This paper showcases an improved architecture for a complete negotiation\nsystem that permits multi party multi issue negotiation. The concepts of\nmultithreading and concurrency has been utilized to perform parallel execution.\nThe negotiation history has been implemented that stores all the records of the\nmessages exchanged for every successful and rejected negotiation process and\nimplements the concepts of artificial intelligence in determination of proper\nweights for a valid negotiation mechanism. The issues are arranged in a\nhierarchical pattern so as to simplify the representation and priorities are\nassigned to each issue, which amounts to its relative importance. There is\nrefinement of utilities by consideration of the non-functional attributes. So\nas to avoid overloading of the system, a maximum number of parties are allowed\nto participate in the entire mechanism and if more parties arrive, they're put\ninto a waiting queue in accordance to certain criteria such as the first come\nfirst serve or the relative priorities. This helps in fault tolerance. It also\nsupports the formation of alliances among the various parties while carrying\nout a negotiation.\n
