and 0.045673 which fall within permissible conditions of ten percent. The results also show that MAS are well suited to carry out HPC mix designs, and when compared with conventional HPC mix design; it is user friendly, simpler, faster and easy to operate. Therefore it can be concluded that multi-agent systems can be effectively used for design and production of HPC than conventional methods which is arbitrary, tedious, time consuming and gives approximate results
