Oct 20, 2021 A set of operational constraints should be respected. Here, these constraints can be clustered into five major categories. Which are demand satisfaction, labour capacity, production facilities, inventory capacities, and decisions that govern inventory levels or outsourcing quantities. Equation represents the demand satisfaction constraints.

Dec 20, 2021 The paper describes an automated method for grinding small ceramic elements using a hyperboloid wheel. The problem of automating the process of machining elements made of nonmagnetic materials with a small area and low height has been solved. Automation of the grinding process was possible thanks to automatic clamping of workpieces in the machining
