### Description

Alborz-I as the first phase of the Alborz Observatory Array supposed to study the cosmic ray spectrum around the knee at Sharif University of Technology, Tehran (1200 m a.s.l). In this paper theoretical results obtained from study of the design features, performance, technical characteristic and angular resolution of the Alborz-I consists of 20 scintillator detectors are described. Using a Monte Carlo simulations of showers, the rate of detected events per day and the trigger probability functions are presented for energies around the knee and zenith angles up to 60°. Moreover, the angular resolution of the array in the energy of ~3$\times$10$^{14}$ eV, which contains the most rate of detected events, is estimated.
