Game-theoretic models of tender's design

We consider $n$-person non-zero sum game related with the design of tender. Players present some projects which are characterized by some vector of parameters. Arbitrator or some juri chooses one of the projects using a stochastic procedure with some distribution function. The winner receives a payoff which depends on the parameters of the project. The game-theoretic model of the tender is presented and the equilibrium in two and three-dimensional models is derived.
