In a modern manufacturing system for furniture production, raw material and material, energy and information flows are directly interconnected to obtain competitive products while increasing the productivity, profitability and environmental performance of the enterprise. In the wood industry manufacturing system, raw wood undergoes physical and biological transformation processes (drying and transformation of the biological properties of wood) as well as disruptive actions that are compensated by the order quantities. Energy as a resource has an important role to play in this production process, and it involves consuming a certain amount of energy. It is one of the biggest and costliest resources involved in the manufacturing process. The required energy is generally transmitted from the outside in the form of electric or thermal energy. From the energy input, only a part becomes useful energy, the rest representing energy losses. By reducing energy consumption, reversing energy losses and integrating materials and material losses into energy recovered through retrofitting, revenue and profit can increase, leading to an increase in employee satisfaction. The easier it is to maximize profits and lower the operating costs, the quicker is the recovery of the investments, and that will change in the operating mode in: “WORKING SMARTER NOT HARDER”.
