Em not sure what you mean by "calculates the access to an industrial zone"! what I get is you need different types of users (Admin, Manager, Workers, Storekeeper etc) and every user has a job.
My software will add different types of users and each user have a login, so by that, you can track the activities of each user.
My software can public equipment like a car (with details of car, car owner, engine number etc), then we add number of parking space (example : 50 slots for car parking ) and then assign car to each slot. So we exactly know which car is on which slot so by that we exactly know how much space we have left. Not sure what you mean by " surface of green space" and surface of the industrial zone.
